area forecast discussion

253 am edt Sat aug 24 2019

Discussion
The main story for the weekend is the area of low pressure sitting
over south florida. While it is tropical in nature, no significant
development is forecast while the low is over the area. Models
show the low meandering around the area for the next 24 to 36
hours, bringing increased chances for showers and thunderstorms.

However, given the tropical nature, and 500mb temperatures around
-5.5c to -6c, would expect the lightning to be fairly limited
today in count, but still possible. The GFS is showing plenty of
surface based CAPE today, with values ranging from around 900
j kg to well over 2000 j kg, varying spatially and temporally.

The GFS is showing the pwats to exceed 2 inches, and may be near
2.5 inches at times. This would bring heavy rain to the area,
which may also bring some localized flooding, mainly in the urban
areas where streets may flood due to poor drainage and in low
laying areas.

The low should begin to move off to the northeast sometime on
Sunday, and could possibly develop into a tropical system once it
leaves the area and the center returns to the marine environment.

However, both the GFS and the ECMWF are hinting at the system
perhaps being a hybrid, with a training cold front behind it. This
is seen in the surface wind fields, with a wind shift along a
boundary from the gulf waters, through the ft myers area, to the
western edge of lake okeechobee, and northeast through the vero
beach area. This boundary may act as a focus for some convection
on Sunday, especially in the lake region. By Sunday night,
the boundary become diffuse and the wind becomes more uniform out
of the southwest.

As the system departs the area, the GFS and the ECMWF diverge as
to what type of weather to expect. The ECMWF keeps showers and
storms over the area, even with a surface high building, as well
as a 500mb ridge. The GFS has similar features, but is drier for
the beginning of the week, with what appears to be a dry slot
behind the developing system. For now, kept Monday afternoon as
fairly active with showers and thunderstorms, and backed off on
pops for Tuesday, but still have a chance of convection, mainly in
the afternoon.

By the middle of the week, the models show a 500mb trough digging
into the southeast us, with the main low pressure system well to
the north, over the hudson bay. Both the GFS and ECMWF show a very
long cold front moving into north florida during the latter half
of the week, helping to bring additional instability to the area,
as well as keeping moisture in place. Both models are also hinting
that another surface low may develop over the region, along the
stalled frontal boundary. This would help to enhance convective
activity for Thursday and Friday. For now, kept pops in the chance
range.

Temperature wise, the models are coming in with seasonable temps
through the forecast period, with highs around 90 and lows in the
mid to upper 70s.

Marine
A low pressure system, sitting over south florida, will keep the
winds generally out of the south for the atlantic waters, and
northerly for the gulf today. As the system begins to exit the
area on Sunday, the wind should eventually become more uniform out
of the southwest across the area. The low will keep chances for
showers and thunderstorms over all south florida waters through
the weekend, and into the beginning of the week. Some of the
showers and storms may bring locally rough marine conditions as
well as a moderate risk for waterspouts this weekend, and possibly
Monday.

Otherwise, seas are forecast to be generally one to two feet
through the forecast period, with seas increasing to around three
feet in the offshore atlantic periodically through the week.

Aviation
Tropical disturbance is producing periods of showers moving
onshore from the atlantic with vcsh at all terminals. Shra that
do move over the terminals may bring brief MVFR ifr vis and cigs,
handled with amendments. Winds will be southerly, except kapf
where gulf breeze will develop in afternoon, around 10 knots today
with showers and storms in the vicinity throughout the day. Winds
will be come S SW overnight with showers remaining in the taf.
