.SHORT TERM...
(Today and tonight)
Issued at 216 AM CDT Fri Jul 21 2023

An area of lingering showers and thunderstorms is expected to exit
northeast parts of the area by late morning. Otherwise, a cold front
will continue to push south through southern Oklahoma into north
Texas this morning with a nice cool down in its wake across much of
the area today. Most locales will be some 10 to perhaps 15 degrees
cooler than what was seen Thursday. Drier air will also filter south
across the area giving a short respite from the humidity.

By late today another area of storms is expected to develop across
northeast New Mexico into northwest Texas. Although much of this
activity is expected to remain west of the area, there is a small
chance for this activity to make a run at far southwest Oklahoma and
western north Texas Friday night. With the drier air in place
overnight low will drop into the low to middle 60s across much of
the area with a few upper 50s across the north.

.LONG TERM...
(Saturday through Thursday)
Issued at 216 AM CDT Fri Jul 21 2023

Northwest flow does look to continue through the weekend, but most
models either keep the precip along with higher terrain to our west
or to our northeast. As we go into next week, upper ridge builds
east, bringing and end to the chances for overnight MCS across the
area. There remains some differences between the GFS and ECMWF on
how aggressive the upper ridge exspansion eastward, but the sensible
weather is similar with a gradual warming trend and very little if
any rain chances through the work week. will have to watch trend in
moisture and associated afternoon heat indices as additional heat
headlines may be needed at some point next week.

Issued at 1024 PM CDT Thu Jul 20 2023
