Tonight and Wednesday...

High pressure continues to prevail over the region, keeping us warm and dry. Temperatures generally reached the upper 80s and low 90s Tuesday afternoon. Lows tonight will fall into the mid and upper 60s. Patchy fog will once again be possible across parts of the forecast area, especially in low lying areas, where crossover temperatures are reached and winds diminish.

Any fog that does develop should burn off shortly after sunrise Wednesday. Highs will be similar to the last few days, in the upper 80s and low 90s.

Friday and Beyond...

Temperatures continue to ramp up as we head into the latter half of the week. Highs are expected to reach the mid to upper 90s by Friday and Saturday, with several locations potentially reaching 100 on Sunday. While not overly extreme, dewpoints have continued to trend slightly higher than guidance recently. If this continues through the weekend, heat indices may reach 100-105. Meanwhile, overnight lows are forecast to remain in the lower 70s, providing little relief from the daytime heat. While certainly not a slam dunk, heat headlines may need to be considered for Friday through Sunday.

A low pressure system moving out of Canada toward the Great Lakes will work to flatten the upper ridge late this weekend. While better precipitation chances will unfortunately skirt the forecast area, this system will drag a cold front through the Central Plains, bringing us some relief from the heat.

Behind the front, northwesterly upper level flow appears to return. If this remains the case, we could see a few short waves rounding the ridge and bringing precipitation chances back to the region.

AVIATION /06Z TAFS THROUGH 06Z THURSDAY/

Issued at 1204 AM CDT Wed Jul 15 2026

VFR conditions continue to prevail. Light winds and mostly clear skies are anticipated tonight. Very patchy morning fog is expected, but aviation impacts are unlikely. Southeast winds and a few cumulus around FL070-080 develop by Wednesday afternoon.
