What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 233 Am Edt Fri Jun 22 2018
Synopsis.. The region will be between high pressure to the south and troughing to the north through the weekend. Persistent westerly flow less than 15 knots keeps wave heights reduced today and overnight. The ridge begins to break down on Monday as a cold front approaches from the north. This front will cross area waters Monday night into Tuesday. High pressure will build to the north/northeast during the middle of next week.

Heat remains along with the chance of scattered showers and
thunderstorms...

Near term today and tonight ...

with convergent southwesterly flow across the northeastern gulf of
mexico, expecting showers and perhaps a few thunderstorms to be
ongoing along the coastal areas this morning. As the Sun rises,
instabilty begins to increase across the area with the potential
for a few showers and thunderstorms across the suwannee valley.

The evolution into the afternoon hours remains somewhat uncertain,
but early indications are that the overall coverage of
thunderstorms will be limited, especially for most of SE georgia.

With troughing to the north and the strong ridge remaining to the
south, forecast soundings show deep westerly flow from the surface
to 300 mb. This will keep showers and thunderstorms moving
eastward at 10-20 mph. The uncertainty for this afternoon
originates from the lack of widespread development by the
convective allowing forecast models. It would be expected that as
the showers and thunderstorms across western zones move eastward
during the afternoon, more instability would be available for
further development. Upper level ridge remains over the area so
the atmospheric column remains very warm with weak lapse rates
with height. Additionally, and perhaps one of the biggest factors
is the persistent and slightly stronger westerly flow that will
keep the east coast sea- breeze from moving inland. This prevents
an important boundary collision that has prompted widespread
activity the last couple of days across the i-95 corridor. Lastly,
forecast soundings show batches of dry air moving in from the
west, which will limit updrafts due to the entrainment of dry air.

With these factors in mind, decided to lean toward the lower
coverage overall today. The best chance for development will be
focused along surface boundary collisions along i-10 and
southward. Temperatures in the low to mid 90s, along with dewpoint
temperatures in the 70, once again push heat indices into the
100-106 degree range for several hours today. With westerly flow,
these conditions will be experienced at the beaches as well.

Tonight... Showers and thunderstorms diminish quickly with the
best chance for lingering activity across extreme southeast zones
where the sea-breeze could advance further inland with weaker
westerly flow. Plentiful low level moisture remains in place so
low temperatures persist in the mid to upper 70s overnight.

Short term Saturday-Sunday night
Lower pcpn chances are expected this weekend as sfc trof continues
over the SE us while sfc high pressure ridge remains to the south
of NE fl. This will keep a westerly steering flow across the
region and will keep the atlc coast sea breeze pinned near the
coast. This will also continue hot temps well into the lower to
middle 90s each day with heat indices around 105 degrees, likely
just below heat advisory criteria. On Saturday expect widely
scattered storms to break out in the afternoon as isolated
showers storms reach the pinned atlc coast sea breeze near the
coast and increase in coverage and intensity. High pressure aloft
and some drier airmass pushes in behind trof aloft into SE ga
limiting convection to less than 20% coverage on Sunday with hot
temps, while slightly weaker westerly flow on Sunday across NE fl
will allow for some sea breeze penetration from both coasts and
widely scattered storms during the afternoon hours with slower
movement than Saturday.

Long term Monday-Thursday
Higher pcpn chances are expected Monday through Wednesday as cold
front approaches from the north on Monday and crosses the region
on Tuesday and slowly washes out over the fl peninsula on
Wednesday. Moisture levels will increase as precip water amounts
(pwats) push back close to 2 inches or higher the cold frontal
passage. This will lead to at least numerous showers and storms in
this period. MAX temps still hot in the lower middle 90s on
Monday ahead of the frontal passage with heat indices still near
105 degrees, then closer to climo values around 90 degrees with
the frontal passage and development of onshore atlc flow on
Tuesday and Wednesday. Slightly drier airmass pushes into the
region following the front on Thursday with a return to more
normal scattered convection and temps back into the lower 90s
inland and atlc coast sea breeze pushing well inland in the
lingering onshore flow.

Aviation
Vfr conditions prevail early in the day as westerly southwesterly
flow dominates the area. Expecting showers and thunderstorms again
today, but with dry air present aloft, more scattered to isolated
coverage is expected. Only have vcts for NE florida TAF sites.

Sgj will observe an east-coast sea breeze during the afternoon,
but with westerly flow around 10 knots, expecting the boundary to
stick close to the coast. Showers and thunderstorms diminish after
sunset with light westerly flow andVFR conditions prevailing
overnight.

Marine
Synoptic pattern remains the same with surface high pressure to
the south and low pressure to the north, resulting in westerly to
southerly flow at less than 15 knots. With the offshore flow,
surf heights remain low along with the risk of rip currents. Dry
air aloft will reduce the overall coverage of showers and
thunderstorms today, but a slight chance remains for the waters.

Rip currents: low risk of rip currents at area beaches.
