For the 00Z TAFs, isold to sct showers and tstms over sern CO and
nern NM will track east this evening and could graze the western
and central OK Panhandle with a very small threat that KGUY could
be impacted. Have omitted mention of this weather element at this
time due to very low confidence. Will closely monitor radar trends
this evening. Otherwise, VFR conditions are anticipated at the
TAF sites through late Monday afternoon. Showers and thunderstorms
are then forecast to move southeast into the region after 00Z
Tuesday, which is just beyond this fcst cycle.

.PREV DISCUSSION... /Issued 346 PM CDT Sun Aug 5 2018/
DISCUSSION...
Storms are already popping up in New Mexico and Colorado. Storms
are expected to make it to the Oklahoma Panhandle between 7 and 9
PM tonight. The HRRR was tracking pops relatively well so went
with that guidance on pops for the night. Not much CAPE to work
with, but decent DCAPE exists, so could see wind gusts to 50 mph
out of a good storm.
Going into the beginning of the work week, a cold front gets close
to the area and brings chances for precip as it interacts with a
mid-level shortwave riding around the rim of the upper level high
pressure bubble. With 2500 J/kg of CAPE and 1000 J/kg of DCAPE,
which is up from yesterday`s models forecast, damaging winds and
hail up to quarters could be possible. PWATs are forecast around
1.5 in which is well above the 90th percentile and near the
maximum average. Thus storms could have localized flooding
concerns as well. Models today were stalling out the front
slightly further north than yesterday, placing it more in the
northern Texas Panhandle than in the mid to southern TX Panhandle.
Depending on where this boundary sets up and any left over outflow
boundaries, Tuesday could have some interesting chances for severe
weather as well. CAPE and DCAPE are forecast to be even more than
Monday, with good turning in the low layers. Also, shear increases
to near 25-30 kts. While Wednesday also has decent values for
severe weather, the atmosphere may be so worked over by then that
it may limit the storm potential. It is really going to be
dependent on boundaries and where storms have been. The early
part of the week definitely bears watching.
The end of the week is a little more tricky. Models begin to
diverge on solutions, but the area looks to be in northeast flow
aloft, which is generally drier for us. There have been cases in
the past where we did have storms with this flow pattern, but for
now have followed the downward trend of drying out the weekend.

642 PM CDT Sun Aug 5 2018
.SHORT TERM...(This evening through Monday)
Issued at 245 PM CDT Sun Aug 5 2018
Primary forecast focus is on severe/heavy rain threats through
Monday.
Quasizonal flow aloft was inferred from water vapor imagery early
this afternoon across the Upper MS Valley with several embedded
shortwaves in the flow. At the surface, a cold front was draped
across central MN southwestward.
The forecast remains quite challenging through the evening as models
have struggled over the past few days with convective trends in a weakly
forced environment. Overall, a bit less impressed by severe
potential through the evening. Weak mid-level height rises are
expected through late afternoon before a shortwave trough
approaches from the west by early evening. Convection crossing IA
during the morning could also impact ultimate convective evolution
although many of the CAMs struggled to capture the early morning
convection.
Recent runs of the RAP have backed off on instability a bit, with
pockets of 1000 to maybe 2000 J/kg of MLCAPE within a low-level
confluent axis ahead of the approaching front. With the exception
of across northern Wisconsin, deep layer shear remains fairly
modest through the afternoon (~30 kts) before somewhat stronger
mid-level flow overspreads the area from the southwest during the
evening. Isolated to scattered showers/storms are possible this
afternoon and early evening, including along outflow boundaries.
Confidence isn`t very high on the coverage or placement of storms,
especially with limited upper forcing. Despite the marginal shear
and somewhat lower instability, still could not rule out a few
strong to severe storms going into the evening.
As deeper forcing and low-level convergence/moisture transport
continue to increase through the evening and overnight ahead of an
upper wave, expect convective coverage to increase during the
late evening and overnight. With CAPE gradually eroding through
the evening, any severe threat still is expected to transition to
more of a heavy rain threat given a favorably deep, warm and moist
environment. The preferred area for heavy rainfall looks to be
south of I-90 overnight. 1 to 2 inches of rain is possible,
although with potentially locally higher amounts. With relatively
dry antecedent conditions, would not expect any widespread hydro
issues, but will have to watch for any localized high rainfall
totals.
The threat for any severe weather continues to appear low on Monday
with widespread clouds and rain likely keeping stronger instability
south of the area as the frontal boundary slips southward. Would
expect the stronger moisture transport to slide south and east with
the front. However, with shortwave energy continuing to cascade
through the flow, showers and storms will remain possible Monday
into Monday evening, likely decreasing in overall coverage through
the day.
.LONG TERM...(Monday night through Sunday)
Issued at 245 PM CDT Sun Aug 5 2018
Low precip chances may continue into Tuesday as another shortwave
digs across the area. Otherwise, an extended generally quiet period
of weather is expected during this time. Northwest flow aloft will
continue through late week with high pressure at the surface. A weak
surface boundary may slip into the area by Thursday with a low
chance for convection. Overall, rain chances are low through the
weekend. Upper ridging may build east into the area towards the
weekend with some models developing a closed low southeast of the
area. Generally seasonable temps in the 80s are expected through mid
and late week.
&&
.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 642 PM CDT Sun Aug 5 2018
Watching an area of mainly showers stretching from southeast SD
eastward along the MN/IA border. Near-term environment is not
conducive for thunderstorms so removed thunder mention from TAFs.
That said, periods of showers are likely and could see some
temporary reductions in visibility with heavier rates. An isolated
gust to around 25 kts is also possible. Thunder chances increase
overnight, but confidence not high given current observational
trends. Will amend for thunder as necessary. Rain looks to end by
mid-Monday morning with VFR conditions thereafter. Light southwest
wind will be the rule, eventually shifting to the northwest Monday
afternoon.

National Weather Service Bismarck ND
1006 PM CDT Sun Aug 5 2018
.UPDATE...
Issued at 1006 PM CDT Sun Aug 5 2018
Multicellular convection from northwestern ND into northeastern MT
appears to be associated with a slightly stronger impulse aloft
based on earlier surface pressure falls focused in that area, and
recent observed propagation is directed southeastward along a weak
weak low- and midlevel frontal zone that extends from near Sidney,
MT, to Beulah and Jamestown, ND, as of 02 UTC. Weak frontogenesis
near that frontal zone and modest mass field responses aloft with
the approaching weak shortwave trough impulse will likely aide in
the continued east-southeast propagation and maintenance of that
area of showers and a few thunderstorms through the night, so we
used this update cycle to modify PoPs in line with that thinking,
spreading 40-50 percent probabilities into central ND after 05
UTC. The 00 UTC Bismarck RAOB captured multiple weak inversion
layers aloft and midlevel lapse rates around 6.5 C/km, and recent
KBIS and KMBX WSR-88D VWP data shows 0-6-km bulk wind differences
only around 20 kt in further support of multicellular convection.
Given locally amalgamating cold pools and residual steep low-
level lapse rates, a few strong storms -- possibly with both gusty
winds and some hail -- could occur in west central ND the next 90
minutes, but the overall risk of strong storms overnight will be
minimized by the lack of stronger instability and weak shear. Note
too that the lack of an appreciable low-level jet will further
hinder any notable theta-e response, tempering instability, and
negating any discernible improvement in shear profiles, as well.
UPDATE Issued at 706 PM CDT Sun Aug 5 2018
Little in the way of change was made with this update other than
to accommodate recent observational trends. Scattered convection
is ongoing early this evening, but is loosely focused along and
slightly to the cool side of a weak frontal zone extending from
near Rugby to Minot and Crosby per trends in GOES-16 images that
have shown more agitated cumulus in that vicinity during the last
few hours. Background ascent is modest -- though perhaps is a bit
more notable in northeastern MT per surface pressure falls, which
is likely reflective of an approaching impulse that should tend to
maintain at least a low-end chance of precipitation overnight as
it moves eastward. Another weak impulse is moving into western SD.
This scenario justifies an increasingly broad-brush approach to
the PoP forecast further from the near-term when extrapolation of
observational trends is appropriate. Mid-level lapse rates are on
the order of 6 C/km over most of the area, and surface dewpoints
are generally in the lower to middle 50s F save for the southern
James River valley, limiting instability and potential strength of
any storms. Recent 0-6-km bulk wind differences from the KBIS VWP
are also on the order of 20 kt, further suggesting that any storms
will likely have limited intensity, although a belt of slightly
stronger flow with 0-6-km bulk wind differences on the order of 30
kt may exist along the Highway 200 corridor per RAP analyses, in
support of a low-end probability of stronger storms in that area.
&&
.SHORT TERM...(This evening through Monday)
Issued at 143 PM CDT Sun Aug 5 2018
Latest water vapor imagery indicates a weak shortwave trough
located over southern Alberta/Saskatchewan and a couple of
shortwaves ejecting east from Wyoming. The northern stream trough is
forecast to slowly sag south through Monday, somewhat merging in
time and space with the aforementioned shortwaves in Wyoming as
they shift east. In doing so, low level cooling per a surface to 850mb
cold front on the NAM/GFS will shift a cold front from north to
south overnight into Monday morning. This will result in cooler
air with highs in the 70s Monday as well as generate the chance
for showers/thunderstorms this afternoon through Monday. Difficult
to pinpoint exact areas, but it would appear the north, southwest
and far south central may be more prone to the highest chances
based on the above thinking. Severe weather is not expected at
this time. Lows tonight will mostly be in the 50s, with lower 60s
south central.
.LONG TERM...(Monday night through Sunday)
Issued at 143 PM CDT Sun Aug 5 2018
Large upper ridge across the west will expand north and east with time
and envelop the northern high plains Tuesday through Saturday.
This will result in dry, along with warm to hot conditions,as
highs will range from the upper 80s to lower/middle 90s during
this time period. Differences arise late next weekend, as the GFS
advertises a cold front moving through Sunday/Sunday night, while
the ECMWF is slower and keeps the region warm and dry through
Monday night.
&&
.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 1006 PM CDT Sun Aug 5 2018
VFR conditions will generally prevail through the 00 UTC TAF
cycle. However, scattered showers and a few thunderstorms will
move from northwest and west central ND late this evening into
the central parts of the state overnight. Radar trends could
necessitate amendments or adjustments with the 06 UTC TAFs to
reflect higher confidence in impacts at some terminals. Localized
sub-VFR conditions are possible with any storms. Otherwise, there
will remain a chance of showers and thunderstorms over southern
areas through Monday in association with a weak frontal passage.

1003 PM EDT Sun Aug 5 2018
.SYNOPSIS...
Hot and humid weather returns this week as high pressure becomes
centered off the East Coast. Scattered showers and
thunderstorms are possible Tuesday through Thursday, with a
possible return of showers and thunderstorms next weekend.
&&
.NEAR TERM /THROUGH MONDAY/...
10pm update...
Minor changes as the previous forecast remains on track.
Fog is still possible this evening, especially across the
northern Connecticut River Valley as both the HRRR and the
NARRE show high probabilities of visibility less than 4 miles.
Guidance is not as consistent with fog on Nantucket this
evening, however given the latest dewpoints, light onshore
winds, and a weak inversion aloft, fog still remains possible.
Previous discussion...
Forecast patchy dense fog across the Mid-CT River Valley and other
interior locations, possibly Nantucket as well. With light winds
and clear conditions, radiational cooling proceeding overnight.
Dewpoints remain high as most of S New England remains saturated
from recent rains. A blend of fogger tools and near-term high-
res guidance, likely pockets of interior dense fog, thinking the
shallow ground type. Meanwhile off the coast of Nantucket, a low
cloud / fog deck lingers. Winds have already dropped as has the
dewpoint depression. Will be evaluating this area closely with
respect to any low cloud / fog expansion over the island. The
bulk of the guidance surprisingly keeps it quiet and dry with
milder conditions. Looking at lows around the mid to upper 60s
across the interior, some lower spots, while around 70 over the
S-coast and urban centers.
&&
.SHORT TERM /MONDAY NIGHT/...
* Heat Advisories being issued for most of SNE *
Main concern is return of heat and humidity Monday. 12z models
and ensembles continue to point toward highs in low to mid 90s
across much of interior, and with dewpoints around 70, heat
index values peak between 95 and 100 degrees. We are issuing
Heat Advisories for all but Cape Cod, Islands, and Newport and
Bristol Counties in RI where onshore winds will keep it slightly
cooler and heat index values should peak closer to 90.
Advisories will continue into Tuesday based upon criteria of two
consecutive days with a heat index of 95 degrees or higher.
Otherwise expect some diurnal clouds once again but dry weather
with upper ridge in place. May have short-lived sea breeze along
E MA coast midday Monday before increasing S/SW flow gets
underway as high pressure settles offshore.
SW flow Monday night means a warm and humid night, as well as
low clouds/fog near South Coast, Cape Cod, and Islands.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
*/ Highlights...
- Hot and humid conditions for Tuesday, possibly Wednesday
- Shower / thunderstorm activity Wednesday night - Thursday
- Warm and dry late week
- Possible return of showers / thunderstorms for the weekend
*/ Overview...
Warm days, mild nights. General H5 trof pattern maintained by up-
stream N-Central Pacific to SW CONUS H5 ridge-trof-ridge pattern
amplification. Against the SE CONUS Atlantic tropical ridge, W/SW
continental-tropical airmass maintains, continuously pumping warm,
moist air N/E towards the St. Lawrence valley up against a series of
individual disturbances dipping S through aforementioned trof. While
absent anomalous precipitable waters / pure tropical air cut-off by
the SE CONUS ridge, still looking at shower / thunderstorm chances
with an excessive rainfall risk by midweek into the weekend along
frontal boundaries becoming diffuse up against the ridge / higher
heights. That being said, drier air seemingly ushers in behind any
frontal boundaries, perhaps some relief if trof disturbances can
really dig in against the ridge, the boundary layer becoming well
mixed, otherwise humidity hangs around with near to warmer-than
average conditions, any nudge upon which should yield showers and
thunderstorms, possibly again this weekend.
*/ Targets of Opportunity...
Tuesday will be hot and humid with heat indices at or above 100. H85
+17-18C air well-mixed yielding highs in the upper 80s to low 90s.
Can`t rule out some locations reporting highs around the mid 90s. SW
flow which climatologically given the interior fetch yields warmer
temperatures in and around the Merrimack River Valley and Boston-
metro given the urban environment. Likely here we`ll see highs up
around the mid 90s with heat indices above 100 as dewpoints will be
near 70. A slight change to the airmass Wednesday, however clouds
from upstream convection may limit greater daytime heating. We`ll
have to watch closely as to whether we`ll see a repeat of Tuesday
requiring a continuation of heat-related headlines.
Watch closely the Wednesday night into Thursday timeframe. As noted
by the prior forecaster, favorable jet dynamics N/W above decent low-
level forcing and instability. Likely shower / thunderstorm activity
upstream over NY / PA, have to watch evolution into NW S New England
towards evening, then going into Thursday with frontal passage. Can
not rule out heavy rain / flood impacts especially N/W, the region
well-saturated from earlier rains, streamflows well-above average,
urban issues always anticipated if you can throw down a quick 1-2".
Possibly watch as to whether any moisture is usurped from the sub-
tropical axis off the Mid-Atlantic.

.DISCUSSION...
Evening Update...
Showers and storms developed late this afternoon and this evening,
mainly along a southeastward-moving outflow boundary pushed out by
earlier convection. There have been nearly zero reports from this,
but radar indicated very heavy rainfall under the strongest cores.
Would not be surprised to learn that those locations may have
received one to over two inches of rainfall in brief periods of
time. There is some concern of possibly some localized flooding
along the gravel roads leading to recreation areas along Fort Peck
Lake, so we issued a Flood Advisory until 10 PM this evening.
Expectations are that the convective nature of these storms will
rapidly dissipate over the next hour or two, then just a few
showers will remain to push across northeast Montana.
Regarding the overall forecast, went with the RAP model for pops,
which handled the developing line of precipitation pretty well.
Minimal changes were made to the temperatures and winds with this
update. Hickford
Previous Discussion...
Scattered showers and isolated thunderstorms have broken out yet
again for the region and will continue to expand to cover many NE
Montana locations through the rest of this afternoon and evening.
Models continue to show spotty coverage, so I tried to show this
the best that I could following the best model consensus coverage
I could find, allowing for some blending due to general small
uncertainties.
By Monday most of the shower and thunderstorm activity will be
confined to areas near and south of I-94 while skies clear nicely
across our west.
Monday night, our entire region clear out of precipitation, and
the western states ridge of high pressure re-establishes itself.
Expect hot temperatures and dry humidities to prevail Wednesday
through Saturday. Fire weather concerns could easily be heightened
and will need to be closely watched if the wind forecast
increases.

.SYNOPSIS...
Smoke from California wildfires will reduce air quality across
the region in the early part of the week. Above seasonal
temperatures are likely to bring impacts from excessive heat
through Wednesday. Otherwise dry conditions will prevail. &&
.UPDATE...Visible satellite loops prior to sunset showed smoke
covering most of the forecast area from Clark County northward. The
00Z HRRR Smoke model initialized quite well and indicates the smoke
will begin to lift to the northeast this evening, but additional
smoke over central Nevada is then forecast to advect southward late
tonight and Monday morning. The most dense smoke will be over
Inyo/Esmeralda and central Nye counties through Monday. We should
see a decrease in smoke concentrations over Clark County Monday.
This trend is covered in the going WX grids and no immediate changes
are needed.
&&
.SHORT TERM...Tonight through Tuesday Night.
A vast portion of the CWA is seeing the effects from smoke today.
In most cases, the smoke is reducing visibility slightly, but
affecting air quality as well. It still appears that the southern
part of our area (San Bernardino County, southern Clark County)
may see a small bit of relief later this afternoon as southwest
flow kicks and and pushes the smoke back north and east. No such
luck for the rest of the area. However, visibilities are expected
to improve some as afternoon heating and low-level mixing occurs.
The HRRR-Smoke model is still showing another push of high smoke
concentrations down through Inyo County tonight. I added reduced
visibility down to 1 mile in both the public forecast and BIH TAF
given these concentrations. Conditions will be similar to what we
saw yesterday and the day before in that area. Likewise, this
same process would again spread lower concentrations of smoke over
the rest of the area. Thus, we are in for another smoky morning
on Monday.
The other thing we will deal with is the upcoming excessive heat.
Models have remained consistent in showing strong high pressure
to build over the region leading to excessively hot temperatures
that are forecast to last through mid week. Have gone ahead and
upgraded the Excessive Heat Watch to a Warning for all areas
staring Monday and continuing through Wednesday with Tuesday and
Wednesday likely being the hottest days.
.LONG TERM...Wednesday through Saturday.
Hot weather will continue Wednesday with a large high pressure ridge
situated over Central Nevada, however, heat should begin to moderate
in the long range period. This will be especially true for our
southern zones as increasing surface moisture moves into the region.
The impetus for the increasing moisture will be a likely hurricane
moving northward along the west coast of Mexico, inducing a modest
gulf surge up the Colorado River Valley on Wednesday. This surge is
likely to be fairly shallow, but will contribute to a few degrees of
cooling south of I-15 starting Wednesday. A few isolated showers
and storms may form during the afternoon and evening as well across
the higher terrain of our southern zones. High pressure will remain
dominant across much of the Interior West through the weekend, but
increasing low grade monsoonal moisture will result in gradual
cooling and modest increases in thunderstorm potential as we head
into the late week timeframe, particularly along and south of I-15.
Further north, delayed moisture arrival will mean prolonged warm
temperatures through the end of the week.
The Excessive Heat Warning extending through Wednesday looks good,
though it may need to be extended into the Thursday-Friday period
for areas north of I-15 where intense heat is likely to linger.
&&
.AVIATION...For McCarran...Expect south to southwest winds to remain
at or above 10 knots through the night. Variable winds generally
less than 8 knots can be expected Monday with decreasing smoke
concentration in the terminal area.
For the rest of southern Nevada, northwest Arizona and southeast
California...Smoke concentrations near the surface will continue
through Monday across Inyo County and south central Nevada, but will
also impact eastern San Bernardino County, southern Nevada, and
northwest Arizona. It appears smoke will be dense enough to cause
visibility restrictions primarily at the Bishop terminal area.
Variable winds will generally remain below 15 knots across the
region except near Barstow where gusty west winds to 25 knots can
be expected through early Monday morning.
