Area Forecast Discussion . UPDATED National Weather Service Brownsville TX 748 PM CST Tue Dec 10 2019

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. MVFR conditions prevail across the RGV as CAA persists over the region. The 00Z BRO sounding shows a pretty deep saturated extending from just off of the surface extending up to the 750 mb level. Expect MVFR ceilings to persist tonight due to the relatively deep moisture layer in place. The moisture layer may erode away some on Wednesday due to increasing low level mixing but expect VFR conditions to be slow to return for BRO and HRL. Conditions at MFE will likely improve a little more quickly as drier air filters in from the west. The PGF will relax gradually throughout the next 24 hours allowing for the northerly surface flow to abate.

PREV DISCUSSION. /issued 245 PM CST Tue Dec 10 2019/

SHORT TERM (Now through Wednesday night): Temperatures have fallen into the 50s across the CWA this afternoon as the cold Canadian airmass across the north-central United States continues to move southward into Texas in the wake of the cold front that moved through the Rio Grande Valley earlier today. Winds continue to gust between 25 to 30 mph from the north this afternoon with a few gusts between 35 to 40 mph along the lower Texas coast. Winds will begin to diminish from west to east this evening as the cooler air continues to filter into deep South Texas tonight. Will continue wind advisories for the coastal counties through this evening. Surface observations and radar images continue to indicate light rain/drizzle across the southern and eastern portions of the CWA this afternoon. Will continue to mention at least a slight chance of rain across the coastal sections tonight but rain chances will diminish late tonight into Wednesday as drier air filters into the RGV Wednesday as a 500mb shortwave trough moves across the area Wed morning. Temperatures will be below normal tonight through Wed night but will remain above freezing tonight and Wed night.

LONG TERM (Thursday through Tuesday): A mid level trough will move over Texas and the central Plains Thursday into Friday as northwest flow aloft continues over the region through Saturday. The mid level flow then becomes southwest on Sunday as another 500mb trough digs into the Great Basin and into the Four Corners Region early next week. Temperatures will steadily warm through the rest of the week into the weekend. Generally rain-free conditions are expected Thursday through Sunday as north to northeast flow across the CWA. A slight chance of rain will be possible on Monday as moisture increases ahead of the next cold front. Next cold front is expected to arrive late Monday into early Tuesday.

MARINE (Tonight through Wednesday night): Seas were near 9 feet with north winds near 27 knots with gusts to near 33 knots at buoy020 early this afternoon. Winds were gusting to near 36 knots at the South Padre Island Coast Guard Station NOS gage as well. Very strong north winds will prevail across the coastal waters this evening as surface high pressure continues to build across the lower Texas coast tonight in the wake of the cold front that moved offshore earlier today. Will continue Gale Warning for the Laguna Madre through midnight and for the offshore waters through late tonight but winds should begin to diminish below Gale Warning criteria across the lower Texas coast this evening and offshore tonight. Small craft advisories will need to replace the Gale Warnings for the bay waters this evening and offshore tonight. Winds and seas will gradually diminish late tonight into Wednesday as the pressure gradient begins to weaken across the western Gulf of Mexico. Light to moderate north winds will prevail across the lower Texas coast Wednesday with stronger winds offshore. Small craft advisories will likely still be needed for the offshore waters Wednesday before seas begin to diminish during the afternoon. Light northeast winds should prevail across the coastal waters Wed night as the pressure gradient continues to weaken across the lower Texas coast.

Thursday through Saturday . Marine conditions will continue to improve on Thursday as high pressure settles across the area. Light winds and low to moderate seas are expected to Thursday into Friday. Elevated seas may support exercise caution conditions Thursday and Thursday night. Otherwise, favorable marine conditions should prevail Friday into the first half of the weekend.

BRO WATCHES/WARNINGS/ADVISORIES. TX . Wind Advisory until midnight CST tonight for TXZ256-257-351.

GM . Gale Warning until midnight CST tonight for GMZ130-132-135.

Gale Warning until 3 AM CST Wednesday for GMZ150-155-170-175.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
