The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS El Paso, TX wrote its last area forecast discussion before the first event at Jun 26, 2:22 PM MST, 2 hours 4 minutes earlier.
Area Forecast Discussion National Weather Service El Paso Tx/Santa Teresa NM 322 PM MDT Mon Jun 26 2017 .SYNOPSIS... A gradual drying of the area continues over the next several days. Low level moisture will persist tonight for scattered thunderstorms, but drying will begin on Tuesday and Wednesday, with just isolated thunderstorms possible. By Thursday and Friday the drying trend peaks with little or no chance of rain in any area. Temperatures will warm back above normal by Wednesday, and most lowland areas will be back in the triple digit heat. By Saturday and Sunday, some moisture moves back in for a slight chance of thunderstorms both days. && .DISCUSSION... Upper high persists over the northern Baja, while upper low continues to churn over British Columbia. At the surface plenty of moisture persists so expect scattered thunderstorms again tonight. Models continue to show plenty of MUCAPE and low LIs for convection. Good directional shear should be able to allow long duration of some updrafts, so mod/large hail is possible. PWs of around 1.1 - 1.2 inches also suggest some heavy rain/local flooding. For Tuesday through Friday...Baja high begins shifting further west and a bit further south while British Columbia low drifts east with corresponding trough dropping south of the low over the central Rockies. This will bring main polar flow down to New Mexico and usher in drier period. Dewpoints Tuesday will be mostly in the 50s to start the day, but low level west flow will develop out west and begin moving drier air in. Chance of rain may be limited to areas east of the Rio Grande Valley as dewpoints fall into the 30s out west by afternoon. Drying continues on Wednesday, with dewpoints in the 30s all areas, with even 20s up north. No POPs in for Wed-Fri period-been awhile since we could say that. With the drying, temperatures will warm up. Looks like another stretch of triple digit temps for the lowlands, though not as warm as the last stretch that ended a few days ago. Saturday and Sunday...Models showing a bit of moisture increase as upper flow weakens with ridge of high pressure building back east over northern Mexico. This will allow some limited moisture at mid levels (600mb) to spread north over the area under the weak upper flow. GFS shows PWs back to one inch over southern zones, slightly less to the north, with moderate MUCAPE values. Don't have much confidence yet in this moisture return but will put in low POPs for both days. && .AVIATION...Valid 27/00Z-28/00Z... P6SM SCT070-090 SCT-BKN150-200 through much of the period. Expect cluster of VRB25G40KT 1-3SM TSRA BKN020-040 to be ongoing over northern and eastern areas but gradually decreasing in intensity and coverage through 06Z. Isolated to widely scattered storms then expected until after 18Z mainly east of Rio Grande and Gila region. && .FIRE WEATHER... Thunderstorm coverage will be a little less today than over the weekend with a continued decrease on Tuesday. Best chances will be over mountains and areas east of Rio Grande. Winds will start to shift around to the west to southwest tomorrow which will begin the drying out which will take full effect for the later half of the week when relative humidities will be back to around 10 percent. Winds will be on the increase Wednesday and Thursday which could come close to 20 mph. With recent rains, fuels may need a little more time to dry out to warrant any warnings. Some thunderstorm chances will return for the weekend. && .PRELIMINARY POINT TEMPS/POPS...
