DECATUR, IL. (WAND) - Enjoy the pleasant weather while it lasts. Central Illinois is in for a comfortable end to the week before a significant warm-up arrives early next week, bringing heat and humidity that will feel oppressive by Monday.
Friday: A Crisp, Pleasant Day
Friday morning starts crisp with temperatures in the upper 50s and low 60s — a nice early taste of fall. Patchy fog is possible during the morning commute, but don't worry; mostly sunny skies will burn it off quickly. Expect clear conditions by 9 a.m.
Temperatures will warm to the low 80s this afternoon with low humidity, making it feel refreshing and comfortable. For those heading to Friday night football games around the region, plan for temperatures in the upper 70s at kickoff. By the time games wrap up, temperatures will drop into the low 70s and upper 60s, so jackets likely won't be necessary.
Saturday: Mostly Clear Start, Clouds Increase
Saturday morning begins mostly clear with temperatures in the low 60s. Afternoon highs will reach the low to mid 80s as clouds increase throughout the day. It's another pleasant day to get outside before conditions change.
Sunday and Beyond: Heat and Humidity Return
A ridge of high pressure will push into the Midwest starting Sunday afternoon, ushering in much warmer temperatures and high humidity that will last through most of next week. This is a significant change from the comfortable weather of Friday and Saturday.
Highs will climb into the low to mid 90s starting Sunday and lasting through next Friday. The real concern arrives Monday, when feels-like temperatures will approach triple digits due to the combination of heat and humidity.
