Area Forecast Discussion...UPDATED
National Weather Service Albuquerque NM
555 PM MDT Sun Jul 26 2020

.AVIATION...
00Z TAF CYCLE
Scattered-to-numerous showers and thunderstorms will continue to
stream northward and northeastward across the forecast area through
the evening, then coverage should decrease to scattered-to-isolated
after midnight. Stronger cells will be capable of wet microbursts
with erratic wind gusts up to 40 kt. Late tonight and Monday morning,
a moist back door front will trigger additional showers and storms as
it drops southward through the northeast and east central plains.
Scattered-to-numerous showers and thunderstorms will redevelop
Monday afternoon and evening, and these will again be capable of wet
microbursts.

.PREV DISCUSSION...303 PM MDT Sun Jul 26 2020...
.SYNOPSIS...
Daily rounds of showers and thunderstorms will continue through
Tuesday. Slow and erratic storm motions will create locally heavy
downpours and increase flash flooding risk. By midweek, the upper
high migrates into the Desert Southwest from southern California,
bringing drier air and warmer temperatures in its wake. Storm chances
improve by late week, favoring the central mountain chain and
eastward.

&&

.DISCUSSION...
SHORT TERM...(TONIGHT THROUGH MONDAY NIGHT)...
Tonight thru Monday night will feature the most significant and
widespread storm coverage so far this monsoon season. An upper level
speed max is currently moving north-northeast along a sharp gradient
of deep monsoon moisture along the AZ/NM state line. Meanwhile, an
upper level high is strengthening over west TX while drifting west
into eastern NM. These two features will stretch the monsoon plume
over northern and central NM thru Monday as a back door cold front
slides southwest into northeast NM. PW values within the plume are
maxing out btwn 1.2 and 1.5", which is about as good as it gets for
late July. Storm motion will evolve from SW to NE late today into a
slow and erratic mode by Monday with torrential rainfall rates from
any direct hits. This pattern on top of recent heavy rainfall will
elevate the risk for flash flooding just about anywhere across the
area. Near-term models and MOS progs are hinting at widespread storm
coverage Monday developing into a large area of rain Monday night.
The most likely area for persistent overnight rainfall will be over
the northern third of the state as the back door frontal boundary
becomes stationary over the area and the aforementioned speed max
rounds the upper high. Flash Flood Watches are likely to continue
thru this period.

LONG TERM...(TUESDAY THROUGH SUNDAY)...
Rich monsoon moisture continues to enhance shower and thunderstorm
potential Tuesday, before a sharp decrease begins midweek.
The axis of the theta-e ridge drapes itself over New Mexico early
Tuesday morning, as the upper high retrogrades to the west, keeping
low level moisture in place. The GFS shows run- to- run consistency
of above normal PWATs, in agreement with the NAEFS which suggests
that values will continue to be 1.25 standard deviations above
normal. Light NW steering flow on the eastern periphery of the high
will combine with high PWATs, creating storms capable of heavy
downpours across the northeast.

Model consensus is good that the high aloft will migrate back into
the Desert Southwest Wednesday from southern CA, strengthening as it
traverses east. Dry, subsident air will sharply decrease the
potential for precipitation Wednesday into Thursday. PWATs are
anticipated to drop from a near max of 1.2" Tuesday to 0.5"
Wednesday; nearly two standard deviations below normal, according to
the NAEFS. That said, carried over some PoPs in the high terrain,
consistent with the NBM. As heights aloft increase with the high's
advancement, temperatures will begin to climb, pushing some locales 5
to 9 degrees above normal. Relief is thankfully on short order, as
moisture reenters the domain by the weekend, with storm chances
favoring areas along and east of the central mountain chain.

Guyer/12

&&

.FIRE WEATHER...
The monsoon plume will remain centered over NM thru Tuesday with
scattered to numerous showers and storms producing heavy rainfall
and localized flash flooding. Storm motion will be toward the north
and east through tonight then become slow and erratic Monday before
shifting to the southeast Tuesday. A strong area of high pressure
will develop over NM Wednesday thru Friday with hotter temperatures
and less coverage of showers and storms with heavy rain.
