945 pm edt Wed may 24 2017

Update Main convective line has pushed off the east coast late
this evening, and the severe thunderstorm watch has been cancelled
for all of south florida. Still expecting a lull in significant
activity most of the overnight, with some showers and the
potential for a storm or two at best. Rain chances look to
increase as the main front drops south towards daybreak, but
currently the threat for additional strong-severe storms looks
low.

The forecast has been updated to reflect the current forecast
trends.

Prev discussion issued 824 pm edt Wed may 24 2017
update... Main pre-frontal squall line accelerated this afternoon
and now is currently moving across the east coast metro. Several
strong to severe storms continue along this line, with the
potential for additional gusts to around 60 mph possible with any
activity, along with frequent lightning and locally heavy rain.

Environment has also become a little more favorable for rotating
storms.

The line is expected to exit the east coast within the next 1-2
hours, with scattered showers and isolated storms behind it. Radar
and satellite trends suggest a lull in activity most of the
overnight, with a few showers at best, with potential for
additional storms as the front drops south towards daybreak.

Prev discussion... Issued 725 pm edt Wed may 24 2017
aviation... Widespread showers and storms ongoing across region
currently. Main squall line is now east of kapf, will push through
east coast sites 00z-02z. Tempo ifr vsbys MVFR CIGS along with gusts
40-45kts possible within any convection. Lull in activity expected
03z-12z as main line moves into atlantic, with vcsh for all sites.

Increase in convection after daybreak as main front approaches,
with vcts for all sites along with a return of gusty SW winds
15-20ktsg25kts.

Prev discussion... Issued 355 pm edt Wed may 24 2017
discussion...

this afternoon and tonight... The main concern for the remainder of
today and tonight continues to be for strong to severe storms across
all of south florida. Outside of any convective development, it will
remain a hot and breezy day with temperatures currently peaking in
the low-mid 90s and southwest winds gusting to near 30 mph.

A warm, moist and unstable atmosphere is in place across south
florida this afternoon with a few showers and storms already
developing across the region. Southwesterly flow is picking up to 30-
40kts between 4-9kft, with 0-1km helicities a respectable 100
m2 s2. Further north, severe weather is already ongoing across
central and north florida with widespread activity.

Severe storm potential looks to come in two phases. The first
will be this afternoon primarily along the east coast, where the
seabreeze has developed and pushed inland across miami-dade,
broward and a portion of the palm beach barrier island. Scattered
showers and storms will continue to develop across the region for
the remainder of the afternoon, focusing along the palm beach and
broward metro early evening. With a few models showing low level
helicities increasing to 200-300 m2 s2, along with the low level
jet picking up, the concern remains for strong wind gusts and
isolated tornadoes. Given the instability in place, hail also will
be a concern especially with storm collisions.

Second wave will be this evening through overnight across all of
the region as the pre-frontal squall line over the eastern gulf
and west florida approaches the region. Models have sped up the
timing of this line considerably, which is consistent with current
radar trends. The line may weaken as it approaches and moves
further away from its parent front system, but earlier arrival may
mean more daytime instability is available. Convective activity
looks to continue through the overnight primarily north of a
everglades city to boca raton line. The main threat with overnight
activity will be for strong winds, but isolated tornadoes may
remain a concern with boundary collisions.

Localized heavy downpours can not be ruled out with any activity,
but due to the ongoing dry conditions and quick storm movement, no
significant flooding is expected.

Thursday... Showers and storms will continue through the day on
Thursday as the front slowly moves through the area. The best
dynamics will be lifting off to the northeast with the main upper
level trough, though low level winds will continue around 40kts. The
threat for significant severe weather will rapidly diminish during
the morning hours, though a few gusty storms will remain possible.

Activity will diminish from NW to SE into the afternoon as the
front pushes further south.

Extended memorial day weekend... Frontal boundary will wash out
across the far southern peninsula by Friday, with the deeper
moisture finally shunted south of the region into Saturday behind a
secondary weak mid level trough passage. High pressure will build in
both at the surface and aloft, leading to a more suppressed
atmosphere and light winds. A typical south florida summertime
pattern will be in place with the seabreezes developing and moving
inland each afternoon. A few showers and storms will likely develop
along the sea breeze as it moves in, with the best coverage in the
afternoons and early evening with the seabreeze collision over the
interior. Temperatures will be near to slightly above normal in the
upper 80s and low 90s.

Next week... Surface high will move east into the western atlantic
early next week, with low level flow becoming more easterly across
the region. While both seabreezes will still be able to develop and
move inland, the east coast seabreeze will be more dominant, with
the best afternoon shower storm chances over the interior and gulf
coast and the east coast likely staying dry.

Marine... Strong and gusty south-southwesterly winds will continue
into early Thursday ahead of the cold front currently moving through
the florida peninsula. Speeds will continue around 20kts, with gusts
up to 30 knots possible outside of any convection. Seas look to peak
around 6-7ft in the offshore gulf overnight with similar heights in
the gulf stream by early Thursday. A small craft advisory remain in
effect for all of the local waters.

Numerous showers and storms are expected from late this afternoon
into this evening as the front pushes further south, with the
potential for a few strong to severe storms. Frequent lightning,
gusts over 50kts, and isolated waterspouts may accompany the
strongest storms.

The front will wash out across the region late Thursday, with winds
becoming west-southwest around 15 knots. Winds will become light and
variable into the upcoming memorial day weekend, with the afternoon
seabreezes developing each afternoon. Winds may reach 10-15kts with
the seabreezes near the coast during the afternoon. Seas diminish to
2ft or less by Saturday. A few storms may affect the intracoastal in
the early afternoon, with the best chances generally over interior
waterways and lake okeechobee in the afternoons.

Climate... The east coast metro areas will be getting close to the
record highs for today which are:
