Overnight a large, organized complex of thunderstorms developed over portions of Minnesota and through the night has made its way into portions of Iowa as well as Southern Wisconsin and Northern Illinois. Although not severe, a few strong thunderstorms may be possible early this morning.
As of 4:30 a.m. this complex is much less organized than before however the northern fringe may still pack a punch in some spots. Right now, very consistent lightning and heavy downpours will be the main concern as these thunderstorms move slowly east this morning. A few stronger wind gusts (40-50 mph) may also be possible in the strongest storms.
The Storm Prediction Center has kept their Marginal 1/5 severe thunderstorm risk over the state line this morning for the possibility of an isolated severe thunderstorm. Strong wind gusts continue to be the primary concern, however, as noted storms have begun a weakening trend.
The bigger story today will be the heat once again. Heat Advisories have been issued across the region lasting until 8 p.m. tonight for the possibility of head index values reaching 105°. It'll be another day of heat and humidity so heat safety will be crucial for those outside, so make sure to stay hydrated and take frequent breaks in the shade!
We could also see a bit of relief from the heat today depending on how long rain/cloud cover sticks around behind the thunderstorms this morning. But dewpoint temperatures are expected to reach the low 70's into the afternoon while any sunshine behind the morning storms will quickly increase temperatures back up into the low 90's!
