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 Nov 30, 10:43 PM MST, 1 hour 17 minutes earlier.
Area Forecast Discussion National Weather Service El Paso TX/Santa Teresa NM 1043 PM MST Mon Nov 30 2020 .AVIATION...06Z TAF CYCLE Dry northwest flow aloft will result in VFR conditions through the period. Winds will be light and variable early in the period, becoming W to NW 5-10 KTS after 17Z. Then a cold front will increase winds after 03Z, becoming N to NE at 15-25 KTS mainly along and east of the Rio Grande. Skies will be FEW- SCT250. && Fausett .PREV DISCUSSION...138 PM MST Mon Nov 30 2020... .SYNOPSIS... Mild, relatively speaking, weather lovers should enjoy Tuesday, which will be near 60 degrees, because a cold airmass plunges into the Borderland come mid to late week. Temperatures Thursday and Friday will likely not reach 50 degrees across the region. Light snow possible western areas Friday, then highly uncertain precipitation chances this weekend, ranging from nothing to modest amounts. Stay tuned. && .DISCUSSION... .SHORT TERM... A slightly cooler airmass is in place today thanks to the cold front that pushed through the Borderland yesterday afternoon/evening. It brought with it some breezy to gusty west slope winds overnight. The tight surface pressure gradient overnight has relaxed enough already today to see only an occasional breeze across the Borderland this afternoon. The exception is Hidalgo and Southern Grant county where it's still windy; gusts to 30-35 have been common along the Lordsburg Playa. Wind will continue to gradually decrease this afternoon, becoming calm tonight. The overall wind direction will be terrain driven. A shortwave in the NW upper level flow will bring in some high clouds tonight, which may deter some radiational cooling. Regardless, lows will drop below freezing area-wide. Tomorrow, an amplified ridge sets up over NW Canada, with a trough dropping south into northern New Mexico by the end of this short- term forecast period. Despite height falls through the day, the westerly surface wind and ridge amplification should allow high temperatures to increase to right at, or just below, seasonal average (highs in the lower 50s/upper 60s in the lowlands). Enjoy it while you can... much cooler weather is on the way. && .LONG TERM... Interesting long term pattern shaping up. Strong positive PNA pattern continues early December. At the same time, neutral to trending negative AO/NAO pattern(s) develop(s). As a result? Substantial blocking and high amplitude pattern will activate across North America, with anomalously high heights across much of northern to northwestern Canada, and south or in the vicinity of Greenland. Upper low will be trapped under this pattern, pushing south into the Borderland, or to the southwest, come late week into the weekend, where a threat for modest precipitation lies. Firstly though, we'll have to deal with a cold, arctic airmass, plunging into the Desert. High temperatures will likely fall short of 50 degrees come Thursday and Friday, with cold overnight low temperatures. Winds Wednesday night into Thursday will be brisk at times, likely leading to some chilly windchills as well. Where things get a little messy is Friday and beyond into the weekend. ECMWF continues to suggest, along with EPS, a very strong deepening upper low sitting just to the west/southwest of EPZ CWA. Strong moisture advection and hence mod to hvy precip overspreads the area, especially western regions, which will be closer to upper low. GFS, GEFS, CMC, and GEPS suggest a less amplified upper low overall with much less precip, and perhaps none at all. So this will certainly be watched, but leaning towards rain/snow showers Friday through the weekend, but timing, strength, and evolution of upper low will be everything. For instance, GFS has the aforementioned upper low phasing and moving east with another piece of energy, which is a catalyst for a tremendous slug of moisture NEXT Tuesday... Thinking at least a light precip possibility will be in the cards, timing is uncertain, however. Whether or not this precip threat does establish temperatures through this period (next weekend into early next week) will be somewhere near to slightly below normal for this time of year. && .FIRE WEATHER... The weather pattern over the next several days will promote dry conditions and cooler overall temperatures. Aside from Tuesday, which will warm to near normal (min RH 12-18 percent; light wind), the cooler temperatures will cause Min RH to stay above 20 percent. A strong cold front will slide through with breezy winds Tuesday evening, promoting cooler temperatures through the end of the week. Temperatures on Thursday and Friday will be 10-20 degrees below normal. Vent rates will generally be poor to fair, with the exception of fair to good in spots on Thursday. && .PRELIMINARY POINT TEMPS/POPS...

Hidalgo County will continue to see wind gusts to 25 to 35 mph until about mid day before gradually decreasing through sunset. Some patchy blowing dust will be possible with these stronger wind gusts. They will also be capable of blowing around loose unsecured objects. High temperatures will be 8 to 10 degrees cooler today. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday Low temperatures will drop below freezing for most locations each night. It is important to remember to protect your pets, plants, and pipes every night from these frigid temperatures. A backdoor cold front will push through Tuesday night briefly creating spotty breezy winds, followed by an upper level storm system swinging through the area late in the week. As of now, this system looks to usher much colder air into the Borderland. There still appears to be no real chance for precipitation through the week. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. Pegram
