Gulf Stream Hazards: None.

.Aviation... Generally VFR through the period though some lower cigs are possible coming off the Atlantic around the east coast terminals. Otherwise, easterly flow will continue except at APF where a Gulf sea breeze is expected to develop. Atlantic showers cannot be ruled out but chances are too low to mention.
.Prev /issued 346am EST Fri Nov 22 2019/
Today through Saturday... Easterly flow will continue today as a surface area of high pressure remains centered over the Carolina coast. At the mid to upper levels, high pressure extends over the region from the southern Gulf of Mexico. This setup should allow the relatively dry pattern to continue today, with only an isolated Atlantic shower possible. Cloud cover will be greatest over eastern portions of the area, closer to the Atlantic waters. The Gulf sea breeze is expected to develop today and push inland of the Gulf coast towards the Interstate 75 corridor with limited convection mainly isolated to some additional cloud cover. Temperatures will continue to gradually warm with most areas reaching into the lower to mid 80s today.
The next cold front approaches the southeastern United States with the surface high pressure sliding southeastward. This will keep an easterly flow over the region, though it may eventually pick up a southerly component. Temperatures will once again creep up a few degrees on Saturday for both minimum morning and maximum afternoon temperatures. Cannot rule out some isolated showers focused over the moisture provided by the Atlantic waters.
Long Term... Saturday Night through Thursday... Models continue to indicate a low pressure system tracking over the TN valley region and towards the NE CONUS Saturday night into Sunday with an associated cold front stretching southward into the Gulf. With the previous high pressure finally off to the east, winds will veer from the south/southeast before veering from the southwest overnight, advecting in modest amounts of moisture across the region. Highest PW's are forecast to be along the Gulf waters, therefore highest Probability of Precipitation Saturday night into early Sunday morning should stay offshore, especially due to lack of instability (a fairly decent cap is noted in the 700 mb to 600 mb layer of forecast soundings) and fairly dry air in the mid-upper levels.
By Sunday afternoon, the cap is forecast to erode, which makes sense due to daytime heating and also the front draped over South Florida. Both the GFS and ECMWF (European Centre for Medium-Range Weather Forecasts) continue to show a mostly dry frontal passage with a slight chance of showers across land and a scattered chance for showers across the local waters. No thunderstorms are anticipated with this front as the dynamics and forcing are displaced well to the NE of the boundary. This front is forecast to move into the area Sunday afternoon and exit early Monday morning.
Behind the front, high pressure builds and keeps the area dry through the remainder of the week. The air mass behind the front will not bring a significant temperature change, though it will advect a drier air mass into the area with dewpoints in the 50s Monday morning. A gradual warming and moistening trend takes place through the middle of the week. Then, by the very end of the forecast period, a backdoor front approaches FL.
Marine... High pressure will permit generally benign conditions over the local waters. The next cold front enters the picture this weekend with the potential for increasing chances of showers and thunderstorms.
Beach Forecast... An easterly wind flow regime persists, allowing for a reinforcement of the elevated rip current risk into the
