Another wave of moistures will move into Southern Idaho this afternoon. In the valley we could see a mixture of rain and snow and in the mountains mostly snow. Winds will remain calm today. Tonight temperatures will drop into the mid to upper 30's for the valley and in the mid 20's in the mountains with rain and snow showers.
Showers stick around Sunday but since temperatures will be warmer just rain in the valley and rain and snow showers in the mountains. Temperatures in the valley will warm up to the lower 50's in the Magic Valley and in the lower 40's in the mountains. Winds will pick up out of the west and will vary between 15 to 25 mph. This could create blowing and drifitng snow which will reduce visability create difficulty while traveling. A chance of rain showers in the valley will spill over into the begining of next week with mild temperatures.
Can we expect a white Christmas? Models are starting to come into agreement. They at least agree that we will see a storm system moving through the region Christmas Eve night into Christmas Day, what they don’t agree on is how cold temperatures will be and how much if any snow we will get. Until we get all of the details in place we are giving the odds of a white Christmas in the valleys at 30%.
