836 pm edt Wed mar 29 2017

Short term (rest of tonight-Thursday)
An upper low over central ks eases eastward to the mo/il border by
late Thu with an upper ridge initially from the fl east coast to the
upper great lakes sliding east... Reaching from the bahamas to the
lower great lakes. A surface reflection of the upper low trails a
cold front south to tx and has a warm frontal boundary that arcs
east then southeast... Exiting the southeast u.S. Coast. As
the surface feature moves along with the upper low the cold
front shifts to the central gulf coast and the waters to the
south. Atlantic high pressure across fl and over the gulf
of mexico this evening retreats out over the atlantic in
advance of the approaching cold front.

The upper ridge dominates through the day Thu with a stable and
generally dry air mass. Model pwat values run 1.0 to 1.25 inches.

Most of this is confined to the lower layers which with light winds
tonight... As the surface axis remains across the state... Will allow
patchy fog to form toward sunrise and mainly inland. During the day
there will be a subtle increase in clouds but sunny to mostly sunny
skies prevail. Winds will become slightly more robust as they shift
from southeasterly to southerly for Thu afternoon as the gradient
tightens... In response to the departing surface high and the
approaching cold front. Temperatures will run on the warm side of
normal although not so much along the coast.

Aviation
30/00z-30/24z.VFR conditions are expected through most of the
period. However limited br mainly inland may impact the fog favoring
terminals at lal and pgd which have tempo MVFR toward dawn. Winds
become light and variable over night... Increase from the SE in the
morning... Then become southerly with modest gusts in the afternoon.

Marine
The afternoon sea breeze is collapsing with winds slackening and
veering back to southeast by morning. Then during Thu the gradient
tightens as high pressure slides away and a cold front
moves into the gulf with winds increasing as they shift to
southerly.

The front moves into and across the east gulf waters late
thur and during Fri with showers and possibly some
thunderstorms. Lighter winds and drier conditions return for
the weekend as high pressure moves in behind the front.

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.
