What's New / NOTES
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.

Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. A broad surface high will build into much of the eastern u.s. Late this week before moving offshore this weekend. A strong surface low will develop in the central plains this weekend, lifting northeast into southeast canada early next week. This will bring a strong cold front through the area Monday night and Tuesday. High pressure will build back into the region during the middle of next week.

Synopsis
A broad surface high will build into much of the eastern u.S.

Late this week before moving offshore this weekend. A strong
surface low will develop in the central plains this weekend,
lifting northeast into southeast canada early next week. This
will bring a strong cold front through the area Monday night and
Tuesday. High pressure will build back into the region during
the middle of next week.

Near term until 6 am this morning
With clear skies and light winds, many areas away from the
urban corridor along i-95 are radiating well, and temperatures
are falling off. Will make adjustments to hourly grids based on
latest surface obs, and will end up lowering overnight lows by
several degrees, especially in northern nj and the pine barrens
of nj.

Short term 6 am this morning through 6 pm Saturday
A modest warming trend is expected Friday as the 1000 to 500 mb
thickness increase. Pressure gradient will be rather weak
tomorrow with the high to our south. Consequently winds should
be light (10 mph or less) through the day.

Long term Saturday night through Thursday
A warm and dry weekend followed by an inclement start to the new
week...

model solutions remain rather stable through Tuesday of next
week, with the midlevels featuring generally zonal flow through
the weekend followed by some ridging downstream of a negatively
tilted trough moving through the midwest great lakes late this
weekend into early next week. The trough passes the region
Tuesday and Tuesday night, with reinforcing perturbations in
transient northwest flow Wednesday. Model discrepancies become
large by this time, as phase differences among the ecmwf, gfs,
and cmc become pronounced. However, in terms of sensible
weather, think the Tuesday night through Wednesday night period
should be dry before uncertainty becomes high enough at the end
of the long term for at least mentionable (slight chance) pops.

Not much to discuss sensible-weather wise this weekend, as a
strong surface high in the southeast moves offshore. Statistical
guidance remains consistent in bringing temperatures near or
slightly above 50 for the philadelphia metropolitan area this
weekend but remain muted in warming it up much more than this.

Given the stubborn zonal flow (i.E., lack of increased
amplification downstream of the developing trough in the central
u.S.) depicted, the plateau of temperatures around 10 to 15
degrees above average Saturday through Monday makes sense,
though I do wonder if models are underdoing the amplification
somewhat. As such, I kept things close to MOS guidance, but did
bump maximum temperatures a degree or two during this period.

Isentropic ascent downstream of the negatively-tilted trough on
Monday may lead to warm-advection precipitation in the northern
mid-atlantic and northeast, which required keeping increasing
pops Sunday night and Monday, especially north of the mason-
dixon line. Such regimes tend to be favorable for freezing rain
or sleet (i.E., a low-level warm nose), and did retain mention
of this in the far northern CWA Sunday night and Monday morning.

As the strong cyclone in the plains moves northeast into the
great lakes and southeast canada Monday night and Tuesday, a
strong cold front will sweep through the mid-atlantic during
this period. Models continue to show decent QPF in vicinity of
the front, with some disagreement on timing (gfs fast; ecmwf
slow; cmc in between). Timing continues to favor Monday night,
though it has slowed in the past couple of days to include
Tuesday morning (and perhaps most of the day in the
northern eastern cwa). Given the strong consistent agreement
among models Monday night, introduced categorical pops during
this period and increased pops a little bit through the day
Tuesday. Precipitation may be showery, especially close to the
front, but large-scale lift will be pronounced, suggesting a
more widespread rain may occur. Should showers convection
develop, QPF may be locally enhanced, and this will need to be
watched as the event approaches. A rumble of thunder cannot be
ruled out either, given cold midlevels with the approaching
trough, though this threat looks too low for mention at this
time.

There are some indications of upstream perturbations moving
through the transient northwest flow Tuesday night and
Wednesday, which may lead to flurries or snow showers in the
poconos, but the signal is not agreed upon amongst the
operational models. Kept Tuesday night through Wednesday night
dry as a result, but temperatures will fall back to seasonal
averages as colder high pressure builds into the area.

The 12z ECMWF keeps the high entrenched in the mid-atlantic
through Thursday, but the 12z cmc is quick to bring a developing
low through the area late in the long term (with some indication
of this in the GFS as well, though pushed off to our southeast).

Will add slight chance pops for Thursday at this time, though
this may be on the fast aggressive side.

Friday...VFR. Skc few250. W-sw winds less than 10 kt.

Outlook...

Thursday night through Sunday... PrimarilyVFR, though
increasing clouds should occur Sunday. Winds generally west
around or below 10 kts. High confidence.

Sunday night and Monday... Sub-vfr conditions possible with
increasing chances of rain or showers during the period.

Generally light and variable winds becoming south or southeast
around or below 10 kts. Low confidence.

Monday night and Tuesday... Periods of sub-vfr likely with a good
chance of rain showers, especially through Tuesday morning.

Southeast winds becoming west or southwest after frontal passage

confidence.

Marine
Sub-sca conditions tonight through Friday. Gusts to 20 kt
possible for nj coastal waters in the afternoon.

criteria through Friday.

Outlook...

Friday night through Saturday night: marginal advisory
conditions may occur off the northern central nj coast;
otherwise, sub-advisory conditions and fair weather expected.

Sunday through Monday: sub-advisory conditions, with an
increasing chance of rain or showers by Monday.

Monday night and Tuesday: advisory-level winds possible (south
or southeast before frontal passage; west after frontal passage),
with a good chance of rain or showers.
