What a gloomy few days here across the state with cloudy skies and cold temperatures.  An increase in a westerly flow aloft will push out some of the clouds into Tuesday morning, and by Tuesday afternoon there will be mostly sunny skies across the state.  A stronger wind will develop off the Rocky Mountain Front and across north central Montana.  Wind gusts could top 40mph through Tuesday.  Highs will top out in the 20s and 30s.  Wednesday, an arctic front will move through the state in the morning hours.  A period of light snow is possible along this boundary, but any accumulation will be light.  High temperatures in the 20s will occur in the morning hours, as temperatures will fall through the 10s Wednesday afternoon and evening.  Overnight lows into Thursday morning will be in the 0s and -0s.  Northeast Montana could be as cold as -10 to -15.  Wind chill values Wednesday night will also drop below 0.  This cold airmass will not stick around long, as the core of the cold heads east on Thursday.  Temperatures will rebound under sunny skies into the 20s to around 30.  Besides that brief arctic airmass, the weather will be quiet heading into the weekend.  Friday through Sunday will be mostly sunny with highs in the 30s and 40s over the valleys and plains, 20s in the mountains.  The next snow event will likely hold off until the middle of next week.

Have a great day!
