Synopsis for the middle texas coastal waters.. An upper level disturbance will contribute to isolated showers and Thunderstorms today. Drier tonight and Monday. Generally weak flow today, then weak to moderate onshore flow tonight and Monday. Weak to moderate onshore flow will continue Monday night into Tuesday ahead of an approaching cold front. By Tuesday afternoon winds are expected to subside to weaker levels as the front sweeps across south texas. Behind the front, moderate to strong northerly winds are expected Wednesday morning with winds subsiding to more moderate levels by Wednesday night. Therefore, small craft exercise caution conditions or a small craft advisory will be possible Wednesday. With an increase in moisture ahead of the cold front, scattered to numerous showers and Thunderstorms will be possible Tuesday afternoon through Tuesday night.

AVIATION.

Brief MVFR visibilities over portions of the Coastal Plains early this morning. Afterward, VFR conditions are expected, except brief MVFR conditions near isolated showers/thunderstorms mainly over the Victoria Crossroads this afternoon. Light/variable wind early this morning, becoming weak/moderate onshore late this afternoon/early evening, followed by a transition back to light/variable 06-12z Monday.

PREV DISCUSSION. /Issued 435 AM CDT Sun Sep 19 2021/

SHORT TERM (Today through Monday) .

Deterministic runs predict the upper trough/low, with N-S axis currently along the TX coast, to lift east/northeast during the period, while another upper disturbance enters the Plains. Anticipate that the proximity disturbance will contribute to isolated convection mainly over the Victoria Crossroads today, with moisture as the limiting factor (most recent GOES-16 TPW depicts greatest PWAT values over the Victoria Crossroads, with values around 1.6 inches which is slightly below normal.) Drier conditions expected tonight/Monday owing to increasing subsidence/drying over the CWA behind the upper disturbance. Maximum Heat Index values generally 100-105F today, yet 105-109F Monday. Water levels have risen to around 1.5 ft MSL, likely in response to the nearness of the full moon. However, given do not expect levels to reach 2 ft MSL, when considering expected wind/sea state and ETSS output.

LONG TERM (Monday Night through Saturday) .

Weak ridging in the upper levels is expected to continue trough Tuesday before the passage of the expected cold front. Models are beginning to come into better agreement in regards to the timing and intensity of the cold front. The GFS/ECMWF/NAM are now showing the frontal passage Tuesday night with the front pushing all the way through Deep South Texas Wednesday. As the cold front approaches South Texas Tuesday night, models are showing deeper moisture being ushered into South Texas with PWATs ranging from 2.0 to 2.16 inches (75th percentile climatological mean). With the deeper moisture and lifting due to the front, scattered to numerous showers and thunderstorms will be possible Tuesday afternoon into Tuesday night. With an upper level ridge building into South Texas behind the front, subsidence will lead to clear skies with minimal chances of precipitation Thursday through the weekend.

With weak ridging ahead of the cold front, temperatures are expected to be slightly warmer Tuesday with highs ranging from the mid 90s to near 102 degrees. The combination of warm temperatures and moisture will lead to heat indices ranging within 105 and 109 degrees across South Texas. Behind the front max temperatures will be cooler, with highs ranging from the mid 80s to lower 90s Wednesday through Friday. By Saturday, max temperatures are expected to warm into the upper 80s near the coast to the mid 90s out west. With cooler air filtering into South Texas behind the front, low temperatures Wednesday night are expected to dip into from the upper 50s to the upper 60s. With the increased subsidence and clear skies, radiational cooling is expected to continue into the weekend with lows maintaining in the lower to upper 60s.

MARINE .

An upper level disturbance will contribute to isolated convection today. Drier tonight and Monday, as the upper system moves east. Weak to moderate onshore flow expected to develop tonight and Monday as low pressure deepens over the Southern Plains. Weak to moderate onshore flow will continue Monday night into Tuesday ahead of an approaching cold front. By Tuesday afternoon winds are expected to subside to weaker levels as the front sweeps across South Texas. Behind the front, moderate to strong northerly winds are expected Wednesday morning with winds subsiding to more moderate levels by Wednesday night. Therefore, Small Craft Exercise Caution conditions or a Small Craft Advisory will be possible Wednesday. With an increase in moisture ahead of the cold front, scattered to numerous showers and thunderstorms will be possible Tuesday afternoon through Tuesday night.
