...New AVIATION...

.SHORT TERM...
(This evening through Tuesday)
Issued at 119 PM CDT Mon Jun 14 2021

This afternoon, satellite imagery and radar imagery show a
Mesoscale Convective Vortex (MCV) moving across Crockett County
as of 1 pm and moving to the southwest. Within the MCV, there are
areas of rain and isolated-scattered thunderstorms, along with
widespread cloud cover. Earlier outflow boundaries and cloud cover
resulted in cool temperatures across the Concho Valley and Big
Country, with the coolest spot being the western Concho Valley
where 1 pm temperatures were only in the mid 60s. Meanwhile, the
Central and Western Big Country counties and eastern Concho
Valley were in the low to mid 70s, while elsewhere to the east
and southeast (and also in Crockett County), clear skies have
resulted in much warmer temperatures in the mid 80s to low 90s.
Due to the better solar insolation (i.e. sunshine) in Crockett
County, conditions are more unstable ahead of the approaching MCV
(ML CAPEs of 1000-1500 J/KG) while the approaching MCV will
continue to provide plenty of lift for additional storms/showers
for Crockett County. In fact, latest radar imagery shows storms
are starting to develop in that region.

Early this evening, storm chances should end for all locations
except for some slight chances in Crockett County, as the MCV
continues to move southwest. Storm chances should end for Crockett
County by mid to late evening as the MCV exits the region. From
then on, we should be dry through Tuesday afternoon. Due to the
slight cooling brought about by the MCV, lows tonight could be
slightly cooler (upper 60s to low 70s).

Tuesday, some warming of the 850 mb thermal ridge and sunny skies
should result in warm highs in the low to mid 90s.

&&

.LONG TERM...
(Tuesday night through next Monday)
Issued at 156 PM CDT Mon Jun 14 2021

We will continue with the mostly hot and dry forecast through the
long term period. Highs will likely remain in the middle 90s to
102. The persistent high pressure ridge may budge some towards day
7, but that is uncertain at this time.

&&

.AVIATION...
(00Z TAFS)
Issued at 610 PM CDT Mon Jun 14 2021

VFR conditions for the next 24 hours. Winds will be light and
variable overnight, becoming predominantly northeast at 8-10KT
during the daytime.
