| Area Forecast Discussion National Weather Service Corpus Christi TX 546am CDT Thu Oct 28 2021 /Issued 357am CDT Thu Oct 28 2021/ Short Term - Today Through Friday A high-amplitude trough just to the east with a surface high pressure to the west will result in a strong pressure gradient today. Winds will be strong to very strong across South Texas and over the Coastal Waters. Winds could gust to around 40 mph across the northeastern counties, so a Wind Advisory has been issued for today. Dry air will persist, with minimum RH values in the teens across the west and around 20 to 30 percent across the east. Though fuels are still green, finer fuels will be dry, so with the potential for Elevated Fire Weather conditions, so have issued an RFD for all counties except for Webb and La Salle counties from 15Z through 00Z. Winds should begin to diminish around midday Friday but will remain moderate to strong through Friday. Hopefully, this will help limit some of the Fire Weather concerns. With the continued north to northwesterly flow, cooler daytime temperatures are expected, with highs in the low to mid 80s for today and Friday. Clear skies will lead to a cooler night tonight, with lows in the upper 40s to mid 50s over South Texas. Long Term - Friday night through Wednesday Quasi-zonal flow will be the dominant synoptic pattern through the long-term period. Daytime temperatures will generally be in the 80s through the next week. Areas in the Rio Grande Plains may reach into the low 90s on Sunday. Nighttime temperatures will be cooler through the weekend, with lows falling into the mid 40s to mid 50s. Southeasterly flow will return Sunday, allowing nighttime temperatures to become more mild going into the work week. The aforementioned southeasterly winds will bring in slightly warmer and more humid air to start off the work week. Mostly clear skies will give way to partly cloudy skies as moisture increases in the mid-upper levels. Next shot at rain chances may be later in the week next week as another cold front approaches South Texas Thursday/Friday, bringing a slight chance of showers along with it. Lowered Probability of Precipitation from NBM and blended with the previous forecast, as uncertainty still remains with the timing and strength of the front, as well as with how much moisture will be available ahead of the front.
