Area Forecast Discussion
National Weather Service Albuquerque NM
316 PM MDT Sat Jul 31 2021

.SYNOPSIS...
A backdoor cold front has dropped into northeastern New Mexico,
triggering storms that are capable of heavy rainfall, mainly along
and east of the central mountain chain. The front will continue to
push low-level moisture south and west into the state this evening.
Storm coverage will increase on Sunday and daily rounds of storms
will continue through at least early next week, with locally heavy
rainfall and flash flooding possible. By mid-week, storm coverage
will trend downward slightly. High temperatures will be below normal
across much of northern and central New Mexico Sunday and Monday,
with highs closer to normal by the end of the work week.

&&

.DISCUSSION...
SHORT TERM...(TONIGHT THROUGH SUNDAY NIGHT)...
Temperatures will continue to cool Sunday and showers and
thunderstorms will continue to increase in coverage and wetness as
moisture continues to advect into the forecast area from the east
and disturbances track south and southeastward over the state. A
backdoor front will push through gaps in the central mountain chain
this evening with east canyon wind gusts up to 35 mph from Taos
southward through Santa Fe and Albuquerque. This front will progress
westward into AZ by Sunday morning, setting the stage for numerous
thunderstorms with the potential for locally heavy rainfall areawide
on Sunday afternoon and evening. With high pressure aloft
reorganizing over SE AZ, storms will move slowly off NM's high
terrain at speeds up to 10 mph toward the south and southeast on
Sunday. WPC is highlighting the central mountain chain and much of
the eastern plains with a slight risk of excessive rainfall on
Sunday and Sunday night. Will let the night shift take into
consideration the antecedent moisture that falls this afternoon and
evening before we issue another Flash Flood Watch for Sunday.

LONG TERM...(MONDAY THROUGH SATURDAY)...
The upper-level high will remain in place to the west on Monday,
with a stream of monsoon moisture focused mainly west of the central
mountain chain. Although PWAT’s will be slightly less than Sunday
(near 1.2” or lower), storm motions will generally be slow and to
the south. This may lead to another round of locally heavy rainfall
and flash flooding. Tuesday will be much of the same, with a weak
disturbance riding over the high.

By Wednesday, the high starts to slowly migrate eastward, leading to
a downtick in storm coverage across western and central areas of the
state. Models are in decent agreement that the high tries to build
over New Mexico, with an overall warmer and drier pattern to end the
week. But, isolated to scattered storms will still be possible each
afternoon. While high temperatures 5-10 degrees below normal start
off the week, highs will gradually warm by late week to near normal.

44/31

&&

.FIRE WEATHER...
The wet monsoon pattern will continue through Thursday along and
east of the continental divide as the high pressure system aloft
builds west of NM and repeated disturbances pass south and
southeastward over the forecast area. High temperatures will remain
near and below normal through Thursday with all the moisture and
precipitation in place. Toward the end of the work week, an
inefficient process of moisture recycling will result in less
precipitation coverage and intensity over northern and central NM as
a ridge axis aloft stretches from southern CA northeastward across
northern NM. This will allow temperatures to trend warmer.

44

&&

.AVIATION...
18Z TAF CYCLE
Scattered to numerous showers and thunderstorms are expected this
afternoon and evening, then scattered to isolated activity is
forecast to linger after midnight along and east of the central
mountain chain. A loosely organized high pressure system aloft will
result in slow and erratic storm motions. Meanwhile, a moist backdoor
front will continue advancing southwestward across eastern and
central areas triggering thunderstorms with wet microbursts and
locally heavy rainfall. The front will push through gaps in the
central mountain chain this afternoon and evening with a moderately
gusty east wind below canyons opening into the central valley from
Taos southward through Santa Fe and Albuquerque.
