729 pm edt Thu jun 22 2017

Aviation [through 00z Saturday]
Vfr should prevail at all terminals for the next few hours. Then,
MVFR ceilings will spread inland from the coast through the night
to all terminals but vld, and lower to ifr at ecp and dhn (possibly
aby and tlh). Patchy MVFR ifr visibilities are also expected to
be scattered about. By mid-morning, most terminals should be low
endVFR under a broken low cloud deck.

Prev discussion [257 pm edt]
Near term [through tonight]
Wv imagery shows ribbons of drier air feeding into the mid levels of
td cindy, which was near the central la-tx border at 18z. This drier
air mixing in will keep showers and thunderstorms more isolated
locally, with the highest chances in southeast al. Lows will be in
the mid to upper 70s.

Short term [Friday through Saturday night]
Mid level high anchored off the atlantic coast will be the
dominant mid level feature through Friday night at which time this
high will elongate and be replaced by an approaching mid level
trough. This trough will support a surface cold front which will
be entering our northern CWA counties by Sunday morning.

Below climatological rain chances are expected Friday with
slightly higher chances across the northern sections Saturday (se
al and adjacent SW ga counties) with the approach of the trough
and cold front. Temperatures will be in the upper 80s to lower 90s
for highs and in the lower to mid 70s for lows.

Long term [Sunday through Thursday]
Will maintain a blend of the current models and close to the
previous forecast as models continue to be split on how far the
cold front will penetrate into or through the CWA and dry air
moving in from the north. Deep layer trough will be the dominant
mid level feature through Wednesday then be replaced by a mid
level high for Thursday. Rain chances will be around
climatological averages until mid week. Highs will be in the 80s
and lows through the 70s.

Marine
Winds and seas will gradually subside from east to west tonight.

However, moderate south swells will continue into Friday. A return
to low winds and seas is expected by this weekend as a surface
ridge develops across the marine area.

Fire weather
No fire weather concerns.

Hydrology
Rainfall associated with TS cindy has come to an end with generally
4 to 6 inches of rain across portions of SE alabama and the florida
panhandle with lesser values further east into south central georgia
and the florida big bend.

Some of the faster responding rivers in the panhandle, like the
shoal river are cresting this afternoon just below flood stage.

Modest rises continue in the pea chochtawhatchee basin in SE alabama
and expect rises to just below flood stage further down the basin
into the florida panhandle into early next week as water from
southern alabama arrives.

In south georgia and the florida big bend, only small rises have
occurred and are continuing with nearly all locations remaining
below flood stage. Only exception is the sopchoppy river where
heavier rains fell in the coastal basin of this river. The river
will crest about 2 feet below flood stage early this evening.

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.
