Area Forecast Discussion
National Weather Service Boston/Norton MA
327 PM EDT Tue Jul 10 2018

.SYNOPSIS...
Another hot afternoon is on tap today and an approaching cold
front will trigger scattered showers and thunderstorms late
today and tonight. A few strong storms are possible in the
interior. Tropical Storm Chris is expected to intensify into a
Hurricane today but pass well southeast of Nantucket Wednesday.
High pressure will build over the region Thursday and Friday
resulting in mainly dry weather along with seasonable
temperatures and comfortable humidity levels. A return to hot
weather is expected later this weekend into early next week. While a
few thunderstorms can not be ruled out this weekend into early next
week, dry weather looks to dominate the majority of the time.

&&

.NEAR TERM /THROUGH 6AM WEDNESDAY/...

Temperatures at 850mb are near 19C and are mixing down to the
surface where sites are seeing temps near or surpassing 90F. The
approaching cold front is currently just SE of the Canadian/New
York border where a line of CU and a few isolated thunderstorms
are popping up.

Looking at several Hi-Res models, the potential for any strong
to severe thunderstorms looks to be diminishing across SNE. Dry
air aloft doesn't seem to move out of the region until 00z and
given that current dewpoints across the region are in the low
60s and mid 50s, showers and thunderstorms will have a difficult
time forming with the lack of moisture. In addition, westerly
winds will provide minimal to no surface convergence. The best
chance for any thunderstorms developing will be on the eastern
slopes of the Berkshires and the Worcester Hills due to
upsloping winds. Higher terrain is also colocated with the
strongest shear and instability. The main time frame for storms
looks to be between 21z and 02z.

Isolated showers and thunderstorms may continue into the
evening, when the best synoptic forcing, shear, cooling temps
aloft, and instability arrive in SNE. Some heavier showers are
possible late tonight where PWATs overnight reach up 1.75" and K
indicies are up to 38.

Temps are expected to remain in the 60s overnight, but if
clouds associated with the cold front clear out before sunrise,
some radiational cooling is possible, especially in western MA
across the higher terrain.

ACK may see a brief period of fog just before sunrise tomorrow
as SW winds diminish after the frontal passage and an inversion
remains overhead.

&&

.SHORT TERM /6AM WEDNESDAY THROUGH WEDNESDAY NIGHT/...

Wednesday...

Cold front will be sitting just east of Nantucket come sunrise
tomorrow morning with some possible lingering showers and
thunderstorms across RI and SE Mass.

As the front moves offshore and instability erodes throughout
the morning, any lingering showers and thunderstorms will
dissipate across SE New England.

There's a small chance for isolated showers tomorrow afternoon
across northern CT and central MA given cyclonic flow and
cooling temps aloft, but these will likely be short lived with
very little impact.

Tropical storm Chris is expected to pass 300 miles to our SE,
resulting in high surf and dangerous rip currents along south
coastal beaches. High surf advisories may be needed.

Wednesday will be much cooler than today as winds out of the NE
keep the region in the mid 70s. The warmest temperatures are
likely to be in the Connecticut River Valley where Hartford may
see 80 degrees. Behind the cold front, humidity will decrease as
dewpoints will be in the mid to upper 50s across the region.

Wednesday night...
Strong NE winds and high surf will continue into the evening
as TS Chris departs the region and continues moving NE. Skies
will be mostly clear as a 1024mb High builds into New England,
allowing temperatures to cool into the 50s overnight.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
Highlights...

* Mainly dry Thu/Fri with seasonable temps and comfortable humidity

* Hot weather returns late this weekend into early next week and
  while a few t-storms are possible dry weather should dominate

Details...

Thursday and Friday...

Distant tropical system Chris well east of the Benchmark Wed evening
will rapidly move northeast and be located east of the Canadian
Maritimes by Thu.  This should allow lingering southeast swell/rip
current risk Thu to diminish by Fri. Otherwise...high pressure to
our north will result in mainly dry weather although a spot shower
can not be ruled out Thu with a moisture starved shortwave.
Seasonable temperatures with comfortable humidity levels on tap for
the region on both Thu and Fri.

This Weekend Into Early Next Week...

Upper trough will exit the region this weekend allowing for rising
height fields into early next week.  The result will be the return
to hot afternoons at least away from any marine influences on the
immediate coast.  Certainly the potential for a couple days of 90+
degree heat.  Synoptic scale forcing does not look favorable for
much precipitation...but can not rule out a few t-storms.  Timing of
that risk is highly uncertain and regardless the vast majority of
this period will likely feature dry weather.

&&

remains aloft.

Wednesday...

in early morning.

Mainly VFR. Strong winds out of the NE across SE New Eng.

KBOS Terminal...High confidence in TAF. Greatest risk for a few

build up to 8 ft possible over the southern waters. A High Surf
