New AVIATION

SHORT TERM
(Today through Wednesday)
Issued at 205 AM CST Tue Dec 5 2023

Weak east to northeasterly winds will continue today through Wednesday as a weak reinforcing surge of high pressure and drier air pushes through tonight into Wednesday morning. Right entrance divergence region of the jet and 500mb bands of positive vorticity will continue to contribute greater cloud coverage over the southern half of the CWA and the coast through this evening. Late tonight through Wednesday, the jet moves off to the east as low-level high pressure (925-700mb) centers over South Texas; this will cause subsidence and mostly sunny skies on Wednesday. Moisture remains below normal today with PWAT values less than 1.0" and even drier on Wednesday with PWAT values below 0.5" (<25th percentile). Therefore, there are no rain chances through Wednesday.

Although skies will be clearing, drier air will push through tonight and make it difficult for fog development. In fact, NBM and SREF probabilities of less than 3 miles is less than 20%. Highs today and Wednesday will range in the low to mid 70s with lows tonight dropping down into the mid 40s inland to the mid 50s along the Rio Grande and coast.

LONG TERM
(Wednesday night through next Monday)
Issued at 205 AM CST Tue Dec 5 2023

Key Messages:

- Warm late this week, then cooler this weekend behind a cold front.

- Slight chance of rain along the coast and Victoria Crossroads Saturday. Better chances for rain over the waters for the weekend.

Moisture will gradually begin to return to South Texas Wednesday night and Thursday as onshore flow returns. PWATs will increase to 1.3-1.5 inches ahead of a cold front expected to reach the area Saturday. Models have come into the better agreement with regards to the timing, trending closer to an 18Z-00Z frontal passage. A slight chance of showers will be possible Saturday through early Sunday as the front surges south, mainly over the Victoria Crossroads and along the coast. A better chance for showers and, perhaps, isolated thunderstorms remains over the waters. While strong northerly winds are still expected, models have backed off on the winds over land so have followed the NBM's lead and reduced them slightly. Forecast winds continue to be strong to very strong over the waters and across the immediate coast behind the front, with Small Craft Advisory conditions expected and a high chance of frequent gusts to Gale Force through early Sunday.

Warm temperatures will continue through late this week before the cold front Saturday/Saturday night brings cooler and drier air back into South Texas. Highs will fall from the 70s and 80s into the 60s behind the front. Overnight lows will dip into the 40s Saturday and Sunday nights.

Behind the front, low relative humidity values will combine with 10 to 15 mph winds, leading to Elevated Fire Weather conditions Saturday afternoon over the western Brush Country. Winds will weaken Saturday night, ending the potential for Elevated Fire Weather conditions.
