KEY MESSAGES

Updated at 345 AM CDT Mon Jul 27 2026

- Heat Advisories are in effect from noon MDT /1 PM CDT/ Monday to 8 PM MDT /9 PM CDT/ Tuesday for the Eddy and Reeves County Plains, eastern Culberson County, Loving and Ward Counties, and the Davis, Guadalupe, Chinati, and Delaware Mountains.

- Temperatures this week will climb into the triple digits most locations each afternoon. Additional Heat Advisories are likely, as the effects of heat are cumulative, and present an increasing risk of heat-related illnesses. - Rain chances will be slim to none.

SHORT TERM

(Today through Tuesday afternoon) Issued at 345 AM CDT Mon Jul 27 2026

Persistence sets in today, with WV imagery showing the upper ridge parked over northeastern New Mexico and the Panhandles. Model Certainty suggests today will be the warmest day this forecast, with highs topping out 8-10 F above climatology. Very warm temperatures are expected in the upper Pecos River Valley, and Heat Advisories are in effect as a result. Latest NBM suggests the Davis, Guadalupe, Chinati, and Delaware Mountains will meet criteria, so we've issued advisories for them, as well.

Overnight minimums will remain unseasonably warm, ~ 6-8 F above normal due to a recurring LLJ and a few high clouds to retard radiational cooling. Unfortunately, there's no reason to expect much variation in these warmer temperatures through the extended.

Tuesday, the upper ridge is forecast to move very little from where it is today, with highs likewise looking nearly identical to what's expected today. That said, considering the unseasonably warm temperatures expected tonight, and that heat effects effects are cumulative, we see no reason not to extend today's advisories through Tuesday evening.

Unfortunately, short term grids remain dry.

LONG TERM

(Tuesday night through Sunday) Issued at 345 AM CDT Mon Jul 27 2026

About the only thing to look forward to in the long term is that the LREF and global models are all in agreement in slowly meandering the upper ridge west through the weekend, to the vicinity of the Four Corners. This will decrease thicknesses a little, offering some relief from highs the next couple of days as we approach KMAF's climatological peak of temperatures for the year. Additional Heat Advisories may be warranted after Tuesday. Toward the weekend, the ridge may be far enough west that isolated convection may creep back into the mix, mainly Southeast New Mexico and the higher terrain of West Texas. But chances will be minimal at best.

AVIATION

(12Z TAFS) Issued at 345 AM CDT Mon Jul 27 2026

VFR conditions will continue next 24 hours in light return flow, with a high cloud or two. Convective chances are nil, but a cu field is anticipated all terminals except KMAF and KINK, where convective temps are too high.
