Few clouds on shortwave IR imagery early this morning with H5
open wave lifting northeast through the east central plains,
while more zonal flow across the Rockies creating orographic
clouds to the west along the front range. Fairly dry air aloft
through 700mb with chance of flurries bleak through noontime
today. The combination of the H5 analysis and satellite show
closed low over the Hudson Bay while ridging to the west and

.SHORT TERM /THROUGH THIS AFTERNOON/...
Issued at 305 am CST Fri Dec 1 2023
Today clouds will be on the increase while temperatures remain
below normal with highs in the 30s. Surface high pressure
ridging southwest and south from the Great Lakes to the high
plains in western Nebraska builds east that will produce light
east winds that will become southerly in the afternoon west to
the eastern Panhandle. The leeside tough extending south along
the front range will also push east this afternoon where
moisture will pool in the west for increasing clouds. Moisture
will be limited below 8Kft with the mention of flurries or
sprinkles through noontime removed. The forecast is for dry
weather going into tonight through the weekend with near normal
temperatures for early December.

Issued at 305 AM CST Fri Dec 1 2023
Tonight through Sunday a pattern change will bring some
relief from the recent cold spell with unseasonal warmth for
the area to start the work week. The closed upper low near the
Hudson Bay will move westward across Canada and weaken.
Temperatures tonight through Sunday will be seasonal with
overnight lows in the teens and daytime highs in the 40s.
Heights then rise along the west coast with the upper ridge to
strengthen and build east to the plains through Thursday.
The upper ridge builds east to the plains through Wednesday
with periods of clouds but a dry forecast through Thursday.
The increasing zonal flow aloft aloft will limit moisture for
dry weather and warmer air to return. Monday high temperatures
will reach into the 50s with some areas across southwest
Nebraska to reach into the lower 60s. Temps slightly cooler
Tuesday then temperatures mainly in the 60s Wednesday for
temperatures around 20 degrees above normal for early December.
