——————————————————————————————————————————

Winter Storm Watches have been issued for most of the mountain ranges of southwest Montana ahead of a low pressure system bringing colder air and lots of moisture.

Isolated showers and thunderstorms will start developing around 1 PM today and become more numerous in central Montana around 3-4 PM. Today will be slightly warmer than yesterday with temperatures in the 60s.

A heavy rain and snow event will occur on Wednesday and Thursday. Up to 2 inches of rainfall is possible across much of the western half of the state, a region already hard hit by heavy wet snow a couple of weeks ago. Heavy wet snow is possible from the Rocky Mountain Front to the mountains of southern Montana. Temperatures will be in the 40s and 50s during this period.

Another system will roll in for Memorial Day Weekend. As of right now, this storm will not bring the 40s like our midweek storm will, but a lot can change with track and intensity between now and then on our model runs.

Memorial Day itself will be a beautiful mostly sunny day with temperatures in the 70s.
