309 pm edt Fri mar 22 2019

Near term Through Saturday night...

high pressure at the surface and aloft builds eastward over our
forecast area during this period, with dry conditions and a
warming trend. Interesting, consensus of all guidance shows
tonight's lows and Saturday's highs several degrees warmer than
all MOS guidance which are in pretty good agreement... Will go
in between the cooler MOS guidance and warmer consensus.

Short term Sunday through Monday...

high pressure moves east of the area Sunday, while a cold front
approaches from the west on Monday. Above normal temperatures
are expected, along with an increase in cloudiness.

Long term Monday night through Friday...

cold front moves across the area Monday night into early Tuesday
with scattered showers and isolated thunderstorms. A 1038mb high
builds over the northeastern states wed, setting up a nor'easter
pattern for our area Tue through Thursday. Should see breezy
conditions, windy along coast, with coastal showers that could
affect the fl coastline at times. Brief return to slightly below
normal temperatures mid-week before warmer conditions return by
Friday.

Aviation Vfr next 24 hours... Gusty winds this afternoon
should diminish toward evening.

Marine Will let SCA expire this afternoon as seas are expected
to fall below criteria. High pressure will gradually build over
the waters through Sunday... Then east of the waters Monday. The
result will be lower winds seas through this period.

Winds seas increase ahead of a cold front that approaches Monday
night, and moves across the waters early Tuesday. Strong high
pressure builds north of the waters, resulting in a substantial
increase in winds seas as a nor'easter pattern sets up, with sca
conditions expected Tuesday night through at least Thursday.

Rip currents: low risk expected Saturday.

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.
