Weather Blog

Peoria, Ill. (WMBD) – Central Illinois will experience a bit of weather whiplash over the next week as we experience some large temperature swings. Thanks to gusty southerly winds, high temperatures are expected to reach the mid to upper 80s on Saturday. However a series of cold fronts will bring reinforcing shots of cool air to Central Illinois from Sunday through Friday which will send those temperatures into the 50s by Thursday.

This doesn’t appear to be a record setting cold spell, but temperatures are likely to be 10-20 degrees below average. From October 1st through the 3rd high temperatures are expected to be in the mid to upper 50s while overnight low temperatures will be in the 40s and 30s. It is not yet clear how cold our temperatures will get, especially at night, but if the colder models prove to be correct parts of Central Illinois could experience their first frost of the season by the first weekend in October.
