The episode as NWS ABQ wrote it up.
An unseasonably strong upper level low pressure system churning nearly stationary over New Mexico interacted with abundant low level moisture and instability to provide several days of very active weather. The first day of active weather produced several strong thunderstorms with heavy rainfall over the northern and central high terrain. This activity moved south-southwest into nearby highlands and plains. An impressive downburst wind from a storm near Bingham produced a wind gust near 80 mph. Fortunately, no damage was incurred. The focus then turned to flooding as a slow-moving storm near House produced over 3 inches of rain and nickel size hail. State Road 252 was closed east of House due to high water over the roadway.

NWS Albuquerque, NM wrote its last area forecast discussion before the first event at May 31, 2:40 PM MST, 58 minutes earlier.
Area Forecast Discussion National Weather Service Albuquerque NM 340 PM MDT TUE MAY 31 2016 .SYNOPSIS... Back door cold front has progressed into the northeast quarter of New Mexico as of mid afternoon with a pre-frontal windshift well out ahead of it to near a Roswell to Los Alamos line. Both of these are helping to tweak up low level moisture levels in their wakes with the result being isolated to scattered shower and thunderstorm development. This activity should continue for some time into the evening hours, then perhaps trend down a little. The greatest rainfall and strong storm potential should be near and a little ways east of the central mountain chain. A few showers and storms will also linger into the evening farther to the west...but will produce significantly less rainfall. This pattern change will yield a cooler, wetter weather pattern for Wednesday and to a little lesser degree Thursday for most of the state, the exception being areas mainly west of the Continental Divide. A good warmup is expected late week into the weekend with storms chances diminishing a good bit Friday, but perhaps ramping up east and perhaps && .DISCUSSION... A pretty good crop of showers and thunderstorms has developed along and some distance either side of the central mtn chain. At least two synoptic scale boundaries exist across the fcst area, or at least they did before storm outflows muddied the situation. The more southerly boundary, likely a pre-frontal trough, as of early aftn stretched from roughly Roswell to Los Alamos with the actual back door front across far northeast NM. The main effect will be a weak to moderate upslope flow established across the the east half of the state tonight into Wed and to a lesser degree Thu. Some moderate wind will accompany the front as it slides down the eastern plains and should accelerate at least somewhat through gaps and canyons of the central mountain chain. Currently looking at sub wind advisory speeds into the Rio Grande Valley starting between 5 or 6 pm and 8 or 9 pm and going well into the eve, but there may be a few stronger pockets develop for a few hours perhaps magnified by storm outflow boundaries. Higher dewpoints will follow behind frontal passage and this coupled with upslope flow on the eastern high plains and eastern faces of both the central mountain chain and the continental divide will fuel thunderstorm development Wed and to a lesser extent on Thu. Temperatures will fall 10 to 15 degrees below average in central to eastern NM Wednesday, rebounding slightly into Thursday. Some remnant moisture will be available for recycling on Friday, but fcst models have, for the past couple days now, trended toward less precip coverage so pops were lowered a bit, though not as drastically as model averages. Upslope areas of the higher terrain will be best storm candidates Fri with slight chances continuing over the high terrain Sat. A highly amplified ridge of high pressure aloft will set up over the western U.S. while a wind shift could potentially slide into eastern NM with some moisture advection helping storm chances, espec by Sun. Daytime temps will fall back a few degrees in the east into Sunday due to the aforementioned wind shift. 43 && .FIRE WEATHER... Overall forecast theme remains the same. Today was the main transition day with cooler and more moist conditions on tap for the majority of the area through Thursday. The AZ border country will experience the driest conditions during this period. A budding atmospheric ridge will develop over the intermountain west as the week progresses and influence more and more of our weather late week into the weekend. This means a warming and drying trend from west to east. The main fly in the ointment will be back door cold frontal surges across the eastern plains. The extended period looks to be muddled with less confidence due to the interplay between Pacific lows and the upper ridge. Models are having a hard time dealing with the low which is to be expected. The squeeze play between the cut off Pacific low currently located over southern AZ/northern Mexico and the translating westward/southward back door cold front will continue during the rest of today into tonight. Humidity recoveries will be much higher tonight compared to last night. Drier storms will be found across western areas and the wetter variety will be found across central/eastern areas. Gusty outflow wind will be most prevalent across fire weather zones 105/106 and 109 or southwest portions of the forecast area. Storms will also be slow to move and have erratic motions. High confidence for a moisture gradient to set up between the Rio Grande Valley and AZ state line Wednesday. Based on the time of year...this means extra shower and thunderstorm activity favoring the western highlands and southern portions of the forecast area. A mix of dry and wet activity, meaning small footprints of wetting rain, would be found west of the Rio Grande Valley. Wetter activity elsewhere. The strongest gust potential due to the drier storms would be found near the AZ state line and Four Corners area. Humidity values will be unusually high east of the Continental Divide with below normal temps. Mixing heights will be much lower although remain on the higher side west of the Continental Divide. Much more stable across the east. There is high confidence that the atmosphere will experience a transition Thursday/Friday as the cut off Pacific low slowly moves off to the east and ridging takes over. Transport and storm steering flow will change to a more northerly direction. Storms would tend to favor the central mountain chain as the residual moisture recycles out in the form or showers and thunderstorms. Western areas would also experience some drier showers and thunderstorms but the coverage would lessen. Expecting near to a little above normal temperatures on Friday across the majority of the area. The GFS/ECMWF and Canadian models are picking up on another back door cold frontal surge late Friday or early Saturday. This would jive with the atmospheric ridge pattern over the intermountain west. How far the extra moisture surges westward is always a question mark with these types of flows but anticipate a further west progression due to thunderstorm outflow enhancement. The current RH forecast grids may not reflect that as well. Either way...lower humidity and warmer temperatures would be found near the AZ state line. Thunderstorm coverage would most likely increase due to this feature with wetting moisture favoring the central mountains eastward. Early next week will largely be determined by the next Pacific low and ridge interplay. As suspected...the models are having a hard time dealing with the interplay. Suspect the upper low will end up being more of a player during the earlier half of next week and perhaps intensify storm coverages across the forecast area. Just way to early to say one way or the other so confidence is not as good during this period. 50 && .AVIATION... 18Z TAF CYCLE Lots of aviation hazards today due to the upper and lower level pattern. The western half will be impacted by higher based SH/TS. Pretty hit and miss with slow storm motions and erratic behavior. Gusts between 30 to 45 kt for a short duration possible with this activity through the early to mid eve. More widespread SH/TS will be found along the east slopes of the central mtns eastward during day and night period. This is due to a back door cold front. Use vis restrictions for some of the eastern activity. Eventually the atmosphere will stabilize across the east and lead to low cigs/vis restrictions. Likely terminals to be impacted include LVS and TCC although more LVS in terms of IFR/LIFR possibilities. Central terminal sites such as ABQ/AEG/SAF could also experience some lower decks although intermittent. && .PRELIMINARY POINT TEMPS/POPS...
