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
Rain showers will focus themselves to the south of the massachusetts
turnpike this evening before moving offshore... But a few left
over showers will remain possible overnight ahead of a cold
front. Mainly dry weather with warm afternoons are anticipated
Wednesday, Thursday and Friday. Another cold front will drop
south and bring a chance for a period of unsettled weather
during the holiday weekend... But not expecting a washout.

Near term through tonight
310 pm update...

an approaching surface warm front modest low level jet will
continue to generate some light rain showers into this evening.

The bulk of these showers will begin to focus themselves south
of the pike and especially near the south coast... Where stronger
forcing resides. While most of the showers will be light... Some
briefly heavier showers may occur near the south coast with
even the low risk for a rumble of thunder.

Late this evening and into the overnight hours will feature
mainly dry weather as deeper forcing will have exited the
region. However... Still expect a few showers overnight as a weak
cold front crosses the region.

The other concern will be for areas of fog developing overnight given
light southerly flow and increasing low level moisture. Main
focus for the more widespread fog will be along the south coast,
cape and islands. Overnight low temps should only drop into the
lower to middle 50s.

Short term Wednesday through Wednesday night
Wednesday...

a beautiful day is in store for the region as drier air works in
behind the weak cold front. Partly to mostly sunny skies should
allow high temperatures to reach the lower 80s in many
locations away from localized coastal sea breezes. While dry
weather will dominate... A shortwave and a local sea breeze
boundary may be enough to trigger a few brief late
afternoon early evening spot showers across eastern ma.

Wednesday night...

if a few brief spot showers are able to develop across eastern
ma... They should dissipate after sunset. Otherwise, dry and
tranquil weather anticipated as a weak ridge of high pressure
noses in from the west. Overnight lows should bottom out in the
upper 40s to middle 50s.

Long term Thursday through Monday
Big picture...

the flow over north america will continue to feature northern and
southern streams. Trough in the southern stream will continue to
linger over the gulf of mexico through the week. Meanwhile the
northern stream will feature one shortwave moving east of new
england Wednesday night and a second shortwave ejecting from the
western usa, then phasing with another shortwave from northern
canada over the weekend as it moves east toward new england.

The solutions show agreement through Friday, then diverge in details
over the weekend and early next week. So confidence is good through
Friday, then diminishes over the weekend.

Contour heights remain above normal through the period. Expect much
of this time to feature near or above normal temperatures.

Concerns...

Thursday through Saturday...

high pressure center moves overhead Thursday. It then settles to our
south Friday and Saturday, bringing a westerly flow to our region.

The weak flow Thursday will allow sea breezes. Mixing will reach 850
mb with temps aloft supporting MAX sfc temps in the low to mid 70s
but cooler along the coast. The westerly flow Friday and Saturday
will be an offshore flow most places and bring warm temperatures all
the way to the coast. Mixing should reach to 800 mb Friday and
Saturday, with temps at that height supporting MAX sfc temps in
the 80s. A cold front drops south from canada on Saturday, with
a chance of showers in the afternoon and at night as it moves
through southern new england. Best chance of showers will be in
northern mass.

Sunday-Monday...

cold front moves south of the region Sunday, but stalls close enough
to support showers during this time. Meanwhile, high pressure tries
to nudge south over the maritimes and bring drier weather to new
england. Confusing? Consider the GFS which also feeds gulf moisture
up the coast while the ECMWF keeps it well to our south. Low
confidence in the forecast for these two days. We will show a low-
end chance of showers both days.

Aviation 19z Tuesday through Sunday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Wednesday night ...

tonight... Moderate to high confidence. Ceilings and visibilities
should gradually lower this evening and especially after
midnight. Timing uncertain but widespread MVFR conditions
should develop with locally ifr lifr focused across the south
coast, CAPE and islands where the greater risk is for lower
clouds and fog. Some showers mainly this evening focusing south
of the pike with even the low risk for a rumble of thunder near
the south coast.

Wednesday... High confidence. Lingering lower CIGS vsbys should
improve toVFR by late morning early afternoon in all locations.

These conditions will be slowest to improve across the CAPE and
islands. Low risk for an isolated late afternoon early evening
shower or two across eastern ma.

Wednesday night... High confidence inVFR conditions.

Kbos terminal... High confidence in taf. Sea breeze should come
to an end early this evening.

Kbdl terminal... High confidence in taf.

Outlook Thursday through Saturday ... Moderate confidence.

Wednesday night through Thursday night:VFR.

Friday through Friday night:VFR. Breezy.

Saturday: mainlyVFR. Local MVFR possible in fog and afternoon
showers. Breezy.

Marine
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Wednesday night ...

tonight through Wednesday night... High confidence. Weak pressure
gradient will keep winds and seas below small craft advisory
thresholds through Wednesday night. Showers this evening with a
low risk of an embedded t-storm across the southern waters. Main
concern will be areas of fog overnight into part of Wednesday
morning... Which may be locally dense especially across our
southern waters.

Outlook Thursday through Saturday ... Moderate confidence.

Wednesday night: winds less than 25 kt. Seas locally
approaching 5 ft.

Thursday through Thursday night: winds less than 25 kt.

Friday: low risk for small craft advisory with seas approaching
5 feet. Wind gusts near 20 kt.

Friday night: winds less than 25 kt. Local rough seas.

Saturday: winds less than 25 kt. Areas of seas approaching
5 ft. Slight chance of afternoon rain showers.

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.
