AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 324 Am Edt Wed May 22 2019
Synopsis.. Strong high pressure extending from eastern canada across the eastern portion of the great lakes will build down the southeastern u.s. SEaboard today, resulting in a surge of easterly winds over our waters this afternoon. Breezy onshore winds will prevail through Thursday before high pressure builds directly over our waters by late Thursday night and Friday, resulting in decreasing winds and seas. High pressure will then sink southward over the florida peninsula this weekend, with light offshore winds each morning shifting to onshore in the near shore waters with the sea breeze development each afternoon, followed by evening southerly wind surges this weekend through early next week.
Gulf stream.. The approximate location of the west wall of the gulf stream as of may 21, 2019 at 1200 utc... 62 nautical miles east of flagler beach. 70 nautical miles east of saint augustine beach. 82 nautical miles east of jacksonville beach. 96 nautical miles east southeast of st simons island.

Breezy onshore winds develop at coastal locations this
afternoon...

Record heat and dry weather this memorial day weekend...

Currently
Overnight surface analysis depicts strengthening high pressure
(1024 millibars) extending from southern portions of hudson bay
southward through the mid-atlantic states. Aloft... Ridging is
building directly over our region as deep troughing prevails over
the western u.S. The collision of the atlantic and gulf coast sea
breezes produced shallow convection along the i-75 corridor in
alachua county on Tuesday evening, and leftover mid-level debris
clouds are drifting over the suwannee valley, with isolated light
showers along and just west of the suwannee river in lafayette
county. The evening soundings at jacksonville and tallahassee both
displayed stout subsidence inversions around 700 millibars
(10,000 feet), and moisture trapped just below this inversion is
also resulting in some predawn altocumulus along the i-95 and u.S.

Highway 301 corridors in southeast georgia, extending southward
into the metro jacksonville area per goes-east nighttime
infrared fog satellite imagery. Low level southerly flow around 10
knots was keeping temperatures in the 70-75 degree range at most
locations as of 08z, with dewpoints mostly in the 65-70 range.

Near term (today and tonight)
Ridging aloft will continue to amplify directly over our region
today as the latest in a series of potent shortwave troughs digs
southward down the california coastline, resulting in deepening
troughing over the western third of the nation through Thursday.

Meanwhile, high pressure building over the eastern great lakes and
mid-atlantic states this morning will wedge southward down the
southeastern seaboard this afternoon, resulting in a tightening
local pressure gradient this afternoon. Light southerly winds will
prevail locally this morning, with mid-level cloudiness eroding
by mid-morning as the subsidence inversion around 700 millibars
quickly breaks. Temperatures will likely reach their maximums in
the mid to upper 80s at coastal locations around noon before a
surge of fresh easterly breezes arrive by early to mid afternoon,
with breezy conditions then quickly spreading inland this
afternoon. Isolated convection will likely develop along the gulf
coast sea breeze early this afternoon near the suwannee river,
with a few isolated showers also possible along the wind surge
atlantic sea breeze boundary that will be progressing west of u.S.

301 during the mid to late afternoon hours. Inland highs will
likely reach the mid or possibly even upper 90s before breezy
easterly winds arrive late this afternoon. Dewpoints will crash to
the upper 50s to around 60 during peak heating for locations
along and west of u.S. 301, keeping heat index values mostly below
100 degrees. Temperatures area-wide should fall a few degrees
later this afternoon, with isolated convection possible over our
far western counties in both southeast georgia and the suwannee
valley through around sunset.

A tight local pressure gradient will prevail this evening, and
there may be enough low level moisture for a few coastal showers
to develop over the atlantic waters towards midnight. Breezy
conditions will continue through around midnight at area beaches
before subsiding somewhat during the predawn hours. A few isolated
showers may arrive at area beaches towards sunrise on Thursday,
but chances for measurable rainfall at this time remain around 10
percent for locations along and east of i-95. Onshore breezes will
keep coastal lows only in the mid or upper 70s tonight, while
strong subsidence, clear skies and decoupling winds result in
inland lows falling to the mid to upper 60s.

Short term (Thursday through Friday night)
Predominantly dry weather and high temperatures are expected for
midweek as the high pressure system continues to encapsulate the
southeast us. A backdoor front from the east will help strengthen
the east coast sea breeze on Thursday allowing it to push its way
into inland florida, reaching past the i-75 corridor, with a
slight chance of convection occurring along the sea breeze
convergence in the later afternoon and evening on Thursday.

Onshore sea breeze will be significantly weaker on Friday, with
minimal chances for convection. High temperatures during this span
will be in the low to mid 90s for inland areas and in the upper
80s along the coast, with warmer temperatures occurring on Friday.

Overnight low temperatures are expected to be in the low to mid
60s for inland areas, and in the upper 60s, low 70s, for coastal
areas.

Long term (Saturday through Tuesday)
Potential for record high temperatures for the holiday weekend as
high pressure continues to dominate the weather pattern with
mostly clear skies and no significant chances for precipitation to
develop. Humidity levels will be in the 20s and 30s going into
next week, which will result in a "dry heat" with the heat index
values being very close to the literal temperature. East coast sea
breeze isn't expected to push much further inland than the st
johns river basin for this span of days. High temperatures during
this period will range from the 90s on Friday and then rise into
the lower 100s for inland areas, while remaining in the 90s along
the coast. Overnight low temperatures are expected to be in the
upper 60s and low 70s.

Aviation
Vfr conditions will prevail at the regional terminals. Ceilings
of 8000-10000 feet will be possible through around 15z. Light
southerly surface winds will prevail through the morning hours,
followed by an abrupt shift to easterly early towards 16z at the
coastal terminals, with sustained surface speeds increasing to
near 15 knots by 20z. Breezy easterly surface winds will then
spread inland after 20z, with sustained speeds of 10-15 knots
expected at all terminals except for gnv, where speeds should
remain near 10 knots. An isolated shower cannot be ruled out near
the gnv terminal around 18z-20z, but confidence remains too low to
include in the tafs at this time. Breezy easterly surface winds
will prevail through the evening hours at the coastal terminals,
with a few brief showers and MVFR ceilings possible after
midnight.

Marine
Strong high pressure expanding from eastern canada through the
eastern great lakes region will wedge down the southeastern u.S.

Seaboard today, resulting in a tightening local pressure gradient.

Light southerly winds this morning will shift to easterly this
afternoon, with speeds increasing to around 15 knots and then
possibly strengthening to caution levels early this evening. Seas
will build to 3-5 feet this evening offshore, with 2-4 foot seas
prevailing near shore. Strong high pressure will continue to
shift southward on Thursday, keeping winds around 15 knots both
near shore and offshore. High pressure will then weaken as it
builds over the georgia waters on Thursday night and then over the
northeast florida waters on Friday, allowing our local pressure
gradient to loosen, resulting in decreasing onshore winds and
subsiding seas. Winds will shift to east southeasterly on
Thursday evening, with seas falling back to 2-4 feet over all
waters. Weakening high pressure will then settle over the florida
peninsula this weekend, keeping a loose pressure pattern in place
locally through much of the next week. Light offshore winds are
expected each morning, shifting to southeasterly over the near
shore waters as the sea breeze moves inland each afternoon, and
then southerly wind surges prevailing each evening over all waters
from the weekend through most of next week.

Rip currents: strengthening easterly winds this afternoon will
combine with the outgoing tide to create a moderate rip current
risk at all beaches today. Similar conditions will prevail on
Thursday, followed by a lower risk by Friday and Saturday as
onshore winds weaken.

Fire weather
Extended period of dry weather and above average temperatures are
forecasted for the rest of this week, the holiday weekend, and
into the coming week thereafter. Surface winds not being affected
by the sea breeze are not expected to rise above 10 mph for inland
areas, however with the sea breeze winds extending inland as far
as just past the i-75 corridor reaching speeds of 10-15 mph with
gusts of 20-25 mph possible, along with strengthening transport
winds out of the east during the afternoon and evening. Rh
minimums will be in the mid to upper 30s for inland areas today.
