.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 105 PM MST Sun Nov 10 2024

The short term forecast includes a much different weather day
compared to yesterday at this time. Surface observations have
daytime highs in the 50s and 60s, especially east of I-25 into
the western Nebraska Panhandle area. Dry and mostly sunny
conditions have also assisted with melting what little snowfall
resides across portions of far southeastern WY. The dry
conditions should continue the remainder of today with breezy
winds along the gap and wind prone areas through sunset.

Upper level ridging will persist through Monday as mid-level
heights increase modestly through the day. We should see another
mostly sunny and dry day, with daytime highs being as warm as
today, if not a couple of degrees warmer. This will translate to
daytime highs in the upper 50s to near 70 degrees along and east
of the I-25 corridor.

A surface cold front will quickly advance southeast from the
Great Basin on Tuesday. Strong winds aloft will quickly advance
toward central and southeast WY on Tuesday. Additionally, a
stout upper level wave will propagate aloft at H5/H3 from the
Pacific Northwest on Tuesday. This will be a quick-moving
disturbance aloft, causing rain and snow showers to be present,
with a transition from west to east to snow showers by Tuesday
evening. Have bumped up the winds for Tuesday evening into the
early Wednesday morning hours. In-house probabilistic data
continues to hint at possible high wind headlines for the gap
areas of I-80 and I-25 for that time period. Will continue to
monitor the trends in the event that a high wind headline is
needed. Overall, a nice couple of days in store for the region
after a chilly past couple of days for the cwa.

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
Issued at 105 PM MST Sun Nov 10 2024

Wednesday...Cooler temperatures develop in the wake of a cold
frontal passage and with zonal flow aloft developing. With 700 mb
temperatures near 2 Celsius, maximum temperatures will only be in
the lower 40s west of I-25, and upper 40s to mid 50s east of I-25.
Continued breezy to windy based on the projected low and mid level
gradients.

Thursday...The flow aloft backs from westerly to southwesterly
inducing another surface lee trough development, and with 700 mb
temperatures rising to near 3 Celsius, highs will warm to the upper
40s to lower 50s west of I-25, with upper 50s to lower 60s east of I-
25. Continued breezy to windy based on the low and mid level
gradients.

Friday...As another shortwave trough aloft moves into the Great
Basin states, our flow aloft remains southwest with 500 mb heights
falling about 80 meters, thus slightly cooler temperatures expected
with low and mid level gradients suggesting another windy day,
especially for our Wyoming wind prone locations such as Arlington,
Bordeaux, Vedauwoo and the I-80 Summit.

Saturday...Cooler and breezy in the wake of a shortwave trough aloft
and its associated cold frontal passage. 700 mb temperatures near -6
Celsius will yield maximum temperatures in the lower to mid 40s west
of I-25, with mid 40s to mid 50s east of I-25. A slight chance for
snow showers west of a Douglas to Laramie line.

Sunday...A secondary shortwave trough aloft and its associated cold
front move across our counties, producing even cooler temperatures
with 700 mb temperatures near -9 Celsius yielding maximum
temperatures from the upper 30s to near 50 degrees. Low and mid
level gradients suggest another breezy to windy day.
