A WINTER WEATHER ADVISORY is in effect for portions of central, western, and southwestern Montana until 12am/6am Wednesday or 3pm/6pm Wednesday.
There have been areas of snow and rain around throughout the day today, especially in central Montana, and snow totals have ranged from nothing at all to a couple feet of snow! As we go through this evening and tonight, snow is likely around Helena, and there are going to be some scattered rain/snow showers around in north-central Montana, generally in western and southern portions of north-central Montana, including around Great Falls, Stanford, and Lewistown, as a storm system continues to impact our area. For tomorrow, we are going to have mostly to partly cloudy skies with some scattered snow, graupel, and rain showers around throughout the day.
In the lower elevations that see snow, up to 5” of new snow accumulation is possible through midday tomorrow, but most of us will receive <1” of new snow accumulation. In the mountains, up to 12” of new snow accumulation is possible through midday tomorrow, but most mountain ranges will receive <6” of new snow.
This new snow will cause roads to be slick/snow-covered in some areas tonight and tomorrow morning. Also, in a lot of locations, the moisture on the roadways from today’s precipitation will freeze tonight as lows are going to be in the mid to upper 20s and low 30s. This will cause the roads to become slick even in areas that do not receive snow accumulation overnight. If you are going to be traveling anywhere tonight or tomorrow morning, please drive carefully and give yourself some extra time to get to where you need to go!
It is also going to be cool tomorrow as highs are going to be in the 40s and mid to upper 30s. There is also going to be a bit of a breeze around tomorrow, especially in locations east of I-15, as sustained wind speeds are going to be between 10 and 20 mph.
There are then going to be areas of snow around later tomorrow night and on Thursday as a cold front passes through our area, and light snow accumulations of a coating-3” are possible in the lower elevations. It is also going to be chilly on Thursday as highs are going to be in the 30s and low 40s in most locations. There is also going to be a bit of a breeze around on Thursday as sustained wind speeds are going to be between 10 and 20 mph.
There are then going to be a few isolated snow showers around on Friday, generally in the mountains and generally during the morning. We are also going to have mostly sunny skies and cool temperatures on Friday as highs are going to be in the mid to upper 30s and low to mid 40s.
Nicer weather is then expected this weekend as an upper-level ridge is going to be in control of our weather. This weekend, we are going to have mostly sunny skies, dry conditions, and just a little breeze. The temperatures are also going to warm up a lot this weekend as highs are going to be in the 50s on Saturday and the mid to upper 50s and low to mid 60s on Sunday.
As we head into early next week, we will continue to have pretty nice weather as we are going to have partly to mostly sunny skies and mostly dry conditions (just a couple isolated showers around). The temperatures are also going to be well above average for this time of year early next week as highs are going to be in the 60s on Monday and the 60s and mid to upper 50s on Tuesday. The wind will also make a return early next week as it is going to be breezy on Monday as sustained wind speeds are going to be between 10 and 20 mph and it is going to be windy on Tuesday as sustained wind speeds are going to be between 15 and 30 mph.
