GMZ100 Synopsis For Baffin Bay To Rio Grande Out 60 Nm- 915 Pm Cdt Sun Sep 19 2021
Synopsis..Weak high pressure located in the gulf of mexico will continue to provide light and a south to southeast wind with low seas through Monday. Low pressure will develop over the central plains Monday afternoon, which will act to strengthen the pressure gradient across the lower texas coastal waters. This will lead to increasing winds and seas through the middle of the week. Showers and Thunderstorms will develop across the coastal waters Tuesday and increase in coverage Tuesday night into Wednesday as a weak cold front moves offshore the lower texas coast Wednesday morning.

Area Forecast Discussion National Weather Service Brownsville TX 637 PM CDT Sun Sep 19 2021
DISCUSSION. Updated for latest aviation discussion below.
AVIATION. VFR conditions are expected to prevail through the majority of the TAF period. A touch of fog may develop and reduce visibility a bit around KHRL early Monday morning, but it shouldn't be widespread nor linger much past sunrise. Subsidence and dry air will keep Deep South Texas in VFR conditions Monday with winds picking up around lunchtime.
PREV DISCUSSION. /issued 250 PM CDT Sun Sep 19 2021/
SHORT TERM (Tonight through Monday Night): Subsidence is expected through the short term due to a 500mb trough across eastern Texas into the Lower Mississippi Valley and northwesterly winds aloft. This will continue to lead to hot and dry conditions across the CWA with light to moderate south to southeasterly winds. Temperatures on Monday will be hot again with highs in the 100s out west to 90s east with heat indices between 105 and 110 across most areas. A few isolated spots in Starr and Zapata counties could briefly see heat indices exceeding 110. Overnight lows tonight and Monday night will fall into the 70s across the region.
LONG TERM (Tuesday through Sunday): A deep mid-level trough moves over the northern plains Tuesday into Wednesday and brings one of the first cold fronts of the season to Deep South Texas. The strong positively-tilted trough allows for a surface cold front to move through southern Texas bringing in below normal temperatures and rain for overnight Tuesday into Wednesday. As far as model guidance for the front goes, ECMWF/GFS have a strong front moving into the CWA at 6z while the NAM has a slower and weaker front moving into the area at 9z. Went with a combination of the NBM and NAM to capture the best timing for the front. Rain chances increase by 12z Tuesday and are forecast to dissipate around 0z Thursday. PWAT values are at about 2 inches for the most of the CWA. Temperatures for Tuesday afternoon will be above normal for the area before the front moves through that night. As for Wednesday and Thursday, expect temperatures to be in the mid and upper 80s for Deep South Texas with lows in the lower 60s and dewpoints dropping into the upper 50s. As the trough exits the region, a ridge builds in the SW CONUS by Friday which allows for much drier conditions and near normal temperatures and dewpoints through the rest of the period.
MARINE (Tonight through Monday Night): Favorable marine conditions are expected through the period. Light to moderate winds will prevail through Monday night, with seas of generally 1 to 3 ft increasing to 2 to 4 ft Monday evening. An isolated shower or thunderstorm on Monday night could lead to localized increased winds and elevated seas.
Tuesday through Sunday: For the start of the forecast period, weak to moderate seas are expected between with waves between 2-3 feet and light to moderate winds. Once the front pushes through the area, showers and thunderstorms are expected over the Gulf Waters. Winds will increase causing seas to increase to about 4- 5 feet for Wednesday. Small Craft Exercise Caution may be needed for Wednesday and Thursday following the FROPA.
