Sunday is our next First Alert Weather Day. There will be plenty of clouds with rounds of showers and storms throughout the day tomorrow. Humidity spikes again, too, so any downpours will be capable of brief heavy rain. Localized spots of flash flooding are certainly possible wherever the heaviest cells move through.

The heat is building across the Upper Midwest for the end of the weekend and start of the new work week. High temperatures Sunday and Monday could be into the low 90s, while the feel like temps could rise into the mid 90s to mid 100s.
