Synopsis..
light to moderate onshore flow will persist tonight across the coastal waters as low pressure develops and tracks eastward across the plains. A strong cold front is expected to move across the coastal waters late Saturday evening, bringing a chance of showers or Thunderstorms along the front. Strong northerly winds behind the front will likely produce gale conditions for most of the waters through Sunday morning. Building seas of 10 feet and higher will occur in the wake of this front. Winds will slowly diminish and seas will slowly subside by Sunday evening as the center of the high pressure area quickly shifts into the northwest gulf. Onshore flow will redevelop on Monday as high pressure shifts eastward along with low pressure developing across the southern plains.

New AVIATION

SHORT TERM
(Today through Sunday)
Issued at 342 AM CST Sat Dec 9 2023

The main weather headline in the short term period is the arrival of a strong cold front, which will bring cooler temperatures, low rain chances, breezy north winds, and some adverse marine and beach conditions.

A warm start to the weekend is in store for all of Deep South Texas, with cloud cover and patchy fog clearing by mid to late morning.
Plentiful sunshine and persistent low level southerly flow ahead of a cold front will result in highs warming into the low to mid 80s this afternoon. The cold front is expected to arrive late Saturday evening across Deep South Texas, with most of the region remaining rain-free. The exception will be across Cameron and Willacy counties, where there may be sufficient moisture and forcing along the front to yield isolated to scattered showers and thunderstorms.
The latest high res guidance continues to highlight at least isolated convection along the front late Saturday evening across the Lower Rio Grande Valley, with higher coverage over the Gulf waters.
Temperatures will quickly fall with the arrival of the cooler airmass, with lows expected to range from the mid 40s along the Northern Ranchlands to low 50s across the Rio Grande Valley.

Breezy north winds in wake of the cold front will bring adverse marine and beach conditions along the Lower Texas Coast, in addition to coastal Cameron, Willacy, and Kenedy counties tonight into Sunday morning. Confidence has remained high (80% or greater) on the potential for gale force gusts over the Laguna Madre and Gulf waters, with medium to high confidence (60-80%) on the potential for wind gusts exceeding wind advisory criteria over the coastal counties. For now, opted to issue a Gale Warning for the Laguna Madre and Gulf waters for tonight into Sunday morning, and a Wind Advisory for the Lower Texas beaches and coastal Cameron, Willacy, and Kenedy counties. The Wind Advisory may need to be extended further inland to include the rest of the coastal counties if confidence increases on reaching Wind Advisory criteria. In addition, Small Craft Advisory conditions will likely continue through Sunday evening over the Gulf waters. Building seas will result in a high risk of rip currents and high surf advisory tonight into Sunday.

Otherwise, Sunday will feature noticeably cooler temperatures with highs in the low to mid 60s region wide. It will still be a bit breezy with northerly winds around 15-20MPH through most of the day, but should decrease slightly by late Sunday afternoon as the pressure gradient slackens.

LONG TERM
(Sunday night through Friday)
Issued at 342 AM CST Sat Dec 9 2023

A weak 500mb ridge of high pressure with very dry air aloft builds into the region Sunday night into Monday, as the surface high pressure slides eastward across the Southeast. A coastal trough with some mid-level support and ample moisture sets up along the lower Texas coast Tuesday through late week. Rain chances increase mid to late week with the next system, especially Wednesday into Friday.

The coldest night of the week will be Sunday night due to efficient radiational cooling. Monday morning lows into the mid to upper 30s across the ranchlands and upper 30s to low 40s across the RGV. Wind Chill values may briefly dip below freezing across the northern ranchlands Monday morning, with winds below 10 mph. Abundant sunshine and the return of southeasterly winds will allow highs to reach the upper 60s to near 70 on Monday. Overall, expect near normal highs Tuesday through Thursday with lows warming into the low 60s by the end of the week. Finally, some hazardous beach conditions may linger into Monday morning.

AVIATION
(12Z TAFS)
Issued at 535 AM CST Sat Dec 9 2023

Widespread MVFR/LIFR ceilings are observed across the region this morning as persistent low level southerly flow transports rich moisture. Ceilings are expected to improve to VFR by mid to late morning, with VFR prevailing through the remainder of the period.
A cold front will arrive late this evening across the terminals, with a low potential for isolated to scattered convection along the boundary. Confidence was too low to warrant a mention in the TAF at this time, but will continue to be monitored. Otherwise, expect breezy northerly winds with gusts up to 25 knots possible.

MARINE
Issued at 342 AM CST Sat Dec 9 2023

Today through Sunday...The pressure gradient will weaken slightly today, which will result in generally favorable marine conditions. A cold front will approach the region late this evening from the northwest, with isolated to scattered showers and thunderstorms expected along the boundary. In wake of the frontal passage, expect building seas and gale force gusts across all of the Gulf waters and Laguna Madre tonight through Sunday morning.
Although conditions will improve by late Sunday morning or early Sunday afternoon, adverse marine conditions will likely continue with breezy winds and high seas. A Small Craft Advisory will likely needed through Sunday evening.

Sunday Night through Thursday...Small Craft Advisories will continue into Sunday night. Southeasterly winds return Monday as high pressure moves eastward across the northern Gulf, resulting in marine conditions improving fairly quickly, potentially becoming generally favorable by early Monday afternoon. Coastal low pressure brings a chance of rain to the coastal waters mid to late week and gradually builds seas into Thursday with Small Craft Advisories likely returning late Wednesday.
