Above average warmth continues...
Near term Through tonight...
scattered marine cumulus moving ashore this morning with isolated
showers possible along the immediate coast. Seeing a few places
with a slight reduction in visibility from a shallow fog layer but
no widespread issues at this time. Ridge of high pressure to the
east continues to promote easterly flow. Invest 98l moves north
along the western edge of the ridge and away from the area. For
this afternoon, less coverage in way of showers and thunderstorms
as drier air filters in from the east, especially along the coast.
Weak easterly flow still present today so expecting showers to
initially start along the i-95 corridor before slowly working
inland. Best chance for thunder will also be inland (i-75
corridor) during the afternoon hours. Coastal areas then become
dry from late afternoon through evening as an area of below
average moisture (pwat <1.5 inches) settles in along the coast.
More efficient moisture content (pwat 1.6 to 1.9 inches) remains
inland so isolated to scattered convection expected there.
Tonight, the western periphery of the ridge extends over the
peninsula leading to a dry conditions overnight.
Temperatures remain above average with upper 80s lower 90s along
the coast and lower to mid 90s inland. Heat indices between
100-104 inland as well so despite a couple hours of less heating,
much of the area will see the heat continue.
Short term Wednesday through Friday ...
ridging aloft and at the surface will persist over the adjacent
western atlantic during the period. The western third of the
upper ridge will build over the region this mid and end week. A
cold front will migrate over northern georgia, central alabama and
southern central mississippi. For the most part this pattern will
result in a prevailing warm and moist southerly flow, with mainly
diurnally driven scattered storms, with highs in the lower 90s,
lows in the lower to mid 70s. By Friday, as 850-500 mb high
bisects the region along the fl ga border, steering winds will be
swly across southeast ga pushing the storms back toward the coast
for evening storms near the golden isles.
Long term Friday night through Monday ...
high pressure will be stacked across the region this weekend
keeping a deep easterly steering flow in place across northeast
florida and southeast georgia. This pattern is expected to yield
isolated to widely scattered coastal showers during the morning
hours. The convective activity will transition inland through the
afternoon, with storms increasing to scattered areal coverage and
strengthening due to diurnal influences.
Temperatures will be coolest inland at night, and warmest at the
coast. The opposite is expected in the afternoons. This is mainly
due to the water temperatures in the 80s, with onshore flow pushing
relatively milder air off the atlantic at night, and relatively
cooler air in during the day. Hence, little change in day to day
temps given the persistent easterly flow.
Marine cumulus causing few-sct ceilings of MVFR criteria for
coastal TAF sites this morning. As weak easterly flow less than 10
knots continues today, will see a few showers near coastal taf
sites before drying out in the afternoon. Best chance of seeing
thunder inland near gnv so vcts in tafs given low probability.
Everyone dry through the overnight hours.
With high pressure to the northeast, light easterly flow continues
over the waters along with isolated showers. Pressure gradient
stays weak throughout the week keeping wave heights of 3-5 feet. A
front attempts to push south into the area during the weekend, but
is expected to dissipate before affecting the waters.
Rip currents: moderate risk for all area beaches. Long period
swells of 8 to 9 seconds and onshore flow persist today.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
