Synopsis for the middle texas coastal waters -
weak to moderate southerly flow tonight will increase to 20-30 knots tomorrow afternoon through Wednesday night, which lead to the issuance of a small craft advisory. Wave heights of 2-3 feet tonight will build to 7-10 tomorrow afternoon through tomorrow night when winds are expected to increase. Wind becoming weak to moderate south to southeast Thursday. A cold front will move across the waters Thursday night and result in moderate to strong offshore flow through Friday. Significant precipitation is not expected along the front. As surface high pressure enters then moves eastward across the gulf of mexico, and as surface low pressure deepens across the southern plains, expect wind to become weak northeast Friday night then weak southeast by Saturday night, followed by weak to moderate onshore flow Sunday.

New SHORT TERM, LONG TERM, MARINE

SHORT TERM
(Tonight through Wednesday night)
Issued at 258 PM CST Tue Feb 20 2024

High pressure will dominate the short term as an upper-level ridge moves across the region. With light winds and a moist surface layer, there is a medium to high chance for patchy to locally dense fog tonight with a low chance of patchy fog tomorrow night ahead of our next cold front. The best chance for dense fog tonight will be from the Victoria Crossroads south towards the Coastal Plains and eastern Brush Country where the models are showing condensation pressure deficits less than 10mb and low dewpoint depressions. The limiting factor to the development of dense fog are the winds. Models are showing winds a touch too high for efficient fog development tonight.
If winds are lighter than forecast, the probability of fog will increase. Winds tomorrow night are expected to be over 12 knots which will once again be the limiting factor. Under the influence of the ridge and onshore flow, unseasonably warm temperatures are expected throughout the short term.

LONG TERM
(Thursday through next Monday)
Issued at 258 PM CST Tue Feb 20 2024

In response to disturbances predicted to move across the Plains, a cold front is expected to move across the CWA Thursday. Despite above normal PWAT values expected, likely due to moisture convergence along the front, no significant precipitation is expected along the front when considering the expected thermodynamic profile. Patchy fog may develop along the front since the foregoing profile is expected to be conducive to radiation fog (with high clouds as the caveat). The combination of low relative humidity and wind may result in Elevated fire weather conditions Thursday afternoon (with wind as the limiting factor.) Dry Friday/Saturday. A quasi-zonal upper pattern Sunday/Monday will contribute to onshore flow/increasing moisture, yet no significant precipitation expected owing to the predicted thermodynamic profile (GFS deterministic.)



AVIATION
(18Z TAFS)
Issued at 1149 AM CST Tue Feb 20 2024

VFR conditions are expected to continue through this afternoon and into this evening. As we head into tonight, after 06z, the probability of fog will increase beginning at VCT and spreading southward to ALI and CRP throughout the night. Models are showing a medium to high chance of LIFR/IFR conditions across most sites late tonight into tomorrow morning, however, due to low confidence on timing, only went with a tempo for now. There is currently a low chance that the fog could extended westward into COT and LRD.
Apart from fog, there is also a low to medium chance for low ceilings across the region. Any fog or lower ceilings should dissipate/move out tomorrow morning after 14/15z as winds begin to increase.

MARINE
Issued at 258 PM CST Tue Feb 20 2024

Weak to moderate southerly flow tonight will increase to 20-30 knots tomorrow afternoon through Wednesday night, which lead to the issuance of a Small Craft Advisory. Wave heights of 2-3 feet tonight will build to 7-10 tomorrow afternoon through tomorrow night when winds are expected to increase. Moderate to strong offshore flow expected Thursday in response to a cold front. Significant precipitation is not expected along the front. As surface high pressure enters then moves eastward across the Gulf of Mexico, and as surface low pressure deepens across the Southern Plains, expect wind to become weak northeast Friday night then weak southeast by Saturday night, followed by weak to moderate onshore flow Sunday and Monday. Moderate to strong onshore flow anticipated Tuesday, in response to an an approaching upper level disturbance (GFS/ECMWF deterministic).
