Area Forecast Discussion . UPDATED National Weather Service Brownsville TX 613 PM CST Fri Jan 24 2020

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. VFR conditions will continue through the night with increasing clouds expected through the day on Saturday as southeast flow increases. Moisture will increase and deepen ahead of an approaching upper-level disturbance. This will lead to deteriorating ceilings with MVFR conditions developing. Models indicate rain chances also increasing with showers possibly lowering visibilities at times, especially Saturday afternoon and night.

PREV DISCUSSION. /issued 249 PM CST Fri Jan 24 2020/

SHORT TERM (Tonight through Saturday Night): Uneventful weather tonight will turn a little more unsettled on Saturday and Saturday night. Weak mid level ridging overhead will break down as a southern High Plains short wave trough moves across Oklahoma during the period, while another weakly connected short wave trough over Baja moves similarly east over Central Mexico. A tighter surface pressure gradient will enhance low level return flow and moisture Saturday, while instability embedded in the southwest flow in advance of the Baja upper feature will support lift late Saturday, from afternoon to Saturday night. A time height profile shows dry air being replaced by a deep column of moist air Saturday morning through afternoon. The ingredients will be enough to support showers and a few moderate strength embedded thunderstorms. Unorganized showers will produce moderate rainfall, with localized amounts up to an inch, but here and there amounts of slightly higher value will be possible. The presence of low level moisture, not to mention wet ground, and lighter winds will increase fog potential Sunday morning. Will see increasing cloudiness tonight, with cloudy skies by Saturday and Saturday night. Temps will be slightly above normal overall, but may be tempered locally by rain.

LONG TERM (Sunday through Friday): Another pretty strong 500 mb short wave will push through TX Tues which will likely spin up a surface low near the TX coastline Tues Night. Overall moisture levels will remain pretty limited as this system moves through the region. So will maintain only some low end pops on Tues. As this system exits the region, another fairly large 500 mb trough/closed low is expected to move into the state late Thurs into Fri which will increase the divergence aloft across the RGV Thurs into Fri. Once again, overall moisture levels associated with this system will remain somewhat marginal for the end of the work week. However, the good 500 mb PVA associated with this system will likely overcome the limited moisture levels to allow for some decent pops by the end of next week.

The relatively progressive west to east 500 mb flow pattern over the lower 48 states will maintain overall temps near to above climo for late January. CAA will likely remain pretty limited across the region.

The GFS and the ECMWF models are in reasonable agreement in the overall pattern through Day 7/8 for both temps and pops. Run to run consistency with both models are also pretty stable. So will stick close to a general model blend for next week.

Overall forecast confidence is above average in the longer range period.

MARINE (Now through Saturday night): Moderate to breezy southeast winds and higher seas will develop on Saturday and Saturday night due to a tighter pressure gradient. Small craft will need to exercise caution, with wave heights potentially bordering low end small craft advisory criteria Saturday night on the open Gulf waters. Upper instability will also kick off showers and possible thunderstorms during the latter portion of the short term.

Sunday through Wednesday Night: The PGF may strengthen enough to push the Gulf conditions up close to SCA levels early Sun as the surface low pressure area impacts the TX coastline. The PGF will then decrease enough next week to allow for fairly low winds and seas to prevail through Tues. Another round of SCA conditions may develop around midweek of next week as the next surface low pressure area develops/moves offshore of the lower TX Tues Night/Wed. The PGF will then relax some Wed Night as the marine surface low shifts eastwards across the Gulf of Mex.

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.
