The episode as NWS ABQ wrote it up.
A small cluster of thunderstorms that developed over the higher terrain of western Mora County moved southeast toward Wagon Mound shortly after sunset. Severe outflow winds from this storm cluster downed a large tree branch and associated power line onto the side of a home three miles north of Wagon Mound. Fortunately, no damage occurred to the property. Torrential rainfall that accompanied the storm added a significant amount of water to a nearby lake. Residents reported being able to see the lake from their property for the first time in many years. Other parts of San Miguel and Mora counties reported daily rainfall totals between one and three inches.
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 Albuquerque, NM wrote its last area forecast discussion before the first event at Aug 7, 4:49 PM MST, 2 hours 41 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Albuquerque NM 549 PM MDT Mon Aug 7 2017 .AVIATION... 00Z TAF CYCLE Band/line of convection across eastern NM will continue to redevelop into the late night hours. Rain cooled air over eastern NM will push westward through the canyons of the central mountain chain around 08/02Z with gusty east and southeast winds at KABQ and KSAF respectively. Areas of upslope MVFR/IFR cigs will develop several hours after sunset from the east slopes of the central mountain chain east to the TX line. Gusty east and southwest winds will diminish toward sunrise Tuesday with low clouds gradually dissipating across the east during the late morning hours. 33 && .PREV DISCUSSION...310 PM MDT Mon Aug 7 2017... .SYNOPSIS... Strong to severe storms capable of producing locally heavy rainfall and localized flash flooding will move across the Eastern Plains overnight and impact locales such as Tucumcari, Clovis, Portales and Roswell. Another round of storms is forecast Tuesday afternoon and overnight, favoring the South Central Mountains and Northeast Plains. Wednesday is looking like even more of a down day in terms of storm coverage, with daytime temperatures at or above normal as high pressure strengthens over the state. Look for an uptick in storm coverage and intensity toward the end of the work week and into the weekend as another backdoor front helps to replenish moisture. Daytime temperatures will trend below normal over the weekend thanks to additional cloud cover and rain cooling. && .DISCUSSION... 24hr surface dewpoint changes values are up an average +3 degrees across the east compared to yesterday at this time, which is resulting in increased surface based instability. At the same time, a backdoor cold front is making southwest progress across the Eastern Plains and forcing convection along/near the boundary. Storms that developed along the east slopes of the Central Mountain Chain and adjacent Eastern Highlands are moving southeast and will interact with this boundary and an increasingly buoyant atmosphere to produce strong to severe storms with locally heavy rainfall and the potential for localized flash flooding this evening and overnight. Storm organization is possible across the Southeast Plains later this evening as convection moving into the Pecos River Valley link-up with the backdoor front. Maintained a locally heavy rainfall mention in the forecast tonight across portions of the Eastern Plains, with amounts between 2-3 inches possible. Dry air aloft will continue to rotate around the upper high circulation into western New Mexico Tuesday, limiting storm coverage and intensity across the western half. More storms are forecast Tuesday afternoon/evening across the eastern half, with the South Central Mountains and Northeast Plains favored. Any severe storms that develop late Tuesday will likely be over the Northeast Plains where favorable instability and atmospheric shear will reside. Both the latest GFS and NAM show convection persisting overnight Tuesday into early Wednesday morning across the northeast, sustained by healthy low level inflow of Gulf moisture. Wednesday is still looking like a relative down day in terms of storm coverage/intensity, as the upper high pumps-up over the state and dry air overtakes much of central and northern New Mexico. Another backdoor front will push into the Northeast Plains Wednesday night, but there is some disagreement among the 12z model solutions in terms of how far southwest it progresses which leads to some forecast uncertainty in terms of storm coverage/placement on Thursday. The upper high will relocate to over west Texas by Friday, allowing moisture to flow around the circulation back into western New Mexico. Look for a convective uptrend going into the weekend, especially after another backdoor front gets in the mix Saturday night into Sunday. Daytime temperatures will trend below normal over the weekend thanks to added cloud cover and rain-cooling. 11 && .FIRE WEATHER... Ridge of high pressure is centered south of NM. It will continue to slowly build and move north through Wednesday. Yesterday's back door front has delivered plenty of low level moisture across the east today, and widespread showers and thunderstorms continue to increase in coverage and intensity this afternoon over and east of the central mountain chain. They will continue through this evening as they move southeast, perhaps congealing into an MCS overnight across the east central plains and Chaves County. A few of the storms through this evening could be severe. The outflow boundaries from the thunderstorms along the east side of the central mountains will eventually spill into the Rio Grande Valley this evening with gusts up to 40 mph. Thunderstorm coverage should be less Tuesday through Wednesday as the high pressure aloft strengthens a bit and moves over top of NM. Temperatures will warm and humidities will lower significantly. The bulk of the convection will again be in the eastern half of the state. Another gusty and moist back door cold front will push southward into the eastern plains Wednesday night, but may wobble back and forth Thursday through Saturday, before another, stronger back door front drives south and west Saturday night. While all of this is going on the high pressure center over NM will drift southeast, allowing a direct surge of monsoon moisture to finally enter western and northern NM starting Thursday and lasting into the weekend. A significant short wave trough dropping southeast into NM over the weekend will force the high back toward NM. But the moisture will not be going anywhere and widespread convection is expected Thursday into early next week. Spotty high Haines values will be noted Wednesday in the northwest, otherwise only moderate or lower values through the forecast period. No widespread poor vent rates are forecast, but areas of poor rates are forecast in the southwest and northeast Thursday, with somewhat more coverage Friday through the weekend. CHJ 40 && .ABQ WATCHES/WARNINGS/ADVISORIES... None. && 11
