Storms today, chilly fall air invades next
Plenty of moisture and warm air will be left over around a frontal boundary lifting northward today. This will lead to showers and thunderstorms as we head into the late morning and afternoon hours. Most of the activity will end by this evening and early part of the night. A few storms that develop could be strong with wind, hail, and heavy downpours. The SPC has a marginal risk of severe weather for southeastern Wisconsin today. Make sure you have ways of getting weather information. A Flood Watch remains in play for the western and central part of the state.
On the western side of this storm system is cold air and snow. There are Winter Weather Advisories for parts of Minnesota, the Dakotas, and Nebraska today where they could see a few inches of snowfall. Chilly air invades the region behind the cold front the rest of the week. Highs will fall into the 40s and 50s while overnight lows plunge into the 30s. Fall is officially upon us!
