The cold comparison to normal

The cold comparison to normal

Here we are on a Friday night with temperatures still rising. Our 10pm temperature is 40 degrees with a gusty south wind. Not one of the models is right with this observation! So, old fashioned Meteorology tells me that with a stiff southerly wind continuing, our temperature won’t fall at all. However, the wind will likely come down by morning. This will cause temps to fall to around freezing by morning. Some of the rural valleys with snow on the ground will be much colder…possibly into the high teens! So if you have a quick-changing car thermometer, you may see some wide variations if you’re out early in the morning.

The ECMWF computer model takes us below zero Sunday afternoon!

On Saturday, temperatures will surge well into the 40s, even with snow on the ground! 45 in Rockford is some 15 degrees above normal. 50s will be possible in far southern Lee County and Southern Illinois could near 60 in spots!

But it all ends there as a significant cold front arrives Saturday night. So get ready for a wild ride with middle 40s Saturday afternoon and single digit temperatures Sunday afternoon! Throw the wind chill factor in there and we’ll have a 50° drop in a matter of 18 hours or so!
