Forecast Discussion: More early season Wintery Weather Late week

Discussion: An unseasonably cool airmass will remain in place through the middle of the week with temperatures struggling through the 40s tomorrow and Wednesday and lows falling into the low 30s. A frontal system approaches from the west on Thursday helping to push a warm front into the region late in the day. Warm air overrunning the cold air in place will bring a brief period of light snow or mixed precipitation for areas north of I84 during the early morning on Thursday before rain moves in for everyone late in the day. Rain tapers off Friday morning giving way to mostly sunny and cool conditions.

Surface: A clipper system departs to our south and east today as a cold front boundary pushes farther offshore. Cold high pressure will gradually build in from the north and west over the next couple days. A developing area of low pressure will approach from the west Thursday and move through on Friday, with brief high pressure following before another couple weak frontal systems move through.

Upper Level: The jet will remain overhead or just to our south over the next few days with troughing lingering in the east. A few shortwave troughs will make their way through the area along the periphery of a slow moving southern ridge Thursday through Sunday.
