Area Forecast Discussion
National Weather Service Midland/Odessa TX
603 AM CDT Tue Apr 25 2017

12Z TAF issuance
Very windy conditions expected to commence later this morning and
last through the afternoon. Winds could gust over 40 kts at
times, especially at the western terminals. A cold front will turn
winds to the northwest after sunset and expect it to remain gusty.


.PREV DISCUSSION... /issued 502 AM CDT Tue Apr 25 2017/


Little changes to the current forecast, and another day of wind and
fire visit West Texas and Southeast New Mexico.  WV imagery shows an
upper trough over WY, w/a secondary trough over SE OR that is
forecast to phase w/the first and move thru the Texas Panhandle by
12Z Wed.  This will result in increasing westerlies across much of
the area today and tonight.  The NAM develops a fairly strong mtn
wave signature over the Guadalupes thru around 03Z Wed, and H7
height gradients tighten up to 70m/200nm.  Forecast NAM soundings
show mixing over the Guadalupes to 650mb, where 50kt westerlies are
forecast, whereas the GFS mixes to 625mb w/55kt westerlies.  As
usual, the wild card will be sky cover, as models take a 300-500mb
slug of moisture over the area today.  However, confidence is high
enough to issue high wind warnings for areas that were in a watch
yesterday, as well as advisories further east out onto the plains.
W/temps well-above normal, RH will be in the teens or lower,
increasing the fire wx threat for much of the area.  See Fire Wx
Discussion below for more detail.

Unfortunately, a cold front will accompany the upper trough, and
move thru Wednesday, w/fropa at KMAF around 14Z.  This will take
temps Wed afternoon down to a couple of cats below normal.  However,
westerly sfc flow resumes Thursday under a broad trough covering
most of the CONUS, and downslope warming should allow for a rebound
to above-normal temps.  This could be another windy day out west,
but we`ll forego a watch attm to keep things simple, and just
mention it in the HWO.

As the weekend approaches, a tertiary trough will approach, and move
thru the region by 00Z Sun.  This suggests more winds beyond Thu,
and will result in a chance of convection beginning Friday night and
lasting thru Saturday night. Temps will drop below normal Sat/Sun,
and rebound to above-normal Mon/Tue.


Very hot, dry, and windy conditions will lead to extreme fire danger
and critical fire weather conditions across much of the area today.
Green-up from the Permian Basin south to the Big Bend will temper
the threat there, but areas to the west still have mostly cured
vegetation. Locations from the Guadalupe and Davis Mountains into SE
NM also will have the strongest winds so have upgraded to a Red Flag
Warning here. RH`s will drop mostly into the single digits this
afternoon while winds increase from the west at 25 to 35 mph with
gusts over 40 mph.

A cold front will bring some relief Wednesday, but critical fire
weather conditions are still possible across the Davis Mountains and
Marfa Plateau. Widespread critical fire conditions look to return
Thursday and Friday ahead of yet another strong storm system.
