Patchy fog returns Tuesday night as above normal temperatures continue

 

Tuesday may have been a little breezy from time to time but it sure was a nice afternoon. Temperatures jumped a good 20 degrees from Monday, rising into the mid 70s for most. The warmth will continue through Tuesday evening as a cold front slowly sinks south during the night. There were a few very isolated showers/thunderstorms that developed during the late morning and afternoon from southern Wisconsin into northeast Illinois. A few of those showers did slide through southern DeKalb and Lee counties. Now, most of that activity has moved out over northern Indiana.

As the front comes through tonight winds will turn to the east and northeast. This may allow some patchy fog to be pulled inland from Lake Michigan, impacting some of northeast Illinois. But any fog that does develop shouldn't last too long and temperatures are expected to warm back into the mid-70s Wednesday afternoon.

High pressure building in Wednesday afternoon will conditions dry through Thursday evening but the chance for a few showers and thunderstorms return late Thursday as a cold front moves through northern Illinois and southern Wisconsin. As it stands Tuesday evening, our severe threat remains low - with a higher threat for severe weather west of the Mississippi River during the afternoon and evening. Should the cold front speed up then there could be a couple thunderstorms we'd have to watch to the west. And if the front slows down at all, then we may see the storm threat carry over into Friday afternoon.
