Another bitterly cold morning, especially in valleys of southwest Montana, precedes a light accumulating snow event beginning tonight and lasting into Saturday morning. Most locations will see 1-3" of fresh snow.
Today we will experience increasing cloud cover with highs topping off in the teens for most cities. Helena will be stuck in a shallow inversion and will not get out of the single digits.
We will temporarily get a break from the barbarically cold air, but it will come back to some extent this weekend. Another arctic boundary will push south and interact with a passing low-pressure system. I don't think we will get as cold as we've been over the past 3 nights. This will however create an overrunning pattern and, in turn, snow will be present for much of the state.
Another round of snow will begin Sunday night and last into Tuesday morning. This wave of moisture will favor northerly upslope areas like Great Falls and Lewistown.
It is becoming increasingly likely we get one more shot of very cold air on Monday night before temperatures will finally warm back up towards the end of next week.
