NWS Brownsville, TX wrote its last area forecast discussion before the first event at Jun 1, 2:46 PM CST, 1 hour 14 minutes earlier.
Area Forecast Discussion National Weather Service Brownsville TX 346 PM CDT Mon Jun 1 2020 .SHORT TERM (Now through Tuesday night): The main story today has been the latest round of showers and thunderstorms across South Texas thanks to an upper-level trough/mid-level low centered over the Texas Big Bend. Ongoing convection has been producing a quarter of an inch to a half inch in most activity. Some locations have picked up 1 to 2 inches locally. With above-normal precipitable water values, any training of storms may produce localized flooding through the rest of the afternoon. By sunset, activity should begin decreasing in coverage. However, isolated activity will continue overnight as the main upper-level trough lifts gradually northward. Tuesday, upper-level support moves away from the region, but surface flow will be light out of the east. Combining with continued deep moisture, another round of showers and storms is expected mid- morning through the afternoon. Coverage should less than today, but PoPs will range from 30 to 40% area wide. Many areas of picked up quite a bit of rain in the last several days, so any additional heavy rainfall may cause minor flooding issues. Temperatures are expected to be a few degrees warmer than today with highs reaching to around 90 degrees. .LONG TERM (Wednesday through Monday):Models remain persistent and in relative good consistency in building a strong mid-level ridge across the Northern Mexico, Desert SW and West Texas Wed into Saturday. While a mid- level pressure trough roughly aligns along 90W from the Bay of Campeche through Louisiana. To say the least these mid-level features will have a lot to do with the steering flow of any tropical disturbances that may for over the next few day. Currently model consensus indicates very slow northward movement of newly formed tropical Depression 3, off the west Yucatan Peninsula, with some potential strengthening as this system moves every so slowly north or northwest. Model trends this system or even a completely different entity northward along the mid-level trough axis through Sunday. GFS/EC than builds the upper ridge north of either TD 3 or the other potential tropical cyclone and slows its northward progression by the end of the Long term. Confidence in this scenario is about average with a lot of uncertainty in the eventual movement and development of TD 3 or the model indicated tropical system. In any case, and if the northerly track does plays out rain chances for out CWA will continue to decrease and temperatures go up as the mid-level ridge building in from the west becomes the more dominate player in our weather. Forecast continues to show decreasing rain chances Wednesday with more of sea breeze regime setting up for Thursday and Friday. Temperatures are likely climb above average by Thursday or Friday. && .MARINE:(Now through Tuesday night): The main marine hazard through Tuesday will be any showers and storms that move over the waters, which may produce locally strong winds to 30 knots and cloud to water lightning. Outside of convection, a weak pressure gradient should result in light to moderate easterly winds and seas of 4 feet or less. Wednesday through Saturday...At the beginning of the long-term general light to moderate easterly wind and a low sea regime continues with weak high pressure over the northern Gulf of Mexico. The surface ridge remains in place with fair marine conditions persisting through Friday. Thunderstorms coverage is indicated to diminish but can not rule occasional stronger thunderstorms producing gusty winds and heavy rainfall. Uncertainty works its way into the marine forecast for next weekend as new formed Tropical Depression 3, over the Bay of Campeche, may trend northward with time. Forecast currently keeps this system east of the Lower Texas coastal waters, however, higher seas may impact the Gulf water next weekend. In any case, mariners should stay tuned to the latest marine forecast issued by the NWS office in Brownsville and the National Hurricane center for the latest updates. && .PRELIMINARY POINT TEMPS/POPS...
