Area Forecast Discussion
...UPDATED National Weather Service Corpus Christi TX
1148am CST Thu Nov 14 2019

Satellite imagery shows the upper low over the Middle Texas coast near Rockport moving to the east-northeast. The coastal trough/low pressure area appears to have moved east of the offshore waters. Band of heaviest showers is in the process of moving out of the offshore waters. As the upper low exits the region, there will be wraparound moisture that will affect the coastal plains. Scattered showers along with areas of light drizzle will continue through most of the afternoon while drier conditions are expected for the Brush Country. North winds will continue to gradually increase as the gradient increases between the low pressure area over the northwest Gulf of Mexico and high pressure building into south Texas. Lowered high temperatures down a little bit, closer to the Consshort output.

MARINE...North winds will continue to increase through the afternoon as the gradient strengthens between to the low east of the offshore waters and high pressure building into south Texas. The SCA (Small Craft Advisory) will continue as is for the Gulf waters while SCEC conditions (Small Craft Should Exercise Caution) will exist over the bays. Inserted a mention of fog near the bays through the afternoon.

AVIATION... Not going to see much improvement today with IFR to MVFR (Marginal Visual Flight Rules) ceilings at all terminals. Scattered showers will continue this morning at CRP and ALI then linger at VCT through the afternoon. By tonight expect all sites to return to MVFR.
