DISCUSSION 12Z aviation discussion follows.

AVIATION Stratus and occasionally poor visbys in fog will continue for a couple more hours at ALI, VCT and COT, but ceilings may have a harder time recovering toVFR until late morning. Else, southerly winds will ramp up to around 20 knots toward noon at most terminals before scaling back tonight. Except at CRP, confidence is high that another round of low ceilings develops overnight and holds mostly at MVFR territory.

PREV DISCUSSION Issued 353 AM CST Wed Nov 20 2019 SHORT TERM (Today through Thursday)...

Following a less robust round of fog this morning, deep layer moisture will be on the uptick as an axis of PWATs around 1.4 inches expands over much of South Texas. However, ascent will be in short supply thanks to weak upper ridging remaining in the vicinity and more importantly a stout inversion around 850 mb. The one exception to this looks to be well offshore where a N-S axis of speed convergence should garner some shallow convective showers through the day. Some of this activity may drift north and graze our locales along Matagorda Bay, but the HREF and regional models favor the brunt of this precip holding farther east. Southerly gradient winds meanwhile should amplify to between 20 and 25 knots this afternoon in response to a sharpening surface trough in West Texas.

Fog should be even more scarce overnight into Thu morning as southerly winds hold around 10 knots or higher while high clouds thicken with the arrival of a subtropical jet just north of our region. Even as SW flow aloft increases and PWATs rise to around 3 4" above normal, ascent tomorrow once again looks to be seriously compromised by a stout EML camping out within the 850-800 mb layer.

Beneath this capping tonight and Thu, model soundings from the Victoria Crossroads to Matagorda Bay show some windows for shallow instability showers at times along an axis of speed convergence, so have kept 20 PoPs for these areas.

LONG TERM (Thursday Night through Tuesday)...

Upper level low over southern California will shift eastward into the Central Plains at the beginning of the extended, sending an associated cold front through South Texas Friday afternoon. Showers and a few thunderstorms will be possible ahead and along the advancing boundary Friday, but will be mostly limited to the eastern half of the CWA where higher moisture content will reside. Due to the timing of this front, temperatures on Friday will be able to warm into the upper 70s to mid 80s ahead of the boundary, before falling into the upper 40s to mid 50s by Saturday morning in its wake. Rain chances will quickly diminish by early Saturday as high pressure builds across the state and much drier air filters in from the north. A rather pleasant weekend is then in store for South Texas with clearing skies and cooler temperatures persisting through the weekend. Highs Saturday and Sunday will range from the upper 60s to lower 70s, with lows in the 40s and 50s. A warming trend will follow early next week, with a return to a southerly flow, above normal temperatures and increased cloud cover.

Another upper trough is progged to move across the Rockies early next week, sending another cold front through the region late in the period. At this time, models have continued to disagree on progression of this next system, therefore, will maintain low end PoPs in the forecast Tuesday through Tuesday night.

MARINE...

Onshore flow will be strongest today over the open Gulf waters where SCA conditions will develop by midday and continue through early Thursday. Generally moderate onshore flow should prevail over the bays and nearshore waters today through tomorrow with some SCEC conditions at times. Isolated showers are possible through Thursday (mainly east of 96.5 degrees), before scattered showers and thunderstorms develop on Friday ahead of an advancing cold front. A moderate onshore flow Thursday night and early Friday will become moderate to strong offshore by Friday evening following the front. Rain chances will diminish on Saturday with drier air filtering in from the north. A light to moderate northerly flow will persist through the weekend. Onshore flow will resume Sunday night.
