Band of rain will pass overnight to early Thursday morning. A couple of embedded isolated storms are possible.
The only way we would get an embedded severe storm is if one of those storms can tap into the very strong wind fields in the lowest 7,000' & transfer it to the ground. Winds at 5,000' are forecast at 85 mph & winds at just 2500' will run around 65 mph. So, that random sudden gust cannot be ruled out. I have seen them in these situations before.
However, there is a window for just high non-t'storm winds from the south with the band & just behind it of 20-30 mph (sustained) with gusts 45-60 mph. Wind Advisory is up for the entire area with High Wind Watch up in eastern Illinois as a result.
Winds will be strong tomorrow (Wind Advisory up viewing area-wide with High Wind Watch in eastern Illinois.
There will be periods where the winds get very strong. Periods of sustained winds of 20-25 mph with gusts 35-45 mph will be interspersed with sustained winds of 25-35 mph with gusts 45-60 mph. Southerly winds initially will turn to the southwest after the storms (see below).
Two broken lines of storms are possible Thursday in the 11 a.m.-4 p.m. time frame.
Isolated to some scattered severe weather is possible with main threat being wind & the secondary threat isolated tornado or two if instability can still get going nicely.
The more robust, widespread severe risk will tend to develop southeast & east of our area, but we will watch closely in model runs overnight to see if that widespread threat near to be shifted west & northwestward into the area.
Once the storms exit, skies should clear & temperatures begin to fall late afternoon-early evening. Low clouds should then pivot in as we drop from the 50s to the 40s in the evening after highs Thursday at 67-71.
Some scattered rain/snow to scattered snow is likely Friday morning-early afternoon as temperatures fall into the 30s.
It will be windy in the morning-midday with gusts to 35-40 mph. Gusts should drop to 25-30 mph by afternoon.
Somre breaks in the clouds are possible by evening.
