Synopsis
A warm front remains well north of the region this afternoon. A
cold front approaches tonight and moves across the area
Saturday. A series of frontal boundaries will move across the
tri-state area Sunday through Tuesday. A large area of high
pressure builds in thereafter.

Near term until 6 pm this evening
A warm front is located well north of the region with a pre-
frontal trough developing in the lee of the appalachians. The
local region is in the warm sector with a warm and humid airmass
in place. Temperatures range from upper 70s to mid 80s this
afternoon although much of the region will be in the upper 70s
to lower 80s. Dewpoints are in the lower 70s.

Showers are located near and north of nyc with overall shower
activity expected to be isolated in coverage but by late
afternoon expecting scattered showers as well as thunderstorms.

These will be mostly north and west of nyc.

The clouds have been abundant so this has limited the surface
based CAPE and instability. There is some shear that increases
towards the evening as winds at 3kft increase to near 30kt. This
will allow for convection to become more organized.

The moderate risk of rip current development continues through
this afternoon, due to building southerly winds waves and a 2
ft long period SE swell.

Short term 6 pm this evening through 6 pm Saturday
Northern stream longwave trough continues to deepen into the
upper mississippi river valley and great lakes through the
period... With the shortwave remnants of cindy shearing northeast
towards the region late tonight into Saturday morning. At the
surface... A cold front over the great lakes will slide east
towards the region tonight... With the remnant circulation of
cindy riding NE towards the region along the front.

Leading edge of southern stream shortwave energy and pre-
frontal trough approach the region this evening. Will have to
watch for convection developing over central eastern pa this
afternoon... And whether line segments can translate east in the
moderate mid- level flow into the lower hudson valley NE nj
before instability begins to wane. A conditional low threat for
severe winds gusts exists mainly NW & W of nyc if this activity
survives.

The parade of shortwaves late evening into the overnight and
tropical airmass will keep a threat for iso convection with
heavy downpours overnight. Coastal stratus fog development
possible with high dewpoint airmass advecting across E LI se
ct late today this evening.

Main concern during this period will be approach of cold front
and remnant low of cindy late tonight Saturday morning.

Environment presents a threat for flash flooding along and just
to the south of the path of this low... With pwats in excess of
2+ inches and corfidi vectors indicating potential for slow
moving or back building convective elements. Also can't rule out
an isolated severe wind tornado threat if any MCS type activity
develops in a weak instability but high shear helicity and low-
lcl environment.

745am update... 06z guidance is indicating that this feature may
track to the south of the region. If 12z guidance continues
with this theme... The above mentioned severe flash flood threat
may end up south of the region.

Drying conditions in the wake of the cold front and cindy
circulation Saturday afternoon... With highs in the mid to upper
80s.

A high risk of rip current is likely Saturday with building
southerly swells and wind waves.

Long term Saturday night through Friday
Nwp is in agreement that a broad upper level trough will remain east
of the rockies into early next week. The h5 flow then flattens from
west to east as a cutoff low pres system moves through the western
canadian provinces... Eventually consolidating with a vortex over
northern quebec. This will sharpen the trough with its axis passing
through Tue night followed by weak ridging for the remainder of the
forecast period.

In terms of sensible weather... Not a whole lot to talk about. A
few cool frontal boundaries will pass through the local
area... The first Sunday aftn eve with just a chance of isold
showers. Mid level warming will keep instability in check so no
tstms in the forecast.

The second boundary approaches on Monday and is very slow to
move through the area. It may become hung up... Before pushing
east Tue night. Despite a decent shortwave and being in the rrq
of a 120+ kt upper jet... Moisture looks very meager... Thus have
kept the forecast dry. Moisture is still limited on tue... But
there could be enough for isold showers tstms in the aftn.

Dry and seasonable weather then returns for the remainder of the
forecast period.

Aviation 18z Friday through Wednesday
Low pressure tracks through eastern canada this afternoon into
Saturday morning with an associated cold front approaching this
evening and moving through the terminals 12z to 16z Saturday.

Winds will be generally from the southwest 220 true, with gusts to
around 20 kt. Sea breeze influence will keep the winds more
southerly along the coastal areas this afternoon. With the passage
of the cold front winds shift to west to northwest, to the left of
310 true, and become gusty Saturday morning.

GenerallyVFR with occasional MVFR ceilings this afternoon.

Restrictions in fog and showers develops after 06z, isolated to
scattered thunder is possible late this afternoon and this evening.

Another round of showers develops late tonight with the chance of
heavy rain and ifr visibilities.
