Aviation
Front slowly moving across south florida has shifted winds
northerly across all terminals with MVFR CIGS continuing through
sunrise. CIGS will improve toVFR behind the front after sunrise
with winds shifting northeast. Northeast winds begin to increase
late tonight as gradient increases especially terminals near the
coast. Chance of shra has lowered, therefore, eliminated vcsh for
all sites for today.

discussion...

short term (today through Saturday)
weak cold front has cleared south florida overnight, and resides
just SE of the peninsula, evidenced by band of showers. Behind the
front, little in the way of cool or dry air has moved in;
temperatures remain in mid 60s to low 70s. Overcast skies have
precluded fog development for the most part this morning.

Heading into the weekend, zonal flow will assist in the cold front
stalling over the florida straits gulf of mexico, as strong
surface ridge resides over mid-atlantic. The pressure gradient
between the two will lead to increase wind speeds through the
period, starting out of the north tonight into Thursday, then
transitioning ene later Thursday into Friday, then SE by Saturday.

While low-level flow will be predominately E ne, swly flow aloft
will lead to abundant mid-level moisture overhead, and this
overrunning situation should lead to at least isolated shower
activity over southeast florida through tonight, before an overall
drying takes place.

Although significant cold air is not expected, temperatures today
and especially tonight will be noticeably lower. Minima will be in
the upper 40s over much of the northwest interior, with 50s
elsewhere, except low 60s along the east coast. Temperatures will
gradually warm thereafter as stronger east wind modify overnight
lows. Maxima will remain in the 70s into the weekend.

Long term (Saturday night through Tuesday)
a mid upper level trough will near for the latter part of the
weekend. This will lead to increasing southerly flow, warmer
conditions, and significant moisture advection into the region.

The aforementioned trough will allow cyclogenesis over the central
gulf in association with the decaying stationary boundary. This
will likely to showers over the region Sunday into Monday.

Convection cant be ruled out during this period, but will wait for
some run-to-run consistency before introducing into the grids.

Best dynamics and moisture plume are progged to be north of the
region, north of i-4 corridor. Although ECMWF is a bit slower with
progression of low-pressure across north florida and subsequent
fropa over south florida, it appears cooler and drier conditions
will move into the region at some point Monday or Monday night,
with below average temperatures on tap for Tuesday.

Marine...

small craft advisory has been hoisted for atlantic waters from 4z
tonight through Thursday night, with hazardous conditions likely
expanding to additional marine zones and extending through the
weekend. North winds behind a cold front will increase today and
become hazardous tonight. Winds of 20 to 30 knots with higher
gusts are expected Thursday and Friday, gradually veering easterly
by week's end. This will be due to pressure gradient tightening
due to stalled front lower pressure to the south and west and
strong hipres over the mid-atlantic. Seas will also increase due
to the wind and some northeasterly swell is also anticipated.

Conditions are likely to remain poor through the weekend.

Beach forecast...

rip current risk along east coast beaches will increase tonight
and Thursday as NE wind increases. Strong east winds Friday into
the weekend will likely lead to a high risk of rip currents on
atlantic beaches. These winds are being caused by tight pressure
gradient between front lopres to the south and west and hipres
centered over the mid-atlantic.

Fire weather...

light wind and stable conditions will lead to poor dispersion over
much of interior and gulf coast sections of south florida today.

Stronger winds will improve dispersion Thursday, with no fire
weather concerns heading into the weekend.

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.
