Synopsis:  Tuesday night fog could linger into Wednesday morning and start up again on Wednesday night. The winds off the surface as well as at the 2,500 feet (925 mb) level at 25 mph will subside around 4 am (from south to north) allowing an opportunity for fog to develop (mainly inland).  As dewpoints stay in the lower 50’s while water temperatures stay in the 60’s then that will slow down  (sea) fog development except for some locations.  Water temperatures are mostly in the 60’s (shallower water in the 50’s) while dewpoint temperatures stay in the low 50’s (stifling fog).

Air flow out of the southwest will not be conducive for fog development with warmer temperatures compared the mid 30’s on Tuesday morning as the warm pushes up the dewpoint temperature.

High pressure building into the 5,000 feet (850 mb at 56-62 degrees Fahrenheit) level will help warm temperatures into the 70’s and 80’s on Wednesday.  Patchy fog on Wednesday night could be on the lighter side as dewpoint and ambient temperatures stay more than 3 degrees apart for inland locations.  The fairly low dewpoints and airflow out of the southwest should keep Sea Fog (warm moist air moving over cooler waters) out of the picture as well.

In the long term for the extended period, days 3 to 7, Thursday through Tuesday, another cold front will move through South Texas on Thursday afternoon with a trough pushing through earlier on Thursday that will shift winds out of the south to out of the northwest.

Temperature highs on Thursday will be in the 70’s but cooler and drier air will move in behind the front dropping overnight low temperatures into the 40’s along the coast (coast to Rio Grande Plains) and into the upper 30’s further inland (Cotulla to Victoria).

This front will stall out over the coast on Friday, and then will turn pick up moisture over the Gulf, heading back north into the Texas coast on Saturday.  The return of the front with increased moisture (1.5″) will result in showers over the coast and open water during the south to north retreat.

The further north the front moves then the more the rain chances will come to an end on Saturday night.   Then, another cold front will push south in the area Sunday afternoon and evening.  Showers will develop along the front (as well as out in front of the boundary), but the showers will taper off through Monday morning.  Early next week, cooler, drier air will move back down into South Texas.
