Synopsis
Warm, summer-like day ahead of a sweeping cold front this afternoon
into evening with isolated to scattered showers and thunderstorms,
some of which may be strong to severe. Dry, cool air building in
overnight. Seasonable weather with windy conditions Tuesday. Dry
weather continues Wednesday into Thursday with less wind, then
a period of showers will likely impact the region sometime late
Thursday into early Friday. Summer like warmth may return by the
end of next weekend.

Near term until 6 am Tuesday morning
4 pm update ...

* highlights ...

- isolated to scattered showers and thunderstorms
- strong to severe threat expected to be very isolated, if any
- biggest threat of strong to damaging winds with any strong to severe
- exiting this evening
* discussion ...

now (4 pm update) ...

isolated to scattered showers have developed, struggling to mature
further into thunderstorms with decent reflectivity above -10c given
marginal lapse rates aloft and pronounced dry air above h7. With any
updrafts, more than likely they are being choked off, keeping activity
low-topped. Despite the instability and effective shear, confident
that we'll not see widespread strong to severe, rather very isolated.

Perhaps lift along the sweeping cold front will push storms higher,
in an environment of sw-ne uni-directional shear yielding a potential
strong to severe wind threat along with heavy rain, frequent lightning.

But low confidence. Href and especially nssl WRF have the right trends
in mind with isolated to scattered activity, some of it multi-cellular
mini-clusters given the environment and anticipated pulsing storm-mode.

Will hold with severe thunderstorm watch 198 for the time-being, see
if something gets going. Likely a pulse will go up here and there,
then come down, and with the model forecast inverted-v soundings,
could see some localized wind damage.

Short term 6 am Tuesday morning through Tuesday night
Tuesday into Tuesday night ...

cool, dry airmass in place. Scattered cloud decks developing as
the boundary layer becomes well mixed with highs getting up to
around 70 degrees. Momentum mix down along with drier air,
looking at dewpoints in the 30s and NW wind gusts up around 20
to 25 mph. Should winds subside during the evening and overnight
periods, then perhaps radiational cooling could proceed,
especially over N W ma and ct sheltered valleys allowing
temperatures to drop into the upper 30s.

Long term Wednesday through Monday
Highlights...

* dry and pleasant Wed into Thu with less wind
* a period of showers possible late Thu into early fri
* summer like warmth may return next Sunday-Monday
details...

Wednesday...

pleasant day Wednesday as surface high pressure moves in with a
building ridge at the mid levels. Winds come down from Tuesday and
should be light with a relaxed pressure gradient. Plenty of Sun to
be had, and high temperatures expected to climb into the upper 60s.

Thursday and Friday...

Thursday will be mostly dry as the ridge axis crosses southern new
england, but our next shot of rain comes late in the day through the
overnight hours. A shortwave riding over the ridge moves through
Thursday night bringing increased moisture in the form of clouds
during the day Thursday, and increasing risk of showers Thursday
evening through at least early Friday. Ahead of the low, pwats top
1.5" with plenty of low level forcing given a 35-40kt LLJ at 925mb.

System moves off to the southeast and rain comes to an end later
Friday. Placement of the low over sne or just to the east will bring
easterly winds Friday and cooler than average temps in the low 60s
(50s along the coast).

Saturday through Monday...

behind Friday's departing system we see building high pressure and
the return of mid level ridging. This should lead to a dry and sunny
Saturday before a low over qc swings a cold front through Saturday
night into Sunday bringing another chance of rain. Uncertainty
increases for the far extended forecast, but trends are toward a
warmer and mostly dry forecast late Sunday into Monday under
building high pressure. Temps look to reach into the 70s each day.

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.
