Strong winds in Illinois Saturday PM

There was only one small EF-0 tornado in Illinois Saturday PM, but a large area experience strong to severe winds on Saturday.

Fortunately, the water level of Lake Michigan has dropped over the last couple years and that reduced the amount of lakeshore flooding and beach erosion. The wind and rain knocked quite a few of the remaining leaves off the trees.

Cooler air will move in behind a cold front, but the overall pattern will remain warmer than average through Thursday – then some cold air moves in starting on Friday. It may be cold enough for some snow next weekend.
