Through Thursday night…

A broad surface high continues to reside across the Ohio River Valley which has kept our skies cloud-free Wednesday afternoon. The abundant sunshine has helped temperatures to warm into the mid to upper 20s this afternoon with a chance that some areas may see another degree or two of warmth before all is said and done.

An area of cirrus clouds continues to be observed across central and southern Illinois this afternoon with recent satellite trends showing these clouds are starting to drift northwards towards our area. While it looks like the thickest of these clouds would remain across the southern portions of our forecast area, the increasing cloud cover this evening should help to limit the radiational cooling tonight and keep temperatures in the low to mid teens for most areas with some locations under the thicker cloud cover seeing values in the upper teens. The clouds are expected to diminish heading into Thursday morning which will allow for another mostly sunny afternoon which in combination with increasing southwesterly winds should allow temperatures to climb into the upper 20s to mid-30s for most locations, although areas across far northern Illinois may still struggle to get out of the 20s due to the snow pack.

The seasonable temperatures will be brief as an arctic front is expected to swing through northeastern Illinois and northwest Indiana late Thursday afternoon into Friday morning. While the frontal passage continues to look dry, winds will become northwesterly and increase in speed as a tightening pressure gradient (6 to 7 mb increase in 6 hours) develops behind the front. The cold arctic air will send temperatures plummeting into the low single digits to near zero with areas across northern Illinois seeing lows in the negatives. These temperatures in combination with the increasing northwest winds will create wind chills in the -15 to -25 degree range for Friday morning. Wind chills of this magnitude are capable of causing frost bite in less than 30 minutes so be sure to bundle up before heading out Friday morning. If this trend continues a Wind Chill Advisory may be needed with future updates.
