Talk about irony -- the fall-like weather we've enjoyed the past few days gives way to summertime heat and humidity, just in time for the start of Meteorological Fall!

Thursday's forecast offers another chilly start with temperatures at daybreak flirting with the record low at 51°, first set on August 27, 1967. Once the sun rises, temperatures will start to rise rather quickly through the morning and winds will start to shift to the southeast by afternoon, helping to boost temperatures to the low 80s by Thursday afternoon.

Temperatures will continue to slowly warm Friday and into the weekend with afternoon highs reaching the mid 80s by Sunday. The cooler air mass is yielding to the summertime heat as high pressure glides eastward and winds shift southward to allow seasonal air to filter back into mid-Illinois.

The weekend forecast also includes the chance for scattered showers and storms by Saturday morning as a weather maker crosses the plains into the Great Lakes. The majority of the rain and thunderstorm activity is expected to track from Iowa into northern Illinois and southern Wisconsin. But as a trailing cold front drops through mid-Illinois Saturday morning, we'll likely see a few scattered showers or thunderstorms possibly lingering into Saturday afternoon. While we could certainly use a good soaker for parched lawns and gardens, most locations that receive rain should expect meager amounts staying under a quarter of an inch.

The summer heat and humidity continues to build up into next week with temperatures in the upper 80s and low 90s for the first days of September. The 6 to 10 day (9/1-9/5) and the 8 to 14 day (9/3-9/9) temperature outlooks place central Illinois in a very high probability of remaining above average. So, high temperatures should remain in the upper 80s or hotter through at least the first week and a half of September. 

THE 7-DAY TEMPERATURE OUTLOOK:  Afternoon highs will be in the low 80s Thursday and Friday; mid 80s Saturday; upper 80s Sunday and Monday; and, low 90s Tuesday and Wednesday. Overnight lows will drop to the upper 50s Thursday night; and, mid to upper 60s Friday through Tuesday night.
