What's New / NOTES
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.
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.

Synopsis
High pressure will be in control through Tuesday, then give way to a
coastal low pressure Tuesday night into Wednesday night. Another low
pressure systems may affect the region Friday or Saturday.

Near term until 6 pm this evening
The forecast is on track with only minor adjustments made to the
hourly forecast for a few elements.

Sunny, tranquil and seasonable spring conditions this afternoon
with surface high pressure building in. Highs 60-65 in most
areas, although temps will likely drop back into the 50s along
the south coasts late this afternoon with sea breezes pushing
through. Parts of NE nj and the city along with some adjacent
areas should have temps rising into the mid 60s.

Short term 6 pm this evening through Tuesday
Trough axis slides offshore tonight, with shortwave ridging building
into the region through Monday night and then offshore on Tuesday.

Meanwhile, an upper low over the southern mississippi river valley
today will slowly works northeast towards the central appalachians
through Tuesday. At the surface, high pressure will build overhead
tonight, and then gradually slide offshore Monday into Tuesday.

Meanwhile, southern low pressure begins to lift NE towards the
mid atlantic on Tuesday.

A clear and chilly night once again tonight. Areas of frost likely
across outlying areas with good radiational cooling to around
freezing. Elsewhere lows generally in lower 40s to mid 40s. A
continued moderation in airmass and moisture Monday night,
should have temps slightly warmer, with a more patchy threat
for frost across far outlying areas.

Mostly sunny, tranquil and seasonable spring conditions continue
Monday. With continued moderation of airmass and developing return
flow, temps across the interior should continue to moderate into the
mid to upper 60s. Meanwhile, along the coast, temps will likely hold
in the lower 60s with onshore flow and early sea breeze development.

Even nyc nj metro will sea breeze in this flow regime, which should
hold temps in the lower to mid 60s.

The influence of offshore high pressure should maintain another dry
day Tuesday. NAM is likely too aggressive with stratus
development during the day, but increasing late
afternoon evening cloud cover seems likely. Despite mostly sunny
conditions to start, greater influence of a canadian maritime
airmass on Tuesday and continued onshore flow should have temps
dropping back to near or slightly below seasonable levels for
much of the region. Lower to mid 60s NW interior, lower 60s
nyc nj metro to upper 50s across coastal areas.

Long term Tuesday night through Saturday
Models continue in good agreement with the southern closed
upper low over the tennessee river valley Tuesday, opening and
lifting into the NE us through Wednesday in response to northern
stream shortwave energy moving into the upper midwest great
lakes. At the surface, resultant low pressure lifts towards the
region Tuesday night into Wednesday, and then into new england
wed night. A soaking rain with breezy E SE winds is expected to
develop across the area Tuesday night and continue into
Wednesday morning. Can't rule out an isolated thunderstorm wed
morning into early afternoon along ahead of warm front with
weak elevated instability and forcing from approaching
shortwave energy and 50-60 kt llj. Best forcing moisture move
ne Wed afternoon, with lingering showers late Wed into Wed eve.

Thereafter, models still have some spread in the evolution of the
above mentioned upper midwest great lakes trough, as its energy
splits N S during the late week period. This is further complicated
by differences in evolution of the next northern stream shortwave
diving into the great lakes and mississippi river valley for late
week. The interaction between these two energies will determine
sensible weather for Fri into the weekend. At this point, it appears
there is potential for one or two progressive low pressure systems
to affect the region during this time, but predictability on details
is low. Will continue with low chance of showers in the forecast
during this time to denote the potential.

As for temperatures, much of the period will feature seasonable
temperatures with the exception of Wednesday, where onshore flow
will keep highs several degrees below normal.

Aviation 18z Sunday through Friday
Vfr conditions through the TAF period with high pressure in control.

Sea breeze has begun to develop, moving across kjfk. The sea breeze
should gradually move inland and pass across kisp and klga this
afternoon. Confidence is lower for kewr and kteb, and winds could
remain NW or W through the remainder of the afternoon with a early
evening sea breeze passage. The sound breeze should pass through
kbdr and kgon 18-19z.

Kswf will remain with NW flow and this is possible across khpn as
well.

Winds become light and variable tonight before becoming SE 5-10 kt
Monday morning and early afternoon.

Outlook for 18z Monday through Friday
Monday afternoon-Tuesday Vfr. SE gusts 20 kt possible near the
coast on Tuesday.

Tuesday night-Wednesday Ifr becoming likely with rain. SE gusts
near 20 kt Tuesday night. E gusts 20 kt on Wednesday morning.

Thursday-Friday MainlyVFR. Chance of showers.

Marine
Sub-sca conditions expected through Tuesday with high pressure in
control and a weak pressure gradient. Although there is
potential for 15 to 20 kt gusts in late day sea breezes across
ny bight and surrounding nearshore waters late this afternoon
and perhaps late Monday afternoon.

Low pressure moving up the eastern seaboard Tuesday into Wednesday
will result in strengthening easterly winds and building seas
Tuesday night, with SCA conditions likely to returning late
Tuesday night into Wednesday morning.

Winds likely subside below SCA late Wed into Wed eve as low
pressure moves over and then NE of the region, but ocean seas
may remain elevated a SCA levels into late week from residual
se swells.

Hydrology
Dry conditions are expected through Tuesday.

A widespread 1 2 to 1 inch of rain is expected Tuesday night
into Wednesday, but no hydrologic issues are anticipated at this
time.

Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air.

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.
