NWS Brownsville, TX wrote its last area forecast discussion before the first event at Apr 30, 11:32 PM CST, 28 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 1232 AM CDT Mon May 1 2023 ...New AVIATION... .SHORT TERM... (Tonight through Monday night) Issued at 231 PM CDT Sun Apr 30 2023 Dry and slowly warming temperatures, especially at night, are on deck through the short term. Lows tonight are expected to be in the lower to middle 60s as winds turn more southeasterly. Daytime highs Monday climb into the upper 80s to lower 90s across the area before dipping into the upper 60s to near 70 Monday night. Rain chances remain out of the forecast thanks to high pressure overhead. Wind may be a concern during the day Monday. A couple of models are indicating wind gusts nearing 40 mph at times tomorrow, which is close to Wind Advisory criteria. Confidence isn't quite there to have gusts that high in the official grids, but it's close. Interestingly, the hallmark for Wind Advisories here is the presence of a strong low-level jet (LLJ), but that will be lacking tomorrow as most guidance suggests a LLJ between 20 to 30 knots. So, for now, we'll monitor how tight the pressure gradient gets Monday and call for gusts between 30 to 35 mph. That may be strong enough to delay some of the ongoing power restoration efforts across the Valley. It's also worth mentioning that an area or two of fog cannot be completely ruled out the next few nights. The biggest hindrance to any fog formation would be elevated winds. The combination of high pressure overhead leading to mainly clear skies most of the night and increasing surface moisture means we cannot completely rule fog out. The SREF and HREF are indicating a 10 to 20 percent chance of fog forming along in the Lower Rio Grande Valley. && .LONG TERM... (Tuesday through next Sunday) Issued at 231 PM CDT Sun Apr 30 2023 The long term forecast will lack major weather systems affecting the CWA. A large, upstream mid- level ridge over the Rockies will shift east mid-week, weakening a bit and allowing some energy to burrow through the base of the ridge and move over the Southern Plains and North Texas. In the meantime, however, light to moderate onshore flow will persist, gradually increasing low level moisture across deep South Texas. Coastal PWAT values could approach two inches Wednesday and Thursday. The moisture and instability could support afternoon seabreezes Wednesday and Thursday, along with Sierra Madre Oriental front range thunderstorm development. The NBM brings a mention of thunderstorms to inland areas just about every afternoon and evening in the long term. Looking to later in the week, the major upper low over the Southwest United States that was sending energy east will have lifted north, letting the local mid-level flow stabilize a bit. Friday may be a quieter weather day, though the NBM still paints in isolated convection. Looks like instability will continue to trigger Big Bend and front range convection Saturday afternoon and again Sunday afternoon. The diurnally driven front range convection will tend to drift east, with the ongoing threat for a few storms to move into the CWA. High temps on Tuesday and Wednesday will generally be in the 80s, but average high temps will drift on up into the 90s after that. Similarly, low temps will start out in the upper 60s to near 70, but will edge on up into the lower 70s area wide after mid-week. && .AVIATION... (06Z TAFS) Issued at 1229 AM CDT Mon May 1 2023 VFR through the period with southeasterly winds becoming breezy gusting up to 30 mph by late morning through the afternoon. && .MARINE... Issued at 231 PM CDT Sun Apr 30 2023 Now through Monday Night...Favorable marine conditions continue through tonight with winds turning more southeasterly as the night progresses. A tightening pressure gradient along the Lower Texas Coast may lead to Small Craft Advisory conditions Monday morning into early Monday afternoon. However, confidence wasn't high enough to issue one at this time. A relaxing pressure gradient later Monday afternoon should bring a return of more favorable marine conditions Monday night. Tuesday through Friday Night...Light to moderate east to southeast winds and moderate seas will prevail through the period. Isolated showers will arise from time to time. Mid-level ridging and surface high pressure will support a relatively quiet weather regime. && .PRELIMINARY POINT TEMPS/POPS...
