Rain, snow, and a couple of thunderstorms will impact the state tonight and through this weekend.
Winter Weather advisories have been issued for up to 10 inches of snow in the mountains of southwest and north-central Montana through early Sunday morning.
Heavy rain and snow will come in two waves, at times. The first is coming through tonight, and the second will reach western Montana tomorrow night.
Snow will reach lower elevations as well, but accumulating snow will be a more tricky forecast, especially for valley locations. We have had very warm ground temperatures over the last few days. Nevertheless, expect a rain/snow mix early this evening converting over to snow late tonight. We could see as much as an inch in Helena. Driving conditions over mountain passes will be poor and we could see some isolated power outages in higher elevations with heavy, wet snow.
Conditions stay slightly cooler than normal into most of next week, with a pattern change coming in the second week of April.
