We have some thunderstorms moving through the region this morning. Those should come to an end later this morning and the clouds will start to break. It will be a little cooler and a little less humid today. Highs should top out in the upper 80s to right around 90. Another round of showers and thunderstorms will be possible later this evening and last into the overnight hours.
The heat and humidity will surge back into the Sioux Empire Wednesday. An Excessive Heat Watch is set to go into effect Wednesday afternoon and last through Friday evening for southern parts of the region. Heat indices over that stretch could approach 105 for some with actual highs in the 90s for most. There's also another chance of a few thunderstorms Wednesday evening and Wednesday night. We'll dry out and warm up for Thursday. Temperatures will approach the mid 90s for some with heat index values in the triple digits.
We'll slowly start to cool off heading into the weekend. Highs Friday and Saturday should fall into the low 90s. Many of us should be in the low to mid 80s by Sunday and Monday. Other than a couple chances of isolated thunderstorms Saturday night, it looks like we should be staying mostly dry.
