A nicer day ahead. Tomorrow will be an A+ weather day (even cooler).
I can't rule out 50s tonight or tomorrow night, as well (for lows).
July 22, 2026
Extremely high heat index values were recorded in the region yesterday.
Some of these readings are near the top of the chart for our region. Meaning they are coming close to maxing out in the highest range possible.
I can only remember a few times with numbers like these.
,
It is rare to see some of these numbers in our region. We had near-record or record-high dew points.

High heat index values from across the region. Dewpoints are susceptible to evapotranspiration from nearby fields and final values may be slightly higher than the prevailing conditions in the area. These should not be considered final/official and come from a variety of weather stations with only an initial quality control effort made so far.

We are waking up to a nicer airmass today!
I will be at a weather conference today through Sunday. I will post a few updates.
We do have another chance of thunderstorms on Friday and Saturday.
Right now, that appears to be a 30% to 50% chance. Heavy rain and lightning would be the primary concern.
THIS THREAT HAS ENDED

THIS THREAT HAS ENDED
Severe Thunderstorm Watch
A low-end severe threat this afternoon and evening. A couple of storms could produce high winds.
⚠️ The threat has ended in southern Illinois and northwest Kentucky. The northern half of southeast Missouri, as well.
The risk will end once the line passes your location.
Some areas will receive no rain or storms.
Scattered storms are likely this afternoon and evening. Mainly between 3 PM and 8 PM.
Far southeast Missouri and the Bootheel were left out of the watch. I think we should include them, as well.
A severe thunderstorm watch will be in effect for portions of southern Illinois and western Kentucky. The watch will be in effect until 10 p.m. Counties will be removed from the watch as the line of thunderstorms passes through. Thus, it won't last until 10 p.m. across a good chunk of the watch.
The Storm Prediction Center went way north with the watch. I believe the primary risk will be across extreme southern Illinois, western Kentucky, and northwest Tennessee.
I included northwest Tennessee in this alert. Fulton County, Kentucky, as well. The SPC excluded them.
The primary concern will be a couple of reports of 60 to 70 mph wind gusts and quarter-sized hail. A few larger hailstones can't be ruled out. The tornado risk is small.
Monitor your Beau Dodson Weather App. Have several ways of receiving severe weather warnings.
Don't forget www.tornadocall.com will call you if your home is inside the warning box.

If clouds are thicker today (in some counties), then you can shave a few degrees off the thermometer. Either way, it will be hot and oppressive.
Highs today will be in the 90s. Heat index values will range from 105 to 115 degrees.
Thunderstorms will develop later today. Mainly between 12 pm and 7 pm. Some will produce damaging wind and hail.
Monitor your Beau Dodson Weather App for alerts.
The chance of rain will be higher from the Missouri Bootheel into extreme southern Illinois and then into northwest Kentucky. From there southward, chances will peak.
