Area Forecast Discussion
National Weather Service New York NY
357 PM EDT Tue May 2 2017
.SYNOPSIS...
A cold front moves through tonight, followed by another on
Wednesday. High pressure builds briefly across the area on
Thursday before giving way to an approaching frontal system
over the Mississippi Valley. The system moves across the area
Friday into Friday night with the low passing to the northwest
across the Great Lakes. The associated upper low will then
remain over the Northeast through early next week.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
An upper trough shifts through the Northeast tonight with a cold
front passing through the forecast area this evening. Moisture is
limited, so no rainfall is expected with its passage. Winds diminish
overnight, and low temperatures should be near normal.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
A cold front moves through during the late morning/early afternoon
hours with some cloud buildup, but with no rainfall expected. Breezy
behind the front with diminishing clouds later in the afternoon.
High temperatures will be a little below normal in most cases, but
for the south shores of LI and CT they will be closer to normal due
to offshore winds. Mainly clear with diminishing winds for Wednesday
night as a high pressure center shifts in from the west.
Patchy/areas of frost are expected across mainly the far northern
zones overnight with light to calm winds, lows in the mid 30s, and
sufficiently low dewpoint depressions.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
Global models remain in good agreement with taking an upper low
over the Mississippi Valley at the start of the period NE into
the Great Lakes Thursday into Friday, eventually becoming
nearly stationary across the Northeast through early next week.
High pressure will briefly be over the area on Thursday, giving
way to the aforementioned low and its associated frontal
system. A deep-layered southerly flow ahead of the system will
set up a strong warm conveyor belt along the east coast with a
moderate to heavy rainfall event Friday into Friday night. The
potential exists for a widespread 1-2 inch rainfall event with
localized higher amounts due to elevated convection.
The heaviest rains exit the area Friday night, but the rest of
the weekend into early next week will remain unsettled as a
highly amplified omega blocks resides across the lower 48. The
upper low responsible for the rain on Friday will become nearly
stationary over the Northeast with multiple pieces of shortwave
energy rotating about it. There are some timing issues and
phasing issues with multiple upper low centers. Regardless
though, it looks to be unsettled with bouts of showers over the
weekend and into early next week. Gusty winds will prevail most
afternoons.
Temperatures will trend from near normal at the start of the
period to below normal for the second half of the weekend into
early next week. Lows Friday though will be mild due to a
strong SE flow, gusting 20 to 30 mph. with dew points into the
50s.
&&
.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
A cold front is moving east of the area this afternoon, followed
by another cold front that moves through this evening.
All areas will be windy out of the W this afternoon and this
evening. Only a slight 20 to 30 degree shift in the wind with
the cold front passing though this evening. The winds diminish
during the overnight before coming back by late Wednesday
morning. VFR conditions throughout the taf period.

.OUTLOOK FOR 18Z WEDNESDAY THROUGH SATURDAY...
.Wednesday-Thursday...Mainly VFR. Gusty winds Wednesday, W
15-20 kt with gusts near 25 kt.
.Thursday night-Friday...MVFR or lower conditions with rain. SE
winds 10-15 kt with gusts 25 kt Friday with LLWS possible.

10-15 kt with gusts up to 25 kt.

night, with VFR conditions on Sunday. Winds SW.
&&
.MARINE...
SCA conds continue into this evening. Will leave the non-ocean
waters with an ending time of 02z this evening as conds fall below
criteria for at least 12 hours before gusts to 25 KT or greater
return Weds morning. Another SCA will then probably be needed. For
the ocean waters, had enough confidence to extend the SCA in time to
last into Weds evening east of Fire Island Inlet. Winds and seas
then diminish further overnight Wednesday night as a high pressure
center approaches the waters.
High pressure briefly builds across the waters with sub-SCA
conditions on Thursday. SCA conditions are likely to return to
all waters late Thursday night and Friday. A 50-60kt LLJ will
track across the area Friday although an inversion over the
waters will keep most of this from mixing to the surface. Winds
decrease Friday night, but may remain near SCA levels over the
weekend on ocean waters with high seas.
&&
.HYDROLOGY...
No widespread hydrologic impacts are expected through Thursday.

night. At this time, it appears that only minor nuisance
flooding could impact the area.
