.DISCUSSION...
Issued at 1207 PM CDT Wed Sep 17 2025

An unsettled weather pattern continues across Deep South Texas. 
Daytime heating in combination with abundant tropical moisture 
and a series of disturbances passing overhead will keep rain and 
thunderstorm chances in the forecast through mid-week. The rain
chances will typically remain highest (30-60%) along and east of 
US 281/I-69C. Much of this activity will be along the seabreeze, 
with peak timing for precipitation in the early afternoon into the
early evening. 

Increased cloud cover and rain chances, primarily during peak 
afternoon heating, will keep temperatures near normal through mid-
week. 
  
Onshore flow and slightly elevated seas will maintain a moderate 
risk of rip currents along the beaches of the lower Texas coast 
through Thursday.

Scattered showers moving through the area this evening may 
briefly move across an airfield, however conditions are expected 
to predominantly remain VFR. Convection will likely decrease 
overnight, with another round of convection possible Thursday 
morning through the afternoon. Conditions may briefly drop to 
MVFR or IFR levels if any shower or thunderstorm moves over an 
airfield.

Generally favorable conditions with mostly light to moderate winds 
and seas of 2 to 4 feet. Rain and thunderstorm chances through the
week will continue on the waters off the lower Texas coast. Any 
shower or thunderstorm activity will lead to localized increased 
winds and seas.
