Area Forecast Discussion
National Weather Service Albuquerque NM
1221 PM MDT MON AUG 8 2016

.AVIATION...
18Z TAF CYCLE
Storms firing up a little earlier compared to the past several
days. Storms will be hit and miss but impacts are expected such as
at most of the terminal sites with the exception of FMN. Really
hitting gusty outflow/downdraft wind in the tempo -shra groups.
Used VCTS at SAF/LVS/ROW/GUP but could see an upgrade to VCTS at
AEG/ABQ if the storms can hold together from the west. Storm
activity overnight is expected to be less compared to last night.
Gusts between 30-40 kt and potentially higher will be associated
with some of the storms.

.PREV DISCUSSION...336 AM MDT MON AUG 8 2016...
.SYNOPSIS...
After staying to the east of New Mexico for some time, high
pressure aloft will be moving back over the state today and into
Tuesday. This will start to suppress storm development some,
especially in the west central to northwestern sections of the
state where drier air will visit. Still, scattered to numerous
storms are expected to develop today and Tuesday afternoon, namely
from the southwestern mountains northeastward to the Sangre de
Cristos and high plains of far northeastern New Mexico. Into
Wednesday high pressure will drift back eastward into Texas and a
Pacific trough will move inland over the Intermountain West. This
will steer a deep plume of subtropical moisture into Arizona and
western New Mexico, increasing the chances for showers and
thunderstorms there.

&&

.DISCUSSION...
High pressure aloft will sidestep westward back into NM today
while an anomalously deep upper low spirals over WA state. This
will start to disrupt the moisture plume over NM. Overall
precipitable water values have declined a tenth or two in much of
the state over the past 24 hours, and a slug of drier air aloft is
visible on water vapor and the CIRA PWAT imagery, working into far
western portions of NM. With the position of the high over
southern NM later today, this will steer more of that drier air
into the west central and northwestern zones of NM, limiting storm
development. A healthy crop of storms is still expected to blossom
along an axis stretching from the southwestern mountains to the
northeastern corner of NM. The closer proximity of the high will
slow down the steering flow, and this could lead to some locally
heavy rainfall. Temperatures will be fairly comparable to
yesterday's readings and Roswell could once again eclipse 100
degrees.

On Tuesday, the Pacific Northwest low will move farther inland
while a secondary trough wraps into central CA. The upper high
will be trying to nudge back to the east, but it still appears a
remnant ill-defined centroid could linger over NM. Drier air aloft
would have overtaken much of the northwestern quarter to third of
the state and surface dewpoints could drop a few degrees more in
this area. Otherwise storms would favor the southwestern mountains
and the central mountain chain of NM Tuesday afternoon and
evening.

High pressure then becomes more definitively placed over TX on
Wednesday while the CA trough moves farther inland. Deeper
subtropical moisture, much of which will have originated from
tropical cyclone Javier (the storm formerly known as Earl), will
be steered into Arizona and western NM. Precipitable water values
are advertised to soar back to a general range of 1.0-1.25 inches
Wednesday. The mid level tropospheric flow is quite stiff for
early August with 500 mb flow advertised to be out of the south at
15 to 25 kt. This could introduce some speed shear to vertical
wind profiles, especially in the western zones where some stronger
storms could take shape amidst the juicy atmosphere.

This flux of higher moisture will be battled by shifting winds as
the western U.S. trough moves towards the Rockies on Thursday.
The westerly component will erode the moisture, especially in the
north central to northwestern zones of NM Thursday with storm
chances decreasing there as the day progresses. The dry air will
continue to invade farther into NM into Friday as the trough moves
into the northern plains of the nation. This will send a surface
cold front southward, and this boundary should invade the plains
of NM during the day Friday. While the drier air aloft will be
working in, the surface front will supply the plains and east
faces of the central mountain chain with some higher boundary
layer moisture and upslope forcing, leading to storm potential
that would favor these eastern zones.

Into Saturday the front is projected to plunge west of the Rio
Grande and perhaps just beyond the Continental Divide. This will
keep the central mountain chain favored for storm development,
largely due to upslope flow with a secondary concentration along
and just east of the Divide.

By Sunday, forecast models quickly come to a disagreement with the
GFS depicting a weakness in high pressure over NM with a plethora
of subtropical moisture drawn into the state. The European
contradicts this solution, boasting that high pressure will keep a
presence over the Land of Enchantment, acting as a blockade to
further moisture enhancements.

.FIRE WEATHER...
Some drying northwest and west central today though Tuesday as
southwest flow associated with an upper trough along the west coast
makes some progress into wrn New Mexico. This will reduce the shower
and storm activity somewhat in the west but shift the focus for
wetting rain into the central mt chain and adjacent highlands as
well as portions of the eastern plains. Temperatures to remain above
average through Tuesday and vent rates mostly good to excellent
except for some localized fair to poor values in the southwest today
and west central to north central Tuesday. Storm motion today and
tonight will be mostly from west to east around 10 to 20 mph. Storm
motion Tuesday will be a bit slower and generally from southwest to
northeast.

Models continue to suggest a surge of moisture from Javier aka Earl
could occur Wednesday into Thursday. At this time, the surge looks
to be short lived as a trough passing to our north brings drier and
westerly winds aloft, disrupting the plume. Locales along the
contdvd to the central mt chain may have the best chances for
wetting rain Wednesday through Thursday. Daytime temperatures will
cool in the west, and will be about 5 and up to 10 degrees below
average, while the east will remain a few degrees above normal. Vent
rates Wednesday may be fair to poor across portions of the west, and
through central NM Thursday.

The trough mentioned above will bring drier air to the west Friday,
but an associated front will spark convection in the east, which
will likely push low level moisture back westward into the RGV and
potentially reaching the contdvd by Saturday. Some high Haines
values make an appearance from the RGV westward Friday but end up
retreating toward the contdvd Saturday.

Despite the drying in the northwest/west central through Tuesday as
well as later this week, overnight rh recoveries will remain good to
excellent.

Little confidence in the forecast for early to mid next week. The
GFS progs a return to a monsoonal pattern while the ECMWF would be
relatively dry.
