Discussion
Current radar shows a few swift moving rain showers lurking
offshore the east coast this afternoon -- wouldn't be surprised
if they moved inland as the day progresses, especially with breezy
se flow going on. Otherwise, partly cloudy to mostly clear skies
will prevail for the duration of the evening before some low-mid
level clouds advect in from a brief burst in shallow low-level
moisture. SREF is hinting at the chance for fog tomorrow morning,
though confidence is too low to mention in the grids at this time
-- am thinking it is more of a low cig event and or mist,
especially since winds are favored to remain near or above 5 mph
throughout the night for the western central interior. Low temps
are expected to drop into the mid-upper 60s across the interior
and gulf coast with low-mid 70s across the east coast, coming
close to breaking warm minimum temps... See climate section
below...

for the next couple of days, mid-level ridging aloft will promote
a generally stable and warm air mass across the region, allowing
for well above average temperatures at all climate sites. For the
most part, moisture will stay relatively limited... Model derived
pwat values run 0.70-1.20 inches through Friday. This along with
subsidence will keep rain chances on the lower side, with pops
capped at 30% through Friday evening.

By the weekend, increasing moisture levels look to plague the
region, increasing rain chances in the process. No thunderstorms
are anticipated as 0-3 km bulk shear stays on the lighter side and
cape values remain rather weak. On Sunday, a developing low
pressure across the great lakes region will extend a cold front
across the fl panhandle and central eastern gulf of mexico. As the
aforementioned mid-level ridge weakens and retreats
southeastward, this cold front will begin its march towards the
cwa throughout the course of the day.

By Monday, this front comes fairly close to passing through the
region as. Right now, long range models (gfs and ecmwf) have the
front stalling near lake okeechobee. Whether or not the front
makes it this far south is really up to how far southeast the
ridge retreats, but either way it shouldn't be very impactful
other than providing scattered rain showers early next week.

Marine
Breezy SE to E winds, passing showers, and building seas are
expected to continue tonight over the atlantic waters as the
pressure gradient tightens. Small craft should exercise caution as
winds could reach 15 to 20 knots with seas around 5 to 6 feet in
and around the gulf stream. Winds and seas subside somewhat
tomorrow through the weekend, though small craft exercise caution
may be in place again at times.

A NE swell could impact palm beach county tonight into mid morning
tomorrow. While coastal flood advisory conditions are not
forecast, some increased surf and wave run up may be possible. A
high risk of rip currents is in effect through tomorrow and may
be expanded into Friday.

Aviation
Although isolated showers are possible throughout the period,
coverage should be sparse and impact minimal, so not included in
tafs. Similar scenario regarding cig restrictions; generallyVFR
conditions will prevail. Southeast wind 15-20 kt will remain gusty
until around sunset, then diminish to 5-10 kt. Southeast wind
returns Thursday at speeds of 10 to 15 kt.

Climate
Record highs and warm mins for the next two days...

fll and apf have the best chance to at least tie their
record warm min... February record high min temps may be broken
or tied the next couple days as well.

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.
