A RED FLAG WARNING has been issued for portions of northeast Montana until tonight.
A WINTER STORM WATCH will go into effect Wednesday evening until Saturday morning for the Rocky Mountain Front and central and southern Lewis and Clark Counties.
The week will start dry, warm, breezy, and sunny. These conditions, along with low relative humidity, will increase the fire concern for portions of northeast Montana. Today's high temperatures will climb into the 70s and 80s. Record warmth will be challenged across the state.
Tuesday will be another pleasant day. A few stray showers may linger across the state. The high temperatures will begin to cool into the 60s and 70s as our next weather maker moves in off the Pacific. Daytime highs in eastern Montana remain in the 80s.
By mid-week, a potent cold front will bring rain/snow and below-average temperatures back into the region. Daytime highs will fall into the 50s and 60s. Most of the heaviest snow accumulations will be at or above pass level. Up to 12" of snow could fall along the Rocky Mountain Front, and between three to six could fall in some locations in north-central Montana by Saturday morning. The snow could impact travel over mountain passes, including: Rogers, Kings Hill, MacDonald, Marias, and Homestake pass.
By Thursday, a cooler air mass will settle in, and daytime highs will fall into the 30s and 40s. More rain and snow will be on the menu until Saturday morning.
