Area Forecast Discussion National Weather Service Brownsville TX 302 PM CDT Wed Apr 1 2020
.SHORT TERM (Now through Thursday Night): Shallow 500 mb ridging will build over Mexico and southern TX throughout tonight. A series of 500 mb vort maxes will then move over the top of the ridge axis on Thur/Thur Night. This will tend to shift the ridge axis farther eastwards shift the 500 mb pattern to a more zonal configuration. A surface low pressure system in the central Plains States will start increasing the overall moisture levels across the RGV through Thurs Night. This will likely increase the overall cld cover throughout the short term. But with most of the 500 mb PVA remaining confined to the north of the region, will not go with any significant pops.
As the WAA increases across the region, all of the short term temp guidance increases throughout the period with the ECMWF guidance being the most aggressive with the warmup. Will go close to a model blend with a lean towards the warming side of guidance.
.LONG TERM (Friday through Wednesday): With a surface low moving over North Texas and surface ridging over the eastern CONUS, low to mid-level moisture will continue to stream into the region heading into the weekend with a southeasterly flow. As the wide trough over the western CONUS moves eastward into the central portions of the country, the surface low over North Texas will also move eastward and drag a cold front across the state on Friday. The front is still expected to stall just north of our area on Saturday. The main concerns continue to be the potential for severe weather for Deep South Texas and heavy rainfall, especially for the northern ranchlands Friday night into Saturday. As mentioned in this morning's discussion, SPC has a marginal threat of strong to severe thunderstorms on Friday for all of Deep South Texas and the Rio Grande Valley. Forecast soundings show notable instability Friday and Saturday, especially for the northern ranchlands. Even though heavy rainfall is possible with this activity, flash flooding is not a primary concern, considering the current severity of drought and the ground's capacity to absorb much of the rainfall before runoff becomes an issue. Rain chances continue into Sunday, but will likely be more elevated in nature as high pressure builds into the region.
Heading into next week, the-mid level ridge parks over the Gulf, leaving us under a southwesterly flow aloft. Slight rain chances linger each day, primarily out west, with ample surface moisture due to the southeasterly surface winds and weaker subsidence over those areas. As for temperatures, warm to very warm conditions will continue through the long term, with a slight decrease this weekend with the expected rain and cloud cover, and then very warm temperatures continue into next week.
MARINE: Now through Thursday. With the PGF increasing gradually especially along the lower TX coastline, there will be the potential for SCEC conditions mainly along the Bay waters for tomorrow afternoon. Gulf swells may build up offshore close to SCEC criteria also mainly for Thurs Night.
Friday through Wednesday . Besides the potential for strong to severe thunderstorms this weekend as a front stalls just north of the area, generally favorable marine conditions are expected in the long term with low to moderate wave heights and light to moderate east-southeasterly winds.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
