6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

A slow moving cold front will approach from the west, move
through overnight, and stall to the south on Thursday. A wave of
low pressure will then move across on Friday, followed by a
brief respite on Saturday before a more significant frontal
system moves across on Sunday. High pressure will follow for
Monday through Wednesday.
Near term until 6 am Thursday morning
No major changes to the forecast. The cold front is slowly
progressing southeastward and will allow temperatures to
gradually return closer to normal tonight.
Preliminarily, record highs have been reached at nearly all of
our climatological sites. Kisp has a previous record of 63
degrees achieved in 2002, but due to earlier fog and stratus has
been slower to rise compared to sites farther west. It is
possible that the temperature could still rise further over the
next few hours, placing the record in jeopardy.
New record event reports (rer) have been issued as of 430-450
pm. Notably, the 78 degrees at central park is preliminarily the
highest temperature recorded in february, breaking the previous
record of 75 set on february 24, 1985. Similarly, la guardia
has preliminarily broken a monthly record with a temperature
today of 78 degrees, breaking the previous record of 74 set on
february 15, 1949. Newark reached a high of 80 degrees,
preliminarily breaking the previous monthly record of 76 on
february 15, 1949.
Temperatures are still fluctuating, so these aforementioned
records are still subject to change the next few hours. Truly an
incredible pattern overall, more reminiscent of august with a
strong subtropical high pressure. 850 mb temperatures for this
morning's 12z sounding smashed previous records for this time of
year, and are closer to the 90th percentile values for a typical
summer pattern. 500 mb temperatures appear to be record values
as well, and closer to the 90th percentile values summer around
-10.5 degrees. Furthermore, per naefs ensemble archives, the ridge
is of record heights at all levels for this time of year.
The summer-like pattern will abruptly come to an end this
evening into the overnight hours as a cold front moves northwest
to southeast across the area. The line of showers will weaken as
it approaches the strong ridge, then sag and stall to the south
of the area Thursday morning. Temperatures will return to near
normal values behind the front - generally in the 30s to 40s.
Short term 6 am Thursday morning through Thursday night
A wave will move along the stalled frontal boundary, setting up a
period of precipitation from late Thursday morning into Thursday|
evening. With the surface high building southeastward, colder
air will settle into the area, though aloft temperatures will
remain somewhat warm in the 800 mb to 700 mb layer. For most
locations, the precipitation type will be a cold rain, however
for interior areas north and west of nyc there is potential for
a wintry mix of sleet, freezing rain and snow around the evening
commute. These areas will need to be monitored for the
possibility of a winter weather advisory.
As colder air filters into the region, afternoon temperatures
will be 20 to 30 degrees colder than Wednesday. Daytime highs in
the lower to mid 40s will likely occur in the morning, with
temperatures falling into the 30s in the afternoon.
Temperatures on Thursday night will be a few degrees above
normal, in the upper 20s to lower 30s.
Long term Friday through Wednesday
With strong high pressure passing to the north and resulting
cold air damming in place, also warmer air surging in aloft,
there could be some sleet and or freezing rain Fri morning as
the next in a series of waves of low pressure rides atop the
anomalously strong upper ridge to the south. There could be a
brief respite from precip on Saturday as this wave passes east
and weak high pressure passes to the north, with skies clearing
for a time across southern ct as drier air filters in.
Rain chances should again increase Sat night into Sunday with
the approach of a warm front in advance of low pressure moving
from the plains toward the upper great lakes. An associated
trailing cold front should then move through Sunday night,
followed by fair and slightly cooler wx Mon through Wed as
high pressure builds in.
Temps look to be above normal through the period, warmest during
the weekend with the approach of the warm front.
Aviation 00z Thursday through Monday
A cold front moves across the area this evening. A weak area of
low pressure tracks south of the area Thursday.
Winds shift to the NW between 01z and 03z. Brief gusts 25-30 kt
possible with frontal passage. Otherwise, gusts 15 to 20 kt for
nyc nj terminals through around 06z in its wake.
Vfr through Thursday morning, with the potential for some
pockets of MVFR CIGS tonight. Deteriorating conds to MVFR ifr
during the late morning early afternoon Thursday. Wintry mix
likely for swf, spreading south towards kbdr khpn by late
afternoon. Nyc nj and LI terminals should be mainly rain, but
can't rule out some ip mixing in late afternoon evening.

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.
