Synopsis
Low pressure will pass to our south and east overnight. High
pressure on Monday will then give way to a cold front and wave
of low pressure Tuesday and Tuesday night. High pressure will
follow for Wednesday and Thursday, then another cold front will
pass through on Friday. High pressure on Saturday and early
Sunday should give way to another low pressure system later
Sunday.

Near term until 6 am this morning
Low pressure will continue to pass to the south and east of long
island overnight. Intermittent light rain will also continue to
dissipate from west to east with dry conditions anticipated
area wide after 09z.

Lingering low level moisture may produce patchy fog across the
interior. Will need to monitor for dense fog development, but at
this time do not think this will occur.

Overnight lows will range from around 40 far north and west to
around 50 across new york city and long island where clouds will
linger the longest.

Short term 6 am this morning through 6 pm Tuesday
Dry on Monday as high pressure builds across. Low clouds during
the morning should break allowing for a mostly sunny day. Winds
should be light with the high overhead. Temperatures on Monday
will be in the lower mid 60s. Overnight lows Mon night will be
in the lower mid 40s inland, and upper 40s lower 50s along the
coast.

Long term Tuesday night through Sunday
On Tuesday, expecting no more than light rain at most for ct and
long island, where low level ridging and mid level dry air (if
not low level as sfc winds will be off the atlantic) should hold
longer, and a steadier rain NW of there, mainly in the afternoon
as a frontal system approaches.

Better dynamics aloft with the approaching mid level trough
have trended far enough south for Tue night that a wave of low
pressure now looks likely to develop along the approaching front.

Resulting enhanced lift and destabilization, with fcst soundings
showing elevated CAPE and k tt indices near 30 50 respectively,
suggest elevated thunder across long island southern ct mainly
overnight.

High pressure should dominate through fri, with a cold frontal
approach daytime Fri and passage Fri night that could bring a
chance of showers mainly inland. Siding more with ECMWF longer
term, with sfc high pressure Sat into Sunday morning, then
increasing chances of rain through the day on Sunday.

Temps should be near normal with cloud cover and rain on tue,
then above normal by at least several degrees wed-fri. Slightly
cooler than normal temps likely after cold FROPA for next
weekend.

Aviation 06z Monday through Friday
High pressure builds into the region today.

Mostly MVFR to start, then improving toVFR across the
terminals as the morning push progresses. RemainingVFR into the
evening.

Ne-n winds averaging around 10kt. Some gusts 15-20kt will be
possible mainly for klga kjfk kisp kbdr kgon and mainly during
the morning hours. Winds veer more ene late aftn early eve.

Outlook for 06z Tuesday through Friday
Monday night MVFR towards daybreak.

Tuesday MVFR ifr. Sct -shra daytime then rain at night.

Wednesday-Thursday Vfr. Chc W gusts 20-25kt on weds.

Friday Chc MVFR and rain pm.

sca is in effect for the ocean for tonight and Monday. As for the
non-ocean waters, there could be occasional gusts to 25 kt late
tonight into early Monday morning for eastern LI sound and the
eastern bays.

Elevated ocean seas likely to persist into daytime Wed if not
wed evening. Should also see wind gusts over 25 kt on the ocean
daytime Wed after a cold front and wave of low pressure pass.

Minimal SCA conds may be possible very long term (fri night)
after another cold frontal passage.S

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.
