Hot conditions and storm chances continue

Wednesday will be another hot and humid day out there.  A Heat Advisory will be in effect from 11am until 10pm across most of Illinois and southern Wisconsin as a warm front lifts northeast over the area.  Temperatures will start out in the 70s during the early morning hours, but will quickly rise going into the afternoon, reaching near or just over 100 degrees.  The heat index is expected to reach into the 100-110 degree range.

After the warm front lifts northeast over the area, we will be watching a cold front out to our west start to push east towards the stateline as the area of low pressure moves across southern Minnesota and central Wisconsin.  This will bring another chance of rain/thunderstorms going into Wednesday evening and overnight into Thursday.  The front should clear out of the area by Thursday afternoon, which means the chance of storms could last through Thursday morning before the skies begin to clear out heading into the weekend.


Taking a look at the convective outlook put out by the Storm Prediction Center, some of the storms late this afternoon and through the late evening hours could be on the strong to severe side, as we are in a slight risk area for severe weather.  The biggest threats from these storms would be heavy rains, strong winds, and possible hail.  The risk of severe weather will be reduced going into Thursday morning as the cold front passes through the area late Wednesday night.  The chance of storms will be reduced heading into weekend as high pressure moves into the region on Saturday.
