BILLINGS — Good morning!
As the stronger winds subside, a cold front sinking down from the north will create breezy conditions in its wake today, but mixing will allow for warmer temperatures, some areas pushing a good 10+ degrees above normal. Cooler air begins to filter in Thursday, bringing near seasonal daytime temperatures back into play.
Expect a pattern change Friday into the weekend that will bring colder highs and lows plus a chance for at least some light snow. A split trough (separate low pressures to the north and to the south) will spawn snow showers in western Montana and northwestern Wyoming Thursday, southern Montana and northern Wyoming Friday, and across most of Wyoming Saturday. Accumulation estimates could change, but for now going with up to 1” for western and southern Montana, half-2" for southwestern Montana, half-1.5” for northwest to northern Wyoming, and little to no accumulation for eastern Montana. Billings looks to get no more than half an inch.
That cooler air will knock highs down into the 20s and lows into the teens Friday and Saturday. Downslope winds will bring a brief warmup Sunday and Monday before an upper trough brings a return to cooler temperatures and the possibility of more snow by Tuesday.
