Synopsis
High pressure builds in from the west through tonight, before
retreating into new england Thursday. An area of low pressure
will develop over the tennessee valley Thursday, with a second
area of low pressure moving up the east coast Thursday night.

The low will likely pass just east of montauk early Friday,
then into the canadian maritimes Friday night. A broad area of
high pressure builds in for the weekend.

Near term through tonight
High pressure continues its track east toward the region. Mostly
clear skies persist this afternoon and evening with
gusty northwest winds, gusting to 20-30 kts. Winds relax this
evening tonight as the pressure gradient decreases. Temperatures
around the region curretnly sit in the upper 30s-low 40s and
aren't expected to increase much more.

Short term Thursday through Thursday night
High shifts towards new england tonight with a continuation of
dry weather. Temperatures will continue to be seasonably cold
with low temperatures tonight in the teens across the northern
suburbs and the pine barrens and low to mid 20s elsewhere. A
freeze warning is in effect for the remaining boroughs where the
growing season has not yet ended. A strengthening low pressure
then rapidly moves northeast up the coast on Thursday with
precipitation developing across the area. A wintry mix is
expected initially, with probably a change over to rain along
the coast around sunset. Temperatures on Thursday will be in the
low 30s inland and mid to upper 30s to near 40 along the coast.

Long term Friday through Tuesday
Overall timing of the storm is a bit faster than 24 hours ago, with
good clustering of the low INVOF long island at 12z fri. The low is
then over the gulf of me by 18z.

The increased speed puts Thu eve under the gun for the worst of the
wintry pcpn. Mainly snow or a snow sleet mix can be expected across
the interior during this time, with the coasts transitioning to
rain. By late in the eve overnight, a transition to fzra should
occur over the interior and much of the remaining area will go to
all rain. Ice accretion has been ramped up significantly in the
fcst, to around a quarter inch in the hudson valley where the
predominant ely flow will likely remain backed further to the n.

For snow, a solid burst of mdt to hvy snow appears likely with the
initial surge of waa. Advy lvl snow has been included in the fcst
away from the coasts.

Wind will increase Thu ngt as the gradient tightens ahead of the
low. Strongest flow along the coasts, particularly ERN long island
aft the development and passage of a cstl front. 40 mph gusts
possible in this zone. As the low makes its closes approach possibly
over li, winds across the region would then weaken, before ramping
up again as the low pulls away. Winds on the back side could
approach 50 mph, again mainly ERN coasts, if the more intense nam
verifies.

The pcpn winds down fri, then fair wx is fcst thru sat. Low chcs for
pcpn on Sun thru Mon with a frontal sys potentially impacting the
area. There remain some significant timing and track differences
between the GFS and ecmwf, so a blended approach was used for the
fcst. The model consensus was for dry wx on tue.

Aviation 18z Wednesday through Monday
High pressure builds in from the west through tonight, before
retreating into new england Thursday. Low pressure approaches the
region Thursday night and heads to the maritimes Friday.

Vfr through Thursday morning. NW winds gusting to 20-25 kt subside
21z-23z, then veer to N and NE overnight. Conditions lower to MVFR
as light snow overspreads the region 18z-20z Thursday, then to ifr
or perhaps lifr in a burst of heavier snow 20z-22z. Winds become
e NE 10-15 kt with some gusts to 20-25 kt along coast late in the
day.

Expect quick change to rain across nyc, long island, and southern ct
terminals 22z Thu to 00z fri, then across the lower hudson valley
terminals between 00z and 02z Friday. Rain continues Thursday night
with NE winds 15-25 kt and gusts of 20-30 kt, mainly near coast,
becoming N overnight.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
