Mother Nature has saved the hottest day of this workweek for last.
After highs in the lower to middle 90s all week, we’re headed for upper 90s Friday.
Before that happens, though, we’re in for another humid night.
Widely scattered showers and thunderstorms will be seen Thursday evening and early Friday morning, with an isolated strong or severe storm possible. Of course, any rain that these storms produce will be most welcome, since drought conditions are getting worse.
Otherwise, look for mostly cloudy skies and evening temperatures in the 70s and 80s followed by an overnight low of 75.
A HEAT ADVISORY is in effect again tomorrow for most of Siouxland, including Sioux City. Locations to the south (Missouri Valley, Tekamah, Fremont, Omaha/Council Bluffs) will have an EXCESSIVE HEAT WARNING again tomorrow.
Look for a high of 99 Friday. Add in the still-strong humidity, and we’re looking at heat index values over 100 in the afternoon and early evening, when another round of scattered showers and storms may develop after 7 PM. These showers and storms would be finished before sunrise Saturday.
The weekend looks slightly cooler, with 91 the high Saturday and Sunday, and it will be somewhat less humid.
We’ll cool a bit more early next workweek, to the upper 80s for highs Monday through Wednesday.
Bad news: The heat and humidity will be back by late next week. Thursday’s high will be 92.
Keep staying cool!
