Not as excessively hot today, though humid conditions linger

Last night's widespread rainfall was welcomed with open arms considering we haven't seen anything over 0.10" since August 16th. Most across northern Illinois wound up with .15" to .25", with higher rainfall totals observed to our south and east. 

Big day ahead for RPS 205 students as the new school year gets underway. Thankfully, conditions will be fairly quiet throughout the day, though an isolated passing shower or thunderstorm cannot be ruled out. Despite a cold front coming through overnight, it will still be a very warm and muggy, though not to the extent of Tuesday. Afternoon highs should peak in the mid to upper 80s, with heat indices ending up near the 90° mark.

Thursday will be very similar to Wednesday, with afternoon highs reaching the upper 80s under mainly dry conditions. A stronger cold front will enter the equation Thursday night into Friday morning, bringing with it a much more organized chance for widespread clusters of showers and storms. While severe weather potential is low, heavy rainfall and sporadic wind gusts will be possible. 

 

Temperatures following this frontal passage will fall back into the low 80s for Friday and Saturday. A third cold front is shown sliding through Sunday, allowing a stronger push of cooler air to occur into the Great Lakes. Expect highs early next week to land in the low to mid 70s, which is a whopping 18° to 22° cooler than highs the last two days. Along with the cooler temperatures will come generally tranquil conditions as multiple high pressure systems slide into the Midwest and Great Lakes.
