.SHORT TERM...
(Today through Wednesday night)
Issued at 309 AM CDT Mon Aug 12 2024

A stalled and diffuse frontal boundary remains along the coast
early this morning. North of the front dewpoints are still in the
mid 70s to upper 60s while coastal areas are in the mid to upper
70s. Aloft a ridge remains centered over Texas.

Today the weak front will gradually lift back north while washing
out. Moisture will once again surge north with dewpoints gradually
increasing, but most notably over the interior locations with not
much change expected along the coast. High temps will climb into
the 90s. This combined with dewpoints in the 70s will produce
apparent temperatures in the 100s. Locations in SE TX may even
bump up to near heat adv criteria for an hour or two this
afternoon. Also with the return of moisture a few showers or
storms may be possible along the sea breeze.

The upper ridge is expected to remain in place Tuesday and
Wednesday suppressing convection, however a isolated to widely
scattered shower may occur along the sea breeze. The main concern
through mid week will be the heat. With the return of higher
dewpoints and remaining upper ridge, apparent temps are forecast
to climb into the 105 to 110 range each afternoon.

.LONG TERM...
(Thursday through Monday)
Issued at 309 AM CDT Mon Aug 12 2024

During the long term the region will remain stuck in a stagnant
pattern with an upper ridge in place and gulf moisture streaming
across the region. Isolated sea breeze showers may be possible,
but very little cooling is anticipated from this afternoon
convection. Hot and humid conditions are expected.
