801 FXUS64 KEPZ 201128 AFDEPZ Area Forecast Discussion National Weather Service El Paso TX/Santa Teresa NM 528 AM MDT Wed May 20 2026 ...New AVIATION, FIRE WEATHER... .KEY MESSAGES... Updated at 525 AM MDT Wed May 20 2026 - Dry, southwest winds continue each afternoon through the work week. Near normal temperatures for mid May. - Slight chance for showers and thunderstorms this weekend, focused mostly over the high terrain. && .DISCUSSION... Issued at 1033 PM MDT Tue May 19 2026 ...TUESDAY THROUGH FRIDAY... Longwave troughing over the Intermountain west can be seen via mid- level water vapor satellite imagery. With most of the energy associated with this trough well off to the north and east, very little in terms of sensible weather impacts will be felt locally on Wednesday. The only thing worth mentioning is that winds on Wednesday will remain in the low-end breezy category with winds out of the southwest at 10-20 mph sustained with isolated gusts to 25-30 mph during the afternoon. Mentioned in previous forecast packages, the weak moisture boundary at the surface will ebb and flow over eastern portions of the forecast area on Wednesday, generally east of the HWY54 corridor. Models guidance shows DP temps in the 40-50 degrees range across far eastern El Paso County, Hudspeth County, and Sacramento Mtn east slopes. But by the afternoon, the dry westerlies will kick into gear and push said low-level moisture back to the east. There are mentionable PoPs (15%) in the grids across far eastern Otero and Hudspeth Counties where an Isolated shower/storm will be possible. Temperatures on Wednesday will remain right around the seasonal average. On Thursday, the dry westerlies win out again as the moisture boundary tries to make another westward push during the morning hours. Expected low-end breezy winds and near seasonal afternoon temperatures. For Friday, an extension, or weak piece of energy will cutoff from the main flow aloft over southern AZ and northern Sonora. As it does so, short wave ridging will build in quickly over the forecast area. Again, expected fair weather conditions with light winds and afternoon temperatures near seasonal for the later part of May. ...MEMORIAL DAY WEEKEND... The overall flow aloft this weekend will become weak as the aforementioned cutoff low quickly translates east and upper level ridging develops in it`s wake. This will ultimately result in fair weather conditions on Saturday and Sunday with light winds and near seasonal temperatures. For Monday, Memorial Day, the slightest bit of moisture will work it`s way into the area with meager but sufficient moisture profiles. As of now, NBM guidance and it`s respected global models paint slight chances of rain across portions of the area Monday afternoon and evening. Being 5-6 days out, confidence remains LOW, but something to keep an eye on. && .AVIATION... (12Z TAFS) Issued at 525 AM MDT Wed May 20 2026 VFR conditions are expected with SCT-BKN250. Light and variable winds this morning will become SW`LY (190-230) with speeds of 10 to 15 knots and gusts up to 25 knots. Winds will subside after dark. && .FIRE WEATHER... Issued at 525 AM MDT Wed May 20 2026 Elevated fire weather conditions are expected today as 20-foot winds around 15 MPH will combine with min RH values near 10%. Far eastern areas could see a shower or thunderstorm, but chances are low. Any storms that do form would have a dry lightning and gusty wind risk. Winds will gradually decrease each day toward the weekend with continued dry afternoons. Venting will be excellent. As we approach the weekend and go into next week, increasing moisture will lead to at least low shower and thunderstorm chances. Afternoon highs will be within a couple degrees of normal for this time of year. && .PRELIMINARY POINT TEMPS/POPS...
