401 am edt Thu sep 20 2018
High pressure will build down from the canadian maritimes through
Friday morning, then weaken Friday afternoon ahead of an
approaching cold front. The front will move across Friday night
into Saturday morning, settling to the south into early next week
as strong high pressure builds to the north. A slow moving frontal
system will approach during the middle of next week.
Near term until 6 pm this evening
Scattered showers generated in area of blyr moisture
convergence sfc theta-e ridging, with additional lift via
passing weak mid level shortwave trough, have shifted out of the
nyc metro area west into north central nj and just outside our
area. As the sfc high builds SW this area will continue to shift
away from our area, with mostly sunny skies developing this
afternoon. High temps are a blend of GFS nam MOS guidance, with
all but the highest elevations reaching the lower 70s.
Short term 6 pm this evening through 6 pm Friday
As a warm front passes to the north Thu night into Fri morning,
skies should become mostly cloudy, with a shower or two
possible well NW of nyc. Skies should remain mostly cloudy well
nw into Fri afternoon well in advance of a cold front as
moisture remains trapped beneath a low level inversion, with
partly cloudy skies east. S winds should increase, and also
become gusty Fri afternoon, with a sea breeze enhanced by
synoptic-scale flow, and perhaps some stronger gusts than fcst
especially NW of nyc Fri afternoon, depending on the strength of
the inversion. If on the weaker side, areas NW of nyc could see
gusts 25-30 kt well in advance of the approaching cold front.
High temps on Fri should be 70-75, which is close to average.
A moderate rip current risk exists through Thursday.
Long term Friday night through Wednesday
A zonal flow will generally prevail through the weekend, with
the h5 flow amplifying across north america early next week.
Differences in timing and amplitude with the digging western
trough and eastern ridging remain through the middle of next
Cold front moves across the area Fri night accompanied by
showers and tstms. There is a low chance that strong upstream
convection could produce strong damaging winds in areas NW of
nyc, but do not have a lot of confidence in this attm. The
convective line forecast to develop over western ny pa during
the day Fri is expected weaken as it approaches and moves across
the local area into a more stable environment during the late
evening and overnight hours.
Thereafter, a fall type air mass is likely for this weekend and
into early next week as the cold front settles to the south and
canadian high pressure builds into new england. With close
proximity to stalled boundary and under periphery of the
ridge upper jet, could be looking at mid and high clouds
streaming across through the weekend. A few sprinkles or light
showers may still possible across nyc metro and long island if
the boundary stalls close enough. Then a gradually increasing
chance for stratus and shower development Monday night with
approach of the next frontal system.
There is a good signal for a return to a moist tropical
environment for the middle of the week as deep trough amplifies
into the central states, and bermuda ridging holds strong. A
slow-moving frontal system will bring potential for rounds of|
showers and thunderstorms, particularly across the interior,
during this time along with a warm and unseasonably humid
Aviation 07z Thursday through Monday
High pressure remains over the region.
Areas of MVFR improving toVFR all arpts by 12z-14z. Stratus
will redevelop again tngt with CIGS around 2000 ft expected.
Winds becoming NE or vrb thru 10z, then veering to the SE thru
the day, and remaining SE tngt.
Outlook for 06z Thursday through Monday
Tonight Slight chance of light rain with MVFR likely.
Friday-Friday night Vfr during the day, then a chance of
showers and thunderstorms with MVFR at night.
Saturday-Sunday An early shower Saturday, thenVFR through
Monday Chance of MVFR especially in the afternoon.
Sca remains in effect for the ocean today, seas 4-6 ft today and
running about 1 ft above guidance. It is questionable whether
5-ft seas could linger into this evening, so SCA not extended
into that time frame.
Increasing s-sw flow ahead of an approaching cold front should
produce SCA conds on most of the local waters late Fri fri
night. Winds should diminish by Sat morning, although SCA swells
on the ocean will likely linger into Saturday morning.
Sub advy conditions are then expected on all waters through the
remainder of the weekend as high pressure builds to the north.
Easterly winds likely strengthen Monday into Monday night ahead
of an approaching warm front, with potential for SCA conditions
to develop on the ocean.
No significant hydrologic impacts expected through tue. There
is potential for rounds of heavy showers and thunderstorms mid
to late next week.
Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air for an extended period of time.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
