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.

Prev discussion issued 721 pm edt Sun mar 24 2019
aviation...

primarilyVFR conditions are expected through the period with an
occasional brief MVFR ceiling possible. Some showers will be
possible on Monday, but expected coverage is too low to include
in the tafs for now.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
