Area Forecast Discussion

.DISCUSSION...

.AVIATION...

Winds will become very gusty out of the southwest this afternoon
before subsiding this evening. Blowing dust will be possible with
the strong winds; otherwise, VFR conditions will prevail.

.PREV DISCUSSION... /issued 313 AM CST Tue Feb 28 2017/

DISCUSSION...
Strong sw flow aloft will move across the area today resulting in
high wind warning and wind advisory conditions across the west and
central/northern areas, respectively. A 7h height gradient of 70dam
mostly supports this while a well developed upstream tilted OMEGA
couplet across the GDP Mtns supports a mtn wave. Satellite does
depict an area of extensive clouds moving into the area (supported
in forcast soundings too) which will limit mixing "some", enough for
us to keep high wind warning confined the western areas. We will opt
to extend wind advisory into Borden/Howard Co though. 85h temps and
downslope wind mostly supports the high temp forecast of M70-U70s SE
NM to mostly 75-85 remainder of the area. Blowing dust is already
in the forecast and based the blowing dust that occurred last
Thur this seems like a foregone conclusion. A cold front will
follow Wed AM and temps will turn cooler, closer to normal, as
surface high pressure hold in place til Thur/Fri. Noticeably
warmer Sat, especially across the w, and expanding east Sun/Mon.
GFS hints at light precip next Sun/Mon across the far SW, we
expect will be transitory.

FIRE WEATHER...
Factors for critical/extremely critical fire wx conditions continue
to come into alignment today. A powerhouse mid level wind field of
40-60kts and 75-90kts within 7h-5h SW flow, respectively, will rake
the area. Said strong mid level winds will intersect the fire
effective low level thermal ridge just off the Caprock at the
surface and on the high plains at 85h.  Meanwhile the lowest surface
dewpoints will push hard into the windward side of the 85h thermal
ridge around 21Z today. High temperatures will be about 10-15
degrees above normal and with downslope winds minimum RHs will
fall below 10% in a few areas. SW-W winds of 25-35 mph will be
common this PM with even stronger winds across SE NM/parts of the
Trans Pecos. Fire danger will be widespread extreme today,
reflective of the dry grass/wind/low RH. 10hr/100hr fuels have
moved into the 75th percentile across most areas with a few spots
just into the 90th percentile, the driest this area has been in
quite a while. The overall result is a solid moderate Significant
Fire Potential, the likelihood for Initial Attack is high. Also
the fire weather as indicated the RFTI will fall into the high end
critical (6-7)to extreme(8) range. In the past wx patterns such
as this have resulted in the multiple occurrence of large
destructive fires. As such local officials should be prepared for
possibility of increased resource usage/need. Shading from
clouds/blowing dust will be an inhibitive factor.
