SHORT TERM (Today - Wednesday)...

Strong high pressure aloft remains centered over the northern half
of the peninsula, while the associated sfc ridge expands into
SoFlo. These features will keep mainly moderate easterly winds
across the area through the next couple of days. Rain chances will
be limited as subsidence, drier air and warmer will prevail. This
will result in having a much more stable airmass, with plenty of
sunshine and no significant mechanism for lifting. Any shower that
forms should be short-lived and fast-moving.

Maximum temperatures are forecast to be slightly warmer than
normals, with most areas experiencing highs in the mid/upper 80s
over the eastern counties and interior respectively. The western
counties and Gulf coast could see maximum temperatures in the lower
90s.

LONG TERM...

Thursday through Sunday...

The remnants of Tropical Cyclone Zeta will merge with a shortwave
trough as it digs aggressively into the Gulf Coast States later
this week. Thereafter the upper wave lifts towards New England and
the Canadian Maritimes. A deepening surface cyclone will
accompany the upper wave, as the attendant cold front drops
towards the Lake Okeechobee region by Friday. Current forecast
solutions have the front clearing South Florida over the weekend,
while becoming stationary in the vicinity of the Florida Straits
or Cuba. Given the somewhat weak nature of the front, the primary
impact ahead of it should be showers and perhaps a few
thunderstorms. Thereafter, quick-moving showers remain possible
through the remainder of the weekend within a breezy northeasterly
flow regime.

Monday and Tuesday...

A meridional flow pattern should prevail aloft featuring sharp
eastern troughing and upstream ridging across the central States. A
reinforcing cold front should reach our area during this period, as
strong low-level ridging prevails across the Southern Mississippi
Valley. The front is forecast to clear South Florida by Tuesday,
bringing much lower humidity and largely confining shower chances to
the local waters.

MARINE...

Winds remain moderate from the east-southeast with high pressure
aloft dominating the region. The NE swell affecting the
nearshore/offshore Palm Beach waters will gradually subside, and
should be non-existent by mid/late-week. A cold front may approach
South Florida by early next week and could increase seas/swell
during this period, however it is too early to determine exact
impacts (if any).

BEACHES...

A high risk of rip currents remains in effect for
the Atlantic beaches through today due to the moderate onshore
(easterly) wind and NE swell. The risk will likely stay elevated
through Wednesday before finally diminishing towards the end the
week.
