.DISCUSSION...

See 18Z Aviation Discussion below.

.AVIATION...

Westerly winds continue next 24 hours, becoming gusty this
afternoon as an upper trough passes to the north. MVFR
visibilities will be possible this afternoon due to BLDU.
Otherwise, VFR conditions will prevail. A few high clouds are
anticipated.

DISCUSSION...
See 12Z aviation discussion below.

AVIATION...
Very windy conditions expected to develop this afternoon with west
winds gusting to 40kts. Visbilities may be reduced to MVFR with
BLDU at some of the TAF sites, but the main question is how much
recent rains will keep the dust from blowing. For now will only
restrict VIS below VFR at CNM where winds will be strongest, and
make mention of 6SM BLDU at MAF/HOB. Winds will diminish after
sunset.

PREV DISCUSSION... /issued 427 AM CST Thu Feb 23 2017/

DISCUSSION...

.A very dry, warm and windy day ahead for most areas, leading
to critical/extreme fire weather conditions across some areas.
Please see the Fire Weather section below for more details...

An upper trough, currently swinging through the Rockies, will slowly
move into the Central Plains today with strong upper winds moving
overhead. Meanwhile, a lee surface trough will continue to deepen
across eastern CO resulting in a tightening surface pressure
gradient through NM and W TX. West winds will increase by mid
morning as the pressure gradient tightens then as mixing commences
shortly thereafter, winds will increase further as stronger winds
aloft mix down toward the surface. Will likely see the highest winds
across the Guadalupe and Davis Mountains and the SE NM Plains and a
High Wind Warning is in effect for these areas mid morning through
early evening. Farther east and south, winds look to be slightly
weaker so will go with a Wind Advisory for the Van Horn and HWY 54
Corridor, Davis Mountains, the Trans Pecos region and much of the
Permian Basin. A few of these locations will likely see high end
Advisory and potentially a brief period of High Wind but it should
be fairly isolated. The potential for blowing dust remains therefore
will keep mention in the forecast for this afternoon. Wind speeds
will diminish after sunset however high winds look to persist across
the Guadalupe Mountains overnight through Friday morning so will
continue the Warning for this area. Otherwise, temperatures will
once again warm to near record highs today with readings in the mid-
upper 80s across much of the region.

Not as windy Friday however somewhat breezy conditions and
temperatures roughly 15 degrees cooler can be expected. A cold front
Saturday will knock temps down a bit further but this will be short-
lived with the return of strong westerly, down-sloping winds by
Sunday and high temperatures will rebound into the 70s. Warm and dry
conditions will persist and there is a good possibility for
critical/extreme fire weather conditions once again Sunday and next
Tuesday with gusty west winds forecast each day.

FIRE WEATHER...
Extremely critical fire weather conditions are still expected across
much of the area today as an upper level trough moves across the
Rockies. This trough will increase west winds today before veering
from the northwest tonight as a cold front moves through the area.
The front will bring cooler temperatures tomorrow, but very dry air
will still remain and winds behind the front will reach 20 mph in
southeast New Mexico, the Guadalupe and Davis Mountains and adjacent
plains so have issued a Fire Weather Watch. A second shot of cooler
air arrives Friday night ending the critical fire weather threat for
at least a day before winds begin to increase again Sunday.
