Area Forecast Discussion
National Weather Service New York NY
1250 PM EDT Wed Mar 22 2017
.SYNOPSIS...
Gusty northwest winds will continue through this evening in the
wake of a cold front. High pressure then starts building from
the Great Lakes, moving more into the region tonight into
Thursday. The high moves offshore Thursday night. A warm front
passes Friday, followed by a cold front Saturday. The front
remains south of the area as high pressure builds to the north
over the weekend. Waves of low pressure impact the area early
next week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A good solid Wind Advisory event across the area with this event
being on the higher end of things in some areas. A few reports
of branches down from the wind in CT and on Long Island were
received. Gusts have exceed 45 mph in several locations on land
especially across Queens, Long Island and CT. Headlines look
good and will stay as is at this time.
Tweaked cloud cover as cloud streamers being generated off of
Lake Ontario are working more south-southeast or due to south
based on trajectory and are staying mainly west of our CWA.
Temps will remain steady or slowly fall through mid afternoon
with any bigger tank in readings coming this evening.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
Dry and cold through the period. Jet stream still south of the
region this evening with more of a ridging trend thereafter as
the jet starts to move back north.
Winds starts to taper down tonight, with Long Island/NYC still
seeing some higher gusts until 8pm. Wind advisory still in
effect early part of this evening (6-8pm) for NYC and Long
Island. The pressure gradient thereafter starts to lower with
the closer proximity of high pressure building in from the NW.
Lows tonight and highs Thursday used a blend of MAV/MET/GMOS.
Well below normal values with lows tonight in the lower teens to
lower 20s and highs Thursday in the upper 30s to lower 40s.
Thought for the lows tonight, the radiational cooling will be
partially mitigated due to mixing with winds in the boundary
layer. Wind chills drop into the single digits for most
locations.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Unsettled weather through much of this time frame.
Model details remain uncertain, but chances for wet weather look
likely through the period.
A warm front passes Friday as high pressure departs to the east.
Generally light precip is expected as the warm front moves through,
certainly not a wash out, or significant event.
A cold front will likely approach from the north as a ridge of high
pressure moves across central canada, pushing the front southward.
The front sags just to the south late Saturday, and will remain
there for several days. Once again, some wet weather is possible
Saturday and Saturday night as the front moves through, but not a
wash out.
Then, attention turns toward upstream trough and low pressure as it
approaches from the west Sunday and Monday. Looks like a good chance
for rain, or a wintry mix across the interior, at times. This trough
passes, with yet another one on its heels Tuesday. More wet weather
expected by that time.
Temperatures will remain on the cool side, especially once the front
passes to the south late Saturday. Near normal temps are expected
Friday, with slightly above normal readings for Saturday.
Thereafter, readings in the 40s during the day, with 30s at night
are forecast as the local area remains north, or on the cool side of
the front.
&&
.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Canadian high pressure is building into the region.
VFR through the TAF period.
NW winds 15-20KT with gusts up to 30KT into late morning. The
strongest winds will occur from 16Z-23Z when NW winds will be
sustained near 25KT with gusts up to 40KT. Gusts begin to drop
off after sunset and diminish after midnight.

.OUTLOOK FOR 00z THURSDAY THROUGH SUNDAY...

.MARINE...
Winds have picked up this morning across the coastal waters
behind the front with numerous gusts to over 40 kts and waves at
the buoys south of Fire Island now up to 7 ft. Gusty winds of 35
kts+ and waves of 4 to 7 ft will continue through early this
evening before conditions start to decrease tonight from west
to east. Gale warning remains until 06Z Thursday. SCA remains
likely thereafter late tonight into early Thursday before all
waters go below SCA for the rest of Thursday.
High pressure moves across the waters Thursday night, and passes
well to the east Friday. Winds diminish during this time, but begin
to increase from the SW later Friday into Friday night.
A cold front approaches from the north Saturday, and settles near or
just south of the waters Saturday night into Sunday. Winds diminish,
and turn toward the E/NE. Speeds increase yet again Sunday as high
pressure builds well to the north.
&&
.FIRE WEATHER...
NW winds of 15-30 mph with gusts 35-50 mph and min RH dropping
to near 20 to 25 percent should help dry fine fuels across the
snow barren ground. This will enhance the threat for brush fire
spread in those areas today. Winds are lighter but similar RH
values are expected for Thursday.
&&
.HYDROLOGY...
Unsettled weather from this weekend through early next week may
result in an inch or more of precipitation. However, this would
occur over a prolonged period and would be intermittent, so no
hydrologic concerns are anticipated.
