Issued at 217 PM CST Tue Jan 7 2025
Snowfall continues today for the Oklahoma Panhandle and the
northern Texas Panhandle. We could see an expansion of the snow
bands further south later tonight. Odds of accumulations over 1
inch are very low.
Additional systems through the week will provide more chances for
light snowfall. Cool, below normal temperatures will continue
through most of the coming days this week.
&&
.SHORT TERM ...
(This evening through Wednesday night)
Issued at 217 PM CST Tue Jan 7 2025
Weak frontogenesis and sufficient moisture have allowed snowfall
to transpire in our northern zones this morning and we are seeing
a continuation this afternoon as the snow band shifts steadily to
the east. Despite being in the left entrance region of the 300 mb
jet, some modest upslope flow could be lending aid to the
progression of the snowfall. Snowfall rates are returning lower
than originally anticipated, so accumulations are not expected to
be impactful for any area during the duration of this system.
Tonight, the surface high to our northeast should move further
south across central Oklahoma. Forecasted midlevel theta-E
suggest that moisture will travel southward across the Texas
Panhandle. Additional snow flurries and perhaps some light
snowfall may accompany this transition, especially if upslope
flow could see enhancement through the Canadian River Valley
despite the light surface winds. One caveat that the HRRR has
introduced is some dry air entrainment through the Texas Panhandle
as the surface high expands. The timing of this surface feature
may severely limit the amount of snow locations near the I-40
corridor could see. In either scenario, snow accumulation should
not meet or exceed one inch.
Tomorrow, snowfall should cease by 7 AM. Cloud coverage will
slowly disperse, and high temperatures should rise to the upper
30`s and lower 40`s across the combined Panhandles.

.LONG TERM ...
(Thursday through next Monday)
Issued at 217 PM CST Tue Jan 7 2025
Trends in the synoptic overview continue to change in the long
term period. Currently, mid to long range deterministic models
show the H500 closed low over NW Mexico breaking down into an open
wave as the next upper trough from Canada ejects southward and
mixes with the preexisting area of low pressure. Afterwards, the
system`s progression still shows some uncertainties amongst the
guidance. Though the general consensus dictates that there should
be two different low pressure centers as the wave slowly converges
and transitions eastward.
Thursday, we will see the two different systems begin to combine.
The low to the south should have strong vorticity collide with
ample moisture for areas around northwest Texas and southwest
Oklahoma. Precipitation should begin to generate in those
locations Thursday morning and advect into the southeastern Texas
Panhandle as the morning carries on. The second trough should
enter our CWA in the afternoon and winds at the surface will turn
from the north. This front should also aid in producing snowfall,
but forecasted accumulations appear light and unimpactful. (<0.5")
While a chances for snowfall proceed to spread across much of the
CWA, chances for accumulations at or above 1 inch are now quite
low.
Once that system moves through, we enter more of a quiet pattern
for the weekend. However, with another potential cold front
Saturday night into Sunday, the GFS still shows snowfall trailing
with it. Overall trends are backing off though, so NBM POPs have decreased
for that time frame.

(00Z TAFS)
Issued at 442 PM CST Tue Jan 7 2025
A weather system continues to impact the panhandles this evening
into the overnight hours. This system is currently producing a low
clouds deck of MVFR levels at KGUY. This cloud deck is expected to
spread to the south through the evening impacting KDHT then KAMA.
There is a moderate chance that this cloud deck may fall to IFR
levels during the overnight hours. There is also a low to moderate
chance that this cloud deck will spawn a few snow flurries as was
the case earlier at KGUY. Currently the chances of this occurring
were high enough to be reflected in the KDHT TAF but not the KAMA
TAF. Any snowfall would be light and amount to a dusting to a non
accumulating couple tenths of an inch at the airfields. Once this
system pushes to the south it will cause rapidly improving
conditions with clear skies during the mid morning hours of
Wednesday.

.UPDATE...
Issued at 857 PM CST Tue Jan 7 2025
Much of the low level stratus in western ND has dissipated,
although persists in the far northwest. A narrow ribbon is also
passing through parts of the southwest into the south central. A
second ribbon of low level stratus also remains over the James
River Valley, though has decreased in areal coverage since the
previous update and is slowly progressing eastward. Further
adjusted sky cover based on the latest trends, but all in all,
the forecast remains on track.
UPDATE Issued at 551 PM CST Tue Jan 7 2025
Low level stratus is present over much of western ND,
especially the northwest, with another strip over south central
through northeastern parts of the state. Adjusted sky cover
based on the latest trends. Otherwise, the forecast remains on
track.
&&
.DISCUSSION...
Issued at 131 PM CST Tue Jan 7 2025
Latest satellite imagery shows low clouds continue to diminish
across the forecast area this afternoon. Surface high pressure
is centered over the Northern Plains, and tracking to the
southeast. Expect low clouds to continue to dissipate through
the afternoon. Based on the RAP low level RH, the clouds from
just west of the Missouri River up to eastern portions of Lake
Sakakawea and northeast towards the Turtle Mountains may linger
the longest, with clouds clearing faster in the west and over
the southeast.
For tonight, the first concern will be temperatures. As surface
high pressure slides southeast, we see warm advection return
from west to east tonight. We expect temperatures tonight to be
generally in the single digits above or below zero, and this
will partially depend on how warm it gets today, but in
general, expect temperatures more in the below zero range
central and above zero west. Temperatures are also expected to
climb overnight, especially west, but eventually over central ND
as well. Current NBM hourly temperatures at 6 AM Wednesday are
ranging from the single digits above zero central, to the teens
west.
Upper level ridging is expected to traverse the forecast area
Wednesday with quiet weather expected for the most part.
However, by Wednesday afternoon, a shortwave tracking across the
northern Rockies will approach western ND. This wave, is
expected to produce a band of precipitation that tracks
southeast across the forecast area late Wednesday through
Thursday morning, and lingering over the James River Valley
area Thursday afternoon. The qpf amounts have increased a bit
and now amounts from 5 to 15 hundredths of an inch liquid are
now forecast across the CWA. Snow amounts are expected to be
light with NBM snow totals ranging from a half inch to an inch
and a half. NBM Ensemble probabilities of 24 hour amounts of an
inch or more are in the low to medium range, with medium
chances of 40 to 70% centered over the west central into the
southwest. These probabilities also vary, from the far west
central and southwest, to pretty much all areas south and west
of the Missouri River. Thus uncertainty remains pretty high at
this time. Probabilities drop pretty quickly to the north and
east. Probabilities of 2 inches or more are low over the west
central and southwest, to very low (<10%) elsewhere. There are
some winds with this system on Thursday. For the most part, the
winds look to be on the back end and after the precipitation.
The blowing snow model is depicting mainly patchy blowing snow
with this system. There does looks to be a period of stronger
winds Thursday afternoon. Later shifts may need to monitor for
possible wind advisory criteria winds. We have some pretty steep
lapse rates over us, so if we could mix out, it might be a
pretty windy afternoon.
Another concern is the precipitation type. Bufkit model
soundings are showing a pretty quick transition of the warm
layer aloft as precipitation begins. However, short term models
going out that far are all showing at least some freezing rain.
HREF is also showing some light freezing rain. The NBM
probabilities of freezing rain are quite low, but they have been
on the low side with our past few freezing rain events. Pretty
much went with the NBM precip types, which produced some light
ice accums. As for the placement, I don`t think there is one
favored location at this time (perhaps as we get closer to the
event) but I`s say on the leading edge and the trailing edge of
precip, there is a chance of some light freezing rain/freezing
drizzle. The band of precipitation (based on mesoscale models)
is in general, pretty narrow. Along the leading edge, before the
column saturates, think there is the potential for some
freezing rain. Then as the system exits, some light freezing
rain/freezing drizzle may be possible at times as we lose some
ice aloft.
Behind the system we cool down, especially in the north central
with highs back into the teens. Meanwhile the southwest
continues to see temperatures into the lower 30s.
The next system tracks over the area Saturday into Sunday. This
system looks to be a combo system where an Alberta clipper and a
pacific wave meet over the Northern Plains, with a Hudson Bay
Kicker. The combo wave will bring a swath of precipitation to
the forecast area Saturday into Sunday. A wintry mix can`t be
completely ruled out on the leading edge of this system as well.
Whether the waves combine together, or one tracks quickly on
the heels of the other, the Hudson Bay Low will follow, bringing
much colder air into the Region late in the weekend and into
early next week. This system also looks to bring mainly light
snow amounts, but slightly higher than the mid-week system,
with medium to high chances (30 to 80%) for an inch or more of
snow, and low to medium chances (10 to 60%) for 2 inches or
more. Favored areas look to be in the west and north, but there
is still a lot of uncertainty with this system as well.

*update at 0257Z*
IFR stratus did wind up impacting KXWA for a few hours, though
looks to clear off imminently. Overall, most of western ND has
seen low level stratus clear off for now other than in the far
northwest and a narrow ribbon transitioning from the southwest
to the south central. A second narrow ribbon persists over the
James River Valley, though continues to gradually progress
eastward while narrowing in areal coverage.
Original discussion:
A relatively narrow strip of MVFR stratus is present over south
central through northeastern ND. This appears to be steadily
moving eastward, though a bit uncertain if it will stall or
redevelop tonight. Especially over the James River Valley,
including the KJMS terminal. Additional low level stratus is
entering western ND as well. Most of it on the North Dakota side
of the border is low VFR, though there may be pockets of MVFR
stratus as well. There are some observations suggesting IFR
pockets on the Montana side, however, that may cross into
western ND over the next few hours. Maintained VFR ceilings for
the KDIK and KXWA TAFs, though wouldn`t be surprised if MVFR/IFR
ceilings crept in at least temporarily this evening.

.DISCUSSION...
Issued at 213 PM CST Tue Jan 7 2025
An upper level shortwave continues to make its way southward into
Iowa as seen by RAP 500 mb heights. With a lack of a good moisture
source seen in the lower levels, we are mainly seeing mid to upper
level cloudiness associated with this feature. A few flurries have
been reported this afternoon across portions of southeastern South
Dakota into the Siouxland area around KSHL and KSUX. However, with
the very dry airmass in place at around 850 mb and below as seen
from BUFKIT soundings, not expecting much of this to reach the
ground across portions of western and central Iowa as the shortwave
continues to move southeastward tonight. Lows tonight will reach the
single digits as cold air advection at 850 mb continues to filter in
with the northwest flow. Subzero wind chills will be seen throughout
the night and into the morning on Wednesday as the shortwave and
associated cloud cover depart. A ridge will briefly build and make
its way into Iowa by Wednesday afternoon/evening which will lead to
fairly benign weather. High temperatures for Wednesday will be in
the low 20s areawide, but wind chills will still be cold with values
anywhere from 5-10F. Those venturing outdoors during these cold
periods should take precautions and dress warm.
The weak ridging on Wednesday will be short-lived as another
shortwave will drop down from Canada late Wednesday night. Warm air
advection will also return for Thursday as the high pressure area
across the Central Plains moves away from the area. The shortwave
feature will drag along a cold front with lift overspreading the
area by early Thursday morning. The front enters northwest Iowa by
Thursday afternoon, and this will be the focal point for precip
formation in the afternoon and evening hours, first across the north
and then moving eastward. The NBM has struggled somewhat in
capturing these PoP chances along the front, so have blended in
short term model guidance with NBM to help account for this and have
collaborated with neighboring offices. Precipitation will be in the
form of snow given the cold temperatures seen in the lower
atmosphere from soundings, but accumulations should be minimal, with
only a tenth of an inch at best across the far north. GEFS/GEPS/EC
output from the LREF shows around 70-80% of members having less than
a tenth of an inch across the majority of area.
The front will exit the state Friday morning with any lingering
snowfall ending. Northwest flow makes a return as the trough departs
the area, with the next system approaching the area early Sunday
morning. At this time, the current track of the low is quite
variable as hinted in the previous discussion. The ECMWF ensemble
continues to have the low pressure on a more northerly track in
southern MN/northern IA with little QPF, while GFS ensembles still
have a track that is more southerly with very little QPF. Current
NBM output has started to place ~20% PoPs across the majority of
northern Iowa at this time. Regardless of the track, will need to
watch this system to see if any intensification and better model
consensus occurs, so stay tuned to the forecast for further
updates.

.DISCUSSION...
A strong shortwave upper level trough is digging southward into
southern California this morning, directing winds aloft to the
northeast as they move cyclonically around the system. The
combination of the atmospheric pressure gradient and the
relatively sparse environment in eastern California and western
Nevada will allow strong wind gusts to develop, especially along
the crests of the Sierra Nevada and in the Mojave Desert.
Ensemble guidance from the National Blend of Models gives a
70-90% chance for wind gusts to exceed 60 miles per hour at the
highest elevations along the central Sierra crest in Madera and
Mono counties, with high-resolution deterministic values from
the 12Z run of the HRRR expressing maximum wind gusts in this
area near 85 miles per hour later this afternoon. As the
aforementioned system progresses southward into northwest Mexico
later this evening, the focus of these strong winds will move
to the Mojave Desert, where NBM guidance expresses a 40-60%
chance for wind gusts greater than 50 miles per hour for the
communities of Edwards AFB and Johannesburg and a 60-90% chance
for the town of Mojave and Indian Wells Canyon. Hazardous
crosswinds are expected along California Highways 14 and 58,
with the potential for a reduction in visibility due to blowing
dust. Winds will gradually diminish across the region through
Wednesday morning as the upper level system tracks into Baja
California.
While this area of low pressure aloft moves out of the region,
a high pressure ridge will progressively slide eastward off the
coast of California. Upper level flow is expected to continue
from the northeast as a result, setting up a slight cooling
trend that will bring a chance for freezing temperatures in the
San Joaquin Valley Thursday morning; the rural areas of Kern
County, including but not limited to, the communities of
Buttonwillow, Shafter, and Wasco have a 50-75% probability for
morning lows less than 32 degrees. However, these cooler
temperatures are anticipated to be short-lived as the
aforementioned ridge builds in over central California Friday,
bringing morning lows in the valley areas back near season
averages, and warming afternoon highs around ten degrees above
normal. The following are probabilities for maximum temperatures
greater than 60 degrees for various locations of the San
Joaquin Valley.
Tuesday Wednesday Thursday Friday Saturday
Bakersfield 4% 35% 65% 100% 4%
Coalinga 70% 70% 90% 100% 80%
Fresno 35% 20% 30% 95% 0%
Hanford 35% 45% 50% 96% 10%
Madera 75% 10% 20% 90% 2%
Merced 90% 20% 50% 96% 20%
Visalia 10% 10% 30% 95% 0%
An additional cooling trend will set up for the area over the
weekend and into next week as a longwave upper level trough
develops, shifting the upper level flow across central
California from the north to northwest. Maximum temperatures are
anticipated to be near normal for this time of year, with
minimum temperatures three to five degrees cooler than average,
especially in the more rural areas of the San Joaquin Valley.
However, cluster analysis points towards a shortwave trough
cutting off from the main longwave system Tuesday which has the
potential to result in another inside slider system. Early
indications from the NBM suggest a 40-60% probability for
maximum wind gusts to exceed 40 miles per hour in the Mojave
Desert Slopes and crests of the Sierra Nevada next Tuesday.

...New UPDATE...
.UPDATE...
Issued at 841 PM CST Tue Jan 7 2025
Overall, current forecast is in good shape. The main question for
the overnight period is the effect of the winds and cirrus clouds
on the low temperature forecast. If the cirrus thickens and hangs
around the entire night, temperatures in the Freeze Warning area
could stay just above freezing. Winds may be a complicating factor
just south of Lake Pontchartrain if they don`t decouple. The fact
that Belle Chasse has already dropped to 6 mph means we could see
lighter winds overnight away from the immediate lakefront. To
reiterate the short term discussion from this afternoon, it`s
realized that not everyone in the Freeze Warning will fall below
32 degrees. There can be as much as 5 to 10 degrees difference in
overnight low temperatures within one county or parish on clear
nights with light winds.
At this point, we will keep the Freeze Warning and Cold Weather
Advisory for overnight in place.
&&
.SHORT TERM...
(This evening through Wednesday night)
Issued at 353 PM CST Tue Jan 7 2025
Zonal flow continues over the region with only a little moderation
in temperatures through the short term period. Daytime highs on
Wednesday will be slightly warmer with most warming into the 50s,
but still well below average for this time of year. As for
overnight tonight, went ahead and upgraded the Freeze Watch to a
Freeze Warning for the southshore with the understanding that NOT
everyone will reach freezing, but some of the cooler suburbs and
outside urban heat island will likely drop below freezing for a
time around dawn. Kept the CWY for the northshore, southwest
Mississippi and the MS Gulf Coast for wind chill values as low as
the upper teens in the coolest locations and around 20-25 for the
northshore and Baton Rouge.
Going into Wednesday night and Thursday morning this should be the
coolest as winds try to go near calm across the region. Depending
on increasing clouds, radiational cooling will help drop many
locations below freezing. Additional cold weather headlines are
possible, but with the cloudiness or the low confidence in sky
forecast, decided to not issue at this juncture. (Frye)
&&
.LONG TERM...
(Thursday through Monday night)
Issued at 353 PM CST Tue Jan 7 2025
By Thursday the quasi zonal flow transitions to a more active
southwest flow aloft. At the same time a surface low will evolve
near the mouth of the Rio Grande as an upper level H5 trough
amplifies over the high plains. This will help numerous showers
develop ahead of the low, especially along the warm front with
isentropic help. As the low continues to develop and moves over
our CWFA a (frontogenetic) band of heavy rainfall will likely
develop somewhere over southeast Louisiana or south Mississippi.
That said, models have pushed back the onset and best heavy rain
potential to around sunrise through noon or so...and the band of
heaviest convection look to be a bit more transient. PWs range
from 1.5" across the northern tier to around 1.8 along the
immediate coast so rates will be fairly high on the
southshore...which is the primary location of concern. The dry
slot looks to come over the region from 18-21z on Friday, which
again will limit the hydro potential slightly. WPC went with a
marginal ERO for most of the CWFA respectively and at this point
cannot argue with this delineation.
The upper trough digs and pushes eastward through our region
Friday and into Saturday. Temperatures from this point will be the
primary focus through the end of the long term period with the
next potential for rainfall coming in just beyond the scope of the
forecast (next Tuesday). Although heights and thicknesses evolve
to more of a zonal flow, which should allow for moderation,
however, temperatures through the long term will still remain
below average with lower thicknesses and heights residing over the
area. (Frye)

Generally VFR conditions across the terminals through the period.
Mainly just some cirrus clouds, particularly at the southern
terminals. Wouldn`t be a total shock to see a few stratocumulus
clouds downwind of Lake Pontchartrain briefly in the morning, as
HRRR forecast soundings indicate there might be enough moisture
around 950 mb for a thin layer of clouds. So, MVFR ceilings can`t
be entirely ruled out at KNEW and KMSY on Wednesday morning.

Issued at 325 PM CST Tue Jan 7 2025
High pressure tries to move into the region from the northwest,
which should relax surface pressure gradients a bit. However,
there will be enough to allow for moderate winds and seas to
continue. For this placed most of the local waters outside of the
tidal lakes in Cautionary Headlines for winds over 15kt at times.
The best potential will be beyond 20nm. Going into late week a
surface low pressure will develop from a trough east of the Rio
Grande Valley. This low will track north and east toward our
region restrengthening the low level pressure gradient and once
again there will be a need for Small Craft Advisories late in the
day Thursday through late Friday before pressure gradient breaks
down once again. (Frye)
