KEY MESSAGES

Issued at 1234 AM CDT Thu Aug 27 2026

- Much needed rainfall fell late yesterday as our weak cool front began to pool all available moisture over our east.

- The surface winds will vary behind the rain, but shift to E/NE predawn for I-30 and throughout the morning southward. More showers and thunderstorms will be possible along and S of I-20 today. - The air will slowly dry out with lowering dew points as high pressure imposes on the middle and lower MS River Valley. This brief cool down will linger for days with no heat headlines.

DISCUSSION

Issued at 1234 AM CDT Thu Aug 27 2026

We should be looking at a nice break from the triple digits and heat advisory headline as a nice bubble of high pressure at 1021mb settles into the middle MS River valley and MidWest states by this time on Friday. This will knock back the humidity as dew points ease back to average expectations with NE winds for a good while in the short term period with this back door cool front.

We should see SE flow return during the coming weekend so not only is the RH going to ease a bit, but the max temperatures will get back closer to average for late August with more mid 90s for an average. The hottest temperatures will remain in our eastern Texas counties with more upper 90s. Heat index calculations will behave for the morning and early afternoon, but still peaking around 105 for maximums. And we may peak just beyond that 106 briefly in a few spots along our CWA fringe from Tyler to Lufkin and the heat headlines remain just to our west, but not all sensors are created equal and any excess should not be widespread enough to warrant a headline.

So looking better for us, but if you really want to escape the heat go north or east this weekend. Our conditions will be much improved for most of our area I am sure many will agree. The synoptic pattern has the upper ridge over AZ/NM, as expected thanks to our weak back door frontal boundary. The NE winds will keep the deeper tropical moisture to our south and the upper ridge will weaken while sliding eastward. Next week will see it push across the MS River and edge into KY/TN early next week.

This is a better scenario than building up a hefty core. The reason is the lower heights around the weakness along the Gulf coast, in the form of an inverted trough moving slowly westward. There are some brief opportunities for a sea breeze for areas south of I-20 next week in the late day, but overall the heat and drought have an easy time this year with the still high sun angle. The heat index should behave for us beyond the weekend, but likely return for us by the middle of next week. /24/

AVIATION

(12Z TAFS) Issued at 603 AM CDT Thu Aug 27 2026

For the 27/12z TAF package...it appears that all our terminals are through with precipitation, at least through this morning but did hold onto VCSH for a few more hours at the LFK terminal. We are seeing developing IFR ceilings in the wake of the large rain shield that moved through S AR and N LA overnight last night and for this reason, will have to prevail IFR ceilings at the TXK, ELD, SHV and MLU terminals through mid morning today before these ceilings scatters out. Thus VFR conditions will return to all terminals by mid to late morning and continue through the day and into the evening. Did not include this in the 12z TAF package but would not be surprised to see some patchy fog form overnight towards the tail end of this 24hr package. Look for mostly northeast winds today with speeds generally under 10kts, becoming light to near calm overnight.
