AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1048 PM CST Sun Dec 21 2014

.DISCUSSION...

Please see the 22/06Z aviation forecast discussion below.

.AVIATION...

A breezy VFR night across all terminals this evening. Westerly
winds at the surface will forbid a return to MVFR or less
cigs/vsbys, and all we`re expecting tonight is sct-bkn cirrus.
Winds will increase a bit in the mid morning hours as a pre-
frontal trough passes through. After sunset, winds will slack off
a bit. Will keep them southwesterly for now, but should veer
gradually to a northerly direction after this TAF period. Look for
deteriorating wx conditions after 06Z tomorrow night as a upper
level storm system approaches the southern High Plains.

.PREV DISCUSSION... /ISSUED 843 PM CST Sun Dec 21 2014/

UPDATE...

Update to issue a High Wind Warning for the Guadalupe Mountains
tonight.

DISCUSSION...

Northwest flow aloft will continue to increase over the region
tonight and Monday as an ua trough deepens over the central U.S.
Plains.  Although the H7 wind direction, northwesterly, is not
favorable for strong winds in Guadalupe Pass, these mid level winds
appear strong enough for high winds to occur in the higher
elevations of the Guadalupe Mountains.  In addition, the surface
pressure gradient has increased across the Guadalupe Mountains and
has yielded high winds through Guadalupe Pass for the last couple of
hours.  Since the above is expected to continue through the night,
will issue a High Wind Warning for the Guadalupe Mountains tonight.
The warning will be in effect until 4 am CST, which will allow
the next shift to assess whether the warning will need to continue
through Monday.
