.SHORT TERM...
(Today through Saturday afternoon)
Issued at 111 AM CDT Fri May 31 2024

Weak shortwave aloft will track across the TX panhandle and DFW
region overnight into Friday morning, allowing ongoing convection
to conglomerate into upscale, mesoscale growth and adjust storm
propagation to a more southerly motion. MCS likely to form early
Friday morning across much of northern Texas with a cold front
moving south along the leading gust front of this system. Main
threat with Friday morning`s storms will be gusty winds along the
leading line of storms, generally between 6-10 AM for the
Snyder/Big Springs area. Storm threat should come to an end for
all local zones by noon.

Cooler temperatures tomorrow behind frontal passage in the
morning. Afternoon temperatures topping out in the upper 80s for
the northeastern Basin, mid-to-upper 90s for the Trans-Pecos
region. Cooler surface air and a strong capping inversion at 750
mb will greatly hinder afternoon storm chances. East surface winds
cutting off the tap of Gulf moisture is another factor limiting
storm chances. A few evening storms will be possible along the
northern fringes of our forecast area (closer to Lubbock) with
convection that forms in southeast NM, otherwise we`ll stay dry
through this afternoon and evening.

.LONG TERM...
(Saturday night through Thursday)
Issued at 111 AM CDT Fri May 31 2024

00Z GFS resolving a shortwave ridge on Saturday, with embedded
waves within the prevailing zonal flow aloft. Surface flow
shifting back to the southeast will reinforce moisture flux and
thus allow for another uptick in thunderstorm chances area wide.
Best chance will be during the late-evening hours with initial
convection developing off to the west and tracking eastward and
subsequent upslope flow allowing storm coverage to grow headed
into Saturday night. PWATs 150% of normal would suggest efficient
rain makers and the risk of areal flooding as storm coverage
increases Saturday night.

Strengthened southwest flow ahead of a subtropical jet streak
will mix out the dryline boundary across the Trans-Pecos region on
Sunday, shifting the boundary further east closer to Midland. We
may see a few isolated storms result further east as a result, but
much lower PoPs expected due to this influx of drier air from the
west. Deep westerly flow take hold of the whole area Monday as a
strengthening upper high over northern Mexico begins a warming
trend. The northward shift of this high pressure will result in
very hot day start to next week with triple-digit highs Monday-
Wednesday. Some relief from the heat seems possible late in the
week with a deep low pressure system over the northern Plains and
subsequent cold front spilling south into the Texas panhandle. NBM
temperatures spread varies greatly regarding the eventual
southern extent of that cooler air, with the ECMWF featuring a
much sharper trough. Model confidence in the position of the upper
high is low at this time, so will settle with the NBM`s modest
cooldown and low-end PoPs for now.

.AVIATION...
(12Z TAFS)
Issued at 643 AM CDT Fri May 31 2024

Generally VFR conditions expected through period. Patchy BKN-
OVC030 from old outflow..mainly north and east of Ft. Davis.
Clouds mainly dissipating by around 15Z-17Z. Surface winds
east/northeast 10-15G25 knots turning southeast 12-17G27 knots
after 00Z.

.FIRE WEATHER...
Issued at 111 AM CDT Fri May 31 2024

Elevated fire danger west of the dryline on Friday, including
most of the Davis Mountains, Guadalupe Range, and Eddy County
Plains. Min RH 5-12% and east winds 10 to 15 mph. ERCs remain
quite high above the 90th percentile in those areas.

Lightning starts will be possible on Saturday as the dryline
shifts further west and thunderstorm chances across much of west
Texas and southeast New Mexico will pose a risk for the elevated
terrain and forested areas. Conditions dry out quickly again
early next week with stronger west flow and warmer temperatures
due to the strengthening of high pressure aloft. Critical
conditions possible Monday/Tuesday if forecasted winds remain
breezy.
