.DISCUSSION...
Issued at 1145 PM CDT Sun Oct 25 2026

Benign conditions are expected tonight with light variable winds 
and mostly cloudy skies. The lows will be a few degrees warmer 
tonight, ranging in the mid 50s over the Piney Woods region, the 
upper 50s to mid 60s for the rest of the inland portions, and the 
lower 70s along the coast. We could once again see isolated areas 
with patchy fog developing during the early morning hours, and 
should burn off quickly around sunrise. 

Models have backed off a little with tomorrow's rain chances, and
now places the higher rain chances over Matagorda Bays adjacent 
waters. This coincides with my thinking yesterday, where I 
mentioned that I think we could still be influenced by the mid to 
upper level ridge positioned over Louisiana...enough to keep rain 
chances over most of Southeast Texas fairly low. The forecast now 
has less than 10% chance of rain for Monday for the majority of
the CWA, accompanied by partly cloudy skies and east winds at 5 
to 10 mph. Infrequent gusts of 15 to 20 mph will be possible 
closer to the coasts. The highs will generally be in the lower 
80s, with isolated spots possibly reaching the mid 80s. Moisture 
from the Western Gulf will move in from the Matagorda Bay region 
Monday night, keeping skies mostly cloudy overnight. This will 
also bring in warmer nighttime temperatures, with lows ranging in 
the upper 50s over the Piney Woods region and the lower to upper 
60s for the rest of the inland portions. 

As an upper level trough moves across the Southern Plains Tuesday 
morning, the mid level ridge will continue to progress further east, 
into Southeast CONUS. Having less of the ridge influence and a 
little more moisture to work with, rain chances will increase, 
mainly for areas west of I-45. Under a southeast flow, PWATs will 
continue to rise Tuesday night into Wednesday, ranging between 1.3-
1.8 inches and lead to slightly higher chances of showers and 
thunderstorms. East winds will briefly return on Thursday along 
with drier air, thus, we are not expecting as much rain activity 
that day. Advancing into Friday and Saturday, models point out 
another healthy surge of moisture moving through the region as a 
coastal trough potentially develops along the Texas coast.

.AVIATION...
(06Z TAF Issuance)
Issued at 1145 PM CDT Sun Oct 25 2026

High clouds should limit fog development overnight. Cannot 
completely rule out some patches early Monday morning at fog-prone
sites likes KCXO, though any FL impacts should be brief and 
limited. Breeze E/SE winds develop once again Monday morning, 
becoming light in the evening. VFR conditions dominate throughout 
the TAF period.

.MARINE...
Issued at 1145 PM CDT Sun Oct 25 2026

Caution Flags remain in effect through Monday night for moderate 
east winds and Seas of 4-6 feet, possibly reaching 7 feet 
offshore. There is also a moderate to high risk for strong rip 
currents along the Gulf facing beaches. Winds relax a bit and seas
subside a foot or two Tuesday into Wednesday. Light to 
occasionally moderate east winds and seas between 3-5 feet will 
continue through the rest of the week. 

Rain chances are expected to return this week as the ridge shifts
east and surface moisture converges over the Western Gulf waters.
Expect isolated to scattered showers and thunderstorms most days.
Locally higher winds and seas could occur in and near strong 
storms.
