Area Forecast Discussion
National Weather Service New York NY
431 PM EDT Wed Apr 4 2018
.SYNOPSIS...
High pressure gradually builds in through Thursday, followed by
another frontal system late Thursday night and Friday. Another
low is forecast to track off the Mid-Atlantic coast Saturday,
with another coastal low possible for next Tuesday.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
On the heels of a strong cold frontal passage, gusty west
winds will continue through this evening with steepening lapse
rates and the potential for 40 to 50 kt wind gusts mixing down
to the surface. The wind event has been slower to develop and
it is seeming less likely that widespread 50 kt criteria will
be met for those areas under a high wind warning. The higher
elevations will be most susceptible and to the lee of the
higher terrain due to downslope flow. This will have to be
watched closely though over the next few hours to see how the
event evolves. For the time, there are no changes planned to the
wind hazards.
Winds will gradually diminish late tonight and into the morning
with clear skies. Lows will drop to around freezing, which is
below normal by 5 to 8 degrees.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY/...
High pressure builds to the south and west of the area on
Thursday and then off the Mid Atlantic coast Thursday night. A
wave of low pressure over the Midwest Thursday night then lifts
to the northwest of the area Friday morning with light
overrunningprecipitation. Onshore flow that develops ahead of
the system will gradually warm the boundary layer toward morning
with light snow mixing with and changing to rain from south to
north. Snowfall amounts will be light and generally under an an
inch. Liquid equivalent will be about one to two tenths.
Highs on Thursday will be below normal in the mid 40s, with
lows in upper 20s to upper 30s Thursday night before
temperatures begin to warm toward daybreak. With a warm frontal
passage Friday morning,highs will jump back to seasonable
levels in the 50s.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
An unsettled pattern dominates the long term period with the
potential for accumulating snow once again.
A cold front will quickly follow through Friday night but with
little moisture. All eyes then turn to the Plains as energy is
gathering along the tail end of the front. General consensus is that
the low will pass to the south on Saturday but there continues to be
enough signal for a northward trend, especially with a strong 250 mb
jet near or just north with the region near the favored right
entrance region. The ultimate extent of the precip shield will be
determined by the track of the wave and any added lift from the jet
which models are trying to key in the position and strength of.
There are hints at a faster timing so how far east the cold front
will get will be key in determining precipitation type. Current
thinking is a general 1-2 inches.
Brief high pressure builds in Sunday afternoon and early Monday. A
stronger, more organized coastal low is possible on Tuesday. This
far out, have capped PoPs at chance, although it looks like it could
be mainly a rainfall event.
&&
.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
High pressure builds across the region tonight with VFR conditions.
Strong and gusty west winds expected into the early evening hours.
Gusts may reach 40 KT this evening but taper off after midnight.
With daytime heating, west to northwest winds will pick up again
Thursday 15-20 kt with a few gusts to 30 kt possible.

subside to SCA condition by Thursday morning.
Winds and seas will build late Thursday, with solid SCA
conditions on Fri.
Seas will remain above SCA levels Friday night, but with winds
diminishing significantly. Low pressure off the Mid Atlantic
