KEY MESSAGES

Updated at 345 AM CDT Tue Jul 28 2026

- After today, temperatures will cool a degree or two into next week, still climbing 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. - There will be a slight chance for rain along with a weak cold front this weekend.

SHORT TERM

(Today through Wednesday afternoon) Issued at 345 AM CDT Tue Jul 28 2026

Persistence continues today, with WV imagery showing the upper ridge parked over northeastern New Mexico and the Panhandles. This is where it was 24 hours ago, so it's no surprise that today's highs will be very similar to yesterday's. Therefore, the current Heat Advisories will continue through early early evening, with the addition of the Chisos Basin, where it looks to be a couple of degrees warmer than what was portended 24 hours ago. To those who prefer cooler weather, today appears to be the warmest day this forecast.

Tonight, unseasonably warm overnight minimums continue, mainly due to a recurring LLJ every night, occasionally assisted by mid/high clouds to retard radiational cooling. Overnight lows will come in ~ 6-8 F above climatology. Unfortunately, there's no end in sight to these warmer temperatures.

Wednesday, the ridge weakens a little, decreasing thicknesses and shaving a couple of degrees off highs, which should top out ~ 6-8 F above normal. These highs may be low enough to negate the need for heat advisories, but the Davis Mountains may need one, especially if current forecast highs increase.

Unfortunately, short term grids remain dry.

LONG TERM

(Wednesday night through Monday) Issued at 345 AM CDT Tue Jul 28 2026

In the extended, the upper ridge is still forecast to meander west into next week, with the LREF and global models in agreement in taking it southwest of the Four Corners by Friday morning. This will precipitate a decrease in thicknesses a little, offering some (but not much) relief from the warm weather of the past few days, even if KMAF's peak climatological annual heating is only a couple of days away. Heat Advisories may still be needed to some extent or another each day beginning around Friday or so. 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. Models try to bring a very weak cold front into the area Saturday, which may kick off a little convection Saturday evening. But rain chances will be minimal at best.
