.SHORT TERM...
(Tonight through Tuesday night)
Issued at 1222 PM CDT Sun Jul 20 2025

Hot and humid conditions are ongoing across the region this
afternoon with a few showers and storms as well. Apparent temps
are just shy of heat adv criteria of 108F except at a few AWOS
sites which have a dewpoint slightly higher than surrounding
sites such as Jasper and Little Pecan Island. As afternoon temps
increase, more sites will likely brush against 108 or surpass
across interior locations. Convection and temps will decrease as
sunset approaches.

Into Monday afternoon temperatures will again climb well into the
90s. A very slightly drier airmass is forecast to advect in with
PWATs dropping from around 1.75" this morning to between 1.25" and
1.5" by tomorrow morning. Less convection and cloud cover is
anticipated from the already minimal activity. The bright side is,
dewpoints may mix out slightly more with apparent temperatures
rising to slightly below 108F. Hi-res guidance indicates dewpoints
may even mix into the 60s across well inland portions tomorrow
afternoon. No such luck closer to the coast, however.

Unfortunately higher moisture will work back in late Monday. The
upper ridge will be about overhead for Tuesday with a heat adv
likely for Tuesday for some or most of the area.

.LONG TERM...
(Wednesday through next Saturday)
Issued at 1222 PM CDT Sun Jul 20 2025

Hot and humid conditions expected again Wednesday.

A slug of deep moisture will be driven west along the northern
gulf coast late in the week around the ridge over the deep south.
Rain chances will ramp up Thursday and remain high into the
weekend. The upside is air conditioners will get a modest break
as temps fall back to the upper 80s to low 90s. Heavy rain is also
a concern during the period.

.AVIATION...
(18Z TAFS)
Issued at 1222 PM CDT Sun Jul 20 2025

Generally VFR conditions are expected during the period, however
brief MVFR ceilings may occur this afternoon with any isolated
shower or storm.

&&

.MARINE...
Issued at 1222 PM CDT Sun Jul 20 2025

Shower and storm activity expected to be at a minimum through the
midweek while light to modest onshore flow persists.

&&

.FIRE WEATHER...
Issued at 1222 PM CDT Sun Jul 20 2025

Minimum RH values will remain high, around 50 to 60% through
Wednesday. Due to high pressure overhead, winds will be light for
the next several days, less than 10 mph. Chances of precipitation
begin to increase across interior locations by Thursday into the
following weekend
