Flash Flooding in New Mexico, August 3, 2022

August 3, 2022 · NWS ABQ · 5 events in 4 counties and zones

While the high pressure centered itself over New Mexico, it was still a very active day on August 3, 2022, thanks to a backdoor front that moved through eastern New Mexico earlier in the day. This front helped to replinish moisture in the area while upslope flow helped to initiate a greater number of thunderstorms compared to the previous day.

What happened

The episode as NWS ABQ wrote it up.

While the high pressure centered itself over New Mexico, it was still a very active day on August 3, 2022, thanks to a backdoor front that moved through eastern New Mexico earlier in the day. This front helped to replinish moisture in the area while upslope flow helped to initiate a greater number of thunderstorms compared to the previous day. Thunderstorms developed by late morning across the typical high terrain areas before becoming more widespread across much of northern and central New Mexico as the day progressed. Heavy rain was common with these thunderstorms, and this resulted in flash flooding, especially on the Calf Canyon burn scar.

.AVIATION...
18Z TAF CYCLE
A backdoor front will continue moving south through the east this
afternoon, providing a northerly wind shift. Also, replenishing
moisture to increase storm chances along and east of the central
mountain chain this afternoon and evening. Storm initiation will
continue on the high terrain with the most numerous coverage across
the Sangre de Cristos and southwest mountains. Storms will move onto
lower elevation areas as the afternoon progresses. All TAF sites
will have the opportunity to see thunderstorm or shower impacts which
include heavy rain, frequent lightning, and gusty and erratic winds.
Showers and storms will be slow to taper off and will likely
continue across the plains past 06Z. The front then pushes through
the gaps of the central mountain chain by 00Z this evening, likely
resulting in a moderate east canyon wind at KABQ. Currently, winds
are expected to remain below Airport Weather Warning criteria.

.PREV DISCUSSION...148 AM MDT Wed Aug 3 2022...
.SYNOPSIS...
A weak backdoor front will replenish moisture across the area later
today through Thursday leading to an uptick in coverage of storms
with an elevated threat for locally heavy rainfall and flash
flooding, especially on and near area burn scars. Storms will favor
central and western New Mexico through the weekend, but may become
more widespread early next week. Temperatures will be above normal
today, but will gradually trend down through the next six days and
be a degree or two below normal by early next week.

&&

.DISCUSSION...
SHORT TERM...(TODAY THROUGH THURSDAY)...
The drier air that was working its way around the H5 high this time
yesterday morning is much more evident on water vapor imagery this
morning. The center of the high is still centered over western NM
with drier mid-level air in place across southern NM. While this
helped to suppress convection yesterday, today will be a different
story. This is thanks to a backdoor boundary or outflow from late
evening storms over CO/KS/NE. This front is working its way through
eastern CO at the time of this writing, and it is expected to begin
nosing into NE NM between 09Z and 12Z this morning. It will then
move quickly through the remainder of the plains through the rest of
the morning, likely reaching the east slopes around 18Z. Replenished
moisture behind this front and favorable upslope flow will increase
storm chances today for areas along and east of the central mountain
chain. Convection will be more isolated west of the RGV with the
exception of the Gila where PWATs will remain around 1.20 to 1.30
inches. So this sets up two primary hot spots for convection today -
the Sangre de Cristos and adjacent highlands as well as the
southwest mountains. The Sacramento and Jemez Mountains will likely
see increased storm activity today as well, but probably not to the
extent as the two aforementioned hot spots. Then of course, outflow
boundaries will help convection fill in across lower elevations as
the afternoon and evening hours progress. Did issue a Flood Watch
today for the major burn scar areas as that threat does increase
compared to yesterday.

The backdoor boundary pushes through the gaps of the central
mountain chain by late afternoon, likely generating a moderate east
wind in Tijeras Canyon and the east side of ABQ. Models indicate
that convection will be slow to completely diminish Wednesday night,
especially across the east where outflow boundaries will likely play
a big part in helping to keep storms going.

The H5 high stays over NM Thursday with its center beginning to
shift eastward over north central/northeast NM. The moisture from
the backdoor boundary is still in play Thursday, and PWATs look to
be well above an inch areawide except across the northwest where
they will be closer to 0.75 to 0.85 inches. Thursday looks to be the
most active day of the forecast period with widespread thunderstorms
and abundant moisture and very slow and erratic storm motions
increasing the flash flooding threat. It's likely that today's Flood
Watch will need to be reissued for Thursday and expanded in coverage
as well.

LONG TERM...(THURSDAY THROUGH TUESDAY)...
The threat for locally heavy rainfall, especially on area burn scars,
will persist into Thursday evening with slow and erratic storm motion
and well above normal PWATs in place. By Friday, the upper high
center will be east over the OK Panhandle, but it will extend a ridge
axis west over the area and begin to focus daily rounds of
convection across central and western NM going through the weekend.
The upper high center is then forecast to build-up a new center to
our west or northwest, with some disagreement on the placement among
the 00Z medium range model solutions. Either way, we'll remain on the
periphery of the circulation with plenty of moisture in place for
active rounds of storms early next week. Temperatures will gradually
trend down from Thursday through Tuesday and be a degree or two below
normal early next week, mainly due to added cloud cover and rain-
cooling.

.FIRE WEATHER...
A very active monsoon pattern is still on tap for the foreseeable
future. A backdoor boundary entering eastern NM this morning will
help to replenish moisture and in turn, increase storm chances for
areas along and east of the central mountain chain. Storm chances
continue to increase areawide Thursday with above normal moisture
values in place. Storm motions will become slower today and more
erratic, increasing the flash flooding threat each day. The high
then establishes itself to our east Friday and this weekend, setting
up the monsoonal moisture plume across western NM and thus focusing
storm chances along and west of the central mountain chain. By early
next week, the high then moves back towards the west, and subsequent
backdoor boundaries will then help to increase storm chances again
for the east.
