Thursday was the “warm before the storm” as most of Montana warmed into the 70s and even low 80s in a few spots. Friday, changes will sweep across the state with a cold front. Expect a significant temperature drop of 20-30 degrees, with highs in the 40s and 50s for western and central Montana. Eastern Montana will be ahead of the front and thus still warm with highs in the 60s and 70s. Rain showers and some snow will move through the state. The mountains along and west of the Continental Divide will see a few inches of accumulation above 6000′. However, at times on Friday the snow level will drop below 5000′. Mountain passes over and near the Divide could be slippery, with mountain temperatures falling into the 20s by afternoon. West winds will howl up to 30mph. Saturday will start out mostly sunny, but clouds will increase across the state through the day. West wind will pick up to around 15-30mph again. Highs will be cool, in the 40s and 50s. A few showers and mountain snow showers are possible late in the day in the western part of the state. Sunday will be mostly cloudy with highs in the 50s and low 60s. Late in the day, some rain and higher elevation snow will spill over the Divide again. Sunday night, a few showers and mountain snow showers will move through. Monday will be partly cloudy and dry, with highs in the 50s and 60s. Tuesday will be another sunny and warm day, before a significant front will bring a big drop in temperatures and the chance of snow on Wednesday afternoon.
Have a great day!
