Synopsis
Low pressure tracks from south of long island to near nova
scotia by Monday evening. Meanwhile a series of cold fronts
cross the area Monday afternoon and night. Deep low pressure
over the canadian maritimes Tuesday gives way to high pressure
mid week. Another low impacts the area Thursday and Friday, then
moves into canada next weekend.

Near term until 6 am Monday morning
Reports of snow have made its way all the way into new york
city, with central park reporting some snow. This may be due to
cold air draining down the hudson river valley into the city.

At the time, there was also bright banding as well as more
intense precipitation as compared to other areas, which allowed
the column to cool and thus supported snow for about an hour. As
the precipitation lightened up, the snow has changed back over
to rain. There is another band over nassau county and southern
queens which may allow frozen precipitation there as well,
therefore, mentioned rain or snow or sleet for a large area,
mainly from new york city into northeast new jersey, all of the
lower hudson valley, and portions of southwest connecticut.

However, much of the precipitation is tapering off in these
areas, and should end over the next few hours.

A cutoff low tracks to the southeast of long island through
the overnight. Sfc low does the same. Expect precipitation to
taper off from W to E overnight with the exiting of the the low
level jet. Across interior zones, the question is how fast does
low level cold air work in to change the rain to sleet snow.

For now have the potential for up to an inch of sleet and snow
across northern interior zones, but could just as easily see no
accumulation if the low level cold air does not arrive in time.

Lows tonight should be around 5-10 degrees above normal.

Short term 6 am Monday morning through Monday night
Northern stream shortwave ridging crosses the area Monday
morning, with associated subsidence keeping things dry. The
axis of a northern stream trough then pushes through the area
Monday afternoon and then continues to push SE off the mid-
atlantic and NE seaboard Monday night. Low levels likely will be
too dry for any precipitation on downsloping low level NW flow
- but given expected low level instability cannot rule out a
stray flurry or sprinkle Monday afternoon.

It will become quite gusty Monday afternoon and night with gusts
of 25-35 mph Monday afternoon and 30-40 mph Monday night. At
this time it appears the area should remain below wind advisory
criteria Monday night. However, given either slightly stronger
cold air advection or a tighter pressure gradient and low end
wind advisory gusts could be achieved Monday night both near the
coast and at higher elevations inland.

Highs on Monday should occur by early afternoon with slowly falling
temperatures later in the day. Highs should peak out in the
lower to mid 40s and wind chills by late afternoon from the mid
20s to lower 30s.

Lows Monday night should be near normal, with wind chills
generally in the 10s by late Monday night(around 20 nyc).

Long term Tuesday through Sunday
General model agreement noted as upper ridge and sfc high builds
Tuesday-Wednesday ahead of digging shortwave energy that develops
into an amplified trough over the mississippi valley by Thursday.

The sharpening trough looks to close off near the southern
appalachians as a surface low deepens. The low moves north up the
appalachians on Friday. This stacked low lifts northward into canada
next weekend. A warm front approaches and lifts northward Friday,
and lagging sfc front trough passes Saturday as the low traverses
well to the north.

A noticeably less amplified overall mean flow is expected toward the
end of the period.

Looks like the best chance for rain occurs later Thursday night and
through the day Friday as a broad area of moisture sweeps northward
across most of the east coast.

Gusty NW winds Tuesday will add to the chill, but winds diminish tue
night and Wednesday as the pressure gradient relaxes. E SE winds
increase Thursday-Thursday night ahead of the warm front, with gusty
s SW winds Friday. These winds veer to the west, and remain rather
gusty through the weekend as a tight pressure gradient remains in
place.

Temps remain right around or slightly below normal Tuesday-Wednesday
before rebounding to above normal thu-Friday. Readings return to
normal in CAA behind the storm next weekend, especially Sunday.Day.

Aviation 03z Monday through Friday
Low pressure southeast of montauk point will move up the coast
overnight and into Monday while deepening. By Monday afternoon
the low will be in the canadian maritimes, and then move slowly
north through Monday night.

MVFR conditions continue overnight with light rain ending
05z to 06z west, and 09z to 10z east. A mix of light rain, snow,
and sleet will be possible across portions of the lower hudson
valley and into the nyc metro area.

After the precipitation ends, MVFR ceilings will likely remain
overnight, until around 12z Monday when conditions improve to
vfr.

Winds will be northerly 10-15kt with gusts 20-25kt. Gusts
become more occasional, and possibly end for several hours late
this evening, and into the overnight. Winds will be backing to
the NW overnight with NW winds and gusts increasing Monday. The
highest winds and gusts will be during the afternoon and into
Monday evening. Sustained winds increase to around 20kt with
gusts 30-35kt.

Outlook for 00z Tuesday through Friday
Monday night Vfr. Gusty NW winds 15-20kt, g25-35kt, gradually
diminishing late.

Tuesday-Wednesday night Vfr. NW wind g15-25kt possible Tuesday, w-
wsw winds g15-20kt possible Wednesday.

Thursday Vfr, possibly becoming MVFR or lower late with rain.

Llws possible late.

Friday MVFR or lower in rain. SE winds 15-20kt g30kt
possible. Llws.

Marine
Sca now in effect ocean waters west of moriches inlet tonight.

Sca all non ocean waters (gusts up to 30 kt through Monday).

Gale gusts should fall off by midnight east of moriches inlet.

Gale gusts should return on the ocean waters by Monday
afternoon and on all waters Monday night in response to
strengthening low level cold advection. So have issued a gale
watch for Monday and Monday night for the coastal ocean waters
and for Monday night for the non-ocean waters.

Gusty NW winds persist Tuesday as deep low pressure moves along the
canadian maritimes and a tight pressure gradient remains in place.

Gale force gusts are possible, especially the ocean waters and
eastern LI sound before winds diminish Tuesday night and Wednesday.

The diminishing winds are due to high pressure, as it builds over
the waters.

Winds eventually shift around the s, then E SE Thursday as the high
moves east and a warm front approaches from the south. The warm
front likely moves north later Friday. Gusty winds are expected
Thursday night through Friday as deep low pressure passes to the
west of the local waters.

Rough seas Tuesday will subside Wednesday into Thursday. In general,
tranquil conditions are anticipated during the mid week period. Seas
build once again Thursday night and Friday due to increasing
winds.

Hydrology
Less than .25" western locations of additional rainfall is
expected, with 0.50-1.0" east. There is a low chance of minor
nuisance poor drainage flooding through this evening as a
result.

The next chance for significant rainfall of at least a half an inch
is expected to occur late in the week (Thursday night-Friday). Still
too early to determine if there will be any hydrologic concerns with
this potential late week event.

Equipment
Nyc central park winds are out of service until further notice.

Loss of data is due to a severed cable. Parts are on order.

Nyc NOAA weather radio station kwo35 (162.55 mhz) will remain off
the air for an extended period of time.
