.SHORT TERM...
(Today through Tuesday afternoon)
Issued at 225 AM CDT Mon May 20 2024

Most locations saw their first 100 degree temperature of the season
yesterday and will likely see another today. An LLTR will extend
from Mexico across our region north to the Panhandles with 850 mb
temperatures >31C. Similar to yesterday, highs will soar into the
100s across much of the area with the hottest conditions again
along the Rio Grande (~115F). The Heat Advisory has been extended
through today for the Davis and Chisos Mountains and along the Rio
Grande in lower Brewster county. Another mild night is in store
tonight with lows in the 60s/70s. A shortwave will pass well to
our north Tuesday bringing a weak Pacific front through the area.
While it will remain hot, highs will come down a few degrees with
most locations along and north of I-20 avoiding the century mark.
Further south it looks like more of the same and the Heat Advisory
may need to be extended yet another day for the Big Bend. Still
not seeing any chance for rain through the early week.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 225 AM CDT Mon May 20 2024

Normally, a "cold front" would be welcome phrase after a period of
unseasonable warm temperatures, but unfortunately this front will be
anything but cold.

A backdoor cold front will shoot down into the Panhandle on
Wednesday, likely reaching the northern CWA by early Wednesday
afternoon. At this point it will be pushed back northward with warm
southwesterly flow winning out, and temperatures across the northern
Permian Basin will only be a few degrees cooler compared to Tuesday,
in the low 90s. Elsewhere, highs in the upper 90s/low 100s will
continue, with 110+ along the Rio Grande where another Heat Advisory
will likely be needed. While the front is pushed out of the region,
a disturbance moving across may be sufficient for a few storms to
develop in the far eastern Permian Basin, but moisture will be the
limiting factor here and storm develop will depend greatly on the
location of the dryline. The ECMWF is the most aggressive with
storms Wednesday afternoon, but both of the global models have
pulled back on precipitation chances in the latest run. Waiting on
better consistency, have maintained at least low POP chances for
both Wednesday and Thursday, but chances seem to dwindling for mid-
week storms.

Weak ridging builds back in Thursday and beyond with a thermal ridge
axis displaced just west of the region. With a similar pattern to
this week, multiple rounds of shortwaves will pass to the north, and
compressional warming with downsloping winds will continue to push
temperatures higher and higher each day, and parts of the Permian
Basin may once again hit the 100s by the weekend.
