.DISCUSSION...
KEY MESSAGE 1...Cooler with westerly breezes this weekend. Risk of
scattered afternoon showers thru sundown, then scattered showers and
a rumble of thunder on Sunday afternoon, but risk for severe
weather is very low.
Cyclonic mid-level flow governs our weather in Southern New England
this weekend. In that broader cyclonic flow aloft, a stronger closed
low over Quebec is expected to dig south-southeast into Maine and
the Gulf of Maine Saturday afternoon. Another weaker disturbance
moves through the flow on Sunday. Each of these disturbances will be
responsible for diurnally-driven scattered shower activity, with a
little more (if still weak) instability leading to scattered diurnal
showers with a risk for a thunderstorm or two. Highs should be in
the 70s to lower 80s on Saturday, and in the low 80s on Sunday, but
both days feature comfortable humidities.
Westerly winds have been gusting to 25-35 mph this afternoon with
the cold pool of air aloft helping to drive good mixing. Most models
show the low-level jet increasing post-sundown, but by that point,
more limited mixing as temperatures fall should temper the gusts to
around 20-25 mph. Gust speeds are expected to be similar by mid-
morning Saturday too - around 25 to 30 mph - but the directions are
more from the NW than today.
Shallow, weak instability is forecast for Saturday, and with a
little better dynamics coming down from the upper trough on
Saturday, best chance for afternoon scattered showers is from
Springfield to Providence north and east. Not everyone sees
these showers, but there will be some to dodge during the
afternoon to early evening hours. With temps running a few
degrees warmer on Sunday, there`s a better risk for pop-up
showers with a garden-variety thunderstorm or two possible
during the daytime hours.
KEY MESSAGE 2...Periods of heavy rain possible Monday into
early Tuesday. Drier air with seasonable temperatures expected
midweek.
A 500mb closed off low will slowly rotate through the upper Great
Lakes region with a weak shortwave trough moving into the Northeast
on Monday. At the surface, a low pressure system will track across
Southern New England, bringing significant moisture to the region.
Models continue to show precipitable water values of 1.50 to 2.00
inches, which would be well above climatological normals for mid
June. Widespread precipitation is likely mainly Monday into Monday
night with pockets of heavy rainfall possible. The latest National
Blend of Models run continues to show high probabilities (around 80%
chance) of greater than 1 inch of rainfall areawide and around 50%
chance of greater than 2 inches.
Behind the system, high pressure and northwest flow will bring
rapidly drying conditions during the day on Tuesday. Temperatures
are then expected to be pleasant midweek with seasonable highs in
the upper 70s to low 80s and only isolated rain chances possible
at the end of the period on Thursday.

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
00z TAF Update:
Through Tonight: High confidence.
VFR. A spot shower possible toward BDL around 23-01z but
confidence has increased enough to mention in the TAF. W wind
gusts 25-30 kt, and though they should begin to ease some after
sundown, still could see gusts in the 20-25 kt range overnight
as the low-level jet increases, especially over the Cape and
Islands.
Saturday: High confidence.
VFR; some risk for diurnal SHRA with brief MVFR-VFR visbys
after 17z mainly from BDL to PVD north and east through sundown
and indicated with PROB30s. Confidence is highest in showers for
the eastern most terminals with lower confidence across the
western terminals. WNW winds again gusting 25-28 kt by mid-
morning Saturday, then easing into sundown.
Saturday Night: High confidence.
VFR, any showers diminish post-sundown. WNW winds decrease to
5-10 kt.
KBOS Terminal...High confidence in shower activity and moderate
confidence in the exact timing. Westerly gusts 25-30 kt
continue through sundown, but will still be clocking in around
20-25 kt overnight tonight.
KBDL Terminal...Moderate confidence in TAF. A brief round of
showers may impact the terminal this evening, although activity
is rapidly diminishing. On Saturday, some diurnal showers are
possible throughout Southern New England, but there is lower
confidence on how far west they may reach, so have opted to
exclude from the TAF.
Outlook /Saturday Night through Wednesday/...
Sunday: VFR. Breezy. Chance SHRA, slight chance TSRA.
Sunday Night: VFR.
Monday: Mainly VFR, with local IFR possible. Breezy. SHRA,
chance TSRA.
