Damaging Wind in Florida, June 5, 2018

Area Forecast Discussion
National Weather Service Miami FL
341 PM EDT Tue Jun 5 2018

.DISCUSSION...
Scattered showers and thunderstorms have developed this afternoon
especially across Palm Beach County as a weak frontal boundary
moves closer to South Florida. Any additional shower or
thunderstorm develop will begin to diminish as this evening
progresses. Low temperatures tonight will range from the lower 70s
across the interior sections to the upper 70s across the east
coast metro areas.

A shortwave trough will approach the Florida peninsula by the
middle of the week. this will help the surface cold front move
closer to the Lake Okeechobee region where it will stall out and
eventually diminish. This frontal boundary however will bring
higher rain chances to the area as deeper moisture moves into
South Florida. The greatest amount of coverage will be across the
Lake Okeechobee area as well as interior sections near the
frontal boundary before shifting towards the east coast metro
areas later in the day. Westerly flow will remain in place during
the middle of the week before shifting to a southeasterly flow by
the end of the week.

Scattered to numerous showers and thunderstorms will continue into
the upcoming weekend across the region. The greatest coverage will
be across interior sections as the east and west coast sea breezes
develop and collide as they move inland. Relatively lower midlevel
heights and cooler temperatures aloft will remain in place into
the weekend as the trough gradually weakens across the state. With
these cooler temperatures aloft, it may allow for a few stronger
thunderstorms to develop. Temperatures will be near normal in the
mid to upper 80s during the day and low to mid 70s at night.

&&

.MARINE...
A ridge of high pressure will remain in place across the western
Atlantic south of the Florida Peninsula as a weak front continues
to move slowly southward. West to southwest winds of 10 to 15
knots are expected in the Atlantic and Gulf Waters through the
middle of the week. The front will dissipate by the end of the
week which will allow the winds to shift to the southeast at 10
knots or less during the weekend. Seas generally 2 feet or less,
occasionally 3 feet in the Atlantic. Storms moving offshore into
the Atlantic will be a concern through Thursday during the
afternoons and evenings.

&&

.AVIATION...
Showers are developing to the west of KPBI early this afternoon,
and scattered activity, possibly thunderstorms, should impact the
vicinity of all east coast terminals. Transitioned to VCTS all
eastern sites except KTMB, where POPs are lowest. West wind around
10 KT prevails through early evening, although Atlantic seabreeze
may briefly transition KFLL and possibly KOPF/KMIA to SSE. Light
west wind overnight, then increasing to 10 KT again by mid-morning
Wednesday. More showers are possible Wednesday afternoon. Away
from convection, VFR conditions should prevail, although
occasional late night/morning MVFR CIGs could impact KAPF.
