DISCUSSION

Issued at 1058 AM MDT Wed Jul 29 2026

Dry, stable air over the eastern two-thirds of the CWA and upper high in NE NM will inhibit storms over the lowlands late this afternoon and into the evening. A storm or 2 could form over the Sacs but will have a hard time making it off of them. Looks like a repeat of yesterday out west where widely scattered to scattered storms will develop by mid afternoon and move out of the area in the early evening. Expect another mild night with most lows in the 70s/60s mountains. Little change in the pattern for Thu with high temps over the lowlands reaching 102-107. NBM temps looked a degree or two low and did raise up, especially along RGV to line up with the ongoing Heat Advisory.

Going into Fri, the upper high strengthens as it retrogrades into eastern AZ. GFS showing near a 600dm high developing. H85 temps over the lowlands getting into the 36-37C range support highs of 105-110 for most of the lowlands. Thinking the Heat Advisory will need to be expanded in coverage for Fri afternoon. Again did raise highs from NBM, closer to the MAV which came in with 109 for ELP and 106 for LRU. Didn't go quite that hot at ELP, but it's not out of the question. As the upper high shifts west, we start to get a return of some moisture coming around the ridge. Thunderstorm chances will spread across most of the area Fri with generally low scattered coverage for the lowlands going into the evening. Saturday is looking like the most interesting day with best moisture and instability around. Scattered lowland to numerous storm coverage in the mountains is expected. This far out, I did lower NBM PoPs a little bit from the 80s in the Sacs and went with 60-70%. With the NE flow and GFS showing LI's of -4 to -5C over the east, could see a few severe storms. Temperatures will cool down a little bit here with highs closer to 100 for the lowlands.

More stable air moves in for Sunday with storm coverage back to staying out west with temps another couple degrees cooler than Sat. The upper high weakens over AZ for early next week with daily disturbances moving around the high and bringing mountain storms which will push outflows onto the lowlands and isolated thunderstorm coverage. Temps will start to rebound a bit but look to stay below advisory criteria.

AVIATION

(18Z TAFS) Issued at 1058 AM MDT Wed Jul 29 2026

P6SM FEW-SCT100-120 with isolated to low end scattered 3-5SM TSRA developing over far western NM and the Gila region by 20Z and pushing out of the area by 02Z. Outflow winds of over 30KTS could affect KDMN and KTCS but storms will stay out of these terminals. Winds generally east to southeast AOB 12KTS but turning W to SW from KDMN west after 00Z.

FIRE WEATHER

Issued at 1058 AM MDT Wed Jul 29 2026

The next couple of days will be close to the hottest of the summer as the lowlands will be in the 103-108 range. RH's will remain above 10 percent for the lowlands and mainly in the upper teens and 20s for the mountains. Storm coverage the next couple of days will be a little less than recent days, but at least isolated coverage is expected. The upper ridge currently over NM shifts into AZ by the weekend and brings a return to the pattern similar to a week or two ago with northeast flow helping storms develop over the higher terrain and moving onto the lowlands starting Friday and especially Saturday areawide. Some of these storms will be capable of locally heavy rain and some gusty winds/hail. Temperatures will cool down to near 100 for the lowlands by the weekend with RH's on the rise. Sunday looks drier before daily storm chances return for early next week.
