A WIND CHILL ADVISORY is in effect for northeast Montana through Wednesday morning.

Arctic air once again is moving into Montana but will only make a glancing blow. Wind chill values could be colder than -30 into Wednesday morning in far northeast Montana. Overnight lows will range from near -20 in northeast Montana, to the -0s in central Montana, to the 10s west of the Continental Divide. Arctic high pressure will settle over the state for a chilly but sunny Wednesday. As this high pressure moves out a developing chinook will create downsloping compressional wind that will warm temperatures above average for most of the prairie locations. Highs on Thursday and Friday will climb into the 40s to near 50 there, but the mountains and valleys will stay in the 20s and 30s for highs. This high pressure will stick around making for abundant sunshine through the rest of the workweek. Just like a few weeks ago, grassfires are a possibility with the warmer temperatures, gusty wind, low humidity and lack of snowpack on the ground. The weather setup could be similar to what happened in central Montana earlier in the month when large grassfires developed. Please be careful. The weekend will start out partly cloudy, windy and mild for most areas on Saturday. Highs again will be in the 40s to near 50. The run of sunshine will end on Sunday as the next storm arrives. A cold front will deliver a burst of snow, wind and falling temperatures. The snow on Sunday should be fairly intense, but accumulation should be limited to the mountains yet again. However on Monday and Tuesday, an area of low pressure could bring a chance of accumulating snow to the lower elevations. There is a chance of a few inches of snow, but at this time there still does not appear to be any major winter storms that will have a crippling impact on the state.
Have a great day!
