.SHORT TERM...
(Today through Wednesday night)
Issued at 1221 AM CDT Mon Jul 14 2025

An upper low remains centered over the northwest gulf while a
ridge is centered over Alabama. Between these systems a somewhat
divergent patter is over the local area. At the surface a ridge is
over the northeast gulf which is keeping the onshore flow in
place across LA and SE TX. A weak area of low pressure is east of
FL and GA.

A few nocturnal showers or storms will continue to driven inland
through the early morning hours around the periphery of the ridge.
With the lack of ridge aloft, scattered afternoon storms can be
anticipated, however with a slightly less coverage as the upper low
shifts west and weakens. Temperatures today will be near the climate
normal for the date.

A heat wave is anticipated Tuesday and Wednesday as the upper ridge
over the southeast states shifts west. This will serve to decrease
rain chances and increase temps a few degrees. Apparent temperatures
across inland may reach the threshold of 108F both Tue and Wed
afternoons, however guidance continues to show that this is spotty.
Trends will continue to be monitored.

.LONG TERM...
(Thursday through Monday)
Issued at 1221 AM CDT Mon Jul 14 2025

The area of lower pressure east of Florida may be the main focus
during the extended. The trough is forecast to move across Florida
and the northern gulf through the short term then potentially in the
north central gulf coast around Thursday. At a minimum rain chances
will increase for the local area as the slug of deep tropical
moisture moves in then lingers into or perhaps through the coming
weekend. While guidance is a bit split on the eventual evolution of
the low pressure area late in the week, guidance does agree that it
may be a wet period with the potential for heavy rain.

.AVIATION...
(06Z TAFS)
Issued at 1221 AM CDT Mon Jul 14 2025

.MARINE...
Issued at 1221 AM CDT Mon Jul 14 2025

High pressure extending across the northern Gulf will maintain
light onshore winds and low seas through late next week. Daily
scattered showers and thunderstorms will continue over the coastal
waters through Monday with lower rain chances Tuesday and
Wednesday as upper level ridging builds across the northern gulf.

&&

.FIRE WEATHER...
Issued at 1221 AM CDT Mon Jul 14 2025

Light southerly winds will maintain dewpoints in the mid to upper
70s through the week. Afternoon minimum relative humidity values
are expected to range from 50 - 70%. Diurnal thunderstorms will
develop from late morning through early evening today, however an
upper level ridge building into the region will lower daily rain
chances Tuesday and Wednesday.
