Weather Discussion & OutlookA very large and unusually cold Trof of Low pressure that spans across all of southern Canada and the northern tier of the US with below zero temps persisting all the way fro the valley floor to 10,000-ft., and beyond!
A secondary Trof of Low pressure over the Pacific Northwest today will swing across Idaho the next 24-hrs. and actually bring slightly warmer air over us in a SW flow Saturday. Then that is followed by a colder NW flow again for Sunday & Monday.
Some moisture with that Trof moves over us today and Saturday, then dries out as we go thru Sunday.
Not a lot of moisture, just too cold for the atmosphere to hold much. And very weak dynamics in the atmosphere, so donít expect much more than a few inches of accumulation in the mountains the next few days.
Weather pattern changes more significantly next week, as we get into more of a Westerly flow Tuesday thru Friday with temperatures also warming up.
Pacific moisture gets into that flow with best chances for snowfall coming later Thursday into Friday, the way it looks right now.
