Temperatures a tad cooler Saturday--highs nearing the mid to upper 70s. Though, the humidity won’t make it feel any cooler. Dew points rising near the 70s.

Round 2 Saturday evening into the overnight hours early Sunday as the warm front continues to lift north through the central WI region bringing heavy rainfall amounts near two inches. This setup could be favorable for strong to severe storms. However, showers from round 1 and overcast skies during daybreak look to limit severity.
