Area Forecast Discussion
National Weather Service Miami FL
353 PM EDT Wed Aug 15 2018

Scattered showers and thunderstorms have developed across interior
and western areas of South Florida this afternoon. These showers
and thunderstorms will begin to diminish as this evening
progresses. Low temperatures tonight will range from the lower 70s
across the northwestern interior sections to near 80 across the
east coast metro areas. An area of high pressure over the western
Atlantic as well as South Florida will continue to dominate the
weather pattern throughout the rest of the week. This will help to
continue to keep a drier air mass in place as well which will
continue to help to limit the chances of showers and
thunderstorms. The areas with the greatest chance of having
convection will be across the interior and west coast areas during
the afternoon hours as the east and west coast sea breezes

High pressure will remain in place throughout the upcoming
weekend, however, the amount of low level moisture will begin to
increase as the drier air mass begins to depart and the wind flow
remains out of the southeast. This will allow for an increase in
chances of showers and thunderstorms during Saturday and Sunday
afternoon. The best chances of showers and thunderstorms will be
across the interior and west coast sections where the east and
west coast sea breezes collide. The latest computer model guidance
continues to show a typical summertime pattern continuing into
early next week as the flow will remain southeasterly. There will
be enough moisture to support shower and thunderstorm activity
along the east and west coast sea breezes during the late morning
and early afternoon hours.


Easterly to southeasterly flow will continue across the Atlantic
and Gulf coastal waters through the end of the week and into the
upcoming weekend as an area of high pressure remains in place.
Wind speeds will remain between 5 and 10 knots across the local
waters with seas of 2 feet or less throughout the forecast period.
Scattered showers and thunderstorms will remain possible
throughout the weekend. Winds and waves could be higher in and
around any shower or thunderstorm.


A Beach Hazards Statement remains due to the impacts of Florida
Red Tide along the Gulf beaches of northern Collier County. The
persistent easterly to southeasterly flow along the Atlantic
beaches will build the risk of rip currents over the next several
days heading into the weekend.
