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.

Offshore high pressure today will eventually give way to
approaching low pressure from the south. The low continues to
move closer to the region tonight into Wednesday and eventually
the low center moves right across the area Wednesday night. Low
pressure lifts to the north on Thursday. High pressure briefly
builds, then gives way to a wave of low pressure late Friday and
Friday night. A cold front moves through Saturday followed by
high pressure Sunday and Monday.

Near term until 6 pm this evening
The upper level jet stays north of the region with some upper
level ridging. The surface high pressure will remain offshore
and slowly move farther offshore during today. There will be
some Sun for the first half of the day but clouds will increase,
lower and thicken during the afternoon. The pressure gradient
will remain weak, keeping the onshore flow weak. Therefore used
a warmer blend for temperatures with the ecs mav guidance.

Expecting another day in the lower 60s near the coast and more
in the mid to upper 60s away from the coast.

Short term 6 pm this evening through Wednesday night
Surface low pressure slowly approaches from the southeast us.

There will be multiple trough approaching from the west in the
upper levels and even some signs of phasing between the northern
and southern branches of the upper jet. Expect most rain tonight
through Wednesday with it tapering off Wednesday night as the
low moves overhead Wednesday night and eventually north of the
region late Wednesday night.

Most substantial increase in isentropic lift occurs right after
00z wed. Most rain falls Tue night through Wed morning with a
max of omega conveyed by models around the 12z hour. This will
also coincide with the approach of the southerly low level jet.

Nam is remarkably farther west with this compared to the GFS and
other models such as the canadian and ecmwf. Depth of lift as
diagnosed by omega decreases Wednesday afternoon. Steady rain
will become lighter and may have some breaks from time to time.

Thunderstorm potential will be isolated due to presence of some
low level instability off the atlantic feed of moisture. Also
related to the atlantic feed of moisture will be the
precipitable waters, which are forecast to reach 1 to 1.3 inches
Wednesday morning into early Wednesday afternoon. After that,
the precipitable waters decrease, with values closer to 1 inch
through the evening. Further drop of precipitable water to
below half inch by early Thursday.

Ample low level moisture will be present as well Wednesday into
Wednesday evening. The steadier rainfall during the day will be
accompanied by fog but kept coverage patchy. There will be a
period of time Wednesday evening with the center of the low
passing overhead. The less forcing will make for lighter rain
and light winds will keep moisture abundant considering the
earlier rainfall. Expecting areas of fog to develop Wednesday
evening and then become more patchy overnight when winds become
more westerly behind the low.

Used a consensus of raw temperatures for the short term and to
minimize diurnal temperature ranges.

Long term Thursday through Monday
During the Thursday through Saturday time frame, features to watch
include departing shortwave over the northeast, southern stream
shortwave traversing across the southeast states ahead of vigorous
northern stream shortwave that moves out of the upper midwest toward
the east coast by Saturday.

The southern stream shortwave will lift northeast as the downstream
trough amplifies, with deep SW flow setting up. During the late
Friday time frame, showers ahead of this shortwave and sfc low are
possible, but differences in the models continue, with non gfs
solutions pushing most of the precip just SE of the area. Will
maintain chance pops with higher probabilities SE zones due to the

Prior to that, generally dry weather is expected Thursday, Thursday
night and into early Friday. Any lingering rain ends Thursday

During the Saturday night through Monday timeframe, upper trough
pushes east, and there is the potential for additional showers late
Saturday into Saturday night, although probabilities do not appear
to be high at this time. Greater likelihood would be NW of the area
as trough closes off north of the great lakes region.

Upper trough lingers Sunday but gives way to building ridge as sfc
high builds by Monday.

Temperatures remain right around seasonal norms, with Sunday perhaps
a few degrees cooler behind the cold front. Temperatures warm early
next week.

Aviation 12z Tuesday through Saturday
High pres will continue to move off the coast today. Low pres
approaches from the SW tngt.

Light and vrb flow this mrng. Flow becomes sely aft 14z, then backs
to the ese aft 18z, and to the E aft 00z. Speeds generally around
10kt or less until aft 00z, then a gradual increase can be expected,
especially at the coasts. Gusts to around 20kt on wed.

Vfr through 00z, with cond lowering to ifr or lower overnight as
rain develops. There is a low chc for tstms aft 12z wed.

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.
