Update
No changes needed to be made to the previous forecast as
everything looks on track. An area of high pressure will continue
to slide off to the east tonight and it will shift the winds
around to a more east to southeasterly direction during the
overnight hours. Low temperatures tonight will not be as cool as
they have been in recent nights as they will drop down into the
lower 50s across the interior sections to the mid 60s across the
east coast metro areas. Lower level moisture will begin to
increase on Wednesday and the chances of showers and isolated
thunderstorms will increase later in the day and then again on
Wednesday night as a warm front approaches the region from the
south.

the forecast period.

discussion...

an area of high pressure will continue to dominate the weather
pattern across south florida for tonight as it continues to slide
off to the east. Winds will continue to shift to a more east to
southeasterly direction as the night progresses. This will allow
for temperatures tonight to be not as cool as they have been over
the previous two nights. Low temperatures tonight will drop into
the lower 50s across the northwestern interior sections to the mid
60s across the east coast metro areas.

As far as Wednesday and Thursday are concerned, the latest model
guidance continues to show a stormy and unsettled weather pattern
taking place as a major system develops across the southeastern
portion of the country. The southern upper level shortwave
currently over the southwestern portion of the country will phase
with a northern shortwave which will form a deep trough as it
moves into the eastern portion of the us. This will also allow for
a strong upper level low to form across the northern gulf coast
which will lead to a strong surface low lifting across the
southeast during the middle to latter portion of the week.

Low level moisture will begin to increase later on Wednesday and
on Wednesday night as the previous frontal boundary will begin to
move northward as a warm front. This will help to increase the
instability across the region as dewpoints will climb back into
the upper 60s and lower 70s. The chances of showers and an
isolated thunderstorm will increase later on Wednesday and
Wednesday night especially during the overnight hours. The initial
northward movement of the boundary may also bring a more favorable
environment for isolated tornado development as we see a
strengthening low level wind field and increasing low level
helicities for most of south florida on Wednesday night.

The latest computer model guidance shows most of the activity
occurring across the region on Thursday and Thursday night. The
upper level low is expected to continue to dig southward across
the gulf through the day on Thursday before starting to lift
northwards on Friday morning. This will allow for the best
dynamics to phase with the best instability farther south. This
is something that has been different with the past two fronts
where the best dynamics and instability have remained farther to
the north. Model consistency continues to be good in showing the
low level wind field strengthening to 40 to 55 kts, suggesting the
threat for damaging winds along with an isolated tornado concern
on Thursday afternoon and Thursday night as what will likely be a
strong pre frontal squall line moving through the area. The latest
computer model guidance continues to lean towards the best rain
chances being towards the later portion of the afternoon and into
the overnight period. Currently all of south florida is in a
slight risk for severe weather for Thursday.

Heavy rainfall will also be a concern, with rainfall amounts
potentially in excess of two inches on Thursday, highest along
the gulf coast. Most of south florida, excluding the atlantic
metro areas, is currently under a marginal risk for flash flooding
during this timeframe. Any heavy rain will be aggravated by
higher water levels, with the potential for at least minor
extratropical surge along the gulf coast Thursday and Friday.

Ahead of any squall line, it will be a very windy day, with the
potential for wind advisory criteria to be met across the region.

The main frontal boundary looks like it will pass through south
florida on Friday. The instability will be limited during this
time frame, however, with the strong winds still remaining in
place, showers still cannot be ruled out throughout much of the
day. High pressure will then build in for the upcoming weekend and
bring a cooler and drier air mass along with it. Highs may struggle
to get into the 70s for the weekend, with chilly overnight lows
in the 40s and 50s.

Marine...

high pressure will continue to dominate the weather pattern across
the atlantic and gulf waters as it continues to slide off to the
east tonight. Winds will then begin to shift around to the
southeast on Wednesday. A warm front will move through the region
Wednesday night which will increase the chances of showers and
thunderstorms and increase the winds as well. A strong system moving
through the southeastern portion of the country Thursday and
Friday will bring hazardous boating conditions both days, likely
lingering into the upcoming weekend. There will be the potential
for gale force winds during the timeframe across all the local
waters, with seas reaching in excess of 15 feet in the offshore
gulf and 9 to 12ft in the offshore atlantic.
