.SHORT TERM...
(This evening through Friday Night)
Issued at 345 PM CDT Thu Jun 27 2024

The ongoing scattered convection should be dissipating early this
evening, although we are likely to still see some isolated activity
around 7-8pm ish across central areas. Expecting isolated to low end
scattered convection on Friday across southeast areas with heating.

Heat indices are near 108 degrees across NW areas early this aft,
and generally 105 to 108 further to the southeast. Likely to need
another heat advisory for tomorrow across W/NW areas again. The
mid/upper level ridge will strengthen and expand early this weekend,
so will likely need an expansion of heat advisories this weekend.

Max temps tomorrow look similar to today upper 90s NW and mid 90s
elsewhere inland. Min temps are expected to gradually increase some
with mins on Saturday morning in the lower 80s coast to upper 70s
inland.

.LONG TERM...
(Saturday through next Wednesday)
Issued at 345 PM CDT Thu Jun 27 2024

Broad mid/upper level ridging persisting and stretching across the
southern US looks to be the main weather feature for the long term
forecast for SE TX. Warm to hot weather will continue this weekend
with little to no POPs. Highs will range from the mid to upper 90s
on Sat/Sun becoming hotter by the start of next week as the lower/
mid level ridge strengthens around the TX/LA border. Triple digits
are going to be possible for much of the FA starting on Mon should
models verify. Heat index values will continue to flirt around Ad-
visory criteria and would not be all that surprised if an Advisory
was already in place over parts/much of the FA by the start of the
long-term period.

Other issues to be aware of for the weekend will include the poss-
ibility of Saharan Dust moving into SE Texas. This could result in
hazy conditions the next several days. Low POP chances are progged
to return by Mon afternoon/early evening. 41
