GMZ600 Synopsis For Pascagoula Ms To Okaloosa Walton County Line Fl Out 60 Nm Including Major Area Bays And Sounds- 934 Pm Cst Sat Dec 7 2019
Synopsis..Light to moderate easterly flow will become more southeasterly Sunday ahead of an approaching cold front. The cold front moves through the area Tuesday with an increasingly strong offshore flow developing in its wake. A small craft advisory will likely be required for portions of the marine area, especially over the gulf waters, by Tuesday night continuing through at least Wednesday night.

Area Forecast Discussion National Weather Service Miami FL 135 AM EST Sun Dec 8 2019
Aviation. VFR expected to prevail during the next 24 hours at all terminals. Light and variable winds will turn generally ENE after 14-15Z at 8-10kt except APF where sea breeze circulations will veer winds to the WSW around 8kt in the afternoon.
Prev Discussion. /issued 1027 PM EST Sat Dec 7 2019/
Update . Weak quasi stationary front just north of the CWA and associated cloudiness/moisture have resulted in increasing cloud cover particularly across the northern sections of the CWA. This should inhibit chances of fog formation inland despite light winds. Flow should remain light and variable overnight for the most part across the CWA as pressure gradient remains weak due to proximity of the boundary. Updated forecast to better reflect current wind trends and cloudiness overall. Other than that, no other changes were made. We currently have mention of sprinkles overnight across portions of Palm Beach but confidence remains very low that will materialize. Regardless no impact weather associated with that. But left it in forecast due to proximity of aforementioned boundary.
Prev Discussion . /issued 648 PM EST Sat Dec 7 2019/
Aviation . Generally VFR conditions are expected through Sunday, with light ene winds overnight turning more easterly 4-8 kts by late morning or early afternoon on Sunday at east coast sites and more southerly about same speed at APF. A few sprinkles with some ceilings particularly at PBI cannot be ruled out by sunday morning but they are expected to remain in VFR range. Confidence is very low in any (if any) related impacts at the TAF sites.

Short Term .
Tonight through Sunday night .
Visible satellite loops indicate a well-defined cumulus-cloud line -- delineating an axis of convergence -- trailing south of a weak frontal wave located about 100 miles east of the east-central FL coast. The very modest theta-e contrast across this boundary highlights its characteristically weak baroclinicity, and this feature will undergo additional frontolysis through tonight.
The continued eastward elongation of surface ridging off the Mid- Atlantic coast -- beneath of a zone of broad differential anticyclonic vorticity advection aloft -- will correspond to low- level flow turning more easterly across the aforementioned boundary tonight. This will allow the boundary to edge toward the South Florida coast while becoming even more diffuse through late tonight. The combination of (1) subtle boundary-related ascent, (2) frictional convergence along the Atlantic coast associated with the increasing east-wind component, and (3) meager isentropic ascent, could support a few sprinkles late tonight into Sunday morning. Such activity should principally be confined to coastal and metro Palm Beach and perhaps Broward Counties, where the coastline shape maximizes the frictional convergence. The shallow/marginal nature of upward motion, and limited supply of moisture, preclude confidence in measurable precipitation.
Elsewhere, dry conditions are expected tonight, with low temperatures forecast to range from the middle 50s across western sections of interior South Florida to the 60s elsewhere. Nocturnal decoupling could yield a non-zero fog risk, especially over interior sections. However, the potential for clouds emanating from a persistent area of predominantly shallow convection over the eastern/middle Gulf could mute nocturnal radiational cooling -- limiting confidence in fog development.
Then for Sunday, diurnally increasing vertical mixing over inland areas will encourage the suppression of east-coast-vicinity convergence, while low-level flow becomes predominantly easterly across the forecast area -- resulting in cessation of the potential for sprinkles by mid/late morning. With generally partly cloudy skies expected through the day, high temperatures on Sunday are forecast to be around to a degree or two above those of today/Saturday -- i.e., in the upper 70s to lower 80s on Sunday. Then for Sunday night, decreasing winds will accompany nocturnal decoupling amid a weak surface pressure gradient, with overnight low temperatures forecast to mostly be in the 60s. While fog cannot be ruled out, the potential for clouds, and the lack of more appreciable moisture return into an antecedently cool air mass, render limited predictability in the potential for fog.
Long Term .
Monday through Friday .
High pressure will remain in control of the weather across South Florida during the early portion of the week. A southeasterly wind flow will continue during this time frame as well. This will allow for warm pattern across the region as afternoon high temperatures will range from the lower 80s across across the east coast metro areas to the mid to upper 80s across the southwestern interior sections.
As the middle of the week approaches, both of the GFS and the ECMWF continue to show a mid level trough pushing across the eastern portion of the country. An area of low pressure in the northern Atlantic will have a cold front dragging south southwestward along with it. The latest computer model guidance shows this front getting into Northern Florida by Wednesday and then moving southeastward on Thursday. Winds during this time frame will remain out of the east southeast which will help to bring more moisture into the region as well. Chances of showers will start to increase beginning on Wednesday. An area of high pressure will be building into the Mid-Atlantic on Thursday, which will allow for an east northeast wind flow across South Florida along with an increase in speed moving into Thursday. With the breezy easterly flow in place, this will allow for the chance of showers remaining across the region through the end of the week.
Marine .
North winds will continue to turn more easterly and occasionally become breezy through the weekend over the South Florida waters. Seas will mainly be 2 feet or less, with only isolated sprinkles possible over the Palm Beach and Broward County coastal waters for late tonight into Sunday morning. During early to middle parts of next week, the approach of a weather system from the west will correspond to a gradual increase in east to southeast winds. By the middle of next week, deteriorating marine conditions could materialize as winds and waves increase, while shower activity also has the potential to increase.
Aviation .
Generally VFR conditions are expected through Sunday, with light winds gradually turning from primarily northerly to easterly. A few sprinkles cannot be ruled out in the vicinity of coastal Palm Beach and Broward Counties late tonight into Sunday morning, though confidence is very low in any related impacts at the TAF sites.
Beach Forecast .
Aside from the potential for a few sprinkles over the Palm Beach and Broward County beaches late tonight into Sunday morning, dry conditions are expected through the remainder of this weekend. For early to middle parts of next week, increasing onshore flow could foster an increasing elevated rip-current risk. Shower chances will also increase during the mid-week time frame.
