New AVIATION

SHORT TERM
(Today through Friday)
Issued at 202 AM CST Thu Dec 7 2023

Clouds will continue to increase today as an upper level disturbance approaches the area. Guidance generally keeps any mention of showers out of the forecast but with PWATs increasing to around 1.4" through this afternoon, there is a small chance that we could see at least some light showers as the upper level disturbance crosses the area from the southwest to northeast tonight. With that in mind, there are some silent PoPs in the forecast for tonight.

As onshore flow persists, more moisture will stream into the area today leading to increased cloud cover and warmer temperatures.
Today's highs will be in the mid to upper 70s, with lows in the 60s overnight. Highs for Friday will be in the 80s.

Onshore winds will increase on Friday ahead of an approaching cold front. Small Craft Advisory conditions are possible over the offshore waters Friday, but confidence is low.

LONG TERM
(Friday night through next Wednesday)
Issued at 202 AM CST Thu Dec 7 2023

Key Messages:

- Strong cold front Saturday evening brings a medium chance for sustained winds around 30 mph over the Coastal Bend overnight

- Low chance (20-30$) of showers and thunderstorms Saturday evening along the front, then again the middle of next week

- Medium chance (30-60%) for freezing temperatures early Monday morning for low-lying drainage areas from McMullen to Refugio County

Saturday's highs will be about 10 degrees above normal, ranging from the upper 70s to mid 80s. These temperatures will get absolutely obliterated as a strong cold front pushes through Saturday evening (trended later), bringing colder and much drier air in its wake.
Northerly winds will be strong in wake with gale force conditions over the waters and near Wind Advisory criteria (sustained 30 mph)
over the Coastal Bend overnight into early Sunday morning. Included a low 20-30% chance of showers and even lower chances of thunderstorms during a 6-hr window with FROPA from 6PM Saturday to midnight. It'll be very quick with greatest chances and coverage over the waters. Highs on Sunday drop to the low to mid 60s on Sunday.

Although weak onshore flow returns Sunday night, there's going to be a delay in dewpoints and moisture recovering. Sunday night will be the coldest night across South Texas with clear skies, light winds, and dewpoints in the 20s inland causing efficient radiational cooling. Currently have mid 30s over the inland Coastal Plains and Brush Country, to the mid 40s along the coast. However, low-lying drainage areas could see freezing temperatures. In fact, NBM shows a medium chance (30-60%) of freezing minimum temperatures from McMullen to Refugio County.

Rain-free conditions continue through Tuesday with PWAT values below normal and temperatures warmer with highs on Tuesday in the low 70s and lows Tuesday night generally in the 50s. Low to medium (20-40%)
rain chances return at the end of the long term, during the middle of next week as PWAT values climb to near 1.50" in association with Pacific moisture of a mid-level low or trough traversing from the Pacific across Mexico into South Texas.

AVIATION
(12Z TAFS)
Issued at 447 AM CST Thu Dec 7 2023

While a few sites across the Coastal PLains and Brush Country will experience some MVFR ceilings and/or visibility this morning, VFR conditions are expected to prevail after 14Z. Generally southerly winds will increase around 18Z with winds gusting to around 20 knots. Cloud cover will increase late in the TAF period, which could lead to some MVFR/IFR ceilings after 07Z.

MARINE
