Snow showers Thursday before a cold weekend


Snow’s to fly before lunchtime Thursday — then on and off into Friday — as the first phase of a multi-week cold period takes hold in the wake of Wednesday’s wind driven rain.

Wednesday was Day #6 without sun, a streak showing little sign of giving up anytime soon. And now out attention is turning to downtrending temps, a development which is to take us into a cold weekend.

Wednesday’s drenching, wind-driven rains are taking place in the “warm sector” of a powerhouse winter storm which has brought a blizzard to the Plains, measurable snow to the Upper Midwest and tornadoes to the South.

Backwash snow showers will be in the air here in the Chicago area by lunchtime Thursday and from time to time moving forward through Thursday night and into Friday. A modest covering of snow appears a distinct possibility as temps drop and the snow showers sweep the area.

Cold air arrives for the weekend

Gusty winds will add to the chill through Saturday.

Looks like frigid arctic air will be in firm control by the time the holiday is here with daytime teens Christmas weekend (the weekend after the one immediately ahead) and nighttime lows in the single digits.

Frigid arctic outbreak follows later next week into Christmas week with snow possibility being monitored in the Wednesday night into Friday morning time frame, but not yet a slam dunk as an accumulation producer.

There are all or parts of 27 states under a National Weather Service watch, warning or advisory with the current storm Wed morning.
