Area Forecast Discussion
National Weather Service El Paso Tx/Santa Teresa NM
1212 PM MDT Mon May 21 2018

.SYNOPSIS...
Moist unstable air will flow into southern New Mexico and west
Texas this afternoon and tonight. As a result there will
thunderstorms across much of the region with large hail, damaging
winds and heavy rains falling over some locations this afternoon
and tonight. More thunderstorms are expected on Tuesday mainly
east of the Rio Grande with dry seasonably warm weather elsewhere.
Westerly winds will produce mostly dry weather with very warm
temperatures Wednesday through early next week.

&&

.DISCUSSION...
Low level east to southeast winds are transporting moist unstable
air into much of southern New Mexico and west Texas early this
afternoon with surface dewpoints above 50 F as far west as Deming
as of noon. Thus air mass rather unstable with MUCAPES already
from 1000 to 2000 J/kg. Upper low was meanwhile located over
southern Nevada and weak short waves are expected to eject ahead
of it to the northeast across the southern Rockies with these
features acting as possible storm initiation mechanisms. In
addition convective inhibition was minimal with surface heating
possibly initiating updrafts. Finally upslope flow will likely
force storms over high or sloping terrain. Thus deep convection
expected across at least eastern half of the CWA with storm
outflows also sustaining activity into the evening.

Southwest winds around 35 kt will support 0-6 km shear from 30 to
40 kt which in turn will enhance and sustain updrafts. Wet bulb
zero heights were also rather low below 9000 feet agl while DCAPE
values were above 1300 J/kg for much of the region. These factors
indicate risk of severe thunderstorms with large hail and
damaging winds. Abundant low level moisture inflow/flux will also
support isolated storms producing very heavy rains with a flash
flood threat.

The upper low will drift slowly east the next several days which
will cause low level winds to gradually become more southwesterly
from west to east. Consequently expect moist unstable air and
thus thunderstorms will be confined mostly eastern Otero and
Hudspeth Counties Tuesday through Thursday followed by warm dry
weather all locations Friday through next Monday.

.FIRE WEATHER...

Following a change of air mass last night and a switch to SE winds,
Gulf of Mexico moisture continues to stream into our area. An upper
level low pressure system continues to develop over southern
California. This will provide a moist unstable environment to set of
thunderstorms this afternoon and evening, developing near the Rio
Grande in New Mexico and increasing in coverage as they spread
eastward. Some storms may produce damaging winds and large hail.
Drier conditions are expected for much of rest of the week with
temperatures climbing back into the 90s by Wednesday, and maybe
approaching the 100 degree mark in the lowlands heading into the
weekend.
