326 pm edt Tue sep 18 2018

Discussion
Thanks to the presence of a ridge over east central florida today,
winds were from the southeast around the treasure coast and
south southwest for the space coast and north of orlando. This
allowed for the sea breeze to reach inland past the treasure coast
and for the development of clouds followed by storms over lake
and volusia counties this afternoon. This activity is expected to
continue for most of the afternoon as these showers continue to
progress and interact with boundaries that will help in creating
new storms. For tonight, as these showers dissipate, weather
conditions are forecast to clear over land for the later hours of
the night. A few showers will then develop over the atlantic
waters which should remain offshore thanks to the west winds
across the local area.

Wednesday-Saturday (previous discussion)... Rapidly deforming
short wave trough moving offshore the eastern seaboard early
Wednesday will shear out, with embedded lobes of vorticity getting
send westward underneath a building ridge from the ms-oh valleys
into the eastern conus. The small vort will drop SW across the fl
panhandle into the NE gomex on Wednesday, while a second,
elongated and much larger lobe will retrograde westward over the
state late Thursday-Friday. A small embedded cutoff low may try
and develop near or offshore the swfl coast Friday or Friday
night, as the atlantic ridge builds back west toward or into
florida on Saturday.

At the surface, a weak "back door" trough alluded to in last night's
discussion will quickly lay over w-e and become diffuse as it sags
into florida on Wednesday. While the feature will dissipate early
Thursday, its residual moisture will linger over the southern half
of florida into Friday. Weak pressure gradient light surface winds
through Thursday, followed by light onshore flow developing as high
pressure builds NE of florida behind the dissipated trough. Pattern
should favor scattered diurnal convection with highest pops over the
interior (40 north 50 south) with 30 percent along the coast. Temps
will remain a solid category or so above normal through Thursday,
before onshore flow nudges MAX temps back a little closer to normal
Friday-Saturday.

Sunday-Tuesday... The axis of the western flank of the dlm atlantic
ridge will extend across florida early next week, with the surface
ridge axis well to the north of ecfl. This will maintain an onshore
e-se wind flow, with sufficient moisture for scattered (30 coast 40
inland) diurnal convection. MAX temps look to be about a degree or
two above normal with mins about a solid category or so above.

Aviation
Scattered shra tsra will continue to develop this afternoon, mainly
across the northern and interior areas from kism- ktix northward.

Some of the stronger storms will be capable of producing periods
of MVFR ifr visibilities. Tempo groups may be needed for the orlando
area terminals later this afternoon, will be watching to see where
main boundary collisions occur as that is where the majority of the
storms will develop. Terminals from kmlb- ksua should remainVFR for
this afternoon as the east coast sea breeze has already pushed well
inland. Most showers and storms will dissipate after sunset, with
vfr conditions prevailing overnight. Another round of scattered
showers and thunderstorms is forecast for Wednesday afternoon.

Marine
Weak ridge across the east central florida coastal waters this
afternoon, will shift east tonight and a trough will extend to
north florida late tonight. Winds will shift from the south to
southwest tonight keeping an offshore flow through the early
morning hours. Seas will slightly subside tonight, 2-3 feet
nearshore and 3-4 ft for offshore waters.

Wednesday- Saturday... A very slack pressure gradient will result
in a continued minimal to nil wind chop on the local atlantic
waters. The persistent long period swell of the past several days
will continue to wane, with seas subsiding to 2-3ft through
Thursday. As onshore flow develops and starts to freshen, a slowly
increasing wind chop coupled with an 8-10s period groundswell
will push combined seas up to 3-4ft Friday- Friday night and 4-5ft
for much of the local waters by Saturday. &&

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.
