NWS Brownsville, TX wrote its last area forecast discussion before the first event at Apr 5, 11:35 PM CST, 25 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 1235 AM CDT Tue Apr 6 2021 .DISCUSSION...Updated for latest aviation discussion below. && .AVIATION...VFR to MVFR conditions are expected tonight as low level moisture increases, especially near sunset. Southeasterly winds become breezy to gusty by late Tuesday morning and remain gusty through Tuesday evening, with gusts to 25-30 kts. VFR ceilings likely return mid to late morning through the afternoon, before MVFR ceilings return again into Tuesday night. && .PREV DISCUSSION... /issued 645 PM CDT Mon Apr 5 2021/ DISCUSSION...Updated for latest aviation discussion below. AVIATION...Low level moisture continues to flow inland maintaining an influx of cloud cover. Ceilings become predominate MVFR at or shortly after sunset continuing through mid to late morning Tuesday. Daytime heating allow for ceilings to lift in the afternoon with VFR resuming. Not anticipating any restrictive fog with winds remaining high enough to keep vsby above 5 miles. Gusty southerly winds slowly decouple this evening with a light to moderate flow overnight. Stronger southerly flow develops Tuesday with late morning and afternoon gusts of 20-30 knots. PREV DISCUSSION... /issued 244 PM CDT Mon Apr 5 2021/ SHORT TERM (Tonight through Tuesday Night): A shortwave will continue to progress eastward tonight with any rain chances that remain along the coast diminishing this evening with dry conditions expected for the remainder of the short term. A surface low developing across the central High Plains today will begin to shift southeastward leading to increased southerly winds this evening and especially on Tuesday. Winds look to remain just under Wind Advisory Criteria Tuesday but will continue to monitor and will issue an advisory if needed. RH values will remain too moist for Fire Weather criteria but with the high winds on Tuesday this will still pose a increased fire weather threat. Temperatures will remain warm overnight with lows in the upper 60s. Tuesday temperatures will be warmer than today with highs ranging in the mid 90s out west to mid 70s along the coast and overnight lows in the upper 60s to low 70s. LONG TERM (Wednesday through Monday): Conditions will remain breezy along the coast on Wednesday, courtesy of lower pressure in the Plains and North Texas interacting with persistent high pressure extending across the Gulf of Mexico. Relative humidity values below 30 will develop Wednesday afternoon across the northwest third of the CWA, but 20 ft winds look to be below those supportive of a critically enhanced wildfire growth and spread threat. A front will extend as far south as East Texas Wednesday night, but with little impact to deep South Texas and the RGV. In fact, East Pacific ridging through the end of the week will support a dry northwest mid level pattern, limiting all but relatively quiet weather. A northern Plains storm system will send a front south into Texas Friday into Saturday night, but the front will stall out north of the CWA on Saturday. Above normal temperatures will persist through the long term, with afternoon high temperatures running 5 to 10 degrees above normal and overnight lows running about 5 degrees above normal. Rain chances will remain very low and not currently mentionable in the long term forecast. MARINE: Now through Tuesday Night...Southerly flow will continue in the short term with slowly building seas. As low pressure over the central US begins to move southeast this evening into Tuesday marine conditions will begin to deteriorate as the pressure gradient tightens. Small craft will need to exercise caution on the Laguna Madre and Gulf waters late tonight into Tuesday night with possible Small Craft Advisories needed as winds increase and seas continue to build on Tuesday afternoon into the overnight. Wednesday through Saturday Night...Exercise caution conditions will be possible on Wednesday with persistent higher southeast winds and elevated seas. This will be the result of Plains low pressure interacting with higher pressure over the Gulf. A weaker pressure gradient will prevail the latter half of the week after Wednesday, and into the weekend. This will result in mainly moderate southeast winds and moderate seas for the marine areas. && .PRELIMINARY POINT TEMPS/POPS...
