731 pm edt Thu jun 22 2017

Synopsis
A warm front approaches tonight and passes Friday. A cold front
moves across Saturday and behind it another cold front will slowly
approach from the north. The second cold front moves in and
weakens early next week. This eventually moves farther northeast
of the region toward the middle of next week with a strong high
pressure area building in from the west thereafter.

Near term until 6 am Friday morning
Minor updates this evening to reflect current temperature and
dew point trends, as well as stronger than forecast winds in the
nyc boroughs. Winds should gradually decrease after dark, with
gusts diminishing. Previous discussion follows.

Warm and increasingly humid conditions will prevail tonight.

Will need to keep an eye on any stratus and fog development,
possibly advecting northward from the ocean later tonight. Long
island and southern ct most likely locales.

Otherwise, weak shortwaves vorts in W SW upper flow, along with
an approaching warm front could trigger a few showers possible
thunderstorms overnight.

With clouds and southerly flow, warm temps overnight expected with
not much disparity across the region. A MOS model blend followed.

There is a moderate risk for the development of rip currents at the
eastern suffolk ocean beaches into this evening.

Short term 6 am Friday morning through Friday night
A series of weak upper level shortwaves vorts could trigger a few
showers thunderstorms Friday as a sfc warm front passes in the
morning. Capes build, with highest values where they typically are,
across the interior away from marine layer. As layer precipitable
water values climb to over 2 inches, will mention heavy rainfall
with any thunderstorms. Instability wanes somewhat Friday night, but
thunder remains a possibility and heavy rain is certainly possible
in any convection. In general, expect scattered to numerous
coverage, but it will not rain all the time.

Warm temps in the 80s during the day can be expected, and 60s to 70
at night, along with high humidity. Again, not much disparity in low
temps is expected due to clouds, southerly winds and high humidity
in place.

Long term Saturday through Thursday
Overall, looking at the large scale, a trough remains in the
northeast this weekend into next week with a pattern change towards
more ridging evident towards the end of next week. The area will
have the jet stream in the vicinity of the region through early next
week. It will be oriented from SW to NE with a MAX speed of roughly
100-120 kt.

At the surface, a cold front will be approaching the region Saturday
and moving across from NW to SE through the day. A weak low develops
along the front with a sharp mid level shortwave aloft. The front
moves farther offshore SE of long island Saturday night. A weak
pressure pattern sets in place thereafter for Sunday and Sunday
night. A cold front approaches and weakens as it moves in early next
week. Eventually, building high pressure well west of the region
starts to build in mid to late next week.

In terms of weather, a wet start to the weekend with showers and a
few thunderstorms Saturday. Instability is lower Saturday so left
thunderstorm coverage as isolated. Showers are likely. Weather
becomes drier from NW to SE during the afternoon with more westerly
flow getting established. Mainly dry conditions are expected
thereafter. There will be mainly diurnally driven low chances for
showers and thunderstorms Sunday through early next week, but expect
majority of the region to remain dry. Temperatures a little above
normal Saturday but otherwise right near normal values for the rest
of the long term period.

Aviation 00z Friday through Tuesday
A warm front approaches the region tngt, and lifts nwd thru the
area fri.

MainlyVFR tngt, however there is a chance that some areas of
MVFR or lower develop. Pockets of MVFR are possible again on
fri with CIGS around 2500 ft. For now the tafs indicateVFR
because coverage is too uncertain attm.

There will be a chance of isold-sct shwrs thru the day, with the
potential for strong tstms aft 20z, particularly in areas along
and W of the hudson river.

Sea breeze flow will lessen overnight, and veer to the SW as the
flow weakens. The sea breeze may attempt to back winds closer to
the S again aft 14z fri.

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.
