Synopsis
Low pressure passes to the north of the area, with a trailing
cold front also passing through. The low will move into new
england today. Another low will move through on Friday,
followed by a cold frontal passage late Saturday. High pressure
will then be in control early to mid next week.

Near term until 6 am this morning
Scattered shower coverage noted on radar, and coverage should
decrease early this morning before ending by 6 am.

Areas of fog will scour out as winds turn toward the west behind
the low and front. Fcst low temps tonight are on the warmer
side of the MOS envelope, in the upper 40s and lower 50s.

Short term 6 am this morning through 6 pm Friday
Gusty wnw flow expected along with mostly sunny skies for the
most part after the mid level shortwave passes through. A closed
mid level low passing just to the north may help provide enough
lift for sct-bkn CU development in the afternoon, more so
inland.

With downslope flow and mixing to between 875-850 mb expect
high temps to approach 70 in NE nj and rise well into the 60s
most elsewhere.

Thu night should start mostly clear, then become mostly cloudy
overnight as another low begins to approach from the sw. Low
temps should be in the 40s and lower 50s per MOS blend.

Long term Friday night through Wednesday
Models in good agreement with the closed low over the central
plains tracking eastward through the deep south on Thursday.

This then lifts north toward the region Friday ahead of the next
northern stream trough digging into the mississippi river
valley on Thursday. At the surface, associated low pressure
lifts northeast towards the region on Friday. This is a
progressive system, with what looks like a quick hit of moderate
rain (1 4 to 3 4 inch, locally 1 inch). Still uncertainty on
where the axis of the heaviest rain will be, due to differences
in track of low pressure and consequently placement of best
lift instability axis.

Models then in general agreement with partial phasing of the
southern energy and digging northern stream trough to develop
a deep trough over the great lakes into the NE us this weekend.

Some spread in intensity amplitude of this trough, but general
consensus on its axis moving through Sunday. At the surface, an
associated cold front moves through late Sat sat evening, with a
couple of weak troughs moving through Sunday. Seasonable temps
on Saturday in WAA ahead of the front, dropping back down to a
few degrees below seasonable on Sunday with cold pool and
instability cloud cover.

In its wake, deep layered ridging builds in for early next week,
with potential for unseasonable warmth by midweek as ridging
takes a bermuda position. Temps moderate to seasonable on Monday
and then above seasonable on Tuesday. Potential for the first
real warm spell of the season mid to late week, with high temps
in the 80s for nyc nj metro and interior, and well into the 70s
along the coast.

Aviation 06z Thursday through Monday
A cold front passes through this morning with low pressure
tracking to the canadian maritimes by Thursday evening.

Ifr or less through at least 08z. Light rain drizzle continues
through then, with some pockets of moderate rain possible.

Outside of times when areas receive moderate rain, expect
widespread vlifr fog across most, if not all terminals except
kswf. Conditions should improve to MVFR 8-11z from W to e, then
toVFR from 10-13z from W to E as well.

Light and variable winds become w-wnw 8-11z from W to e. Wind
speeds increase to 10-15kt during the morning push, with gusts
of 15-20kt developing towards the end of the morning push. Winds
back to the wsw-sw at kjfk and kisp Thursday afternoon,
remaining W to wnw elsewhere. Wind gusts should abate late
Thursday afternoon early Thursday evening.

Outlook for 06z Friday through Monday
Thursday night Vfr.

Friday MVFR or lower possible in rain.

Friday night-Saturday night MVFR possible in isolated-
scattered showers, otherwiseVFR.

Sunday-Monday Vfr. W-nw winds g15-25kt possible.

Marine
Sca remains in effect for the ocean for elevated seas.

Marine dense fog advy remains in effect for a few more hours.

Cold FROPA will shift winds to the w-nw and quickly scour out
the fog early this morning.

Sca seas likely continue on the ocean waters into Saturday
night, possibly lingering into Sunday, due to lingering se
swells from the mid week system, and then added contribution of
wind waves and southerly swells from a quick moving low on
Friday and winds ahead and behind cold frontal passage Sat eve.

Marginal SCA winds possible, mainly eastern waters Friday
aft eve on the eastern flank of low pressure.

Hydrology
Dry weather returns today.

Qpf 1 4 to 3 4 inch possible Friday with a quick moving low. No
hydrologic issues anticipated.

Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
