Area Forecast Discussion
National Weather Service Cheyenne WY
1022 PM MST Sun Nov 8 2020
.UPDATE...
Issued at 702 PM MST Sun Nov 8 2020
...Light to occasionally moderate snow tonight for the eastern
plains...
Current forecast for tonight and early Monday looks on track, with
KCYS radar loop showing some midlevel snowfall developing along
and just east of the I-25 corridor. Expect this trend to continue
over the next few hours as the upper level trough near the four
corners region slides eastward. A strengthening upper level 135
knot jet will be located across the eastern plains tonight, with
impressive difluence aloft shown through noon Monday. For now,
kept the 1 to 2 inches of snow along and east of the I-25
corridor. However, we expect some locations to see as much as 3-5
inches in the heavier bands of snow. Low confidence in the
placement of these heavier snow bands, so will hold off on Winter
Weather Advisories for now. Did note some really low dewpoint
temperatures at the surface this evening, so the snow may take a
while to reach the ground.
&&
.SHORT TERM...(Tonight - Tuesday)
Issued at 232 PM MST Sun Nov 8 2020
Snow chances are expected to increase significantly this evening &
overnight as a deep upper-level low continues to spin over much of
the western CONUS. A more substantial piece of mid-level energy is
expected to eject northeast from the 4 Corners region after around
06z, impacting the high plains of southeast WY and western NE thru
18z Monday. There is growing concern that a band of heavy snow may
develop from near Cheyenne northeastward through Chadron overnight
tonight through early Monday. This area will be in the favored LFQ
of an intense/140 knot H25 jet, well-placed beneath persistent low
level frontogenesis. A broad area of negative saturated EPVS would
indicate the presence of instability and resultant locally heavier
snowfall rates. Ensemble plumes do not support significant amounts
of snow, but trends in the HRRR have been toward heavier, and more
widespread precipitation overnight. Confidence in a swath of snow-
fall amounts of 1-2 inches (locally 2+) is growing, so this is the
main change to the inherited forecast for tonight. Advisories will
hopefully not be needed, but this will be something to watch.
Snow showers will persist through much of the day on Monday w/ the
potential for light accumulations mainly west of the Laramie Range
and in the mountains. In general, expect an inch or two in the low
elevations with 3-6 inches in the mountains through late afternoon
on Monday. The focus will shift toward high winds Monday night and
Tuesday as another short wave sweeps east across the northern high
plains. The resulting pressure falls will increase 700/850 mb CAG-
CPR gradients into the 60-70 meter range along with 55-65 knots of
700-800 mb flow over the wind prone areas. We have gone ahead with
a High Wind Watch for 03z Tuesday through 06z Wednesday.
.LONG TERM...(Wednesday - Sunday)
Issued at 257 AM MST Sun Nov 8 2020
Generally cool to mild conditions across the CWA this period with
several shortwaves passing across in a progressive pattern. One
looks to scoot across late Weds with the next ones late Friday
and late Saturday. Not much in the way of pcpn with these outside
of the higher mtns where periods of snow showers are expected.
Temperatures fairly close to seasonal averages along with periods
of gusty winds with the passing of these systems.
&&
.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1022 PM MST Sun Nov 8 2020
VFR conditions have held steady across all terminals over the past
6 hours, the next 6 hours a different story. Latest GOES-E
nighttime microphysics shows middle to high level clouds advecting
northeastwardly though a layer of low clouds under 4 kft starting
to advect to terminals in the forecast area. Coupled with colder
temperatures in response to frontal passage, moisture and
frontogenic forcing will contribute to precipitation formation
through the overnight/early-morning hours. Confidence of timing
of lifting away from forecasted MVFR/IFR conditions Monday
afternoon is low with decent variation in model data expected to
persist for next 6 hours as a mid- level energy coupled with
frontogenic forcing will contribute to an overnight increase in
snow and mainly MVFR to IFR conditions for majority of terminals.
With heavier bands of snow cannot rule out that conditions may
decrease to LIFR though adequate monitoring of obs downstream will
be needed for any amendments.
&&
.FIRE WEATHER...
Issued at 257 AM MST Sun Nov 8 2020
Elevated fire weather conditions linger yet another day across the
western Nebraska Panhandle's I-80 corridor with only a short
window of opportunity to receive light precipitation this morning
as a strong cold front passes through the region. This front is
currently situated just west of the Laramie Range, and has been
associated with strong and gusty winds. These winds will continue
to effect the region with High Wind Warnings in place for the
wind-prone areas of southeast Wyoming and most of the Nebraska
Panhandle. Quick, light shots of moisture will remain for most of
the week, though the mountains look to receive the most
precipitation. The windy pattern will remain as well. Minimum
humidities drop into the 20s again at the end of the week.
