Area Forecast Discussion...UPDATED National Weather Service Brownsville TX 1228 AM CDT Wed Nov 1 2017 ...06z Aviation Update... .DISCUSSION...Updated for latest aviation discussion below. && .AVIATION...Broken to overcast skies will continue overnight and into Wednesday. Low stratus will send our categories down into the MVFR range at times through the morning. Some improvement is then expected by afternoon to VFR. Winds should remain mostly out of the south with the exception of MFE. MFE has shifted northerly at least briefly as a weak frontal boundary has moved through that area. Winds should eventually shift back southerly by this afternoon. && .PREV DISCUSSION... /issued 1025 PM CDT Tue Oct 31 2017/ DISCUSSION...Have updated the forecast to adjust pops and temps a bit reflecting recent radar and ob trends. Have also opted to remove the mention of locally heavy rainfall for the overnight period as current radar trends indicate only fairly light to moderate shower activity lingering over the region. PREV DISCUSSION... /issued 242 PM CDT Tue Oct 31 2017/ SHORT TERM (Tonight through Wednesday Night): Scattered showers and isolated thunderstorms continue to develop along a weak frontal boundary draped across south Texas this afternoon. Some showers are developing across the northeast portions of the CWA this afternoon with most of the convection confined across the coastal waters. The question is how much the convection across the western Gulf of Mexico will influence rain chances across the Rio Grande valley and northern ranchlands the rest of the afternoon into this evening. Even with a 500mb shortwave trough across west TX moving eastward tonight...believe most of the upper level support will be north of the area. There is a small window for thunderstorms with heavy rain...mainly across the coastal sections...this afternoon into early this evening but once we lose diurnal heating the threat for heavy rainfall diminishes rapidly. The weak frontal boundary will move into the CWA tonight and this will provide a focus for showers...mainly across the eastern portions of deep South TX...so will keep a chance of rain for this evening. Rain chances will diminish from west to east late tonight into Wednesday as the weak frontal wave across south TX weakens and moves eastward. Will likely continue to see showers and thunderstorms across the coastal waters tonight through Wednesday before drier air finally moves across the western Gulf of Mexico Wed night. LONG TERM (Thursday through Tuesday): Mid level zonal flow will continue over Texas on Thursday. A 500mb ridge will build westward and remain centered over northern Mexico and south Texas Friday through early next week. Subsidence will increase across deep south Texas as the ridge builds overhead. Low level moisture, mainly below 850mb, will keep dew points high for early November. Lingering moisture may support very isolated showers near the coast Thursday. Otherwise, rain-free conditions are anticipated through the period. Day time and night time temperatures will remain well above normal for the long term. High temperatures will generally range from the mid 80s near the coast to the low to mid 90s inland. The combination of high dewpoints and the above normal temperatures will lead to heat indices nearing and exceeding 100 degrees each day. Overnight low temperatures will generally be in the upper 60s to the lower 70s area-wide. MARINE (Tonight through Wednesday night): Seas were near 6 feet with east to southeast winds near 18 knots at buoy019 and near 3 feet with east to southeast winds near 16 knots at buoy002 this afternoon. Moderate to strong south to southeast winds will prevail across the western Gulf of Mexico tonight even with a weak frontal boundary draped across the Texas coast. Will continue to mention SCEC for the offshore waters tonight for high winds and seas. The pressure gradient will weaken across the coastal waters Wednesday. Light to moderate south to southeast winds will prevail across the western Gulf Wednesday but will increase Wed night as low pressure across the TX panhandle allows the pressure gradient to increase across the lower TX coast. Thursday through Saturday Night...Broad surface high pressure across the Mid-Atlantic states extending into the Gulf of Mexico will support moderate southeast wind and low seas through the period. Isolated showers will be possible across the Gulf waters on Thursday due to some lingering low level moisture. Otherwise, little to no rain is expected through the weekend. && .BRO WATCHES/WARNINGS/ADVISORIES... TX...None.
