Residents of far northeast IL including Chicago & far northwest IN know that milder spring-like days inland can often mean lake breezes with falling afternoon temperatures for their location. Such will be the case today as shown in this forecast temperature animation. #ilwx #inwx pic.twitter.com/1TVA3tOPql
