Short term (tonight-Saturday)
Upper trough holds in W atlantic while upper ridging from the
gulf of mexico into the ohio river valley gets dampened as
the strong S plains low slowly moves eastward. Weak frontal
boundary at the surface washing out over the central to
south fl peninsula tonight and Saturday with high pressure
over the great lakes tonight splitting and sliding to the
carolina coast Saturday veering low level flow from NE tonight
to SE late tomorrow. Evening NE wind surge for occasionally
gusty winds and pleasant sensible wx condition this evening
into overnight. Models indicate low level moisture to increase
enough to produce low topped diurnal seabreeze showers and
possibly a few storms for the area late sat. Temps to remain
within a few degrees of seasonal averages.

Long term (Saturday night-Friday)
A closed upper-level low will move across the deep south this
weekend, with an associated surface low and frontal boundary moving
into the southeast. Rain chances will be on the rise on Sunday along
with rising dew points on a south to southeast wind flow ahead of
the cold front. These features will continue to shift eastward for
Monday, which looks like a cloudy and wet day with rain chances
possible at almost any time. Coverage will likely be highest in the
afternoon away from the immediate coastline as an onshore wind helps
to increase convergence across the interior.

The mid upper-level low will be slow to clear out on Tuesday, so
conditions will remain on the cloudy side for the first half of the
day, with a few showers still possible. Some relatively dry air will
then move over the region on Wednesday, followed by another dry
frontal boundary on Thursday. Temperatures both days will be fairly
seasonable. The next frontal system looks to approach for the end of
the week into next weekend, with a slight chance for showers.

deck areawide this afternoon. NE low level flow overnight to produce

Will hoist scec headlines over the northern central waters
tonight. Gradient to relax with seabreeze Saturday afternoon.

se Sunday. Southern storm system with cold front to move

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.
