Area Forecast Discussion . UPDATED National Weather Service Brownsville TX 532 AM CST Sat Nov 28 2020

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. Unsettled weather conditions with veering winds will occur during the TAF period as a cold front moves from west to east across Deep South Texas and the Rio Grande Valley.

PREV DISCUSSION. /issued 335 AM CST Sat Nov 28 2020/

SHORT TERM (Now through Sunday): A cold front is expected to pass from west to east through Deep South Texas and the Rio Grande Valley. The best chance for showers and thunderstorms will occur today and tonight in association with the passage of the front, with the precipitation confined to the lower Texas coastal waters on Sunday as the front pushes farther offshore. While above normal temperatures are still anticipated today, cooler temperatures will occur tonight and tomorrow in the wake of the front.

LONG TERM (Sunday Night through Friday): The latest GFS/ECMWF remains in good agreement with persistent west to northwest flow aloft and northerly flow at the surface through Tuesday. This will allow much drier air to filter into deep south Texas Sunday night through Monday night as cold air advection continues. Low temperatures Monday morning are expected to fall into the 40s at most locations. A reinforcing surge of surface high pressure arrives on Monday resulting in another push of cooler air and moderate to breezy north winds. The 1028mb surface high pressure builds across Texas on Monday into Monday night before moving east across the northern Gulf coast on Tuesday. High temperatures on Monday will be in the low to mid 60s with breezy north winds. Light winds and mostly clear skies will allow temperatures to drop into the low to mid 30s across the northern ranchlands to the upper 30s to the lower 40s across the lower Rio Grande Valley Tuesday morning. There is some potential for portions of Kenedy, Brooks, and Jim Hogg counties to fall to or below the freezing early Tuesday morning.

Temperatures gradually warm Tuesday and Tuesday night as southeast flow develops. Highs on Tuesday are expected to reach the mid to upper 60s to around 70. A slight chance of rain returns Wednesday as a surface trough develops along the lower Texas coast. Models begin to diverge by midweek with the timing of the next front and the rain chances. Will continue to mention rain chances for Wednesday night through Thursday night with the next cold front but will lean on the drier side of the guidance for now. Temperatures are expected to remain below normal Thursday and Friday in the wake of the front.

MARINE (Now through Sunday): Increasing winds and building seas are expected during this period of the forecast as a cold front gradually transitions through the Lower Texas Coast. While favorable marine conditions are forecast for today, Small Craft Exercise Caution and Small Craft Advisory are likely to be needed tonight through Sunday due to strong winds and rough seas.

Sunday Night through Thursday: Ongoing Small Craft Advisories will likely continue into Monday night due to strong north winds and high seas. Conditions briefly improve Tuesday into Tuesday night as high pressure settles across the western Gulf. Another cold front is expected to move into the coastal waters around midweek. Adverse conditions will develop along the lower Texas coast Wednesday night through Friday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
