DISCUSSION...
SHORT TERM (Today through Sunday)

Stalling cold front is draped over South Florida early this
morning, and at this point is becoming more and more difficult to
analyze. This feature will continue to influence weather today,
inducing isolated to scattered showers and thunderstorms this
afternoon over southeastern portions of the region, before
dissipating tonight. A few showers have persisted over southern
Atlantic waters overnight and this may continue through much of
the day. With light, slightly convergence low-level flow,
waterspouts are possible with this activity.

After today, deep layer high pressure will build overnight,
producing a weekend of mostly sunny skies and above normal
temperatures. Cant rule out an isolated interior thunderstorm over
the Everglades Saturday afternoon, but aside from near-surface
moisture, relatively dry air will dominate. Maxima will range
from upper 80s along the coast to mid 90s interior and heat
indices will be around 100 degrees. Winds will be sea-breeze
dominant.

LONG TERM (Sunday night through Thursday)
For Memorial Day and Tuesday more of the same weather is expected
with deep-layer ridging in place, so expect above normal
temperatures and generally dry conditions to prevail. The high
pressure will gradually weaken and slight eastward as the week
progresses, bringing more dominant southeasterly winds, increasing
moisture, and gradually increasing shower and thunderstorm
chances.

MARINE...
A cold front has remained over the waters overnight and will stall
over the region today. This will lead to a few showers and
thunderstorms over the Atlantic, and waterspouts are possible due.
Locally higher winds and seas are also possible in and near any
convection. After today, dry conditions will prevail through the
holiday weekend. Wind direction will be northerly today, variable
Saturday, then generally southerly for the bulk of next week.
Speeds will be under 15 kt and seas will be 4 feet or less.

FIRE WEATHER...
Relative humidity values over Hendry and Glades counties will drop
to under 40 percent each afternoon today through Memorial Day
weekend.  However, winds are expected to be under 10 mph.
