Discussion
Locally heavy rainfall near the east coast into tonight...

tonight... Mid level trough will move gradually southeast from S ga
toward N fl with deep moisture continuing over the area through
midnight with short range models indicating some mid level drying
moving in from the NW later tonight. Low levels will remain moist
below 700 mbs with NE low level flow becoming ene toward morning.

Short range guidance indicates an inverted surface trough developing
offshore the treasure coast keeping tightest pressure gradient
across central and NRN coastal sections. Expect showers with some
locally heavy rain to continue stream onshore across central nrn
cstl sections so will continue the flood watch for NRN brevard and
coastal volusia into tonight. Will range from pops from likely near
the east coast to 20-30 percent across lake county. Lows temps will
drop into the lower to mid 70s coastal and around 70 inland.

Wednesday... Surface high pressure near the mid atlc Wed will allow
for NE ene low level winds with pressure gradient also supporting
breezy conditions along the coast and rain chances from 60 percent
coastal to 40-50 percent well inland across lake county. Tightest
pressure gradient will remain across volusia and brevard counties
where the potential for locally heavy rain with persistent rain
bands will persist. Rough surf is expected along east central
florida beaches with the potential for minor beach erosion near the
time of high tide. Highs will range from around 80 along the volusia
coast to lower to mid 80s interior and south.

Thu... Mid level trough aloft pushes east of the area on Thu with
continued low level east northeast flow. Some mid level drying
should lower rain chances to 30-40 percent range with onshore moving
showers from the atlantic through the day. Beach conditions will
remain hazardous for swimmers with strong rip currents and rough
surf expected. Highs in the mid 80s.

Previous extended... Fully developed high pressure along the NE to
mid atlc seaboard will continue a general onshore flow pattern with
eventual airmass drying indicated as higher upstream moisture over
the atlc basin undergoes subsidence related drying late Thu into
fri. A strong marine influence will keep any temperature extremes
moderated with 20 to 30 percent chc precip is indicated by guid
during fri-sat with best chances remaining mainly along the coastal
areas. Expect highs in the l-m80s and lows in the 70s. General winds
will veer back to a sly component sun-mon bringing a return to a
warmer, moist airmass with a stronger front approaching from the
north indicated around early next week.

Aviation
Scattered to numerous showers will move onshore along the coast and
push into the interior into the evening hours. Expect higher
coverage of showers to affect coastal terminals into the overnight
with lower concentration of convection making it inland past this
evening. Periods of MVFR CIGS with convection and ifr vsbys possible
with +ra.

Marine
Tonight... Ne winds will remain strongest across NRN central marine
zones to 20 knots with seas continuing to build to 7-10 ft offshore
by late tonight. Some of the highest seas will make it into the
treasure coast waters tonight as winds increase to around 15 knots
north of ft pierce inlet. Will continue current advisory
configuration with SCA in effect across the SRN waters past late
evening.

Wed... Tightest gradient will continue across the central NRN waters
where winds to 20 knots and seas up to 7-10 ft offshore are
expected. Slightly weaker onshore flow is forecast across the srn
waters but seas still likely to reach 5-7 ft near shore and 6-8 ft
offshore.

Thu-sat... Persistent period of onshore flow will continue for late
week and into the upcoming weekend making conditions poor to
hazardous for small craft operation. Seas 5-7 ft Thu into Friday
will build some into the weekend to 7-8 ft offshore. Winds generally
easterly increasing to near 20 knots Friday into the weekend across
the east central fl atlc waters.
