Updated at 1147 PM MDT Fri Jul 4 2025 - Temperatures climb through Sunday before decreasing some early next week, then back up mid to late next week - Moisture slowly recovers on Sunday, bringing isolated to scattered thunderstorm chances, especially west && .DISCUSSION... Issued at 1029 PM MDT Fri Jul 4 2025 The drying trend will become very apparent as an upper trough over eastern AZ sweeps through overnight tonight, cutting off our monsoonal moisture supply. PWATs are expected to decrease significantly, leading to lower Tds and reduced instability. As the upper high establishes itself over NM, thunderstorm chances will become very limited, mainly confined to the mountains. A backdoor front sliding down the eastern plains will help to invigorate lift with moist upslope flow, allowing isolated afternoon storms to initiate over the south central mts. 500mb temps remain relatively warm, however, hovering around -5C. Storms will struggle in this environment and what ones do develop will likely remain weak and short-lived. With clear skies and very warm 850mb temperatures, much of the lowlands can expect to see triple-digit highs. Expect highs in El Paso to reach around 100F to 102F. High pressure will continue to dominate the weather pattern on Sunday, resulting in another hot and dry day. Thunderstorm chances will remain very low, primarily favoring to the higher elevations of the Sacramento Mts once again. Temperatures will be similar to Saturday, with widespread triple-digit heat for the El Paso metro and surrounding lowlands, potentially reaching up to 102F in some areas. The upper high will drift slightly towards the AZ/NM border on Monday. This subtle shift may allow for a very slight increase in mid-level moisture, primarily from the east/northeast. While not leading to widespread storm coverage, isolated afternoon thunderstorms cannot be entirely ruled out, particularly over the mountains and possibly some eastern parts of the CWA. Temperatures will remain well above normal, generally in the upper 90s to low 100s for the lowlands. As the high continues to slowly weaken and shift, mid-level easterly to northeasterly flow will persist, potentially bringing in a bit more moisture. This pattern, while not ideal for extensive monsoon activity, could support isolated to scattered thunderstorms Tuesday through Thursday. Temperatures will begin to moderate slightly but will still be very warm. && .AVIATION... (06Z TAFS) Issued at 1147 PM MDT Fri Jul 4 2025 Light and vrb winds overnight giving way to typical aftn breezes aft 05/18Z with gusts generally under 20 kts.

Issued at 1045 AM MDT Fri Jul 4 2025 Warming temperatures and lower dew points will lead to a decrease in min RH values, with much of the lowlands falling below 15% for tomorrow and Sunday afternoon. Rain/storm chances will all but disappear except across the Bootheel. Winds will remain light, however, topping out around 10 MPH. As we go into Sunday, moisture begins to increase again leading to scattered mountain and isolated to scattered lowland storms. Rain/storm chances will favor areas west of the Divide. Vent categories will range fair to very good each afternoon, largely limited by weak transport winds courtesy of high pressure aloft. && .PRELIMINARY POINT TEMPS/POPS...
