Synopsis
High pressure in control today with seasonably warm conditions.

A fast moving disturbance will bring a period of showers and
perhaps a few embedded thunderstorms tonight. Mild and dry
conditions expected during the latter portion of the holiday
weekend. High pressure pushes off the coast early Tuesday. Low
pressure then lifts northwest of new england, allowing frontal
systems to move across the region late Tuesday through Wednesday
bringing showers and scattered thunderstorms. Unsettled
conditions linger into Thursday with warm temperatures. A cold
front pushes offshore late next week, with drying conditions and
mild temperatures.

Near term until 6 pm this evening
715 am update...

noting low clouds and patchy, locally dense fog across the
normally susceptible locations in the ct valley into NE ct and
portions of interior E mass since around 08z or so. A few
spots, where winds were calm, have visibility down below 1 2sm.

With mainly clear skies above these low clouds, should burn off
by mid morning.

Can see this patchy fog in the river valleys on the latest
goes-east visible satellite imagery, and can see the fog
burning when looping the imagery since sunrise. Also able to
see bands of thin cirrus pushing SE out of ny central pa early
this morning.

Near term forecast on track, but have updated to bring
conditions current.

Previous discussion...

high pres in control today as it shifts south of new eng with sw
flow developing. Expect lots of sunshine today, although some
increase in mid high clouds during the afternoon ahead of next
shortwave. Highs should reach well into the mid 70s with light
winds for most locations, but developing sea breezes will hold
temps in the upper 60s along the immediate coast.

Short term 6 pm this evening through 6 pm Sunday
Tonight...

a fast moving shortwave from the gt lakes will pass to the
north late tonight. Models all indicate a developing low level
jet tonight which will bring a decent instability burst as low
level theta-e ridge and increasing ki moves into the region.

Expect a period of showers developing from west to east late
evening into the overnight. A few t-storms are possible as well
as soundings indicate a conditionally unstable profile above the
inversion with marginal mucapes. Gusty SW winds will develop as
the low level jet moves into the region. Gusts 20-30 mph are
possible.

Sunday...

shower activity will be exiting SE new eng in the morning, with
areas of low clouds giving way to increasing sunshine as good
low and mid level drying develops. Clouds may linger over the
cape islands through midday. It will be a warm day with
westerly winds and 850 mb temps 20-21c supporting highs into
the mid 80s with some upper 80s possible ct and merrimack
valleys. Cooler 70s along the immediate south coast where winds
turn sw. Weak cold front moves into sne in the afternoon and
models generating sbcapes 500-1000 j kg. Limiting factor for
convection is the very dry air which moves in above 700 mb which
will limit any potential updrafts. Mainly dry weather in the
afternoon with just a low risk for a brief shower or perhaps a
low topped t-storm but coverage would be localized. Steep low
level lapse rates develop in the afternoon with deep mixed layer
supporting gusty west winds to 20-30 mph at times, especially
interior locations.

Long term Sunday night through Friday
Highlights...

* dry and mild conditions Sunday night and memorial day
* turning cooler Tuesday as low pressure shifts across,
bringing showers and scattered thunderstorms
* a front lingers across the region Wed and Thu with unsettled
conditions and mild temperatures
* could see dry and seasonable conditions toward the end of the
work week
overview...

fast moving northern stream systems continue as a low amplitude
mid level steering flow remains in place, keeping weather
systems moving across the region. Broad subtropical ridge
lingers across the central and southern tier, so the storm track
will allow weather systems to push across the region. Noting
widening model solution spread thanks to timing and track issues
of individual systems lending to lowering confidence through
next week.

Should see showery periods as each system passes. Instability
increases from Tuesday night through Thursday as one system
moves out, followed quickly by a second, potentially more
potent systems. At this point, looks like best shot for showers
and thunderstorms that may occur around mid to late next week.

May see the mildest temps of the week around Thursday, which
could help kick up the convection a bit higher. May see dry and
seasonal conditions late next week, but will depend upon the
exit of the low pres cold front Thu night as well as ridge
building east.

Details...

Sunday night and memorial day...

the cold front should push offshore Sunday evening, allowing
winds to shift to w-nw that will bring drier conditions. Expect
overnight lows to range from the lower 50s across the higher
terrain to around 60 across the coastal plain with light w-nw
winds in place.

High pressure builds across the northeast on memorial day with
mostly sunny skies for most areas. Expect temps to run close to
or a bit above normal, topping off in the mid-upper 70s inland,
but will be cooler along the coast and especially across outer
cape cod with light e-ne winds in place.

Monday night through Thursday...

another warm front approaches as low pressure pushes across the
eastern great lakes and along the us canadian border, will see
another round of showers move in late Monday night into Tuesday.

Models trying to briefly dry things out, but increasingly wide
timing of systems lends to lower confidence. With the fast flow
aloft, could see precip from the next system approach as well.

Have kept chc to lkly pops going for this particular system.

Increasing instability ahead of warm front Tue night may also
mean some convection kicking off, with slis from zero to -2, k
indices in the lower 30s and tq values in the upper teens. Have
mentioned thunder in the forecast for Tue night and wed.

Expect milder temperatures Wed and especially Thu as the warm
front lingers across the interior or possibly further n, with
the low amplitude pattern in place, steering track will keep w-e
moving systems moving along.

Should see next system approach Wed night into thu, bringing
another batch of showers and scattered thunderstorms.

Forecasting the mildest temps of the week late Wed or Thu as h85
temps rise to +16c to +18c crossing southern areas around
midday or during the afternoon on thu. This will also keep
increased instability moving across as well.

May see highs on Thu top off in the upper 70s to lower 80 at
most locations, but may be cooler across the higher terrain and
along the immediate S coast, CAPE cod and the islands on s-sw
winds.

Thursday night and Friday...

timing of the approaching cold front in question due to timing
and track issues Thu night, but should pass across overnight thu
night into early Fri morning as cooler air moves in behind the
front. Might some some lingering showers during the day on
Friday across eastern areas as temps rise to the mid and upper
70s, except 65 to 70 across outer CAPE cod and the islands, and
near 70 across the higher terrain.

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.
