Scattered showers and even a few thunderstorms are possible during the first half of Thursday night.
Temperatures will actually rise through the evening well into the 40s. The combination of rain and melting snow will cause localized flooding, so the National Weather Service has issued a Flood Advisory until 11:30 p.m. Thursday night generally for areas south of Interstate 69.
Strong wind will develop coincident with the passage of a cold front between midnight and 2 a.m., with wind gusts to 50 mph certainly possible. Accordingly, the National Weather Service has also issued a Wind Advisory from midnight through 7 p.m. Friday. Strong wind will continue through the night, as temperatures fall into the low to mid 30s by dawn.
Continued very windy on Friday with scattered snow showers and snow squalls, especially across our northern suburbs. Temperatures steady in the low to mid 30s for the first part of the day, then falling by late afternoon. SW wind at 25 to 30 mph, with higher gusts.
The period from Saturday through the end of next week should be mostly dry with varying amounts of sun and clouds. There’s always the chance for a weak disturbance to generate a few light snow showers, but nothing is showing up now on my longer range computer models suggesting anything in the form of accumulating snow this coming week.
Temperatures, however, will be a story. As I’ve been mentioning since last week, that Polar Vortex you heard a lot about (and grew to greatly dislike) back in January will be sinking south once again next week. Highs temps will drop from 30s on Saturday, to 20s on Sunday, to near 20 on Monday and Tuesday, and farther down into the teens for Wednesday and Thursday.
Overnight lows by Wednesday and Thursday will be down into the single numbers -- pretty brutal by end-of-February standards.
