A WINTER WEATHER ADVISORY is in effect for the Glacier area, the Rocky Mountain Front, and several of the mountain ranges in central and southwestern Montana until 6am/9am/12pm/6pm Tuesday.
There are going to be areas of rain and mountain snow around this evening and tonight as a storm system continues to impact our area. The heaviest precipitation will gradually shift eastward as the night goes on and snow levels will get as low as 5000-6000 feet. Tomorrow will not be as wet as today was, but showers and a few thunderstorms are likely, especially during the afternoon and evening, so keep a rain jacket handy. We are also going to have overcast skies tonight and mostly cloudy skies tomorrow.
Up to 6 inches of new snow accumulation is possible in the mountains through tomorrow evening, with the highest snow amounts expected in the mountains in central and southwestern Montana. Watch out for slick roads if you are going to be traveling in the mountains or over any of the mountain passes, especially late tonight and tomorrow morning. Up to a half inch of additional precipitation is also possible through tomorrow, with higher precipitation amounts possible in northeastern Montana.
It is going to be chilly tonight as lows are going to be in the mid to upper 30s and low to mid 40s, and areas of frost are possible, so make sure you protect any sensitive vegetation that you may have. It is then going to be warmer tomorrow than it was today, but it is still going to be cool as highs are only going to be in the 50s and low 60s in most locations.
We are then going to have nicer weather on Wednesday with mostly sunny skies, drier conditions (just some isolated PM showers and thunderstorms around), and warmer temperatures as highs are going to be in the mid to upper 60s and low 70s.
On Thursday, we are going to have mostly sunny skies with some scattered showers and thunderstorms around, mainly during the afternoon and evening, as a disturbance passes through our area. There are then going to be scattered showers and thunderstorms around on Friday as another disturbance passes through our area. We are also going to have partly cloudy skies on Friday. It is also going to be warmer on these two days than it is going to be tomorrow and Wednesday as highs are going to be in the 70s in most locations.
For this weekend, we are going to have nice summer weather as we are going to have mostly sunny skies, mostly dry conditions, and warm temperatures as highs are going to be in the mid to upper 70s and low to mid 80s on Saturday and the 80s and low 90s on Sunday.
