KEY MESSAGES

Issued at 134 PM CDT Fri Jul 31 2026

- A Heat Advisory remains in effect through 8 PM this evening as heat indices linger in the 105 to 109 degrees range areawide.

- Seasonable temps and rain chances return for our Saturday, as another cold front moves into the area. The best rain chances remain along and south of the I-20 corridor.

- Heat builds back under the upper ridging early to middle part of next week with more above average summer heat and some likely headlines once again.

DISCUSSION

Issued at 134 PM CDT Fri Jul 31 2026

Gusty SW winds are leaning into NE TX now with a good gradient ahead of our approaching cool front. The boundary is into central OK now with compressional heating still showing triple digits along the front. Timing is everything and this front will edge into our area across I-30 by daybreak and our north will see the benefits of the drier air initially, but our southern tier of Co/Pa south of I-20 may catch some of the compressional heat potential and highs again tomorrow will be warm to hot. However the NW winds will lower the RH well and will limit the potential for heat indices over 105 for areas along and north of I-20. For now with the current advisory in place areawide, we will hold off on new messaging for tomorrow. The overnight package may include partial areas south of I-20 in an advisory, or we may just see what clouds and wind can do early tomorrow and evaluate the situation mid to late morning on Saturday with an update to the forecast at that time adding an advisory if needed. The front may speed up a bit overnight as we are already coming around aloft on the winds. Our SW flow is shallow and W aloft per our 18Z sounding is appreciable and drying us out a tad with our PWAT still 1.92". The radar initiated showers right on the line of our CWA and since has moved farther to our east. The water vapor has a lobe of dry air aloft for us, but some moisture pooling along the front and we will keep a slight mention for much of this process. And this is what the models are picking up on and limiting even slightly rain chances with this front for us. Either way amounts of precip would be light, as have been expected all along this week. The RH is the kicker and will continue to improve for the balance of the weekend and even linger into next week. The models have a lobe of this arriving surface airmass at 1018mb early over NB/KN, modifying to 1013mb by Sunday over the middle MS River valley with the core center staying over the Great Lakes States. Subtle changes in pressure can bring great changes to how it feels with less RH and a nice breeze.

The upper ridge will retrograde back into the desert SW U.S., building to 600dam over AZ as the main storm track under the core low will track into the OH River Valley over the weekend and the short wave dent in the upper ridge will begin to lose ground before Monday. However, the short wave push keeps the upper ridge out over the intermountain west. Previous runs have seen the upper ridge merging with the Bermuda ridge and establishing a wide upper ridge flow, but the OH Valley, little short wave that could, keeps the Bermuda ridge out over the E. Atlantic. So the heat will return and so will the headlines, but perhaps not quite as Hot as we have endured so far. The drought unfortunately will regain much ground in the coming weeks with the CPC 8-14 day outlook keeping us above average on temps and below average on PoPs into mid August. /24/

AVIATION

(18Z TAFS) Issued at 1229 PM CDT Fri Jul 31 2026

For the 31/18z TAF update...Satellite imagery is showing a few mid to high level clouds across portions of the area with clear skies prevailing elsewhere. We could see some increase of some SCT mid deck clouds during the afternoon hours. Main change I made to this forecast period was just to add some VCSH for all terminals at different times between 01/03z to 01/15z as a cold front moves through the area from north to south. As such, northern terminals will be closer to the 01/03z and then spread southward, reaching our southern terminals by 01/15z. While there could be some reductions in flight conditions with any showers that directly impact a terminal, overall theme is that VFR conditions will prevail throughout. /33/
