Discussion
Today and Friday: axis of the ridge centered over the western
atlantic will continue to sink south into the region as broad
upper level trough moves into the eastern us. This will bring
light southerly flow across south florida, allowing both
seabreezes to develop and move inland the next two afternoons.

The south component will also continue the warming trend with
afternoon highs in the mid to upper 80s, with a few spots over the
interior reaching into the lower 90s.

Very weak frontal boundary moves down the peninsula late on Friday,
bringing an east-northeast wind surge with it overnight as the
boundary stalls out across the region. Increasing moisture pooled
along the boundary along with the low level convergence will lead to
increasing showers Friday night.

Saturday through Wednesday: frontal boundary is forecast to stall
out somewhere across the state through the weekend, acting as a low
level focus for shower development. Models continue to suggest that
overall deep moisture and instability will remain limited on
Saturday, suggesting as pattern of low topped showers moving from
east to west in the brisk low level easterly flow.

Potent low pressure system is forecast to slide eastward over the
southern CONUS on Sunday, increasing the low level south-
southeasterly flow and southwesterly aloft across our area. A broad
area of isentropic lift ahead of the low will help to enhance
precipitation coverage Sunday into early Monday, though the best
focus may end up just to our north and east.

Models continue to keep sufficient CAPE in place Sunday and
Monday that along with the passing vort maxes and upper level jet
in place, there will be enough instability for the mention of
isolated thunder. The operational GFS forecast pwat values
approach 1.8" during this timeframe, and though ensemble values
are a little lower, this combination suggests the possibility of
heavy rainfall at times.

The upper level low is forecast to slowly open into a trough as it
slides east, gradually pushing the front back through the region
with a clearing trend towards midweek.

Marine High pressure gradually sliding further east will keep
good boating conditions across south florida through the end of the
week. Prevailing flow veers more southerly today as the ridge axis
slips into the region, and then light and variable on Friday as a
weak frontal boundary moves into the state. Expect both seabreezes
to develop both afternoons, with local speed enhancements near the
coast. Conditions are forecast to deteriorate Friday night into the
weekend as strong east-northeast winds filter in behind the cold
front that will stall out across the region.

Aviation MainlyVFR though some fog low CIGS overnight could
affect apf with sub-vfr conditions possible. Conditions should
improve toVFR around sunrise and persist through the day.

Seabreezes are expected to develop and push inland today, which
will produce an onshore flow at most terminals through a good
portion of the day. The wind should become lighter and variable
overnight.

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.
