Long Term
(Wednesday through next Sunday) Issued at 235pm CST Monday Nov 28 2022

Key Messages:

- Gale Watch in effect for Wednesday from 10am - 9 PM

- Next cold front arrives Wednesday morning

- Wind Advisory conditions possible along the immediate coast Wednesday

- Minor coastal flooding possible Thursday and Friday

- Patchy fog possible later in the week

The next cold front is set to arrive Wednesday morning and will push offshore by Wednesday afternoon. Much cooler temperatures and breezy winds will develop behind the cold front Wednesday into Wednesday night. A Gale Watch is in effect for the bays and Gulf Waters Wednesday into Wednesday night. Winds may approach advisory levels over the Barrier Islands. With dry air filtering in immediately behind the front, isolated showers will be focused along the coast and Gulf Waters during the morning hours on Wednesday. Temperatures will be in the 60s across South Texas. Lows will drop into the 40s and 50s Wednesday night into Thursday morning.

Winds will decrease Wednesday night. Precipitation chances return again for Thursday for areas towards the coast as PWATs (Precipitable Waters) increase to around 1.5" along the coast in response to a developing coastal trough. Rain chances will be further aided by isentropic ascent at the 295K level and embedded shortwaves that will track east across the northern periphery of an upper level high pressure. Expect precipitation mode to be primarily showers as atmospheric dynamics do not appear to be conducive enough to support thunderstorm development.

While P-ETSS is keeping tide levels below criteria for minor coastal flooding (>1.8ft MSL), persistent moderate northeasterly and easterly winds have led to an increased risk for minor coastal flooding in the past, so will continue to mention the possibility for that to occur during high tide on Thursday.

Rain chances are forecast to continue through the weekend for areas closer to the coast as PWAT (Precipitable Water) values remain near 1.5" and a series of embedded shortwaves continue to track around the northern periphery of a high centered over the NW Gulf of Mexico.

Will keep the mention of sea fog as winds become east to southeast later this week and bring higher dewpoints across the Gulf Waters. Have kept a mention of sea fog out of the forecast grids for now; but will continue to monitor over the next couple of days.

Temperatures will warm into the 70s and 80s Friday into the weekend with lows in the 60s to low 70s.

Marine
Issued at 235pm CST Monday Nov 28 2022

Winds will become light to moderate and shift to a more southeast and southerly flow tonight, with Small Craft Exercise Caution conditions expected across the coastal waters. Isolated showers and even a rumble of thunder will be possible tonight and Tuesday as a warm front moves north into the area. Another round of sea fog will be possible tonight as warm air moves across the cooler waters. The potential for sea fog will continue Tuesday night through Wednesday morning ahead of the next cold front.

The cold front is expected to move through the area Wednesday morning with strong to very strong northerly winds developing in its wake. Gale conditions will be possible in the wake of the front through Wednesday evening. A Gale Watch is in effect for the bays and Gulf Waters Wednesday into Wednesday night. Winds will become northeast to east and decrease to moderate levels by Thursday afternoon. Isolated to scattered showers and a few thunderstorms will be possible Tuesday night through Wednesday.
