Area Forecast Discussion
...UPDATED National Weather Service Corpus Christi TX
1144am CST Wednesday Jan 22 2020

Widespread showers continue to move across the northern Coastal Bend into the Victoria Crossroads region in strong warm air advection zone ahead of the short wave trough moving into the Texas Big Bend. Bumped up Probability of Precipitation to 100 percent for this area for rest of today. Conditions will be improving from west to east by the afternoon as the short wave trough moves through the area and the warm air advection shifts to the east. Kept the mention of slight chance for thunderstorms this afternoon for the coastal plains as models depict MUCAPE values close to 500 j/kg. Adjusted Probability of Precipitation to show a quicker decrease during the overnight hours with no mention of rain in the forecast for coastal areas for Thursday morning. Also put in mention of fog for inland coastal plains into the eastern Brush Country for tonight. With decreasing clouds, light winds, and high boundary layer moisture, fog looks likely for late tonight into Thursday morning.

Tide levels are running about 1.5 feet above expected along the coast this morning. This should lead to minor coastal flooding at the time of the next high tide late this afternoon. Made no changes to the current Coastal Flood Advisory.

MARINE...Strong onshore flow will persist over the Gulf waters for the rest of today with a gradual decrease this evening. Seas will remain elevated through the evening hours. Kept SCA (Small Craft Advisory) going as currently configured. Showers will continue to spread into the waters today with isolated to possibly scattered thunderstorms forming late this afternoon and evening.
