Aviation Modest increase in onshore moving atlc shra for
upcoming TAF cycle, but coverage impacts expected to be too low to
include in forecast at the time. Light east winds pickup after
14z, with gulf breeze bringing kapf around to wsw after 20z. Winds
become light after sunset 26 00z, with approaching front bringing
potential for winds becoming SW to NW late in TAF cycle.

update... Made a few near-term changes to adjust sky cover upward
and trim slight chance pops over the atlantic in better agreement
with current radar satellite and a consensus of the convection
allowing mesoscale models. Otherwise, the forecast is in good
shape and no other changes are planned for this evening.

discussion...

tonight and Monday... Low-level moisture associated with a weak
perturbation located over the northern caribbean sea southern
bahamas will briefly advect into south florida ahead of a surface
cold front progressing through the southeast CONUS tomorrow.

Forecast model soundings and time-height relative humidity fields
show moisture advection increasing from the southeast tonight,
with the best saturation occurring around 900 mb during the early
to mid afternoon hours on Monday. Thereafter, the perturbation
will begin pushing off to the east as the westerlies associated
with the approaching mid- level trough axis increase. Given this,
will bring slight chance pops into the east coast metro areas
later tonight, increasing them to chance during the late morning
and afternoon, with a gradual decrease thereafter. With cloud
cover increasing from the east tonight, low temperatures will be a
bit milder, and will range from the upper 50s for areas west of
lake okeechobee to around 70 along the atlantic coast.

Tuesday through Sunday... A cold front will pass through south
florida early in the period, as a potent upper perturbation vort
max swings through causing an overall amplification to the upper
trough. A robust pressure gradient will develop on Wednesday into
Thursday as high pressure builds in behind the departing surface
trough. This will bring a period of gusty northeasterly winds from
Wednesday afternoon into Friday morning before the gradient
relaxes. The 1000-850 mb layer averaged wind speeds from the
24.12z GFS solution depict magnitudes over 35 kt over the atlantic
waters and east coast, thus suggesting gust potential during this
time depending upon mixing. High seas should build in the
atlantic as a result, leading to a hazardous period for mariners.

Temperatures during this time shouldn't stray overly far from
seasonal norms, although a somewhat cooler period is likely
towards mid-week given post- frontal conditions with cloud cover
and a few showers. Temperatures should begin moderating towards
next weekend as the low-level flow becomes more easterly.

Marine... Cautionary conditions remain possible over the atlantic
waters through tonight, with improvement on Monday. Hazardous
winds and seas will return for Wednesday evening and continue into
at least Friday morning. Strong wind gusts and seas of 9-14 feet
are possible during this period, and a small craft advisory is
likely to be issued as this event draws closer.

Beach forecast... A high risk for rip currents continues for the
atlantic beaches into this evening, with at least a moderate risk
expected for tomorrow given the residual north to northeast swell.

Onshore flow will increase for mid to late week, bringing a
renewed threat for rip currents. There is also some potential for
minor beach erosion and other coastal impacts from mid to late
week along the atlantic. Keep up with this evolving forecast in
case this threat should increase. It's possible that a high surf
advisory and or coastal flood statement may be needed during this
time.

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.
