Area Forecast Discussion
National Weather Service El Paso TX/Santa Teresa NM
346 AM MST Fri Feb 24 2017

.SYNOPSIS...
Mostly Sunny skies will prevail today, with temperatures running
just a couple degrees below normal. A fast-moving upper level
disturbance will bring breezy to windy conditions back to the area
on Sunday afternoon, with a slight chance of showers over the
higher terrain of the Gila Region. Another disturbance will bring
similar conditions to the area Tuesday.

&&

.DISCUSSION...
Downslope winds east of the Franklins and Organs started creeping
back up after midnight, as expected, but have fallen a little short
of expectations. The highest gusts have been fairly close to the
US-54 corridor where gusts peaked in the 45 to 50 mph around 1 AM.
Obs from WSMR`s SAMS network have dropped out, so really have no
idea what is happening east of the Organs. With winds still
gusty in NE El Paso, decided to downgrade the High Wind Warning to
a Wind Advisory rather than cancel it outright. It still expires
at 6 AM.

Otherwise, expect a fair day today with breezy W to WNW winds.
Temperatures will run about 2-3 degrees below climo normals.

Bigger picture - overall pattern features long wave trough over
the Canadian Prairies and northern high plains. This feature will
stretch out east-west over the weekend, resulting in zonal flow at
the base of the trough over most of the southern states. Westerly
flow will favor a slow warm-up heading into Saturday. A fast-
moving and fairly weak upper-level shortwave trough will pass
through NM Sunday afternoon, bringing a scant chance for showers
to the Gila Region, and elevated westerly winds again. Winds could
reach Advisory-level along east slope locations and possibly in
the Sacramento Mountains as well. Considering the dust plumes/
channels observed yesterday (Thu) over Lordsburg Playa (even with
wind gusts only in the 30-35 mph range), added Areas of Blowing
Dust to the Wx west of Lordsburg Sunday afternoon.

A series of weak disturbances look to affect the area Tuesday
through Thursday with breezy conditions likely Tuesday, followed
by a very weak Pacific cold front Tuesday night, and a low-level
easterly push by Wednesday morning resulting in cooler (slightly
below normal) temperatures for Wed afternoon.

&&

.AVIATION...
Few wind gusts early this morning up to 35 KT possible east of the
Organ/Franklin mountains (including KELP). Otherwise, VFR
conditions with breezy to windy West and WNW winds returning in
the afternoon (16-22KT with gusts around 30 KT, highest east of
mountain ranges).

&&

.FIRE WEATHER...
Very dry conditions expected today with dewpoints in the single
digits in the lowlands, and negative single digits in the higher
terrain above 6,000 feet. Winds will increase again this
afternoon, reaching critical values in a few lowland areas. Will
let the morning Fire Weather forecaster make the final call on Red
Flag (Fire Wx Watch already in effect). May be tough to meet the
3-hour criteria in some areas. Critical Fire Wx conditions
possible again on Sunday as windy conditions return. Dewpoints
will moderate by then, but Min RH values will be close to critical
thresholds again.
