Wednesday will bring a taste of fall with cooler, less humid air moving in. High temperatures will get stuck in the 70s despite abundant sunshine. If you plan on opening the windows Wednesday night, make sure you have a heavy blanket as temperatures tumble into the upper 40s to mid 50s. But the fall fling is short lived. A warming trend begins Thursday with summer heat and humidity in full effect by Friday! The weekend looks good for now with Isaac’s remnants moving into the Midwest Saturday and Sunday.
