2) Scattered showers and a few thunderstorms are possible this
afternoon, mainly for eastern areas.

3) Minor flood benchmarks may be reached along some coastlines
with high tide cycles tonight and Saturday night.

4) A cold front on Sunday brings additional showers and

.DISCUSSION...
.KEY MESSAGE 1...

The region sees one last day featuring well above normal
temperatures this week.

While not nearly as hot as previous days with NW flow developing
and an incoming trough moving over into the afternoon,
temperatures should still achieve the 70s across most of the
region away from the immediate coast, and perhaps into the lower
80s across NE NJ and parts of the NYC metro. Cloud cover with
the cooler air mass moving in aloft could also be a limiting
factor. The national blend seemed reasonable and in line with
MOS and short range hi-res guidance.

These temperatures still remain about 15 degrees above normal
for mid April. Though a couple sites could tie or break daily
max low temperatures, daily record highs are not in jeopardy,
going up against the hottest April day on record for the region
back in 2002. See Climate section further down for additional
detail.


.KEY MESSAGE 2...

A few showers around early this morning with a pre frontal
trough; activity exits east and offshore by mid morning.

Thereafter, slow moving frontal boundary sags south through the
area into early afternoon, with an upper trough moving in right
behind it. While far from a washout, the incoming cold pool
aloft and subsequent steep lapse rates should help instigate
scattered showers this afternoon, with greatest focus across SE
CT and the Twin Forks where instability and forcing may be
highest. Can`t rule out a few isolated thunderstorms with the
activity, though weak parameters mitigate any severe threat.
Locally heavy downpours however will be possible, with soundings
indicating a long skinny CAPE profile. Minor, nuisance flooding
possible with any stronger cells.

Conditions dry out this evening with loss of any diurnal heating,
and weak high pressure builds in from the north through the first
half of the weekend.


.KEY MESSAGE 3...

Astronomically high water levels with a new moon today could
allow minor flood benchmarks to be reached with tonight`s high
tide cycle for the most vulnerable areas along the western LI
Sound, as well as some of the back bays on the south shore.

A weak onshore flow develops by Saturday, and this additional
component may enhance the potential and extent of impacted
coastline. A Coastal Flood Advisory could eventually be needed
for the Saturday night cycle.


.KEY MESSAGE 4...

A sharp cold front approaches the region on Sunday, bringing
another round of showers and embedded thunderstorms, as well as
a much cooler air mass behind it.

Strong cold air advection kicks in with a NW flow behind the
front and temperatures quickly fall by late in the evening and
overnight. Any lingering areas of rain could even taper as a few
wet flakes across the far interior.

Lows Sunday night drop into the 30s for most, or around 40 in
the NYC metro. Afternoon highs Monday in some areas are progged
nearly 40 degrees colder than what we experienced this week,
with locales outside the urban metro struggling to get out of
the 40s. Steep lapse rates with the cold pool aloft could allow
for some shower development, possibly mixed with ice pellets,
though NBM PoPs have yet to catch on to this potential. The
coldest in the period looks to be Monday night, with a
widespread freeze across the interior, and perhaps even toward
the coast.

The cooler regime appears short-lived, with gradual moderation
returning conditions to above normal by midweek.

&&

.AVIATION /09Z FRIDAY THROUGH TUESDAY/...
A weak cold front moves east of the region by early this
morning. Weak low pressure remains along the front with a weak
trough moving through the area this afternoon into early this
evening.

VFR. A chance of showers remains overnight into early this
morning with VFR conditions. Additional showers are possible
mid to late afternoon with a trough of low pressure, and
continued with the PROB30 group. An isolated thunderstorm cannot
be ruled out this afternoon, however, coverage will be isolated
and chances remain low, with the better chances across southern
Connecticut.

Winds likely remain below 10 kt through the forecast, NW to
variable, veering NNW and then N and NE during the day.


 ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Amendments are possible for timing of showers, and if
convection chances increase this afternoon.


.OUTLOOK FOR 06Z SATURDAY THROUGH TUESDAY...

Late Friday night: VFR with MVFR to IFR possible toward Saturday
morning.

Saturday: Chance of MVFR ceilings.

Sunday: MVFR or lower conditions possible. Showers likely. W winds
gusts 20 kt in the afternoon and evening.

Monday-Tuesday: VFR.

.MARINE...
Conditions are expected to remain below Small Craft Advisory (SCA)
thresholds with a weak pressure gradient through Saturday.

Next potential SCA conditions will be associated with a cold
frontal passage as it moves through late Sunday into Sunday
night. Marginal winds and seas are possible behind the front,
primarily on the ocean. Largely tranquil conditions then
expected early next week, with high pressure in place through
Tuesday.
