Area Forecast Discussion
National Weather Service Cheyenne WY
1052 PM MST Tue Feb 21 2023
.SHORT TERM...(This evening through Thursday)
Issued at 400 PM MST Tue Feb 21 2023
The anticipated major winter storm for portions of our area is
beginning across portions of Southeast Wyoming and the Nebraska
panhandle. While the forecast is largely on track, there have been a
few minor but important changes with this update. The highlights are
as follows:
* A very high impact event is still on track for northern Carbon
county, with snowfall accumulation in the 12 to 20 inch range and
blizzard conditions expected to begin tonight.
* A northward shift in recent model guidance has resulted in
slightly reduced forecast snow totals for those along and south of
a Laramie to Alliance line. Impactful snow is still expected, but
totals have decreased slightly.
* Dangerously cold wind chills are expected behind this arctic
front. Apparent temperatures between -25 and -40F are likely for
the majority of the forecast area Wednesday night into Thursday
morning. A Wind Chill Watch has been issued.
Currently, our area is under moist WSW flow aloft ahead of a potent
trough rapidly digging into the west coast at this hour. The
downstream branch of the trough is leading towards falling pressures
over southwest Wyoming and northeast Utah as the lower atmospheric
low pressure center starts to develop. Meanwhile at the surface, the
arctic high is pushing southward. The combination of those two
effects is rapidly reducing (and eventually reversing) the cross-
barrier pressure gradient. Thus, the strong westerly winds have
waned this afternoon after a very windy morning. Can't rule out a
quick burst of winds right before the front pushes through, but
after that winds are expected to reverse. The cold front has already
pushed into our northern counties, with Douglas reporting north
winds, a temperature of 32, and light snow. Bitter cold temperatures
are lagging behind the initial wind shift a little bit (still
appears to be north of Rapid City at this time), but arctic air is
still expected to reach the Colorado border by shortly after
midnight. Snow has already begin in Carbon county per radar and
webcams, but the blizzard conditions will likely hold off for a few
more hours until the reverse gradients set up and initiate
northeasterly winds. Further east, some light echos are showing up
over the North Platte River Valley, with Scottsbluff reporting light
rain for the last two hours or so. Some areas getting wet may see a
flash freeze and icy conditions when the front passes through this
evening and rain flips to snow quickly.
Over the next 12 hours, the storm is expected to evolve rapidly. The
upper level low will dig deep into the southwest this evening, and
support low level cyclogenesis over central Utah. This progression
has been the main source of the forecast uncertainty with this
update. The 12z suite of hires models came in with a significant
northward shift in precipitation, cutting down on totals for
southern and eastern portions of the forecast area, while the global
models still held strong with the higher end of the forecast.
Digging into the details producing this difference, it could be seen
that this change resulted from the positioning and strength of the
low pressure center. The RAP model earlier was showing the 700-mb
low positioned over SW Wyoming at 12z tomorrow, while the GFS was
holding consistent with this feature over central Utah. The ECMWF
and NAM were somewhere in between. This RAP solution then had a less
amplified low, leading to southwesterly flow in the 600 to 800-mb
level, rather than SSE flow. Such wind direction would be less
effective isentropic lift and theta-e advection working into the I-
80 corridor near and east of Laramie. This presents a compelling
failure mode that would result in the lower end of totals being
realized in southern and eastern portions of the area (but would NOT
affect totals in areas such as Rawlins, Wheatland, and Chadron). To
account for these trends, amounts were trimmed slightly on the
southern fringe. Did drop totals more significantly in Laramie,
because a lack of dynamic lift aloft would result in much less snow,
since orographics are very unfavorable there. Still looking at the
low end of warning criteria for these zones, but a further northward
shift could put that in jeopardy. However, 18z hires model trends
have ended this northward shift, and even wobbled slightly further
south, putting our official forecast that split the difference
between the 12z global models and hires models in a good position.
Further north and west, the forecast is still looking largely on
track. Northern Carbon county from Elk Mountain to Rawlins still
looks like it will see the most significant impacts. Model QPF means
remain around 0.8 to 1.2, which supports the current forecast of 12-
20 inches of snow with locally higher amounts possible. Strong winds
developing under impressive reverse pressure gradients are likely to
produce gusty winds of 40 to 50 mph and blizzard conditions in this
area. Significant blowing/drifting snow will compound the impacts.
The heavy snowfall rates will be partially attributed to the strong
frontogenesis predicted in this area, as the low-level front gets
hung up on the mountains to the south. Models remain consistent in
keeping this forcing over the area, which would lead to heavy banded
snowfall. There is some variability in the exact location of the
heavy band, which will likely be the difference between the lower
and higher end totals described above. Heading over the the high
plains north of the region of greater uncertainty described above,
the isentropic lift and theta-e advection will be positioned well to
still produce substantial lift and precipitation. Snow totals
look on track here, but the piece of uncertainty going forward is
the potential for blizzard conditions. There may be a period of
winds reaching blizzard criteria along a band stretching across
Niobrara county, northeast Goshen county, and just north of the
North Platte River valley, and points northeastward. Don't have
the confidence at this time to upgrade to a blizzard warning due
to uncertainty regarding now persistent these winds will be able
to get, but will need to keep a close eye on wind and visibility
trends as a potential upgrade could be needed. Regardless, winds
will be enough to produce significant blowing/drifting snow
through Wednesday morning, but we do thing winds should come down
Wednesday afternoon. Another thing to watch for Wednesday is the
potential for some convectively enhanced snow showers in the
afternoon. Most guidance is showing steep lapse rates and some
elevated instability on top of the bitter cold surface inversion.
Thus, snow activity after midday Wednesday could take on more
spotty, convective characteristics. Winds in the 600-800mb layer
are expected to turn more westerly after 00z Wednesday, which will
start to advect in drier air and bring an end to the snowfall
totals.
The forecast also remains on track for another significant cold air
intrusion. Expecting almost the entire area except the higher
terrain in the SW part of the forecast area to be below 10F by
daybreak, and temperatures will only drop further through the day.
Most will stay in the single digits above to single digits below
during the daytime hours, with apparent temperatures between -20F
and -25F even during the day. There is still strong model consensus
for overnight lows in the -10 to -20F range Thursday morning. Even
with just a little bit of wind, this would be enough to produce wind
chills below -30F, so decided to issue a Wind Chill Watch for
Wednesday night through Thursday morning. Weak warm air advection
resumes Thursday, so the higher terrain should warm quickly (with
breezy conditions likely leading to more blowing snow concerns), but
the high plains will probably remain very chilly.
.LONG TERM...(Thursday night through Tuesday)
Issued at 400 PM MST Tue Feb 21 2023
The progressive large scale pattern will continue through the long
term. The flow aloft splits Friday, with a southern stream upper low
moving through CA/NV, the Four Corners and south central Plains this
weekend into Monday. Shortwave energy in the northern stream dampens
out, with a weak ridge shifting east ahead of the next Pacific upper
trough Monday. This trough gets absorbed by a more dominant upper
ridge, deamplifying Tuesday as a deeper upper trough takes shape
over the western CONUS.
Main concern for Friday through Saturday will be the resumption of
strong winds for the I-25/I-80 wind-prone zones. The 12Z in-house
random forest probabilities for high winds are around 40 percent,
with gusts falling just short of 58 MPH. Another byproduct of the
winds will be blowing/drifting of the newly fallen snow. Travel will
be impacted with the possibility of ground blizzard conditions. Winds
diminish Saturday night and Sunday, then strengthen Sunday night and
Monday. Probabilities for high winds along the I-80 corridor from
Rawlins to Buford are 60-65 percent with gusts up to 65 MPH.
There will be some Pacific moisture interacting with a passing
shortwave and orographic lift Friday to produce snow showers along
and west of the Laramie Range. One to three inches of snow will be
possible over the Snowies/Sierra Madres. Saturday will be dry, with
the next chance of mountain snow showers Sunday/Sunday night and
Tuesday with the passage of additional shortwaves.
Temperatures moderate from the 20s/30s Friday to the 30s/40s
Saturday and Sunday. Temperatures cool slightly Monday following a
frontal passage, then moderate once again Tuesday.
&&
.AVIATION...(For the 06Z TAFS through late Wednesday evening)
Issued at 1052 PM MST Tue Feb 21 2023
Surface arctic cold front has just pushed across most of southeast
Wyoming and western Nebraska late tonight as temperatures drop into
the single digits and teens through midnight. KLAR will remain in
the "warm" sector for the next few hours before the front pushes
south into Colorado. Otherwise, forecast is on track and expect
widespread/persistent snow with occasionally heavy snow.
HAZARDS/WEATHER TRENDS: Persistent IFR to LIFR conditions in snow
and some blowing snow will likely continue through Wednesday
afternoon. The only exceptions are (a) KLAR, which will be battling
downslope easterly winds throughout the event, so kept MVFR
conditions with occasional IFR possible in the heavier snow bands.
(b) KSNY will be on the southern edge of the heavier snowfall, so
not as confident with persistent IFR conditions in snow with a low
chance of LIFR and moderate to heavy snow. Other than some brief
improvement, conditions will likely remain poor through 00z
Thursday.
