KEY MESSAGES

Issued at 1230 AM CDT Sun Sep 13 2026

- Late summer heat continues unabated with more heat advisories likely beyond today through much of this upcoming week.

- Rain chances will be largely negligible throughout the week as well with only very isolated afternoon convection due to the influence of the dominant upper ridge.

- The ridge is expected to migrate back westward and further retrograde W/SW by late next weekend, paving the way for a cold front to make its way south into our region.

DISCUSSION

Although the calendar suggests temperatures should be trending cooler by this point in September, that isn't the case for now. The unrelenting heat will be with us for the duration of this upcoming week due to the upper ridge that simply refuses to give up the ghost. At this point, we're just as tired of writing about it as the rest of you are of reading about it. So for this last full week of summer, just know that it will very much continue to feel like it and then some. Heat safety reminders should still be exercised throughout this week with all outdoor activities and especially youth sports with daily high temperatures in the upper 90s to lower 100s.

Adding to the heat concerns, a lack of appreciable rainfall will also continue to exacerbate the ongoing drought conditions and wildfire danger. Fortunately, wind speeds are expected to remain light throughout the week while afternoon relative humidity isn't expected to bottom out too low given that dew points are expected to hold in the lower to mid 70s. Of course, the counter to that is the additional impact on heat concerns with heat index values from 105-109 degrees with less mixing out of low-level moisture during the afternoon.

Looking out beyond this upcoming week, medium-range guidance does continue to point toward an eventual pattern shift beyond this forecast period. However, the caveat is there just isn't enough confidence yet to say exactly what that pattern change will bring in terms of heat relief and improving rain chances. For now, NBM guidance continues to trend slightly lower with temperatures by next weekend with a cold front attempting to make a run southward into our region. So maybe, just maybe we're starting to see some light at the end of this long tunnel we call Summer in the South.

AVIATION

(12Z TAFS) Issued at 631 AM CDT Sun Sep 13 2026

For the 13/12z TAF update...Radar imagery remains quiet this morning, but that should change as we move into the afternoon hours as some isolated convection will develop. I don't think that any terminals will see a direct impact from any thunderstorms, but I have left mention of VCTS for all terminals this afternoon. While winds will be light throughout this period, there is some potential that winds could be gusty and erratic at times from any outflow boundaries that develop from thunderstorms. /33/
