Synopsis
High pressure will continue to bring an extended period of dry
weather right through the weekend. The high will initially be
accompanied by rather cool temperatures Tuesday night into Thursday
morning. A warmup occurs thereafter with unseasonably warm
afternoons expected by the weekend as highs may reach into the 80s.

Near term until 6 am Tuesday morning
No major changes to the forecast this evening. Brought the
forecast back in line with observed trends.

A ridge of high pressure in control will result in mainly clear
skies, light winds and a good night of radiational cooling
across the region. Low temperatures by daybreak should be down
into the 40s to the lower 50s in most locations.

Short term 6 am Tuesday morning through Tuesday night
Pleasant, fall-like day on tap for Tuesday. Under the influence of a
building surface high pressure, with dry northwest flow at the mid
levels downstream of an amplified ridge over the great lakes region
we will be dry will plenty of sun. The cooling temperature
trend also continues, dropping below normal for mid september as
low mid level flow becomes N then NE around the high. This
ushers in cold canadian air... 2-5c at 850mb by early Wednesday!
at the surface we can expect low temps in the mid to upper 40s.

One thing to watch given the anomolously cold NE flow over our
still relatively warm ocean waters will be the introduction of some
ocean affect clouds late tues and overnight, maybe even some
light rain drizzle. The column is very dry above 800mb but given
the substantial temp differential and low level moisture we may
squeeze out some light precip over northern and eastern ma
overnight; certainly nothing substantial or widespread

Long term Wednesday through Monday
Highlights...

* extended period of dry weather continues through the weekend
* cool Wed wed night with moderating temps Thu and especially fri
* unseasonably warm afternoon temps this weekend through mon
* high surf dangerous rip currents possible by Fri and sat
details...

amplifying trough over the canadian maritimes will allow for a shot
of cool air Wed into early Thu am. North to northeast low level
flow will probably generate a period of clouds and perhaps even a
brief sprinkle or two Wed am. The main story though will be the
cool temperatures with highs mainly in the 60s wed, perhaps
approaching 70 in the lower ct river valley. The coolest highs on
thu will be found on the eastern ma coast, where highs will struggle
to get past the lower 60s with the onshore flow.

Large high pressure in control will allow for rather cool temps wed
night into early Thu am. Lows should be well down into the 40s with
perhaps some middle to upper 30s in the normally coolest outlying
locations. This may lead to some patchy frost in a few of these
spots, but even if that occurs it should not be widespread.

Upper level ridging over the southern plains begins to push
northeastward Thu into Fri allowing for moderating temperatures
especially by fri. The ridge will then flatten a bit by the weekend
into mon. This will allow more of a west southwest flow aloft and
even warmer temperatures to overspread the region by the weekend
into next Monday. A good shot we see high temperatures reach into
the 80s for at least a couple of those days. These readings are
generally 10 to 15 degrees above normal.

The extended period of dry weather will continue through the weekend
with nothing more than perhaps a sprinkle or two Wed am with large
surface high pressure in control.

Meanwhile, hurricane humberto currently well east of the florida
coast will lift northeast, passing well east of our region by
late in the week. The only impact will be from swell resulting
in high surf dangerous rip currents by Fri and into the weekend.

This is a concern though for beachgoers especially given it
will be occurring with unseasonably warm temperatures.

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.
