- Light precipitation threat returns to the area starting
Thursday later afternoon. Most areas will just see drizzle or
rain, but will have to watch for some very light icing Thu
night into early Friday morning north of Interstate 94 in
Wisconsin.
- Well above normal temperatures are expected into next week
with record temperatures forecast for the weekend and
Christmas.
- Additional periods of rain are expected starting Sunday.
Confidence is starting to increase for more significant
precipitation amounts with this system.

.UPDATE...
Issued at 926 PM CST Wed Dec 20 2023
Made some minor changes to the forecast through Friday morning.
Reviewing the upper air data to the south in the moist plume
coming north, the RAP initializations and forecast are a bit too
aggressive with the precipitable water values per 00Z KOUN/KFTW
upper air soundings. Forecasts have also slowed the moist surge
into the area a few hours. This gives a bit of pause with doing
too aggressive a change to the rain chances. However, the
synoptic warm front is really taking shape through northern MO
and low-level saturation is increasing north of the front in srn
IA as evidenced by the 3kft clouds developing. This area will
work north Thursday, along with the low-level warm front. This
focal point of lift and with about 1-1.6km of depth to the low-
level saturated layer, some patchy drizzle will probably
accompany the warm front as ceilings fall into the 800-1200 foot
range by very late afternoon Thu in northeast IA / far swrn WI.
The warm front then progresses northeast with low-clouds and
saturation along it. As overnight temperatures cool, saturation
will increase further in the boundary layer, thus drizzle areas
working northeast look more favorable into Friday morning.
This puts the I-94 and north area on a collision course with
freezing drizzle potential with wet-bulb temperatures near
freezing. Not only is there the warm front but a trough shifting
in from the west out of MN to again cause some light lift for
enhanced collision-coalescence in the saturated layer there. The
latest NBM probabilities of freezing rain suggest a 15-30%
chance of occurrence (over 100 members in that blend). Thus,
continued the glaze of ice possible forecast in northcentral WI
Thu night into Friday morning. This will be one forecast focus
for the overnight shift.

.DISCUSSION...
Issued at 306 PM CST Wed Dec 20 2023
MILDER WITH RAIN LIKELY FOR LATE WEEK:
Sub tropical jet cutting across bottom of upper low off California
coast will eject two minor short wave troughs that will bring some
sensible weather to the area to close out the week. Big picture
suggests highest probabilities for precipitation overall remains
across our southern and eastern areas. Mild temperature regime
should also limit bulk of precipitation to liquid, supported with
latest precipitation type ensemble output. Limited to no impacts
expected.
First wave will be associated with low level moisture advection and
broad lift leading to an increase in clouds overnight into Thursday
morning, especially lower stratus. Probabilities of ceilings under
5kft increase dramatically starting late morning tomorrow according
to 20.12z HREF, climbing well above 80% by afternoon. A browse of
RAP soundings suggest possible drizzle as well with saturated lower
level above a drier layer, but not sure there will be enough
boundary layer lift to generate much. Many of the available CAMS
suggest sort of a speckled solution with light amounts so something
to watch.
Second wave appears a bit stronger but 20.12z guidance suggests it
might track a bit further south than the first. GFS/ECMWF spread
associated precipitation on Friday farther into our forecast area
while NAM would suggest less chances with a more southern track.
Ensemble data still leans towards higher precipitation chances,
ranging from 75-90% in eastern Iowa to southwest Wisconsin, to 20-
40% closer to Twin Cities. While bulk of area should be warm enough
to support liquid, there could be a few hours with a mixed
precipitation threat across parts of north central Wisconsin,
especially Friday morning. Ensemble guidance in Medford, WI area
suggests about a 50-50 split of rain versus freezing rain with light
amounts /and accumulation/ overall. Again, something to watch given
lower confidence of precipitation even spreading that far north to
begin with.
RECORD WARMTH THIS WEEKEND AND CHRISTMAS:
In the wake of the weak shortwaves departing the region Friday,
temperatures will continue to increase this weekend as upper-level
ridging will allow for warm advection to push our temperatures even
further above normal. Little change has been noted in the guidance
over the past 24 hours with the 20.12z EC EFI still showing a very
robust signal for warm temperatures with values of 0.8 to 0.9
for high temperatures over Christmas. Consequently, keeping
forecast current with the latest NBM suggesting highs in the
upper 40s to middle 50s for much of the region this weekend and
into early next week.
Anomalous moisture suggested in guidance is the main instigating
mechanism for some of these ridiculous low temperatures going into
next week. The 20.12z GFS and EC continue to show precipitable
waters of 350% to 400% of normal the night before Christmas.
Consequently, temperatures are not expected to cool much from daily
maximums. As a result, forecast low temperatures on the morning of
Christmas Eve and Christmas reflected in the NBM are from the upper
30s to middle 40s, maybe even some upper 40s in our extreme south.
This is further supported with the 20.12z EC EFI with values of 0.9
to 0.95 for minimum temperatures and a shift tails of 1,
suggesting that these temperatures are well out of the normal.
Therefore, many records likely will be broken, more information
can be found in the climate section.
PRECIPITATION TRENDS FOR CHRISTMAS EVE AND BEYOND:
The upper-level pattern by Christmas depicts an upper-level trough,
digging into the Great Plains region. Generally speaking, the 20.12z
global models show a broad area of surface low pressure developing
south of our region. Confidence is increasing that this could be a
fairly wet pattern with the total QPF from now till mid-week showing
high probabilities (60-100% chance) of seeing 0.5" in the 20.12z EC
ensemble and GEFS from now till next Tuesday evening. Ensembles
disagree a bit more on the exact location of the optimal moisture
axis though. This is shown in the 1" probabilities in the 20.12z
GEFS and EC ensemble where the EC keeps high probabilities (50-90%)
for our region but the GEFS trends them lower (10-50%). Remember
that since these are total probabilities they cover earlier
precipitation as well so would be overdone to a degree.
Another thing to consider is the cold advection behind this system
and how that would play into what our conditions might look like
after Christmas. While it is clear there will be some cold advection
behind this system, it continues to not look that impressive across
deterministic guidance with only somewhat seasonable air being
advected into our region. This is further shown in the 20.12z EC
ensemble showing virtually no probabilities (less than 10%
chance) of 850mb temperatures going below 10C. As for any winter
precipitation on the backside of this system after Christmas,
confidence still remains low. This will be contingent on how the
deformation zone sets up with the departing low which based on
probabilities in both the 20.12z GEFS and EC ensemble for 1" of
snow (10-20% chance), remains a low confidence forecast.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 548 PM CST Wed Dec 20 2023
VFR conditions are expected through the early morning Thursday.
Then, the beginning of a fairly widespread LIFR-IFR-low MVFR
ceiling period as abundant moisture streams north and across the
area. Current observations across eastern KS depict MVFR
ceilings moving northward representing that moisture layer. With
the distance away and slow movement north versus previous
forecasts, have slowed the arrival of MVFR conditions at the
airfields. The MVFR ceilings should move in from the southwest
Thursday overspreading the area. Confidence is lower on IFR at
this time but the 20.18Z HREF guidance would suggest areas south
and west of La Crosse would have the higher probabilities
(60-80%). For now, have lowered ceilings to lower MVFR late
Thursday /20Z/ at KRST. However, IFR probabilities are
increasing every hour after 20Z at KRST, so future TAFs will
include it (after 22.00Z).
The moisture will continue to stream northward and overnight
cooling and weak lift will promote DZ, IFR ceilings, and
lowering visibilities too Thursday night into Friday morning
across the region. This will have greater impacts on aviation
and travel regionally.

Issued at 306 PM CST Wed Dec 20 2023
Based on current forecast trends over Christmas, record high and low
temperatures at La Crosse and Rochester may be challenged with
Rochester having a higher likelihood at achieving records. Below are
some of the temperature records to watch over the holiday period:
* - Record may be challenged
La Crosse

12/25 50F(1936) 38F(1936)* 47F 42F
Additionally, the 1-day precipitation record for Rochester on
Christmas Eve is 0.94" and is 0.75" for Christmas Day. The 1-day
precipitation records for La Crosse are 1.21" for Christmas Eve and
1.61" for Christmas Day.
An interesting note about Rochester`s current record high on
Christmas Eve is that it is the coldest record high at Rochester for
the year tied with January 3rd, 2007. As a result, if the record is
broken on Christmas Eve, January 3rd would have the definitive
coldest record high at Rochester of 41 degrees.

.KEY MESSAGES...
- Fog issues (including at least some dense fog) these next few
nights/mornings:
Although there is still some uncertainty whether it will be
mainly be of the lighter (1 mile or more visibility) or denser
(1/4 mile or less visibility) variety, fairly widespread fog is
looking increasingly-likely both tonight-Thurs AM and Thurs
night-Fri AM.
- Rain potential keeps increasing especially in our south
Thurs-Thurs night:
Although not a "major soaker", rain chances and forecast amounts
keep creeping upward (and northward) within mainly our southern
coverage area (CWA).
- Friday the overall-nicest day of the next week:
Not only is Friday the only upcoming day through at least
Tuesday that features an entirely dry forecast, but it`s also
likely to feature the most sunshine of any day through then as
well.
- Saturday-Tues storm system still our overall-biggest
concern/issue:
Unfortunately we are still a few days away from gaining any
semblance of "higher confidence" in exactly how this system
plays out, but if anything latest trends point toward increasing
potential for at least spotty (and most likely weaker)
thunderstorm activity mainly Sat evening into Sunday daytime,
and PERHAPS a bit more snow accumulation potential mainly Sunday
evening into Monday night (including Christmas).
&&
.DISCUSSION...
Issued at 448 PM CST Wed Dec 20 2023
-- PRIMARY CHANGES IN THIS FORECAST "PACKAGE" VERSUS THE
PREVIOUS (EARLY-AM) one:
1) Although we don`t have any formal Advisories out at this
time, we are "hitting" fog a bit bit harder for tonight-Thurs
AM and also now Thurs night-Fri AM in our forecast products and
Hazardous Weather Outlook (HWOGID).
2) The Thurs-Thurs night system (all RAIN) continues to trend a
bit stronger and farther north, with at least a few hundredths
of an inch rain possible as far north as roughly the
Hastings/York areas, and parts of especially our KS zones
favored to pick up a good 0.10-0.20".
3) The coverage of slight thunderstorm chances (embedded within
much higher chances for rain showers) for Sat evening-Sunday
daytime has expanded to now include nearly the entire CWA. In
theory, these should be non-severe storms based on the most
likely scenario.
Otherwise, there has actually been minimal change with the
overall timing and rain/snow chances (PoPs) with the holiday
system, as the first slight chances (20%) move in Saturday
afternoon, peak at widespread 70-90% Sat night into Sunday,
remain up in the solid 50-70% range Sun night into Mon, and then
taper off down into the 20-30% range Mon night-Tues.
-- PRIMARY FORECAST CHALLENGES/UNCERTAINTIES (including all
further discussion of longer-term periods Fri daytime-Wed):
1) Just how widespread/dense/impactful might fog be these
next couple of nights/morning? Fog is almost always a
notoriously fickle beast to pin down much before it "shows its
hand", and there are at least some cons against truly
widespread/dense fog development (probably more so for tonight
than Thurs night?) See short-term-specific paragraphs below for
more on this topic.
2) Do RAIN chances need to trend higher (and perhaps a bit
farther north yet) for the Thurs-Thurs night system? While
confidence is pretty high that the vast majority of truly
measurable rain potential will focus south of Interstate 80,
there are definite questions as to whether most of the rain
remains in our far southern (KS) zones or perhaps gets up closer
to Hwy 6/I-80 corridors. See short-term-specific paragraphs below
for more on this.
3) The "Big Holiday Weekend/Christmas System (various
thoughts/latest trends):
- To be up front, we are still a full two days away (Friday)
from at least the vast majority of the wintry side of this
storm making it into our official "winter forecast window"
when we start issuing more official potential totals, graphics
(including probabilistic) etc. Hopefully by then things look
little clearer than they do know, but compared to some bigger
storm systems that consistent more of one/coherent low
pressure system as it approaches the Central Plains, the fact
that this one will clearly feature a complex
interaction/merger of two initially-distinct waves likely
means (more than usual) that it might be at least Saturday
before the picture really starts becoming clearer.
- In the basic big picture:
If anything, the overall timing of this system has come into
decent agreement in the ECMWF/GFS model world, with the first
isolated/scattered rain showers perhaps breaking out mainly
Saturday afternoon, the vast majority of showers/embedded
thunderstorms occurring Sat night into Sun AM, the vast
majority of snow (MAYBE some mixed precip in the transition
zone?) occurring Sunday afternoon through Monday AM (west to
east transition), with a turnover to all-snow likely CWA-wide by
later Mon afternoon-night. At least for now, the vast majority
of snow appears to be departed by sunrise Tuesday, but
especially the ECMWF suggests the parent low could stall over
the Midwest, and perhaps drag another "lobe" of light snow
potential southward over us before departing for good (at least
for now though, our official forecast is precip-free by
Wednesday).
- Thunderstorm potential:
While at this Day 3-4 range it still looks like most/all storms
would be of the weakish variety, there does appear to be a bit
more potential than 24 hours ago of realizing at least
weak/modest elevated instability on the order of 200-500 J/kg.
In theory, a few cores with small hail probably cannot be ruled
out Sat evening-night. Of course, a "worse case scenario" would
be something surface-based and possibly severe trying to form
Sunday daytime, but as long as the main surface low track and
associated dry slot remain at least slightly to our south, then
this concern should be minimal. That being said, this bears
close watching as (for example) the severe storm event of
12-15-21 was not exactly on our "radar" at this point in time
either.
- Overall precipitation/snowfall trends:
Taking 12Z deterministic runs at face value, it`s clear that the
ECMWF is giving us more of a wintry impact than the GFS which
gives us almost no snow (its latest run fails to truly phase the
upper system together into one more powerful vort max). But
turning to the ECMWF ensemble world (almost always the best
approach this far out in time), it is worth noting:
1) Overall precipitation amounts (including melted snow) have
increased a bit, with now a 60-90% chance that nearly our entire
CWA sees at least 0.50" out of this.
2) Potential for at least a few inches of snow has increased as
well, with probs for at least 1" of snow now up to 50-70%
especially in our west half, and 30-50% probs for at least 3" in
this same area. If this system were closer in time and we were
forced to put more definitive snow totals toward it, this would
suggest a fairly wide coverage of 2-4", not a "major snow
storm", but certainly enough to cause nuisance travel issues.
3) Non-zero chance for mixed precip types in the rain/snow
transition zone: Although FAR from a certainty, latest ECMWF
hints at at least a little freezing rain/icing potential mainly
Sun night-Mon AM before a full transition to snow occurs.
Something to watch, but far too soon to put much stock in.
- Winds:
Although perhaps trending a touch stronger than 24 hours ago,
this system does still not look particularly windy (unless the
surface low intensifies further), with gusts more along the
lines of 30 MPH than say 50 MPH.
That`s more than enough for now on this system, especially with
any wintry-impacts still 4-5 days away and plentiful (at least
minor) changes in model data likely.
-- SHORTER TERM FORECAST DETAILS FOCUSED SOLELY ON THE NEXT 36
HOURS: (through late Thurs night/Fri AM):
- Current/recent weather scene as of 4 PM:
As was suspected as a possibility, the morning began with a
narrow ribbon of dense fog in our eastern zones. While this fog
dissipated by mid-late morning, extensive mid-high level clouds
have streamed overhead all day, resulting in cloudy/mostly
cloudy skies and holding temps down at least slightly below
expectations most areas (highs ranging from low-mid 40s
central/northeast to more upper 40s south and especially far
west). Winds have been light (mainly at/below 7 MPH), and
generally out of the east. In the mid-upper levels, water vapor
satellite and short term model data depict us under broad
southwesterly flow aloft, with our first disturbance of interest
gradually heading our way from the AZ/NM border area.
- This evening-overnight:
The paramount concern is how extensive and dense/impactful fog
will be. Taking models such as HRRR at face value, there would
be a good chance of widespread/dense fog across much of the CWA
tonight. While that cannot be ruled out especially in the very
light, mainly easterly/northerly wind regime. That being said,
the night will start with quite a bit of high cloud cover (which
will hamper cooling and perhaps fog development somewhat),
although there will likely be some breaks/thinning of high
clouds as well. SREF visibility probs are not as aggressive as
HRRR, showing more muted fog potential, and is one of the main
reasons it was decided to "punt" any possible formal Advisory to
later shifts. Nonetheless, potential for a fog-ridden Thurs AM
commute is there, and is covered in our HWO. Precip-wise, the
vast majority of the CWA will remain dry tonight. However, as
low clouds gradually thicken/saturate in southern zones, felt a
slight chance of drizzle was warranted before sunrise in our
extreme south-southeast (Osborne/Mitchell counties mainly). Low
temps tonight could easily vary by 10+ degrees given differences
in cloud cover/dewpoint levels, and are aimed from mid-upper 20s
northwest to mid-upper 30s far southeast.
- Thursday daytime-overnight:
The disturbance currently over the Desert SW will arrive into
our CWA by late in the day, and then depart eastward generally
along the NE/KS border overnight. This system has trended a bit
stronger/further north than 24 hours ago. Considering our
forecast was dry just 48 hours ago, this has been a change. In
short, PoPs have been increased (probably not enough?) with rain
chances spreading as far north as Highway 6 in the afternoon,
but with the highest chances 30-50% in KS zones during the
afternoon, then increasing more in the evening especially far
southeast. There is some uncertainty as to how far north the
north edge of rain will be, with higher-res models (such as
HRRR) keeping most rain in our KS zones, while latest ECMWF/GFS
bring at least a few hundredths of an inch up to at least the
I-80 corridor. Based on current trends, rain potential will
probably increase further in the next forecast package, but we
are not talking big amounts, with even our far south unlikely to
exceed 0.25" Turning to fog potential, this could honestly be a
a pretty big forecast headache. Not only could Thursday start
out with areas of fog (some dense), but following a likely lull
in fog coverage/intensity during the afternoon, places
especially just behind the departing area of rain could easily
"fog in" again Thurs evening-overnight in a continued moist low-
level/light wind regime. However, the light winds will be
turning more westerly/downslope with time, which would tend to
slowly scour fog out from west-to-east heading toward the first
part of Fri daytime. Plenty of uncertainty here. Temperature-
wise, nudged highs down a good 2-5 degrees for Thurs in
anticipating of widespread clouds/rain/fog being a factor, with
most areas aimed mid-upper 40s and any low 50s favored extreme
west/northwest. Like tonight, lows Thurs night will likely
exhibit a good 10+ degree gradient across our CWA, and have them
ranging from mainly upper 20s far west, to upper 30s/near 40 far
southeast.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 545 PM CST Wed Dec 20 2023
Significant Weather: IFR to LIFR VSBYs and CIGs becoming
increasingly likely for late tonight through at least Thu AM.
Tonight: Will start off VFR with SCT to BKN high clds...but
after about 03-04Z, several pieces of guidance have been fairly
consistent in developing and expanding fog across both
terminals, perhaps slightly earlier and more dense at EAR than
GRI. However, seems increasingly likely that BOTH terminals will
see VSBYs fall to around or less than half mile by 08-11Z, with
CIGs/VVs likely not any better at only 200-300ft. Winds will be
lgt and vrbl during this time. May very well need a Dense Fog
Advisory overnight. Confidence: CIGs/VSBYs - Med, Wind - high.
Thursday: IFR to LIFR VSBYs and CIGs seem probable to persist
through most, if not entire, AM...with latest RAP/HRRR blends
not showing any significant improvement (to MVFR or VFR VSBYs)
until 18-20Z. And even so, this will probably be a situation
where ground VSBYs improve, but CIGs still remain very low at
only 300-800ft. Winds will remain lgt at around 5kt, or less.
Assuming we never fully mix out of the stratus Thu aftn, then
overall patter would support another round of at least IFR
CIGs/VSBYs Thu eve into overnight.
Confidence: CIGs/VSBYs - Medium, Wind - high.

.SHORT TERM...(This evening through tonight)
Issued at 204 PM EST WED DEC 20 2023
Key Message:
-Lake effect cloudiness, but otherwise quiet through Thursday
morning.
RAP analysis shows a 1039 mb high pressure over far northwestern
Ontario but otherwise not many synoptic scale features in the Great
Lakes with mostly zonal flow aloft. 850mb temperatures are around -5
C, which is just cool enough for some low level overcast lake effect
cloudiness, but anticyclonic surface flow is keeping anything
notable from precipitating out of those clouds. As the high shifts
east, winds will veer more southeasterly than the current easterly
and northeasterly flow. Temperatures should fall to the dew point
Thursday morning in the low to mid 20s, and with not particularly
strong gradient winds, windshields might get a bit frosty prior to
the morning commute, which will be the biggest weather impact
through Thursday morning.
.LONG TERM...(Thursday through Wednesday)
Issued at 158 PM EST WED DEC 20 2023
Upper air pattern consists of a closed 500 mb low off the CA coast
with a ridge across the ern U.S. 12z Thu. A shortwave trough moves
into the upper Great Lakes on Fri. Troughing moves onto the west
coast and into the Rockies by 00z Sun. Did not make too many changes
to the going forecast.
In the extended, the GFS and ECMWF show a 500 mb trough in the
Rockies moving into the western high plains 12z Sun. This trough
moves into the plains 12z Mon and then slows down as it moves into
the central U.S. 12z Tue. The trough then moves into the Great Lakes
region 12z Wed. Model differences continue with this system as the
ECMWF is slower and the GFS is more progressive and further east
while the Canadian model is more towards the ECMWF for the evolution
of the system but even slower. This system still bears watching as
it could be strong, but right now the pcpn looks to start off as
rain before the colder air arrives later in the period and will have
to watch its track. Manual progs have this system further north than
previous forecasts. Confidence is still low as models have
different solutions.
Temperatures will stay above normal for this forecast period. The
possibility of a white Christmas is still hard to predict in a lot
of places. The places that have seen 3 to 6 inches of snow the past
several days might have enough to keep it until Christmas Day when
it melts in the north to northwest lake effect snow belts. However,
the places that have less than 3 inches of lake effect snow will
probably be able to melt this off as temperatures go above normal
through then and will see a brown Christmas. This would be in most
areas away from the lake effect snow belts and especially in the
southern U.P. Next chance of pcpn will be late on the 24th and into
the 26th and this would mostly be rain.
