Area Forecast Discussion

...New SHORT TERM, LONG TERM, MARINE...

.SHORT TERM...
(Today through Sunday Night)
Issued at 302 AM CDT Sat Aug 17 2024

Surprise...it`s going to be hot.

Hot and humid conditions prevail through the weekend, courtesy of
the mid-upper level ridge that has been building to the west and a
surface high pressure to our east bringing in moisture from the Gulf
of Mexico. Persistent onshore winds in concert with daytime heating
and the sea/bay breezes will bring a lucky few some relief as
isolated showers and thunderstorms form and move inland. Once again,
any activity is expected to taper off by or shortly after sunset.

Highs will top out in the 90s to around 100F today and Sunday. The
combination of heat and humidity will result in heat index values
from 105 to 112F. Some areas could reach to 115F. The Heat Advisory
continues through this evening, and will likely be extended through
the weekend.

.LONG TERM...
(Monday through Friday)
Issued at 302 AM CDT Sat Aug 17 2024

Mid-upper ridging to our north and west will continue to dominate
area wx with heat advisories likely being required into the
early-mid parts of next week. That said, there is a bit of hope
that portions of the area will see the potential for some isolated-
scattered precip in the Tue-Thur time period as a diffuse backdoor
frontal boundary tries to advance into parts of the CWA from the
east. Subsidence will still be a substantial limiting factor, but
it appears the center of the ridge might reposition itself just a
bit further west and allow for this possibility (along with high/low
temps relenting 2-5F from what we`ve seen as of late).

The ridge should then move back into the Southern Plains Friday
into the weekend. Some guidance shows a portion of the East Coast
trof breaking away from its parent trof further north and tracking
under the ridge toward the Western Gulf coast. If so, some rain
chances might continue across southern parts of the CWA. 47
