Strong thunderstorms will push through Sunday late afternoon and evening. Those storms will produce heavy rain and lots of lightning, with potential for some strong wind gusts, small hail, and a small chance for an isolated tornado. Stay weather aware this evening. Quieter weather arrives overnight, it stays warm with lows near 70 and lots of humidity.
Monday morning a decaying line of showers and storms will be moving from NW WI toward SE WI, but it's questionable how much of this line holds together, and therefore what impacts we see. At this point, looks like a few scattered showers or storms for the morning. Then, in the afternoon, a complex of storms will develop in Iowa. Some solutions show this complex moving across the southern half of our area, others have it staying south of the state line, and we stay dry. It will be a wait and see but heads up that there may be a few afternoon storms. Outside of any rain and storms, it will be a very hot and humid day. Highs top out in the upper 80s, with dewpoints in the 70s, it will likely feel like temperatures are in the low 90s. Winds will be breezy from the SW, gusting up to 30 mph.
High pressure builds in for the rest of the week, bringing sunny skies, drier air and highs in the mid 70s to near 80°.
