Synopsis
A warm front will slowly move north of the area tonight,
followed by a cold front Wednesday and Wednesday night. High
pressure returns on Thursday and then builds to the north on
Friday as a wave of low pressure passes to the south. A stronger
high pressure builds from the west over the weekend and then
offshore early next week.

Near term until 6 pm this evening
The main story today will be the potential for severe
thunderstorms as a cold front approaches from the west. Prior to
its approach, showers and thunderstorms will develop and move
over the area, mainly across long island and connecticut early
this morning. The primary focus for these showers and
thunderstorms is the warm front that is still in the vicinity.

As the warm front lifts north, coverage should decrease until
the cold front approaches later this afternoon. However, the
chance for showers and thunderstorms remains until then.

The cold front will approach this afternoon. Out ahead of the
front, a line of showers and thunderstorms is forecast to
develop. Some of these showers and thunderstorms will be strong,
with gusty winds of 30-40 mph, and possibly severe, with
damaging wind gusts of up to 60 mph. Lifted indices in the -4 to
-6 range support the potential for severe, given the cold front
as the primary lifting mechanism. There will be a decent amount
of instability with MUCAPE values in the 1000-2000 j kg range.

Also associated with these storms will be brief, heavy rainfall.

The rainfall is not expected to be nearly as high as yesterday.

However, southern connecticut has very low one hour flash flood
guidance of 0.25" hr or less thanks to the very heavy rain that
fell yesterday. Despite the fact that the rainfall will be
lower today as compared to yesterday, flash flooding will once
again be possible, mainly for connecticut.

There is a high rip current risk for the atlantic beaches
today.

Short term 6 pm this evening through Thursday night
The threat for severe storms will continue through about
midnight across the tri-state area, until the cold front pushes
off the east coast. Also, the continued threat for flash
flooding for connecticut will continue. Thereafter, chances for
showers and thunderstorms decreases as high pressure builds in
from the northwest.

The cold front will remain just to our south, and a slight
chance for showers may continue across mainly long island for
Thursday. A weak area of low pressure will develop along the
frontal boundary, and unsettled weather will come back into the
picture for Thursday night into Friday.

There is a low rip current risk for the atlantic beaches on
Thursday.

Long term Friday through Tuesday
The low moves offshore into Friday night with a stronger high
building into the region for the rest of the weekend. This high
will likely move offshore early next week with the approach of
the next frontal system.

Temperatures should average near normal through the long term period
with highs in the upper 60s and lower 70s and nighttime
temperatures mainly in the lower and middle 50s.

Aviation 10z Wednesday through Sunday
Warm front will lift north of the terminals this morning, followed
by a cold front this evening and tonight.

Heavy rain showers have re-developed east of nyc. These showers
should linger through the early morning hours, mainly across kisp,
kbdr and kgon. We should then see a break in the precipitation,
before additional showers and thunderstorms return to the region
this afternoon and evening as a cold front approaches and moves
across the area. Some of these storms will be capable of gusty winds
and heavy rain.

Winds will continue to diminish overnight. Light and variable
winds will be likely across the lower hudson valley. S-sw winds
of 10 to 15 kt expected today, then become NW behind the cold
front after 00z tonight.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
