321 pm edt Fri mar 24 2017

Short term (tonight-Saturday)
Weak mid/high level ridging will hold across the region as surface
high pressure off the mid-atlantic coast drifts east out into the
atlantic ocean, but continues to ridge west-southwest across the
area. This will keep an east to southeast low level flow across
the region continuing to advect atlantic moisture westward leading
to more scattered to broken stratocumulus/altocumulus and maybe a
sprinkle or two over the southern interior and southwest counties.

Otherwise, the low level flow will not be as strong on Saturday as
the gradient relaxes some and this should allow the west coast sea
breeze to develop near the coast during the afternoon.

Temperatures will remain a few degrees above normal with lows
tonight in the mid 50s north to the lower and middle 60s near the
coast from around tampa bay southward. Highs on Saturday will climb
into the lower to middle 80s, except close to the coast where the
sea breeze should hold them in the mid to upper 70s.

Mid term/long term (Saturday night-Friday)
A series of short wave troughs/lows aloft will transit eastward
across the nation through the period... With nearly zonal flow to a
relaxed and meandering upper ridge residing over the gulf of
mexico region. This pattern will keep the bulk of the energy and
frontal boundaries north of our area... Allowing atlantic high
pressure to reach across the state and over the gulf of mexico.

For the most part - a stable and generally dry air mass, model
pwat values run about 1 inch, prevails. The forecast will be rain
free with mostly clear/sunny skies and temperatures on the warm
side of normal, perhaps by 3 to 5 degrees. Winds will initially
be east to southeast with a relaxed gradient permitting afternoon
sea breezes. With time the surface ridge settles south with winds
more southerly to southwesterly.

However, there are two exceptions. The first short wave trough or
low will brush by Sat night or early Sun with some cloudiness
possible. Then the last trough/low is slightly deeper and takes a
more southerly track, pushing a cold front into the gulf for the
end of the work week. The ECMWF has a weaker and slower system
than the GFS which is more robust and faster. For now have leaned
toward the GFS and introduced some low odds of showers across the
northern counties... Although this will be subject to revision.

Aviation
Vfr conditions will prevail at all terminals for next 24 hours.

Easterly winds between 10 and 15 knots with gusts to around 25
knots will continue through late afternoon, then diminish some
this evening. Winds shift to a more southeast direction at 8 to 13
knots mid-morning Saturday then diminish and shift to southwest to
west near the coast as the west coast sea breeze moves inland
during the afternoon. No other aviation impacts are expected at
this time.

Marine
Strong high pressure off the mid-atlantic coast will drift east
well out into the atlantic ocean over the weekend, but continue to
ridge west-southwest across the waters. The breezy easterly winds
will diminish this afternoon falling below 15 knots. However,
during the evening we will see a surge which will bump winds back
to exercise caution criteria overnight. Winds will diminish once
again during Saturday with the west coast sea breeze developing
near the coast during the afternoon before the evening surge
shifts winds back to easterly during Saturday night with a repeat
on Sunday and Sunday night. A similar pattern will continue
through early next week, but winds will remain less than 15 knots
and seas 3 feet or less.

Fire weather
Relative humidity values will remain above critical thresholds
through early next week, but could bottom out near 35 percent
briefly each afternoon. After this afternoon winds are expected to
remain below 15 mph through early next week with the west coast
sea breeze developing near the coast each afternoon. No other fire
weather concerns are anticipated at this time.

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.
