WEATHER DISCUSSION: Temperatures begin a recovery today from the colder temperatures we saw Friday. Highs still in the mid to upper 30’s and lows in the 20’s/30’s, Sunday’s temperatures look to increase significantly, back into the 40’s and above average. Mostly clear skies are expected across the region this afternoon as high pressure has built in over the state. Clouds will increase through the night along with winds as another approaching weather system from the Pacific Northwest settles in. This will bring light snowfall along the Rocky Mountain Front and mountains across Southwest Montana south of the I-90 corridor.
Moisture continues through Monday as temperatures remain below freezing through this time period. A quick moving upper-level shortwave will move from North-Central Montana southward across Central and Southwest Montana for Sunday night into Monday morning. Light snowfall is forecasted across the region with snowfall amounts between a trace to a half inch, making the morning commute on Monday potentially slippery as surface air temperatures are forecasted to be below freezing. Temperatures on Monday will be near seasonal averages (in the 30s) as the shortwave trough brings some cooler air to the region. After this shortwave moves through, dry conditions return as upper level ridging builds back into the state. Temperatures after Monday become seasonably above average with highs in the 40s to 50s on Wednesday and Thursday.
