Another spring snow event (Updated)!

Another spring storm is bringing snow showers to the low elevations and heavier amounts of snow to the mountains. It was  hard to see the sun through the clouds today.

Any rain will change to snow later today and tonight. Heaviest snowfall will be in parts of SW Montana and central portions of the state. Snow continues overnight before decreasing later Friday. See the NWS weather statements below.

Overnight snow likely with a low near 27. It is possible to see an inch or two of snow by morning.

Friday snow in the morning with a mix of rain and snow by afternoon. High in the upper 30’s with gusty northwest winds. Again not much in the way of snow accumulation is expected, perhaps another inch of snow.

Saturday mostly sunny as gusty Chinook winds returns and that means warmer weather! High in the upper 40’s with a slight chance of rain showers.

Sunday partly sunny and mid 50’s for an afternoon high, good enough weather for some outdoor activities.

Monday partly sunny with showers and a high near 50.

Tuesday and Wednesday partly to mostly sunny and highs stay in the upper 40’s and a chance of showers both days.

I hope you have a great evening.
