Cold front could bring strong storms on Thursday...

Discussion
Today is likely the final day of relatively quiet weather before
a more unsettled pattern begins over most of south florida. A
persistent southeasterly flow will combine with atlantic moisture
to produce some chances for light rain showers over the atlantic
waters and along the east coast today. Rain chances are expected
to increase as the front moves closer to the region tonight. The
parent surface low will be centered north of the great lakes in
canada with a mid-level trough extending south, along with the
surface front, into the gulf of mexico.

Not only are showers expected with this front, so are
thunderstorms. There is a possibility that the atmospheric
environment could support some stronger storms. The main storm
modes would be discrete cells well ahead of the front and a
quasi-linear convective system or squall line closer to the
frontal boundary. One factor raising some concern for stronger
storms are 0-1 km helicity values well in excess of 150 m2 s2.

The focus of the wind shear is highest over northern portions of
the forecast area around lake okeechobee. This will have to be
monitored as a strong to severe storm threat could emerge for late
tonight into Thursday with this system. The primary concerns would
be with strong to damaging winds and the potential for tornadic
activity.

As we enter Friday, the front will stall south and east of the
forecast area. This will allow some drier, cooler air to settle
over the region for a brief period of time. Unsettled weather
returns for Sunday as some surface tropical moisture from the
gulf of mexico and caribbean combines with a mid-level shortwave
trough to allow showers and thunderstorms to return to the
forecast Sunday into Monday. There is some divergence between
guidance on possible solutions in this time period. All seem to
have focused on a more southerly track over south florida and the
florida straits for the moisture. Some solutions are also
resolving a surface low developing (or an elongated trough) which
could raise thunderstorm chances for Monday. Once again, the
progress of this portion of the forecast will also have to be
monitored for strong storm potential in case the surface low were
to develop more vigorously than currently forecast.

As this disturbance moves out Tuesday, a reinforcing cold front
will make its way through the region. It could be a drier frontal
passage compared to the one earlier in the forecast though
additional moisture could be knocking on the door from the gulf
if the front stalls north of the region. Uncertainty this far out
in the forecast period is still high as minor changes to the
synoptic pattern could mean the difference between dry, cold air
over the region or warm, moist air. The potential for some very
cold air invading part of the state does exist in this portion of
the extended, but it is way too early to discern just how
impactful any cold air intrusion could be for south florida. Kept
a middle of the road philosophy for temperatures through the
period with a preference around the mean of the models.

Marine
A persistent southeasterly flow will continue through the day with
advisory conditions continuing over the atlantic waters. The wind
should begin to diminish over the gulf waters and lake okeechobee
this morning, allowing conditions to slowly improve. As the front
moves across the region on Thursday, increasing shower and
thunderstorm activity is expected. A brief dry period to kick off
the weekend will eventually give way to the next disturbance late
in the weekend into early next week.

Beach forecast
A high risk of rip currents will remain along the atlantic beaches
into Thursday thanks to a persistent southeasterly flow today that
will shift as the front pushes across the region tomorrow. Behind
the frontal passage, some of the gulf beaches could see a brief
elevated risk of rip currents on Friday.

a tight pressure gradient across the area continues to bring
breezy conditions to south florida. This will continue until a
cold front moves through on Thursday. There are a few -shra along
the atlantic coast, but on sprinkles for the most part, so left
out of the tafs for now. Chances of rain should increase sometime
tomorrow night as the front begins to approach the area. A few ts
are also possible by Thursday morning.
