Synopsis
Low pressure develops along the mid atlantic coast tonight and
then passes near or just east of long island on Wednesday before
moving up the coast into the canadian maritimes Wednesday
night. High pressure will then build to the south through Friday
and move into the western atlantic this weekend. A cold front
then passes through Monday night into Tuesday morning.

Near term until 6 am Wednesday morning
Light snow continues across NW portions of orange county. Radar
returns are very light and accumulations have been slow through
the day with a report in greenville just under an inch. The
steadier precipitation develops after midnight across the
region.

The forecast largely remains on track. The latest 18z models as
well as the latest hrrr and hrrrx support the ongoing forecast
for tonight into Wednesday morning so no major changes have been
made. The biggest challenge continues to lie with the northward
extent of the warmer air and how far the rain snow line works.

Right now, it appears that it should remain all snow just north
of hpn and dxr, and about 10 to 20 miles to the north and west
of the i-95 corridor in new jersey.

A prolonged period of SE winds in the low levels ahead of the
developing low off the mid atlantic coat tonight will gradually
increase temperatures in the boundary layer. This warming
appears to be sufficient enough for primarily a rain event along
the immediate coast. At the same time, interior sections of the
lower hudson valley and southwest connecticut will be the
recipients of a moderate snowfall event with amounts around
warning criteria. No changes made to the winter weather
headlines from the previous update.

An amplifying upper trough moving across the ohio valley
tonight will allow for the forcing to shift to the mid atlantic
coast tonight, with low pressure developing and tracking
northeast to near or just southeast of long island in the
morning. The transition of energy is slow enough that an
inverted trough to the NW of the low track, extending back into
the hudson valley of new york, will allow for an influx of
warmer air ahead of the low.

Temperatures will remain nearly steady overnight and even slowly
rise. Lows will range from the upper 20s in the interior to the
mid 30s along the coast.

Short term 6 am Wednesday morning through Wednesday night
Low pressure near long island in the morning lifts northeast
during the day and up into the canadian maritimes by Wednesday
night. Precipitation shuts down across most of the area by late
morning early afternoon and perhaps ends as period of snow at
the coast. Even if the changeover to snow occurs a bit faster
than indicated in the city at the coast, limited duration of
precipitation on the backside of the low will limit any
accumulation. Highs will top out in the mid to upper 30s with
nw winds developing on the backside of the storm. Gust up to 20
mph develop late in the day and possibly linger into first half
of the night.

Cold air will follow for Wednesday night with lows in the teens
inland and around 20 at the coast. This is slightly below
normal.

Long term Thursday through Tuesday
Surface high pressure will build to our south on Thursday and
Friday. Meanwhile, an upper trough shifts through with some
shortwave energy Thursday night into Friday. Moisture looks
insufficient for any pcpn, so dry weather is expected. Highs a few
degrees below normal for Thursday, returning to near normal on
Friday. Ridging aloft will then keep the weekend dry with warming
temperatures.

Low pressure enters the great lakes region Sunday night, eventually
tracking through quebec on Tuesday. Some warm advection pcpn may
reach some of the northern zones Sunday night into Monday morning,
which could be in the form of a wintry mix. A cold front otherwise
approaches with increasing chances of rain during the afternoon and
night. Some timing differences still exist among the global models
with the cold front passage, so have capped pops at chance through
Tuesday morning. Rain chances otherwise diminish Tuesday afternoon
with dry weather likely returning Tuesday night. Temperatures Sunday
through Tuesday will remain above normal.

Aviation 00z Wednesday through Sunday
A developing coastal low with move north towards the region
overnight, tracking just southeast of long island on Wednesday,
and then into the canadian maritimes by Wednesday evening.

Conditions expected to gradually lower to MVFR this evening, then
lower to ifr late tonight as precipitation develops across region.

Expect all snow at kswf, which may be moderate at times between
06z and 12z. Rain expected to develop for nyc nj terminals after
midnight, likely mixing with snow towards daybreak, and then
briefly changing to all snow Wed morning. Khpn kbdr may see a
mix of rain snow overnight, before changing to all snow towards
daybreak. All rain expected to for kisp kgon. Precip taper off
from W to E Wed morning into early afternoon, with conditions
improving toVFR.

E NE winds less than 10 kt overnight, becoming N nnw towards
daybreak. Winds become wnw with gusts 20 to 25 kt Wed afternoon
continuing into eve push, likely averaging just right of 310
magnetic.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
