St. Louis, MO — Cooler air is sweeping into the Mid-Mississippi Valley today, with temperatures expected to remain slightly below normal until Wednesday. The region will experience a dip in temperatures behind a cold front, bringing a brief taste of fall.
According to the National Weather Service in St. Louis, a high-pressure system is causing the cooler air to settle over Missouri and Illinois. However, this system will move east on Thursday, causing winds to shift south. The shift will bring warmer air back into both states, with temperatures rising into the low 80s by the end of the week.
Today’s forecast includes breezy conditions with highs ranging from 70 to 75 degrees. Wednesday promises sunny skies, but temperatures will drop overnight into the 40s. By Thursday and Friday, highs will range from 78 to 83 degrees, bringing a return to warmer weather just in time for the weekend.
