MADISON (WKOW) — Last night’s downpours and rumbles are a sign of what’s to come tonight.
But first, we’ll have to slog through another hot and humid day. Temps will reach the upper 80s by late afternoon with heat indexes touching the mid 90s. Far eastern sections might catch a stray storm due to a lake breeze, but most areas will stay dry.
Another cluster of storms is likely to form over southeast Minnesota during the early evening, then dive into southern Wisconsin overnight. A few storms could become strong to severe with hail, high winds, and torrential rain the main threats. In fact, a Flash Flood Watch is in effect tonight for Richland, Crawford, and Grant Counties.
After the storms fizzle Thursday morning, we’ll shift our focus back to the searing heat. A Heat Advisory will go into effect at noon on Thursday, lasting through 11 PM Friday. Heat indexes from 100 to 110° can be expected, and Saturday looks equally oppressive.
Another round of storms later on Saturday will signal a cooler and drier weather pattern, starting on Sunday.
