Area Forecast Discussion...CORRECTED
National Weather Service Albuquerque NM
304 PM MDT Mon Aug 23 2021

.SYNOPSIS...
Fewer storms and above average daytime temperatures will be the trend
for Tuesday through Wednesday. Highs in the mid 90s to near 100 are
expected across eastern New Mexico while upper 80s and 90s will
be common for the central and west. These readings will be 5 to 10
degrees above seasonal averages for most locales. Storm coverage
will then ramp up on Thursday, especially for the northern half of
the state, as a disturbance passing north of the state draws
moisture northward. A relatively active monsoon pattern will
persist Friday into the weekend with daily rounds of thunderstorms
favoring the west and north. Daytime highs should trend closer to
seasonal average for Thursday through the upcoming weekend.

.DISCUSSION...
SHORT TERM...(TONIGHT THROUGH TUESDAY NIGHT)...
594dam 500mb high centered near the ArkLaTex and extending a ridge
axis west into southern NM per the 12Z upper air analysis. The latest
water vapor imagery shows moisture from the eastern Pacific, where
TS Marty resides, being pulled northeast across northern Mexico and
into southern NM. The 12Z KEPZ sounding confirmed this with a well
above normal PWAT of 1.5" and even the KABQ sounding had a PWAT near
1". Surface dewpoint temperatures were an average 4 degrees higher
across portions of central and western NM at 1PM compared to 24hrs
prior. Given some daytime heating, all of this adds up to a decent
round of storms this afternoon, with the focus for deeper convection
and stronger storms capable of producing locally heavy rainfall
generally south of I-40 in the higher PWAT airmass. Storms closer to
our southern border under the ridge axis will be moving slower and
more capable of producing torrential downpours with localized flash
flooding. Both the latest HRRR and HREF show convecting winding-down
shortly after sunset, but the NAM shows precipitation continuing
overnight across southern portions of our area similar to last night.
Regardless, coverage and intensity will trend down with the loss of
daytime heating this evening.

Tuesday is looking very similar to today overall with slightly
higher pressure heights near 593dam at 500mb and above normal high
temperatures, especially across eastern NM. A drier airmass to our
west is forecast to get wrapped into the upper high circulation
across northwest and north central NM Tuesday and should put the
brakes on convection north of I-40 and west of I-25. Storms across
the southern high terrain will be capable of producing locally heavy
downpours Tuesday afternoon, with the potential for localized flash
flooding once again.

LONG TERM...(WEDNESDAY THROUGH MONDAY NIGHT)...
Wednesday looking to be among the least active days of the
forecast period. Shortwave trough modeled to move inland long the
northern CA and PacNW coasts early Wednesday resulting in weak
compensatory height rises downstream over our part of the world.
As a result, the models generally show the strong 595 dam H5 high
over the Southern Plains briefly expanding westward. Latest
blended PoP guidance trended a little downward for Wed PM and this
seems reasonable under what should be slight warming aloft and A
weakly forced environment.

The above mentioned upper trough to cross the Great Basin eventually
nearing the central Rockies late Thursday. Ahead of this wave, a
corridor of enhanced forcing for large-scale lift should develop and
support a noticeable uptick in storm coverage particularly from WC
through NW and NC areas for Thursday afternoon and evening. We would
not rule out the possibility of strong if not severe storms in this
regime given increasing swly flow aloft though storm motions may
preclude significant FF potential. PWAT time series reflect values
generally at or just above seasonal averages. And with the west to
east oriented upper ridge axis getting forced southward, we are not
likely to see a significant moisture tap during this period. The
tail-end of this upper wave should graze northern New Mexico
Thursday night. Thereafter, GEFS and EPS mean 500mb height fields
suggests the upper high reorganizing over the area this weekend with
the ridge axis near the NM/AZ line. Meanwhile, this forecaster was
expecting to see a weakening backdoor cold front appear across
northeast NM in wake of the upper trough passage through the Central
Rockies. There may be some evidence for late Friday with another
frontal feature for Sunday, but nothing too impressive. KJ

.FIRE WEATHER...
No fire weather concerns for at least the next seven days as
northern and central NM remain under the influence of ridging aloft
with bouts of wetting storms. Some drying through Thursday will
limit the wetting rain footprint, which should expand Friday through
the weekend as the ridge weakens and PWATS creek back to normal or
slightly above normal for the end of August. 11

&&

.AVIATION...
18Z TAF CYCLE
VFR conditions prevail and are forecast to persist through the TAF
period, except for possible brief MVFR conditions in/near isolated to
scattered convection this afternoon/evening. Strong/erratic wind
gusts will accompany showers and storms today. 11
