Rounds of scattered severe storms will be possible today, initially through the late afternoon and early evening (30% chance), increasing into the nighttime (50% chance) hours. Primary severe hazard concerns will be damaging winds and large hail with a secondary concern for tornadoes. Prepare for severe weather potential ahead of time by ensuring multiple ways to have warnings and planning for potential shelter locations.
Dangerous heat indices from 98° to 113° are expected across the local area today. An Extreme Heat Warning is in effect for much of the area from northeast Iowa, southeast Minnesota, and southwest Wisconsin as a Heat Advisory is in effect for parts of central Wisconsin.
Extreme heat indices continue into Monday with areas in northeast Iowa and southwest Wisconsin pushing 105° or more heat indices. The longer duration of extreme heat increases impacts and limits recovery, be sure to take necessary safety precautions and steps to protect yourself from extreme heat impacts.
