Strong to severe storms expected through Sunday...

Update
Atypical strong w-nw flow around the base of ERN us trof has
already pushed in one frontal boundary today with strong to severe
convection and expect another frontal boundary to push into the
region on Sunday with strong to severe storms with damaging winds
the main threat by the late morning and afternoon hours and that
part of the forecast has not changed. For tonight a pre-frontal
shortwave lift convection continues to trigger along the central
al ga border and is expected to track into SW ga late this
evening then into SE ga suwannee river valley after midnight
although it should be on a slight weakening trend but still some
strong storms will be possible before they fade into widely
scattered showers and storms as they reach the remainder of NE fl
and coastal SE ga late tonight. Muggy overnight lows expected in
the 70s tonight with west-southwest flow remaining at 5-10 mph.

Some heating is expected on Sunday prior to the onset of scattered
to numerous convection and expect widespread lower to middle 90s
with heat indices up to 105 degrees, still just below advisory
criteria. Models still not in great agreement on how convection
will fire on Sunday, but overall best chances expect to be across
ne fl with highest rainfall coverage along the i-75 corridor of ne
fl. Storms will be moving at least 20-30 mph and rainfall will be
locally heavy with some training and flooding possible across
inland NE fl during the afternoon hours.

Aviation
Vfr conds this evening with decaying showers storms possible late
tonight, but chances at TAF sites 20% or less so have left out of
forecast for now and have then added back in vcts for all taf
sites by late morning beginning in the 15-17z time frame with
timing to be detailed in later packages.

Marine
Southwest flow will continue as low pressure develops over the
carolinas and drops southward on Sunday. Speeds generally in the
10-15 knot range tonight and may increase to 15-20 knots on Sunday
with small craft exercise caution (scec) conds possible with 3-5
ft seas, mainly over the offshore waters. Offshore moving storms
with wind gusts of 35-50 knots will be possible on Sunday once
again and mariners boaters will need to be prepared for rapidly
changing weather conditions.

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.
