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
Low pressure tracks to south of long island this morning and
will then move to the southeast of CAPE cod this afternoon. The
deepening low then quickly exits into the canadian maritimes
tonight through Friday. High pressure slowly builds in from the
great lakes Friday night through Sunday night, then gradually
slides offshore from Monday through Tuesday night. A coastal low
approaches from the southeastern seaboard on Wednesday.

Near term until 6 pm this evening
The main upper level jet will be south of the region. A
persistent upper level low will remain in the northeast. The mid
levels convey a flattened mid level ridge moving east of the
region with an approaching shortwave trough. At the surface, a
low will be moving to south of long island this morning and then
this low will be tracking to southeast of CAPE cod.

Low level warm air advection has been occurring with some
isentropic lift as well. This will be a setup for overrunning
rain that will be main weather theme of the day. Going into this
morning, higher terrain across the interior could have the
precipitation as a rain snow mix or even some snow. Little to no
snow accumulation is expected, if anyplace gets any
accumulation, it would be the higher terrain where temperatures
will be slightly below freezing.

Expecting a damp cool day as temperatures will not rise much
from early morning values.

Continuous rain expected on a light northerly flow to start but that
flow will increase towards mid to late afternoon as pressure
gradient becomes tighter between the low and strong high pressure
still well out west into the central plains.

Expecting cooler than normal temperature with the northerly flow and
rain through the day. Used the cooler met guidance for highs.

Increased one degree along the coast for highs.

Short term 6 pm this evening through 6 pm Friday
The main upper level jet will remain south of the region through
Friday.

For Thursday night:
two more shortwaves pivot across the region in the mid levels. So
despite the surface low moving farther away to the south of nova
scotia, the region will remain in cyclonic flow aloft. The chances
for precipitation while lower than earlier in the day, will be
still be present mainly during the evening. Cold air advection
on the backside could result in a light rain snow mix across
some parts of the interior, especially higher terrain. No
snow accumulation is expected. Otherwise, the precipitation
will end as rain.

For overnight, more drying takes over with the persistent nw
flow.

With the abundant clouds, used a blend of guidance in terms of
temperatures including the previous forecast. There will be
some cold air advection but without ideal radiational cooling.

Winds stay up so despite temperatures in the mid 30s for those
parts of the region in the growing season, not expecting frost
formation.

For Friday:
in the mid levels, the mid low will be moving east of the region,
allowing for heights to build as ridging commences from well to the
west.

The same pressure gradient remains for Friday so that will mean more
gusty NW flow. At the surface, the low will be moving near
newfoundland while the high will be moving into the great lakes and
into the west of the appalachians.

Nw flow continues so dry conditions will remain. Still expecting
abundant clouds though, so will side with a blend for high
temperatures including the previous forecast.

Long term Friday night through Wednesday
Nw flow aloft Friday night. With no shortwave embedded in the flow
progged to impact the region, have continued with the dry forecast.

Lows Friday night should be around 5-10 degrees below normal.

A couple of northern stream 700-500 hpa shortwaves push through the
area Saturday and Saturday night as the rotate around the base of a
closed low over the canadian maritimes. With relative dry low levels
and downsloping boundary layer flow, the shortwaves should pass
through dry. Highs on Saturday and low Saturday night should be
around 5-10 degrees below normal.

Deep layered ridging then begins to builds in Sunday and continues
to ridge over the area through Tuesday. Subsidence associated with
the ridge should keep things dry and relatively (if not totally)
cloud free during this time frame. Highs Sunday-Tuesday run a few
degrees below normal and lows during this time frame run 5-10
degrees below normal.

Noting that 1) the GFS has a known progressive bias in the long term
and 2) that the upper level pattern features closed lows and fairly
sharp ridges - both of which support a less progressive pattern -
favor the slower lifting of the ridge axis to the NE and arrival of
the next system in the ECMWF cmc global than the more progressive gfs
handling of both features. The forecast Tuesday night-Wednesday is
based on a blend of the ECMWF cmc global as a result.

Tuesday night should be dry as the deep layered ridge axis lifts to
the northeast. Most of Wednesday should probably be dry as well, but
to keep things simple, given the inherent uncertainty this far out,
have run chance pops the entire period for some warm advection
induced rains. Lows Tuesday night should be near to slightly above
normal and highs on Wednesday a few degrees below normal.

Aviation 09z Thursday through Monday
Low pressure passes to the south today.

Vfr bcmg MVFR to locally ifr after around 12z. Ra -shra through
around 12z, then a break until around noon when more rain
probably moves in.VFR returns late aftn.

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.
