Arctic air before a wild weekend

Good Wednesday to one and all. We have an arctic air mass moving in later in the day, and it will bring the coldest air of the season over the next few days. From there, it’s game on for a wild weekend of weather across our region.

The arctic front arrives by Wednesday evening, with the really cold stuff settling in Thursday and Friday. Morning lows by Thursday can reach the high single digits in the north:

Thursday’s highs should range from the upper teens to the low 20s, but gusty winds will make it feel much colder.

The weekend system continues to look pretty awesome from a meteorological standpoint. Friday starts with arctic air in place and the potential for some overrunning light mix late in the day.

Temps then rise Friday night and Saturday, and the high might hit the low 60s on a gusty southwesterly wind. Showers and some rumbles of thunder will be possible.

The arctic front then moves in Saturday night and early Sunday, undercutting a pretty notable precipitation shield. As temps drop into the teens and 20s, things could get ugly for a time. Sleet, freezing rain and some snow will all be possible. Here’s the GFS breakdown:

Is that an hour or two of sleet, freezing rain and snow? Is it several hours? If the answer is the latter, we will have some bigger problems. Also, all that water from the Saturday rain will freeze up very quickly.

The arctic air continues to settle in for Sunday night:

Make it a great day and take care.
