KEY MESSAGES

- Heat Advisory in effect across the entire area through Saturday. Daily highs in the middle 90s to low 100s. Maximum afternoon heat index values around 100 to 105. Minimal overnight relief with lows in the middle to upper 70s.

- Little to no rain chances over the next week, with hot and dry conditions amplifying a rapid onset drought across the area. Worsening drought conditions may allow for an early onset to the Fall fire weather season.

SHORT TERM /THROUGH TONIGHT/

Issued at 117 PM CDT Tue Sep 1 2026

Temperatures are currently sitting in the upper 90s with a nice cumulus field over most of the area. Thankfully, we have a bit more cloud cover than yesterday, which may help most of the area stay below the 100 degree mark. This is due to the slight change in air mass from yesterday. We have a bit more moisture at the 800-850mb level that has led to more cloud formation today. We can also see that evident in this morning's sounding by comparing it to yesterday's sounding. Dewpoints are a little higher than yesterday as well, sitting in the low 60s. However, temperatures outside probably don't feel any different than the previous past few days. Unfortunately the heat will continue on over the next several days.

Winds have been out of the southwest and have gusted near 15 mph today. They will turn southeasterly overnight and stay just under 10 mph. Tonight's lows will be warm in the mid 70s.

LONG TERM /WEDNESDAY THROUGH TUESDAY/

Issued at 117 PM CDT Tue Sep 1 2026

The Heat Advisory has been extended in time to include Saturday and ends at 8 PM that evening. Though, it is likely that the Advisory gets extended through Labor Day Weekend due to the longevity of the heat and warm overnight temperatures in the 70s. This heat isn't expected to end anytime soon. The reason why we haven't upgraded to an Extreme Heat Warning is because of the uncertainty in daily heat index values. Guidance is hinting at a drier air mass moving into the area for the weekend which would impact our heat index values. The past few afternoons have trended drier than model guidance with the exception of today due to the small bit of moisture that has moved into the area. With that in mind, this may keep our heat index values below Extreme Heat Warning criteria (HI of 110 degrees). Though, it won't change the fact of it'll still feel hot if you're participating in any outdoor activities this weekend. Remember the rest of the week into the weekend will feature a Major to Extreme HeatRisk across our area. Be sure to hydrate and take breaks from the heat this weekend, especially with no overnight relief.

Very low-end POPs of 15-30% move into the area on Sunday as a weak front is forecast to move through. However, temperatures won't change much to start next week with highs still in the 90s.

AVIATION /00Z TAFS THROUGH 00Z THURSDAY/
