The record warmth invaded Minnesota and Iowa on Monday. Highs reached the upper 80s and even the lower 90s for highs Monday afternoon. Austin, Winona, and La Crosse all reached 90° for the high temperature.
Rochester set the daily high-temperature record for September 30th hitting 88° beating the previous record of 86° set back in 2002. Cooler conditions are back in the forecast for the rest of the week.
But before the cooler weather comes, we’ll have a chance for some isolated strong to severe thunderstorms Monday night into Tuesday morning. Some of these storms could have gusty winds and large hail. Storms should remain isolated through the late evening hours mainly after 8-9 pm on Monday evening.
Showers and thunderstorms will continue to impact the forecast on Tuesday and Wednesday. Heavy rain is expected through the daytime hours on Tuesday. A Flash Flood Watch has been issued for most of the area south of Highway 14. This does include Rochester and Olmsted County.
Rainfall accumulations Tuesday and Wednesday could reach near 2-4″ of rain. Continuing to add to our precipitation total for the year.
Temperatures return to “fall-like” for the rest of the week. Highs Tuesday will be in the lower 60s and upper 50s. Then temperatures will be in the middle and lower 50s through the rest of the workweek.
