.DISCUSSION...
(Tonight through next Tuesday)
Issued at 1210 AM CDT Tue Jul 7 2026

Convection has dissipated through the past evening, however
nocturnal showers may redevelop over the coastal waters and along
the coast through early morning.

The forecast reasoning hasn't changed much over the past few days.
The subtropical ridge remains stretched from the Atlantic into the
gulf. This is keeping a light onshore flow locally. Aloft, a
weakness stretches along the mid-Mississippi Valley into west LA 
and east TX. This is between an upper ridge over the SW Atlantic
and another ridge centered over the Rockies.

The two upper ridge will bridge the gap over east TX and west LA
through the second half of the work week. Rain chances will
decrease today from the prior two days, however isolated to widely
scattered convection is still anticipated this afternoon. Slightly
lower chances are expected Thu and Fri.

This weekend the ridge over the Rockies will build northeast and
into the northern plains by Monday. As the ridge lifts northeast,
a weakness aloft will once again develop over the norther gulf
coast. Thunderstorm chances will once again increase.

Temperatures will remain near climo norms for the date through the
period.

.AVIATION...
(18Z TAFS)
Issued at 1212 PM CDT Wed Jul 8 2026

Scattered showers and thunderstorms will continue along/south of
the I-10 corridor into this evening, possibly expanding further
north later this afternoon as well. Like the last few days, if any
of these storms pass over the terminals they will be capable of
producing heavy downpours that cause reductions in VIS along with
frequent lightning. Outside of these storms, VFR conditions and 
light and variable winds should prevail throughout the forecast 
period.

.MARINE...
Issued at 1210 AM CDT Tue Jul 7 2026

High pressure will remain stretched from the Atlantic into the
gulf through the weekend. This will keep a light onshore flow in
place. Isolated to widely scattered nocturnal showers and storms 
will be possible each morning.

&&

.FIRE WEATHER...
Issued at 1210 AM CDT Tue Jul 7 2026

No fire weather concerns at this time. Isolated to widely
scattered storms are expected today along the sea breeze, however
coverage will decrease Thursday and Friday as an upper ridge
builds in.
