NWS Brownsville, TX wrote its last area forecast discussion before the first event at Apr 24, 11:58 PM CST, 1 hour 42 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 1258 AM CDT Thu Apr 25 2019 .DISCUSSION...Updated for latest aviation discussion below. && .AVIATION...Light northwest winds and MVFR ceilings prevail across the Rio Grande Valley early this morning in the wake of the weak cold front. Brownsville radar currently indicates a strong thunderstorm just south of the Rio Grande River. Therefore, will mention a TEMPO for some convection at MFE. Otherwise, northwest winds around 10 knots and clearing skies are expected through this morning. Full VFR conditions are expected by mid morning and continue through the rest of the period. && .PREV DISCUSSION... /issued 249 PM CDT Wed Apr 24 2019/ ..Slight risk of severe weather across western and northern portions of deep south Texas tonight... SHORT TERM (Now through Thursday night): Satellite and radar images continue to indicate showers and thunderstorms across central portions of the state this afternoon as the 500mb low/trough across west Texas and northern Mexico moves slowly eastward. At the surface...a weak frontal boundary was draped across north-central Texas southwest towards Del Rio separating the moist and unstable airmass across south Texas. LAPS surface analysis currently showing lifting indices of -5 to -7 across northern portions of the CWA extending northward into the Rio Grande plains. Will likely see showers and thunderstorms...some possibly strong to severe...develop to the north and west of deep south Texas late this afternoon into this evening and move into the western portions of the CWA this evening. Will continue to mention large hail and damaging winds with severe storms tonight across portions of Zapata...Jim Hogg and Starr counties with the potential for severe storms as per the latest severe weather outlook from SPC showing a slight risk of severe storms across the northwest ranchlands. Will word gusty winds and small hail with storms elsewhere tonight except across southeast portions of the CWA where there is no marginal risk of severe weather and where the atmosphere is capped. Even though the risk of severe weather is limited across the lower and middle portions of the Rio Grande valley tonight, will keep a chance of rain through late tonight as a weak cold front moves through the area late tonight. As the the upper level low/trough moves eastward Thursday, west to northwest flow aloft will allow subsidence to increase across southwest Texas and drier air at the surface and aloft will bring an end to rain chances from west to east early Thurs morning and skies will clear from west to east Thursday. This will allow temperatures to warm into the upper 80s to lower 90s across the Rio Grande valley Thurs afternoon. LONG TERM (Friday through Wednesday): Mid-level ridging and high pressure will build over the area on Friday under sunny skies and with light winds and high temperatures mainly in the 90s. The mid level pattern will remain more or less zonal through the weekend with broad high pressure over the Gulf. A mid level cutoff low over the East Pacific will move east and lift into the Southwest United Sates on Monday. Diffluent southwest flow to the south of the low over the Sierra Madre range will begin to destabilize the atmosphere, though significant convection will not immediately develop. Good return flow will continue on Tuesday, and thunderstorms emanating from the front range will look a little more promising Tuesday night, with a repeat performance on Wednesday night. A few of the storms could move east and cross into the CWA. In the mean time a moderate to strong southeast to south wind will funnel moisture north into areas of more active weather upstream. Overall, look for plenty of sun and near average to slight warmer than average temperatures through the weekend. Southeast winds will increase to breezy and even windy near the coast heading into early next week, and cloudiness will increase with dewpoints pushing into the lower 70s. The higher dewpoints will keep overnight low temperatures above normal Monday night through Wednesday night. MARINE: Now through Thursday night: Seas were near 6 feet with southeast winds near 10 knots at buoy020 early this afternoon. Light to moderate south winds will prevail across the coastal waters tonight before a convective frontal boundary (weak cold front) moves offshore the lower Texas coast Thurs morning. Winds and seas will be higher in and near thunderstorms that develop along and ahead of the convective frontal boundary tonight into Thurs morning. Winds will shift to the north Thursday in the wake of the front. Light north winds will prevail across the lower Texas coast Thursday as surface high pressure settles across the coastal waters. Winds will begin to veer to the east Thurs night as a weak cold front moves into central Texas. Friday through Monday night: Light north winds on Friday will turn to southeast on Saturday. Southeast winds will increase to moderate over the weekend as high pressure spreads over the area and then shifts east. Seas will remain low to moderate through the long term. && .BRO WATCHES/WARNINGS/ADVISORIES... TX...None. GM...None. && This product is also available on the web at: HTTP://WEATHER.GOV/RGV 63
