Synopsis
A warm front approaches today, moving across the region late in
the day into this evening, and a cold front follows tonight, as
the associated low moves across southeastern canada. The low
moves off the NW england coast Friday as high pressure builds
to the west of the region. High pressure builds over the region
into Saturday afternoon with a weak cold front bringing showers
Saturday night into early Sunday. High pressure returns for
memorial day followed by a warm front Tuesday.

Near term through tonight
Widely scattered shower activity at most with isolated thunder is
forecast through early this afternoon. Probabilities will lower
for a few hours into early this afternoon as the vort moves
east. However, with forcing along the warm frontal boundary will
keep slight chance and chance probabilities into this
afternoon.

A greater coverage of showers and thunderstorms occurs along a
pre-frontal trough mid to late this afternoon which mesoscale
models are showing as a line of convection. This will be in
response to greater daytime heating which will increase the
instability especially across the interior, leading to higher
pops when taken in combination with convergence along the pre-
frontal trough.

Then there will be the potential for additional showers and
thunderstorms into early this evening as a more significant
shortwave and energy in the northern stream move into the ridge.

Mesoscale models are depicting this as a second line and one
that would be associated with the cold front boundary. This
will cause falling height through 06z Friday. There will be
destabilization as the area becomes warm sectored once the warm
front moves east of the area, as a weak thermal ridge sets up
across new jersey and into the lower hudson valley. Surface
based instability will increase, however, CAPE will be limited,
and will be mostly elevated. Weak capping will also be present.

There is some timing differences as to when the best elevated
cape and lift move across the region with the NAM a little
later. Scattered convection is possible and a stronger to
locally severe storm can not be ruled out, especially across the
interior where the best dynamics will be. And the best timing
will be 21z to 03z. The main threat will be damaging winds and
hail. Locally moderate to heavy rainfall will also be possible.

Have continues to mentioned the strong to locally severe threat
in the hwo.

The precipitation will be quickly ending after 03z as the
shortwave pushes east bringing cold air into the region from
the north and west. The cold front is forecast to move southeast
of long island overnight.

Short term Friday
Height will be rising through Friday and the eastern sub
tropical ridge builds back into the region once the shortwave
moves east. Cold advection and low level winds of 30 to 35 kts
will result in gusty winds across the area. Cold advection
weakens and becomes weak warm advection 18z to 21z Friday as
the ridge builds, and wind gusts will then begin to subside.

Long term Friday night through Wednesday
High pressure builds from the great lakes Friday night before
sliding offshore late Saturday. This will lead to dry weather
and mild temperatures through Saturday. Lows Friday night will
be in the 50s.

With the high just to the south on Saturday high temperatures
will rise into the 70s, with cooler temperatures along the
coast. Southerly flow will advect in higher dew points, but in
general will be a nice afternoon with some increasing clouds
later in the day.

A weak cold front will approach Saturday night into Sunday.

This could bring a period of showers into early Sunday before
the front pushes offshore by Sunday afternoon.

Heights then rise behind the shortwave that drives the front
east with a ridge building behind for memorial day. That ridge
then becomes quite anomalous with a significant warming trend
likely into mid-week.

An approaching warm front may bring showers Tuesday followed by
dry weather Wednesday and another system on Thursday.

Aviation 15z Thursday through Monday
A warm frontal passage late today will be followed quickly by a
cold frontal passage tonight.

Showers and isolated thunderstorms will gradually dissipate over
the next few hours. Additional showers and thunderstorms are
possible with the warm front this afternoon and evening, and
ahead of the cold front tonight. Any of these will be capable
of producing MVFR or lower conditions.VFR conditions are
expected on Friday.

South winds will increase thru the day today, then become
westerly behind the cold front tonight and remain gusty. Nw
winds will gust to around 30 kt on fri.

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.
