Area Forecast Discussion . UPDATED National Weather Service Brownsville TX 551 AM CST Sat Dec 14 2019

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. Pockets of patchy fog have impacted the aerodrome sites, especially at BRO and HRL, during the overnight with visibilities generally averaging at MVFR levels but have occasionally bounced into the IFR and VFR range at times. Any lingering patchy fog is to dissipate by mid-morning and will yield to VFR conditions with sunny skies and light to moderate south-southwesterly winds by the afternoon. Expect southerly winds to remain rather breezy Saturday night but some minor reductions regarding visibility or ceilings could be possible during the overnight hours, especially at MFE where winds will remain the lightest.

PREV DISCUSSION. /issued 243 AM CST Sat Dec 14 2019/

Short Term (Now Through Sunday): Pockets of shallow patchy fog will be possible into this morning, otherwise expect for clear skies with early morning lows mainly in the 50s with a few locales down into the 40s. Otherwise, the main story for today will be the very warm temperatures, which are currently forecast to break the daily maximum temperature records at the climate sites (Current records: BRO (84), HRL (87), MFE (89)). In addition to the sunny conditions today, the temperatures spike due to the effects of compressional heating with gradually increasing winds from out of the south- southwest. Winds become more south-southeasterly tonight and this will help advect low-level gulf moisture further inland. This should result in a milder and more muggy night across the region for Saturday night into Sunday. We'll monitor for fog development as well. Sunday will remain very warm but will also feature breezy to windy conditions as the pressure gradient intensifies between surface high pressure to the east and a broad region of low pressure extending from north Texas into the terrain of Mexico. The southerly winds will be maximized across the lower valley and along the coast. A Wind Advisory may be necessary on Sunday across these areas.

LONG TERM (Sunday Night through Friday): Southwesterly flow aloft continues Sunday night into Monday as low pressure deepens across the Southern Plains, eventually sending a strong cold front through Deep South Texas on Monday. The NAM has bumped timing up on the front slightly, with strong northerly winds arriving by early Monday afternoon. Temperatures barely get into the 80s before the northerly shift, with a nearly 40 degree drop expected by Tuesday morning. Moisture has remained limited with this system, something the ECMWF has been consistent with over the past few runs. The GFS has begun to shift toward the drier solution, so have kept POPs generally less than 20 percent near the coast.

Weak mid level ridge of high pressure and much drier air work into the region Tuesday into Thursday. Northerly winds remain persistent and temperatures mid week stay below normal into the 60s. The next low pressure system dives off the Rockies into the Plains Thursday into Friday, bringing southerly winds and low level moisture back across the lower Texas coast before a weaker front arrives Friday afternoon. The next chance of rain may arrive with this moisture in the way of streamer showers Thursday night into Friday morning, and during the brief window along the frontal passage before high pressure and drier air gain control. Beyond the long term, the weekend before Christmas looks near normal and dry.

MARINE (Now through Sunday): Favorable marine conditions with light winds and low seas continue through this morning before southerly winds begin to gradually increase from this afternoon into tonight. Cautionary wording will like be needed overnight due to the uptick in winds and for seas increasing to moderate levels. Winds become breezy for Sunday with increasing seas to hazardous levels. A Small Craft Advisory will likely be needed across all of the lower Texas coastal waters on Sunday.

Sunday Night through Friday: Hazardous seas continue into the long term period with moderate to strong southerly flow Sunday night becoming strong northerly flow Monday afternoon with the passage of a strong cold front. Northerly winds gradually diminish into Wednesday, allowing seas to slowly subside. Southerly flow returns Thursday as low pressure deepens across the Plains and high pressure works offshore. A weak cold front arrives on Friday, bringing northerly flow back across the coastal waters to start next weekend. At this time, winds Thursday and Friday look to remain relatively light and should allow seas to continue to diminish into next weekend. Conditions may remain hazardous for small craft into Thursday, especially across offshore Gulf of Mexico waters beyond 20 nautical miles.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
