Synopsis for the middle texas coastal waters.. Weak to moderate onshore flow continues tonight ahead of a weak cold front. Following patchy fog across the bays and nearshore waters tonight and early Friday morning, the front will move across the waters by mid to late morning ahead of mostly weak northerly flow. Offshore flow will remain weak Saturday as high pressure settles into the region, before weak onshore flow returns Saturday night into Sunday. The flow will strengthen to moderate levels Sunday night into Monday in advance of the next cold front. The front will push offshore early Tuesday morning with small craft advisory conditions likely over the gulf waters Tuesday through Tuesday night. Scattered showers will affect the coastal waters Monday night into Tuesday.

DISCUSSION.

06Z aviation discussion follows.

AVIATION.

Fog and stratus are slower to develop tonight thus far, but a deck of IFR stratus with some dense fog is expanding north from the Rio Grande Valley and will likely impact ALI, LRD and potentially CRP by 2 to 4 AM or so. Although COT and VCT will be displaced from this primary IFR threat, VCT should see its own IFR conditions at times overnight before a weak cold front by mid morning swings winds to the north and restores VFR conditions region wide.

PREV DISCUSSION. /Issued 318 PM CST Thu Dec 5 2019/

SHORT TERM (Tonight through Friday Night) .

A little warmer and more humid with increasing moisture/clouds/fog expected tonight. A weak frontal boundary is expected to move across S TX through the early Fri morning hours and exit to the south by mid to late Fri morning. Not much CAA nor drying initially with this front with dewpoints remaining elevated through early Fri morning. This low level moisture combined with light winds will be conducive for fog formation overnight. Could see visibilities drop to 1/4SM in some locations, especially across the interior Coastal Plains and Brush Country. There is some uncertainty with how dense the fog will become due to slightly elevated wind speeds. If the denser fog becomes more widespread and persistent, then a Dense Fog Advisory may be needed later tonight or early Fri morning.

Drier air will begin filtering into the northern CWA Friday morning and continue advecting southward through Fri afternoon. This will lead to decreasing clouds from north to south through the day. With lack of CAA and a drying airmass, Fri will be a warm day with above normal temps.

Models prog surface high pressure to continue to build across S TX Friday night with CAA and continued drying. This will lead to mostly clear skies and a chilly Fri night with lows near normal.

LONG TERM (Saturday through Thursday) .

A broad upper level ridge over the southern plains Saturday will move east and dampen over the southeastern US Sunday as the next upper level trough swings into the Great Basin. The surface ridge axis over south Texas on Saturday will move east Saturday night. A weak to moderate onshore flow will occur Sunday and increase slightly by Monday as low pressure moves across the southern plains. Temperatures will steadily warm up from Saturday through Monday with highs well above normal with readings in the lower to mid 80s.

GFS and ECMWF are not in agreement with regards to movement of the upper level short wave trough over the Great Basin early next week. The GFS is progressive with this energy quickly merging with the deep upper trough moving from the northern plains into the upper Midwest Monday into Tuesday. The ECMWF (and Canadian) show an upper low forming over the Desert Southwest Monday moving toward Far West Texas Tuesday. Former scenario will lead to a brief rain chance with the cold front Monday night/Tuesday morning, the latter with a much better chance for rain over a longer period (Tuesday-Wednesday) and a little slower timing for the front. Will lean toward the drier solution at this time. Will show chance PoPs mainly over the coastal plains Monday night into Tuesday with the cold front moving through the area early Tuesday morning. Will hold on to slight chance PoPs over the coastal areas Tuesday night into Wednesday in case the ECMWF solution pans out. Temperatures will be much cooler for Tuesday and Wednesday with highs in the lower to mid 60s. With low confidence in forecast for Tuesday/Wednesday period, went with a gradual warming trend for Thursday.

MARINE .

Weak to moderate onshore flow expected tonight ahead of a weak cold front. The frontal boundary will move across the waters Friday morning. Patchy fog is expected across the bays and nearshore waters ahead of the frontal boundary late tonight and possibly lingering behind the boundary through late Friday morning before drier air advects across the area. Behind the frontal boundary, a weak to moderate offshore flow will develop through Friday and will continue through Friday night. The offshore flow will continue to weaken Saturday as the high pressure ridge settles into the region. Winds will become weak onshore Saturday night into Sunday. The flow will strengthen to moderate levels Sunday night into Monday in advance of the next cold front. The front will push offshore early Tuesday morning with SCA conditions likely over the Gulf waters Tuesday through Tuesday night. Scattered showers (even isolated thunderstorms Monday evening) will affect the waters Monday night into Tuesday.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
