KEY MESSAGES

Updated at 1030 PM MDT Thu Sep 3 2026

- Friday and Saturday will see continued isolated to scattered storm chances before pushing mainly west of the Continental Divide by Sunday.

- The main threat with any storms will be locally heavy rain and flooding with plenty of moisture in place and slow storm motion.

- Temperatures will remain above normal with 90s for the lowlands into early next week.

DISCUSSION

Issued at 1030 PM MDT Thu Sep 3 2026

Models through the weekend are is good agreement with the upper high shifting westward and ending up in the KS/OK border region with a ridge axis cutting through the CWA. Currently we have some of the highest PW's of the monsoon season in place with 1.4" on 00Z EPZ sounding. With pretty weak flow over the area, this moisture remains in place through Sat. The issue will be a little subsidence inversion showing up on forecast soundings around 400-500mb and that ridge axis.

There will be an MCV developing overnight and bringing some showers and a few thunderstorms to the CWA. Looks like most precip should be over by sunrise Fri, but there will be residual cloud cover at least through the morning which will likely limit heating somewhat into the afternoon. As happened today, these morning clouds could limit afternoon storms as well. GFS and CAMs are keeping coverage pretty limited and over the northern and eastern areas. EC is a little more aggressive with storms continuing into the RGV and far west TX after 00Z. There is agreement there will be some LL convergence over Hudspeth around 00Z which could send outflows further west and trigger additional storms. Previous forecast seems to cover this pretty well and will not stray too far from that. High temperatures will continue to be warm with mid 80s to mid 90s for the lowlands depending on cloud cover.

A similar pattern for Sat, except there is a better low level wind flow for storms to develop over the Sacs and then outflows pushing storms onto the lowlands. The ridge axis and subsidence inversion will limit storm coverage but at least isolated(20%) coverage looks warranted for eastern areas. temperatures look similar to Fri.

For Sun/Mon, the ridge axis pushes a little further west and starts to bring in some drier air to eastern areas. Expect most storm coverage here to be focused west of the Continental Divide. These also look like the warmest days with some areas approaching 100 in the lowest elevations on Sunday.

Tue-Thu of next week we are seeing some differences in the models. The EC keeps upper high the dominant weather feature over the area while the GFS has the high further east and allows a weakness in the upper flow to move in from Mexico. Ensemble means of both are more similar and the upper weakness shown on the operational GFS is not as noticeable in it's mean. There will be a nice ESE flow pattern though, which will bring a return to some better moisture, so will keep NBM low end PoPs going with temps remaining on a very slow downward trend.

AVIATION

(00Z TAFS) Issued at 1030 PM MDT Thu Sep 3 2026

P6SM SCT-BKN090-110 BKN150-200 with scattered showers and a few thunderstorms moving north around the Luna/Dona Ana Co line and then another area along the RGV in far west TX. Storms are struggling to make it to any terminals but included some PROB30 for KDMN early on and just VCSH at KLRU and KELP. Expect light scattered showers to continue through the night but be on the light side. Cloud cover will gradually start to break up during the afternoon, but these clouds will likely limit convection during the afternoon with mainly northern and eastern areas seeing storms between 20-00Z with a few storms pushing onto the lowlands after 00Z.

FIRE WEATHER

Issued at 1030 PM MDT Thu Sep 3 2026

Good moisture remains in place over the area and there will be off and on storm chances over the next week. RH's across the lowlands through the period will remain in the 20s with 30s/40s in the mountains. Upper ridge axis will remain over the region as well which will keep winds on the light side, so overall fire danger will be low.
