.SHORT TERM...
(Friday through Saturday)
Issued at 350 AM CDT Fri Jul 12 2024

Typical mid-July weather is expected to continue into this weekend
as we remain flanked by the upper-level ridge out west across the
Four Corners Region and another ridge extending over much of the
SE CONUS. Therefore, persistence is generally expected to prevail
with near to slightly above average temperatures mostly in the mid
90s and a few isolated areas in the upper 90s. Not surprisingly,
this will lead to a return of heat headlines by this weekend with
at least some portions of the region likely reaching heat advisory
criteria on Saturday as Gulf moisture continues to push dew points
higher. Likewise, overnight temperatures will also trend warmer as
well with mostly lower to mid 70s areawide.

As for rain chances, they will be diurnally driven and limited to
our far southern zones this afternoon during peak heating hours.
Slightly higher chances are expected on Saturday with a stronger
sea breeze push, possibly allowing for isolated convection as far
north as the I-20 corridor. However, the main weather story will
continue to be the building heat and humidity through the weekend
and beyond into next week.

.LONG TERM...
(Saturday Night through Friday)
Issued at 350 AM CDT Fri Jul 12 2024

Continuing with the weather theme in the short-term, look for heat
headlines to expand across more of the region by late this weekend
into early next week. Rain chances remain limited with isolated to
widely scattered afternoon showers and thunderstorms possible on
Sunday before largely diminishing by early to mid next week as the
upper ridge becomes even more dominant. Afternoon high temperatures
will generally range in the mid to upper 90s through at least mid
week before some relief arrives toward the end of this forecast
period.

This heat relief is expected to come by way of a rare mid-summer
cold front arriving on Thursday. Medium-range model progs are in
fairly solid agreement on advancing this front deep into our area
through the end of next week with increasing chances for showers
and thunderstorms. Additionally, temperatures will return closer
to seasonal averages along with drier post-frontal air helping to
bring an end to the heat and humidity expected earlier in the
week.

brief BR around daybreak. Light sfc winds around 5KT from the SE
with low level flow also from the S/SE, but backing to E/NE abv
5kft all 10-20KT. We should be fair in the morning with few cu and
