.SHORT TERM...
(This evening through Thursday Night)
Issued at 251 PM CDT Wed Sep 18 2024

A rinse and repeat forecast...ridging aloft and at the surface will
continue to dominate the pattern through the short term period. Hot,
humid and mostly dry conditions will continue with highs generally
in the mid 90s, and afternoon heat indices into the 100 to 107 degF
range. Low-level moisture, light variable winds and mostly clear
skies will once again result in areas of fog overnight through early
Thursday morning, and then again Thursday night into Friday.
Overnight lows in the 70s can be expected. In terms of rain/storms,
a corridor of PWs into the 1.8 to 2.0 inch range (per NAM/GFS) are
progged near Matagorda/Palacios region, extending offshore over our
Gulf waters. This surge in low-level moisture will likely bring a
few light showers along the coast in the morning, and very isolated
activity inland along the seabreeze.

.LONG TERM...
(Friday through next Tuesday)
Issued at 251 PM CDT Wed Sep 18 2024

Long term forecast looks to remain mostly dry with temperatures stay-
ing above normal through the upcoming weekend. This strong mid/upper
ridge currently in place over the state will be persist into Sat/Sun.
A dry warm SW flow at the lower and mid levels will help keep things
quiet with highs in the mid 90s for most locations...otherwise lower
90s are possible.

We could see some low rain chances return for the start of next week
as a series of mid/upper level shortwaves moving across the Northern
and Central Plains helps to flatten the ridging over the region. The
return of deeper onshore winds (and moisture) could give us a slight-
ly more active seabreeze for Mon/Tues. Best rain chances should stay
near the coast. Highs are going to remain on the warm side (from 2-4
degrees above normal)...in the lower 90s. Overnight lows through the
period should range from the lower to mid 70s inland...upper 70s at/
along the immediate coast. 41

(06Z TAF Issuance)
Issued at 1128 PM CDT Wed Sep 18 2024

Late evening surface observations and satellite imagery indicates SKC
at area TAF sites. Still have possible MVFR/IFR cigs/vsbys developing
overnight. Any low cloud and/or fog that do develop will eventually
lift and dissipate after sunrise and will leave the sites VFR in the
late morning thru early evening hours. Most spots will see mainly SE
winds increasing to 5 to 10 knots in the afternoon. Decreasing winds
and VFR tomorrow evening. Looking at another chance of low cigs/vsbys
developing tomorrow night.  42
