early this morning will shift to N-NE after 15z and increase to 15
knots with gusts to near 25 knots. Winds become NE/E after 00z,
staying rather high with gusts at or over 20 knots especially at
the east coast sites. Gusts may start to subside after sunrise on
Wednesday.

.PREV DISCUSSION... (Issued 333 AM EDT Tue Apr 19 2022)
SHORT TERM...
Today through Wednesday...
Quiet conditions are in place across South Florida early this
morning as a cold front over Central Florida moves towards our
area. Dew points remain rather high this morning, however with
the eventual passage of the frontal boundary later today, drier
air will begin to filter into the region in earnest. Large high
pressure will build into the SE United States behind the departing
upper level trough over the Atlantic, which will act to create
widespread subsidence over the area. Therefore, a mainly dry and
breezy day is expected across the area with abundant sunshine most
areas. A few showers are possible this afternoon over far
southern areas of the peninsula primarily in the Cape
Sable/Flamingo area and far southern Everglades where the notably
drier air will not arrive until this evening. A thunderstorm isn't
out of the question in this area. Not a lot in the way of cooling
today as the cold air advection is rather weak and lagging behind
the front. Highs in the mid to upper 80s are expected today,
possibly touching 90 in the Naples area.
The high pressure will persist through Wednesday and allow for a
continued respite from stormy weather. The cooler air will be
more noticeable tonight and lows are forecast to drop into the
upper 50s over inland SW Florida, and 60s elsewhere except near 70
along the Atlantic coast. Highs on Wednesday will likely stay in
the upper 70s along the east coast in a fresh NE to E breeze, with
80s over the interior...warmer as you go west and lose the
moderating influence of the Atlantic.
LONG TERM...
Wednesday Night through Monday...
Synoptic subsidence due to the aforementioned ridge of high pressure
will continue to suppress precipitation chances through the beginning
of the extended period. With the gradual progression of the surface
high into the western Atlantic waters, the surface wind flow will
shift in response. Thus the prevailing wind flow across South Florida
will begin to shift out of the east late this week. Easterly flow will
act to support moisture transport in the boundary layer and the
easterly fetch will transport a deeper pocket of moisture into the
region. Initially, considerable amounts of residual dry air in the
vertical column should keep convection shallow in nature which will
support showers as the primary mode of convection. However, while
most of the activity will remain shallow and supportive of mainly
showers, there will be just enough instability by this weekend to
support a slight chance of thunderstorms along the sea breezes as
they move inland. Temperatures will remain seasonable across the
area for the foreseeable future, with lows in the 60s and lower
70s and highs in the 80s.
MARINE...
Drier air will continue to filter into the region through mid-week as a
ridge of high pressure builds into the region. A developing tight pressure
gradient between high pressure over the eastern U.S. and low pressure
over the eastern Bahamas and central Caribbean will allow for winds
to increase and seas to build today, with seas as high as 8 feet
in the Atlantic Gulf Stream this afternoon through at least
Wednesday night, with seas to 6 feet in the outer Gulf of Mexico
waters. A Small Craft Advisory will be in effect starting at 12z
today for the Gulf and Atlantic waters due to increased seas and
winds. Hazardous marine conditions will continue for much of the
week as breezy winds will prevail over area waters.
FIRE WEATHER...
Dry and breezy conditions are expected today behind the passage of a
cold front early this morning. Breezy northwesterly to northerly
winds will prevail across the area today with relative humidity
values approaching critical thresholds across the western interior
of South Florida. Winds will likely stay below critical values,
however enhanced fire weather conditions are likely today over
much of inland SW Florida. Dispersion values today will range
from the good range across the east coast metro and Gulf coast
with dispersion values in the very good range across the inland
areas of South Florida. Winds will gradually shift to a NE
direction by mid-week with good to very good dispersion values
possible each afternoon.
BEACHES...
Increasing easterly winds through the week will allow the rip current
risk to increase along the Atlantic beaches with many beaches
potentially seeing a high risk as early as this afternoon. This
will likely linger into late week if not the weekend.
