1003 PM MST Sat Feb 25 2017

.SHORT TERM...(This Evening Through Sunday Night)
Issued at 135 PM MST Sat Feb 25 2017

Clouds and showers have increased across the CWA as
the upper wave pushes into the northern plains. Satellite shows
cumulus expanding over western SD, with stratus lingering over
northeastern WY and far western SD. Radar depicts popcorn showers
developing and moving southeastward through the area. With a surface
trough stretching over the northern plains, winds are westerly.
Temps are in the 20s to lower 30s, colder over the more snow-covered
areas.

Showers will dissipate this evening as the wave shifts eastward.
Clouds will decrease, and lows will dip into the single digits and
teens.

Weak upper ridging and low-level west-southwesterly flow will bring
drier and slightly warmer weather for Sunday. Highs will be
generally in the 30s. Lows Sunday night will be around 10 to around
20.

.LONG TERM...(Monday Through Saturday)
Issued at 135 PM MST Sat Feb 25 2017

Mostly cloudy and mainly dry weather is expected next
week, with near to slightly below average temperatures in the 30s to
low 40s through Wednesday. A slow-moving trough with a couple of
embedded waves will bring clouds and the possibility for showers
Monday night/Tuesday, and again Wednesday night/Thursday. Warmer
weather is expected towards the end of the week, as an upper ridge
builds over the western CONUS.
