Area Forecast Discussion National Weather Service Brownsville TX 608 AM CDT Fri Aug 14 2020

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. Fair flying conditions for all of Deep South Texas and the three Rio Grande Valley airports as high pressure remains in control. VFR conditions expected the next 24 hours with generally light southeast to south winds with an occasional afternoon gusts up to 20 knots.

PREV DISCUSSION. /issued 310 AM CDT Fri Aug 14 2020/

SHORT TERM (Now through Saturday): Persistence is the best forecast with latest model suite insisting that the position of the 500mb subtropical ridge remains anchored over Arizona extending well into Texas. Atmosphere continues unusually dry for Mid-August with 1000-500mb mean RH ranging from 30-45 percent today and Saturday, hardly enough to warrant any mentionable PoPs. Surface pressure gradient remains slack as broad surface ridge over the Gulf is rather weak but sufficient to preserve slight afternoon breezes. Finally, temperatures stay the course with mid- August normals having been met for much of this week and will be maintained through the first half of the weekend. Also, heat index values remain in check ranging from 100 to 107 due to forecast of lower daytime relative humidity.

LONG TERM (Saturday Night through Thursday): The subtropical ridge holds through the weekend across Texas. A shower or thunderstorm may develop along the seabreeze Monday, as moisture increases across South Texas. The ridge hikes northwestward across the Rockies into early next week as a trough across the eastern CONUS deepens through the Southeast. A frontal boundary tries to work into Texas Monday night into Tuesday, with a brief and weak wind shift possibly reaching into Deep South Texas. Coastal low pressure develops and sits along the lower Texas coast through late next week.

The best chance of rain still resides along the seabreeze Tuesday through Thursday, including whatever boundary collisions happen as a result of the seabreeze, wind shift, and any remnant outflow boundaries working south. Mid-level disturbances rounding the ridge and western edge of the trough would also add bouts of instability to the mix through late week. PWAT values climb to around 1.8 to 2.0 inches Tuesday afternoon into Tuesday evening, leading to the potential for slow moving efficient rain producing showers or thunderstorms, if they can develop. Temperatures remain warm and seasonal this weekend to a couple of degrees below normal by mid next week. The calm conditions Monday night, combined with increasing moisture, may help fog develop and settle in, especially across the northern ranchlands. Patchy fog may be possible into mid or late next week with continued light to calm winds at night.

MARINE (Now through Saturday): Weak high pressure over the Gulf of Mexico holds firm with little change in the overall Marine forecast for the Lower Texas coast. Light onshore flow providing favorable seas offshore and a light chop on the bay can be expected today and Saturday.

Saturday Night through Thursday: High pressure remains in control across the Gulf of Mexico through this weekend, with light to moderate southeasterly onshore flow generally expected through the period, yielding very favorable marine conditions. A weak wind shift and frontal boundary may approach the region Monday night into Tuesday. The chance of showers and thunderstorms increases Monday night and continues into Thursday as moisture and instability increase across the northeastern Gulf of Mexico with a weak coastal trough of low pressure developing.

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.
