KEY MESSAGES

Updated at 1000 PM MDT Fri Sep 25 2026

- Mostly quiet weekend..slight chance of an afternoon mountain shower/thunderstorm.

- Deep tropical moisture from the remnants of Polo begins streaming into the area Monday and Tuesday, with the help of another upper level low moving over Arizona. Showers and thunderstorms with heavy rainfall potential will return.

- Skies clearing Wednesday, with a pleasant back end of the work week.

DISCUSSION

Issued at 1000 PM MDT Fri Sep 25 2026

Main moisture plume now mostly east of the CWA as the upper trough moves out over the central Plains. The tail does extend back across Hudspeth County, where enough instability persists for a few thunderstorms to move through Hudspeth and far east El Paso Counties over the next 3-5 hours. Radar is showing fairly strong storms originating near Samalayuca and now into far SE El Paso County with high reflective and MESH readings. Will have to watch for possible severe next several hours. Elsewhere a few stray storms have formed over the southern Sacs but are rapidly moving east out of the area.

Saturday and Sunday...ridging from the sub-tropical high develops over the area behind the exiting trough, bringing in mostly dry weather with suppressed cloud development. Both GFS/ECMWF show a vort center or possible MCS over the Sierra Madres of Mexico Saturday and this feature moves some moisture up late Sunday night. GFS actually brings some rain up late Sunday night to areas west of the RG Valley.

Monday and Tuesday...we await the arrival of Polo remnants Monday and Tuesday as it gradually gets absorbed by mid-latitude low sweeping into Arizona Tuesday. Latest GFS run brings the remnants across west Texas, while the ECMWF brings it a bit further west over south central New Mexico. GFS corresponds better to official NHC forecast track. Both scenarios would have some potential dangerous impacts on our area, but the ECMWF path would especially impact the entire CWA. PWs increase to around 1.4 inches with the aforementioned vort center and then as high as 1.5 to 1.6 inches Monday night and Tuesday. These kinds of PWs are around 220% of normal and likely record highs. Obviously we are looking at another round of high flood potential, though briefer than this recent event we just experienced. GFS also keeps well defined surface reflection across west Texas Tuesday afternoon for some gusty northwest winds.

Wednesday into the weekend...both GFS/ECMWF show the mid-latitude low over central or western New Mexico Wednesday afternoon. Tropical moisture is east of the area Wednesday as PWs drop to under one inch. Upper low will still provide lift and with modest instability, isolated thunderstorms are still possible. By Thursday the upper low is out over the central Plains (slightly slower in the ECMWF), with short wave ridge moving over the area. Next Pacific long wave trough moves over the Great Basin. After Wednesday we should see nice drying out with plenty of sunshine and seasonable temperatures.

AVIATION

(06Z TAFS) Issued at 1000 PM MDT Fri Sep 25 2026

VFR conditions through the period with SCT060 SCT250. Over eastern El Paso and western Hudspeth County...isolated BKN050CB TSRA until around 08Z. After 18Z increasing CU fields of SCT080-100.

FIRE WEATHER

Issued at 1231 PM MDT Fri Sep 25 2026

Fire weather concerns remain low thanks to the rain we have received over the last few days. We will have a chance for thunderstorms today, mainly in area mountains and Hudspeth county. Min RH's will be at or above 30% into the first of next week and our surface winds will be below critical levels. We will be dry this weekend, but the threat for heavy rain returns to the forecast for next Monday and Tuesday.
