Area Forecast Discussion
National Weather Service Albuquerque NM
330 PM MDT Mon Jul 26 2021

.SYNOPSIS...
Above normal moisture and a favorable upper level weather pattern
will favor scattered thunderstorms across much of New Mexico this
week. There may be a brief decrease in activity mid week, but an
upper level low moving across Mexico this week may bring an increase
of thunderstorm activity Friday and Saturday. With wet grounds in
areas of New Mexico that have already seen rainfall, any additional
rainfall will quickly run off causing flash flood impacts and debris
flows on burn scars. With no any one day or any one location expected
to have higher chances of storms than another, please continue to
monitor forecasts and have several ways to get warnings for flash
flooding.

.DISCUSSION...
SHORT TERM...(Tonight through Tuesday Night)...

Expansive 500MB high pressure area was north and east of NM today.
Still, plenty of moisture around with widespread showers and
thunderstorms this afternoon. Storm motions have been slow and
erratic due to the two high pressure centers. This activity will
continue into the night once again, but should be mostly over a
little after midnight.

The northern high pressure area will become dominate Tuesday with
the broad center over CO/NE. Storm motion will be mostly east to
west, which keeps storms away from the eastern plains, but it will be
active once again, maybe a less than today. Scattered showers and
thunderstorms will develop from the east slopes of the central
mountains to the AZ border. Convection will continue into Tuesday
night.

LONG TERM...(Wednesday through Monday)...
Overall daily thunderstorm activity should continue this week with
above normal moisture expected to remain over much of New Mexico and
a favorable upper level pattern. The morning 12Z sounding here at
KABQ had a PWAT of near 1.2 inches. GFS ensembles show PWAT around
1-1.2 inches to persist this week in the ABQ area so there should be
plenty of moisture for storms. Upper level analysis has a upper level
ridge centered over N and C Rockies and then expanding into the
Plains. This ridge becomes stronger this week as it moves into the C
Plains. By the end of the week GFS/ECMWF ensembles show this ridge
sliding more into OK/TX. While this happens an upper leve low now
over the western Gulf moves NW across northern Mexico towards AZ/NM
border by Friday. This allows for SE flow aloft to increase and for
moisture from the Gulf to move into New Mexico. While thunderstorm
activity may take a break on Wednesday with maybe isolated to
scattered activity, there could be an increase in coverage Thursday
into Friday as this pattern develops. Flow may be more from the SE on
Saturday but we may also see the ridge build towards west Texas.

GFS and ECMWF ensembles have some slight differences with the
evolution of this ridge for the weekend. ECMWF wants to bring the
ridge into NM early next week while the GFS maintains a weaker ridge
and more thunderstorm activity. Both models bring in a backdoor front
into NE NM Sunday into Monday which would increase thunderstorm
activity across the state. In the 8-14 day time frame, this upper
level ridge may finally take hold over NM and the southern Rockies to
provide drier but warmer conditions, but this will hinge on how
strong of a ridge develops. There still should be enough moisture
left for isolated thunderstorm activty but not enough to warrant even
near normal precipitation.

What does this mean for New Mexico? We still remind everyone to
remain diligent to check the forecast daily, have multiple ways to
get warnings and stay away from arroyos/swift moving water. The flash
flood potential remains this week but maybe not quite to the degree
we have expreienced this past weekend. The threat will be more
isolated and localized, but that doesn't mean it won't cause an
impact. The potential for burn scar flash flood debris flows will
still be there and affect outdoor activities in and around those
areas. Have ways to get warnings and have a plan to stay out of flash
flood situations.

.FIRE WEATHER...
There are no critical fire weather concerns over the next week with
daily rounds of thunderstorms producing widespread wetting rains and
some soaking rains with possible flash flooding, especially over
recent burn scars. There will be a subtle decrease in storms Tuesday
and Wednesday, but they will likely increase again for the end of the
week as an inverted trough/easterly wave passes to our south and
west. It will be able to draw moisture north into NM. In addition,
the upper high will move east, allowing the typical monsoon moisture
pattern to impact the Land of Enchantment this coming weekend and
beyond.

&&

.AVIATION...
18Z TAF CYCLE
Another active monsoon day with storm coverage again favoring areas
along and west of the central mountain chain with isolated activity
across the east. Steering flow will generally move storms in a north
to northeast direction, but slow and erratic motions are possible.
Heavy rain, frequent lightning, and strong downburst winds will be
possible with the stronger thunderstorms. Impacts are possible at all
TAF sites, but highest confidence is in TAF sites across central and
western NM, including KLVS. Storm coverage will diminish through
tonight. Mostly VFR conditions except brief MVFR in thunderstorms.
Occasional mountain obscurations as well.
