FXUS64 KEPZ 200435 AFDEPZ Area Forecast Discussion National Weather Service El Paso TX/Santa Teresa NM 1035 PM MDT Tue May 19 2026 ...New DISCUSSION, AVIATION... .KEY MESSAGES... Updated at 1033 PM MDT Tue May 19 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... (06Z TAFS) Issued at 1033 PM MDT Tue May 19 2026 VFR conditions expected through the period with skies SCT-BKN at 25 kft. Winds light at 3-8 knots and VRB through the morning hours. By 18Z, winds will become south/southwest at 10-15 knots sustained with gusts to 20-25 knots. && .FIRE WEATHER... Issued at 1100 AM MDT Tue May 19 2026 Near Critical fire weather conditions for Southwest New Mexico again on Wednesday with continued southwest winds 10 to 20 mph and Min RH 8 to 12%. Winds are forecast to remain below Red Flag criteria. Skies will be partly cloudy area wide with passing high clouds. Typical mid May temperatures. Similar weather on Thursday, though we may see some afternoon low level cumulus growth over the high terrain. Minimal changes to temperatures later in the week, along with light southwest flow remaining in place across southern New Mexico.Slight chance of showers and thunderstorms over the weekend, primarily over Lincoln National Forest. This could lead to erratic afternoon wind gusts Saturday/Sunday there. Current fuel status shows ERCs rising past the 90th percentile this week, due in part to sustained dry, breezy weather. Forest conditions are increasingly susceptible to fire starts. There is some concern in new lightning starts over the weekend. && .PRELIMINARY POINT TEMPS/POPS...
