Weather will stay relatively calm for the next couple days as a large high pressure system continues settles in over the state. There is no immediate concern for precipitation for the next couple of days. On the other hand, a matter of concern will be the low temperatures tonight and tomorrow night falling down to less than 10 below zero for northern counties tonight, and around zero for Tuesday. With the air temperatures reaching such low levels road surface temperatures will fall to well below freezing by early hours of the morning.

Warm air advection will cause temperatures to rise over the state starting on Wednesday because winds will have shifted to a southerly direction from the tail end of the current high pressure. Models are showing some areas could see highs above freezing. Models are also showing the next chance for precipitation for late Thursday/early Friday as another clipper-type system will track to north, associated with an upper-level vorticity maximum. Critical thicknesses are showing the state will remain in a frozen precipitation domain.
