Area Forecast Discussion . UPDATED National Weather Service Brownsville TX 515 PM CST Wed Feb 24 2021

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. Current satellite and surface observations are showing VFR conditions over all aerodromes. Later this evening MVFR conditions are expected to develop before IFR ceilings develop overnight. IFR is expected much of the overnight, especially across HRL and BRO, before lifting to MVFR mid morning. BRO will stay in MVFR conditions with low clouds on Thursday while HRL and MFE should return to VFR by midday. Gust winds are beginning to diminish across the area remaining moderate overnight. Thursday afternoon winds will increase again with gusts to 30 kts.

PREV DISCUSSION. /issued 247 PM CST Wed Feb 24 2021/

SHORT TERM (Now through Thursday Night): A pretty stagnant and stable weather pattern is expected in the short-term period. Subtropical ridging over the Caribbean Sea will keep abnormally warm temperatures in place through Thursday night. The biggest two stories will be the breezy surface winds during the daytime on Thursday and the dense fog expected along the coast. A strong pressure gradient will remain in place as low pressure across northeast Mexico interacts will strong high pressure over the eastern Gulf of Mexico. Similar to today, south to southeast winds will increase mid-late morning Thursday, peaking by early afternoon. Although winds will be breezy for the majority of the CWA, strongest winds will occur across Cameron and Willacy Counties, where gusts will rival today's gusts -- around 30 to 35 mph. A slow and nearly stationary, weak cold front will continue to push south from central Texas through the day on Thursday, stalling just north of the CWA by Thursday evening. Though chances are very slight, enough low level convergence may produce a few showers across the northern Ranchlands Thursday night into Friday morning. Expect very warm temperatures over the next couple of days, with lows in the mid-upper 60s tonight and daytime highs in the mid-upper 80s on Thursday afternoon. Lows will be a tad lower, especially for the Northern Ranchlands, on Thursday night as the weak cold front tries to ooze its way south.

A Marine Dense Fog Advisory has been issued for the nearshore Gulf waters through 9 AM Thursday morning. There might be periods where the fog lifts or dissipates this afternoon, but ingredients will remain in place for more fog development this evening and overnight tonight, especially over the nearshore Gulf waters. Patchy dense fog may advect over SPI and the Laguna Madre later on this evening or tonight. A Dense Fog Advisory may be needed for coastal zones of Cameron, Willacy, and Kenedy Counties.

LONG TERM (Friday through Wednesday): A weak front will make its way south in the short term, stalling at our northern doorstep Thursday night as the supporting short wave trough scoots east, leaving the underlying front behind with little momentum. Still, lowered Friday high temps a skosh below the blend in anticipation of slightly cooler air reaching the ranchlands. The front will start to move back north a day or so later. The upper flow will remain southwest through the weekend with relatively quiet, albeit warming weather as southeast flow becomes more robust. A short wave trough will burrow through the Southwest United States and lift across North Texas on Monday into Monday night. This will bring another weak, underlying front through the region on Monday. High pressure will then spread across the region behind the front with slightly cooler weather through Wednesday under a fairly zonal upper flow.

MARINE: Now through Thursday Night: Conditions for dense sea fog will persist through much of the short-term period. A Dense Fog Advisory is currently in effect for the nearshore Gulf waters through 9 AM CST Thursday. Fog may push into the Laguna madre as early as late afternoon or early this evening. Otherwise, high pressure over the eastern Gulf will maintain light to moderate south- southeasterly flow. Winds will be breeziest during the daytime Thursday as diurnal heating tightens the pressure gradient along the coast. Other than sea fog, relatively favorable marine conditions will continue overnight tonight and through the day on Thursday, with wind speeds around 10 to 15 knots (occasionally higher) and wave heights around 3 to 4 feet.

Friday through Monday Night . Light to moderate southeast to south winds will hold up all the way through Monday. Moderate seas will occasionally trend higher, however, into small craft should exercise caution territory. A front due on Monday will shift winds to moderate northeast which will support moderate to high seas. Sea fog will be possible the next three mornings as the nearshore waters remain cool under higher dew point air.

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