DISCUSSION.

Tonight through Saturday night .

High pressure building to the west and lee-side troughing over central Montana will cause surface pressure gradients to tighten this evening and overnight. As a result, winds will increase along the western foothills with gusts into the 50s mph for places like Livingston and Nye later this evening and overnight. Winds will gradually decrease on Saturday as the ridge axis slowly shifts east over the region. Highs on Saturday will be up a few degrees, with temperatures in the 50s and 60s, coolest over the far east where snow cover will linger. STP

Sunday through Friday .

Dry and mild on Sunday and Monday before cooler weather moves in for the middle of the week. An upper level low will swing across northern Nevada and northern Utah. This low then works across central and southern Wyoming and then into the central plains Tuesday and Wednesday. This will pull cooler air into the northern Rockies and generate some lift for an increasing chance of precipitaton. The system has been trending south and today is no exception. Even the farther north reaching ECMWF has shifted it a little farther south today. This will focus the best chance of precipitation south of a Livingston to Billings to Ekalaka line. Temperatures will be on the warm side, so it looks like most of the precipitation will be in the form of rain, with a rain and snow mixture possible Tuesday night into Wednesday. The Bighorn mountains will have the best chance of several inches of snowfall, along with locations south of Sheridan. Ridging builds back Thursday and Friday for drier weather with a warming trend. TWH

AVIATION.

Breezy conditions can be expected along the western foothills through the period. Southwest winds will increase through the evening, reaching gusts up to 45 kts at KLVM and K6S0 overnight. Otherwise, VFR conditions will prevail. STP
