NWS El Paso, TX wrote its last area forecast discussion before the first event at Jul 31, 10:56 AM MST, 1 hour 34 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service El Paso TX/Santa Teresa NM 1156 AM MDT Thu Jul 31 2025 ...New DISCUSSION, AVIATION, FIRE WEATHER... .KEY MESSAGES... Updated at 1156 AM MDT Thu Jul 31 2025 - Decreasing moisture will lead to lower coverage and low flash flood potential through the weekend. Isolated thunderstorms each day but mainly over the mountains. - Temperatures will gradually warm through this same period with lowland high temperatures into the triple digits Saturday and beyond. && .DISCUSSION... Issued at 1156 AM MDT Thu Jul 31 2025 At upper levels, mid-latitude flow is trying to sneak in with drier southwest flow. At mid and upper levels, NA monsoon high is gradually repositioning over Arizona and New Mexico over the next 2-3 days. This will slowly transition us from the wet pattern of the recent past, to a drier, hotter pattern. In the short term, what's left of the moisture plume persists over most of the CWA this morning. PWs range from 1.2 inches west to 1.0 inches or lower east. A weak disturbance aloft along the back edge of the moisture plume has kept a few thunderstorms going over eastern Grant and western Sierra Counties this morning. These should end next couple of hours--same time as the new convection starts forming over the mountain zones. Today looks to be the last day where the entire CWA has at least a slight chance of rain. High-res models do show some favor for higher POPs over the mountains and west of the RG Valley with slightly higher PWs and instability. PWs still running a bit above so some heavy rain/flood potential continue today. HRRR shows outflow coming out of the Tularosa Basin around 00-02Z so this could help the eastern lowlands produce a few storms. HRRR also shows Gila storm outflow reaching the Lordsburg Playa area with 35 mph gusts, but not until around 04-06Z. Will have to watch for more blowing dust in that area. Friday and Saturday...continue decreasing storm coverage and attendant flood potential. Slightly higher instability/moisture exist over the mountains and west of Deming favor those areas with isolated storms, while POPs begin phasing out other areas. Temperatures will start to warm above normal, and lowlands by Saturday will start to see some triple digits. Sunday through Wednesday...mid/upper level NA monsoon high is in place over Arizona and New Mexico. 500mb temps warm a bit helping to cap the atmosphere at mid-levels, so only chance of rain likely limited to the mountain zones, and during daylight hours. Main tropical moisture remains south and west of the high center, well out of our forecast area. Temperatures will be the main story, as most of the lowlands into triple digits. Latest NBM high temps show some of the lowlands just shy or at Heat Advisory criteria Sunday through Wednesday, but 75th and 90th percentiles push those areas into the Advisory criteria--those areas mainly being Luna, Dona Ana, srn Otero, and El Paso Counties along with the lower valley of Hudspeth County. && .AVIATION... (18Z TAFS) Issued at 1156 AM MDT Thu Jul 31 2025 VFR conditions expected through the period with SCT100 SCT250. Scattered BKN060CB -TSRA developing over the east slopes of the Sacramento Mtns. Storms will also form over the Gila/Black Range but around 20Z as current cloud cover will inhibit convection. Rest of lowlands will see isolated, disorganized thunderstorms beginning around 21Z. Some models show more organized storms moving out of the Gila/Black Range and into Sierra, Luna, and Dona Ana Counties. This could impact KTCS, KDMN, and KLRU TAFs after 03Z. Thunderstorms could produce pea-size hail and wind gusts of 30-40 knots. && .FIRE WEATHER... Issued at 1156 AM MDT Thu Jul 31 2025 Low fire weather concerns through Saturday. Thunderstorm coverage becoming less through this time, mainly over the mountains and Deming west. Still some flood potential for the burn scars this afternoon/tonight, but this threat should also decrease through Saturday. Sunday and beyond will see much warmer temperatures and just a slight chance of daytime mountain thunderstorms. Temperatures will climb to well above normal. Lowland min humidities will fall back to near critical levels, while the mountains remain above. Fortunately no significant non- thunderstorm winds are expected with the lowered humidity. Min RH: Lowlands 20-28% through Saturday, decreasing 10-17% Sunday through Tuesday. Gila/Black Range Mtns...25-40% through Saturday, decreasing to 15-25% Sunday through Tuesday. Sacramento Mtns...45-55% through Saturday, decreasing to 20-30% Sunday through Tuesday. Vent rates poor-fair through Saturday, then good-very good Sunday through Tuesday. && .PRELIMINARY POINT TEMPS/POPS...
