What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 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.

Synopsis
High pressure will retreat well offshore tonight. Low pressure
approaches from the southwest early on Saturday with the potential
for showers which will continue into Monday. High pressure then
builds in later Monday, bringing dry conditions into midweek
next week along with a moderating trend in temperatures.

Near term until 6 am Saturday morning
1010 pm update...

updated to adjust temperatures and dew points for current
trends. Otherwise no changes planned.

825 pm update...

forecast is on track as far as low temperatures. Have updated a
few parameters including temperatures, dew points, and winds.

625 pm update...

minor changes to the forecast for current temperature and dew
point adjustments. Cirrus is moving across the region with lower
clouds moving in from the sw.

Previous discussion... Clear skies across the region will
slowly give way to cloud cover overnight as a warm front
advances northwards. With thickening clouds by morning
temperatures will not drop as far as the past few nights with
lows bottoming out in the mid 40s.

Short term 6 am Saturday morning through Saturday night
Low pressure over the ohio valley will move northeast through
the day pushing a warm front through the region. Widespread lift
will result in increasing showers through the afternoon. With
overcast skies, surface heating will be limited keeping highs in
the upper 60s to near 70. Warmest temperatures will actually be
in the north near the canadian border where the showers won't
arrive until late afternoon. The colder temperatures will limit
instability and general showers are expected with just a slight
chance of thunder in the afternoon when some elevated
instability may be enough to get a bit of lightning.

The storm coverage will decrease overnight as the sunsets
however the moisture will remain trapped in the boundary layer
resulting in areas of fog. Low temperatures will remain in the
mid 50s.

Rainfall totals should generally be near 0.75-1" across the
region, with some totals of up to 2 inches possible in some of
the more intense showers. This should provide some needed relief
from the ongoing drought.

Long term Sunday through Friday
The deterministic model solutions are now in decent agreement on
the long wave pattern into next weekend. A weakening shortwave
impulse is sliding offshore as we begin the period. At the
surface... A weak surface low is exiting the gulf of maine along a
wavy frontal boundary oriented west-to-east across southern new
england. In its wake... A mostly cloudy Sunday with some early
morning fog and drizzle. Meanwhile... Shortwave energy along the
u.S. Canadian border has begun to carve out another upper trough
across the great lakes and northeast conus. This trough will slide
quickly eastward and help drive a cold front across the area with
a few showers and thunderstorms late Sunday and Sunday night.

Late Sunday could be interesting over far southwest new hampshire
with a few strong storms... If we breakout and see some heating as
dew points rise into the 60s and temperatures warm into the upper
70s and lower 80s. On Monday... Instability clouds and a few
showers... Especially across our northern and eastern zones as the
upper trough pivots across the forecast area. In the wake of this
upper trough... Rising heights under building high pressure
surface and aloft with warm dry weather for Tuesday and Wednesday.

Over the past day... The models have trended towards a faster
arrival time with the next shortwave impulse from the great lakes.

This impulse and associated surface low and frontal system will
arrive Wednesday night then linger for Thursday. Several
additional weak poorly timed impulses and surface troughs will
quickly follow for Friday and the start of next weekend.

Aviation 02z Saturday through Wednesday
Short term...VFR conditions will continue through the overnight
with increasing clouds. Clouds will begin to thicken and lower
as a warm front approaches on Saturday morning becoming MVFR.

Showers and MVFR will persist through the day on Saturday.

Overnight showers will end but areas of ifr fog are possible at
all terminals.

Long term...

sun - mon... Areas of MVFR in shra -tsra with local ifr in
drizzle and fog.

Marine
Short term... Quiet conditions on the waters. Increasing clouds
overnight as a warm front approaches the area. Overcast skies
through the weekend with showers and areas of fog developing by
late Saturday night into Sunday.

Long term... Mon... Scas are possible outside the bays.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

Near term... Hanes
short term... Curtis
long term... Schwibs

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.
