Area Forecast Discussion
National Weather Service El Paso Tx/Santa Teresa NM
238 AM MDT Sun May 26 2019
.SYNOPSIS...
A deep low pressure system with a cold front will be moving
across the southwestern United States today and Monday. This storm
will bring windy conditions with blowing dust across southern New
Mexico and west Texas today and again on Memorial Day followed by
cooler temperatures on Tuesday. Seasonably warm mostly dry
weather is expected over most of the Borderland Wednesday through
next weekend. However there will be slight chances for
thunderstorms for areas mainly east of El Paso Thursday night and
Friday.
&&
.DISCUSSION...
Active weather expected the next two days. Early this morning
unseasonably deep high amplitude upper trough axis was aligned
from Washington southward all the way into southern Baja with an
embedded deep closed low centered over northern California. The
upper low will drop further southward into southern
Nevada/southern California by early this evening while short
wave/impulse ejects to the northeast ahead of main system into New
Mexico and far west Texas. Downslope winds will concurrently
support lee surface troughing through eastern New Mexico. Overall
pattern will cause low and mid level gradients to strengthen
today. In addition diurnal warming plus inflow of warm dry air
will result in dry lapse rates from the surface to around 550 mb
allowing higher winds aloft to mix downward. These factors will
combine to bring windy conditions this afternoon and this evening
with current wind advisories looking on target.
Upper low will move to the northeast across northern Arizona into
Colorado Monday and Monday night with attendant dynamics causing
unseasonably deep lee cyclogenesis over eastern Colorado where 989
mb surface low develops. Strong low and mid level gradients will
therefore persist with windy conditions again occurring Memorial
Day. An associated weak Pacific cold front will also move eastward
across the CWA later Monday resulting in Tuesday temperatures
cooling to around 5 degrees below normal.
Upper low moves into the northern plains on Tuesday while trailing
trough axis hangs back to the southwest through Arizona. This
disturbance will move across the CWA on Wednesday but have no
significant impacts. Associated westerly flow will sustain dry
weather with warming temperatures Wednesday and Thursday.
Low level easterly winds develop over eastern portions of the CWA
Thursday with advection of a more moist unstable air mass.
Consequently a few showers and thunderstorms are outlooked for
eastern zones Thursday night and Friday. Otherwise westerly flow
will bring seasonably warm dry weather to most locations Friday
through next weekend.
&&
.AVIATION...26/12z-27/12z.
Wind gusts from 40-50KTS will cause areas of visibility less than
2 miles in blowing dust mainly from 18z-02z. Skies mostly SCT-BKN
100-200.

.FIRE WEATHER...
A deep low pressure system with a cold front will be moving
across the southwestern United States today and Monday. This storm
will bring windy conditions with blowing dust across southern New
mexico and west Texas today and again on Memorial Day followed by
cooler temperatures Tuesday. The combination of warm
temperatures...low humidity and especially wind gusts around 40 to
50 mph will bring widespread Red Flag conditions today and again
on Monday. Seasonably warm mostly dry weather with lighter winds
are expected over most of the region Wednesday through next
weekend. However there will be slight chances for thunderstorms
for areas mainly east of El Paso Thursday night and Friday.
