Updated at 525 PM MDT Tue Oct 7 2025 - Temperatures remain a few degrees above normal through Saturday before cooling down going into early next week. - Increasing chance of showers and thunderstorms through Wednesday with some locally heavy rain possible, favoring northern and eastern areas. - Drier conditions Thursday through Friday, trending back up Sunday into Tuesday with some remnant tropical moisture trying to move into the area. && .DISCUSSION... Issued at 1212 AM MDT Tue Oct 7 2025 A fairly stagnant pattern, especially early on with a trough over the eastern US, a ridge central and a trough west. This will slowly progress eastward going into next week, but for the Borderland, this will lead to a general southwest upper level flow. There was an initial push of cooler/moist air last night that made it to the RGV but has since started to make it to the AZ border. Moisture over the area is above normal with PW`s getting into the 1"-1.25" range over much of the next 7 days. Tonight and Wed, there will be some instability and some disturbances moving out of Mexico across the area that will trigger showers and thunderstorms. Seeing some convergence over the RGV area around H70 this evening and this may be the focus for development which will then push NE. Could see some locally heavy rain if training develops as well as a couple stronger cells with good shear over the area. Looks like the main timeframe will be tonight, but some storms will linger over the north and west tomorrow. Mostly cloudy skies and higher dew points across the region will keep lows warmer than the last several days, especially west and north where the moisture push just moved in. Highs tomorrow will be highly dependent on cloud cover, MET Guidance is more bullish on keeping clouds around and cooler temps while the MAV and NBM are much warmer. Going to expect some effect from the cloud cover and went below NBM/MAV but above MET. One issue that we will have for the next several days will be a persistent east-southeast wind. This will be most pronounced on western mountain slopes and especially out in Hidalgo and southern Grant counties. This is a pattern that will usually bring winds of 15-30 mph with higher gusts on the Lordsburg Playa, so we may need to monitor for some patchy dust. Upper ridge will prevail and keep the area dry for Thu/Fri with temperatures warming into the 80s for most of the lowlands. During this time, Hurricane Priscilla will be moving NNW and get caught up in the southwest flow ahead of trough off the west coast. It looks like most of the tropical moisture will move north of the area, but we will see some precip return starting Saturday with the breakdown of the upper ridge. The question then becomes how the next tropical system, possibly Raymond, will move. The GFS is much slower with this while the EC is the faster solution. Either way, some of this moisture looks like it will move over the area. GFS takes it`s time bringing it through and puts out 1-2" of rain for much of the area Sun-Tue. At this time it`s too early to have high confidence in the speed this storm will move, so will keep at least chance PoPs going into early next week with cooler temperatures. && .AVIATION... (00Z TAFS) Issued at 525 PM MDT Tue Oct 7 2025 A line of thunderstorms is developing N-S near KLRU to begin the period behind a slow-moving outflow boundary that`s pushing west towards KDMN. TS are most likely to impact KLRU this evening with lower confidence for the other terminals. Radar trends will be monitored for possible amendments, but all TAF sites have a mention of VCSH or VCTS. Storms will be capable of producing gusts to 30kts, small hail, and heavy rain. The convection is expected to mostly dissipate overnight, but there is a low chance of redevelopment through the early morning. Gustiness lingers early this evening from ESE and again tomorrow afternoon to near 20kts. Generally light winds expected tonight outside of gusty outflows. && .FIRE WEATHER... Issued at 1212 AM MDT Tue Oct 7 2025 Fire weather will not be a big concern over the next week with a persistent east-southeast flow through the end of the week keeping RH`s in the 20s and 30s. There will be some scattered showers and storms through Wednesday followed by dry weather for Thu/Fri. The breakdown of an upper ridge will bring a surge of moisture from the west going into the weekend and early next week with some widespread wetting rains expected along with higher RH`s and cooler temperatures. Winds over the I-10 corridor may be a concern through Friday with sustained speeds of 15-30mph possible, especially west of Deming. && .PRELIMINARY POINT TEMPS/POPS...
