Get ready for a Spring chill. Thanks to clear skies and light winds, temperatures overnight Sunday into Monday will drop into the mid to upper 40°s in many spots, and near 50° in metro St. Louis. The entire week ahead will be a cooler one. After a sunny start Monday, clouds increase. Highs will be in the mid to upper 70°s. We’ll see several waves of rain and storms Monday night and Tuesday and again on Wednesday. Cooler both days with highs near 70° Tuesday and in the mid 60°s Wednesday. A break from the wet weather Thursday with more storms possible Friday.- Angela Hutti @AngWxGrl
