A WINTER WEATHER ADVISORY is in effect for elevations above 5,500' in the Little Belt and Big Belt Mountains of central Montana, and for the Glacier Region.
A HIGH WIND WARNING is in effect for southcentral Montana until noon Thursday.
A diversified spring storm is spreading thunderstorms, rain, wind and snow through the state. Snow levels will drop through the evening and mountain passes may have difficult driving. MacDonald Pass west of Helena is one area that has seen several inches of heavy, wet snow. Rain, wind and mountain snow will continue into Thursday morning. In a few areas, snow levels could drop to as low as 4000'. Lewistown is a particular area that could have a slushy accumulation early on Thursday morning. Showers and higher elevation snow will continue through the morning but taper off through the afternoon as the low pressure moves away. Highs will be held down by cloud cover, as most locations will stay in the 50s. Some areas west of the Continental Divide and out along the Hi-Line could have more sunshine with highs reaching the 60s. Another low pressure will move through on Friday with scattered showers and thunderstorms. Highs will be in the 50s and 60s, 30s and 40s in the mountains. This weekend will start out sunny and beautiful on Saturday with highs in the 50s and 60s. Sunday is Mother's Day and the weather unfortunately will not be as nice. There will be more clouds than sun with a few showers and mountain snow showers. Highs will only be in the 40s and 50s. More unsettled weather will prevail next week with showers and thunderstorms likely for at least Monday through Wednesday. Temperatures will remain near to slightly below average.
Have a great day.
