A strong cold front Tuesday will push temperatures this week down into the teens for highs starting Wednesday and lasting through the start of the weekend. Cold air will become dislodged from Canada as a blocking high pressure system develops over Greenland. That high forces the jet stream northward, pushing the cold air over Canada south into the lower 48. Current temperatures in central Canada are as low as -25°. As high pressure responsible for Canada's cold shifts south into the High Plains Tuesday, it brings the cold air with it.
The air mass will be modified a little by the time it reaches the Stateline, but highs are expected to fall roughly ten degrees below average. It would be even colder if we still had a fresh snow pack on the ground.
Now if you're hoping for some snow to come with the cold, you're going to be out of luck. Between now and next week there look to be few and far between snow chances.
