Area forecast discussion, Jul 12, 3:08 AM EDT, 24 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
308 AM EDT Thu Jul 12 2018
.SYNOPSIS...
High pressure brings dry weather with seasonable temperatures
and comfortable humidity through Friday. A return to hot weather
is expected later this weekend into early next week. While a few
thunderstorms cannot be ruled out this weekend into early next
week, dry weather looks to dominate the majority of the time.
&&
.NEAR TERM /THROUGH TODAY/...
Mid level trough axis will be over New Eng today and soundings
show steep low level lapse rates this afternoon. Enough moisture
in the 850-700 mb layer for sct-bkn cu developing. While a
brief shower in the interior can't be ruled out per some of the
hi-res models, expecting a mainly dry day as environment is
stable and overall moisture in the column is limited.
Temps aloft similar to Wed, so expect highs in the low/mid 80s
interior and 70s along the coast where sea breezes are likely.
Comfortable humidity levels with dewpoints in the 50s.
&&
.SHORT TERM /TONIGHT THROUGH 6 PM FRIDAY/...
Tonight...
Quiet night with mostly clear skies and light winds leading to
another cool night with lows mostly in the 50s, with lower 60s
urban centers. Patchy late night radiation fog is possible in
the typical prone locations.
Friday...
Mid level trough sharpens east of New Eng as shortwaves rotate
through the flow. Not much change in sensible weather with sct-
bkn cu developing but mainly dry weather as mid level temps are
warming with stable environment. Not much change in 925 and 850
mb temps so expect another day with highs low/mid 80s interior
and 70s along the coast with sea breezes.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Overview...
11/12Z model guidance remains in good overall agreement on the
evolution of the synoptic pattern through next Tuesday. Potent
high pressure over the central and western CONUS will lead to
slight height falls over New England. A cold front will move
into the Great Lakes on Friday, but should dissipate with time.
Still thinking a potent mid level trough will approach southern
New England toward the middle of next week. Will continue to
favor a consensus approach to smooth over the less predictable
details.
Temperatures...
Near normal temperatures expected this weekend, before the heat
and humidity start to increase early next week. Another round
of 90+ degree heat is possible for portions of the region.
Humidity anticipated to drop off behind a cold front sometime
during the middle of next week.
Precipitation...
Mainly dry weather for most of the time through Monday. Still
cannot rule out some pop-up showers/thunderstorms during this
time. More widespread risk for showers, and perhaps a few
thunderstorms, ahead of a cold front toward Tuesday and
Wednesday of next week.
&&
.AVIATION /07Z THURSDAY THROUGH MONDAY/...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Short Term /through Friday/...High confidence.
VFR with sct-bkn diurnal cu developing each afternoon. Sea
breezes likely today and Fri. Some patchy late night fog
possible in the typical prone locations.
KBOS Terminal...High confidence in TAF. Sea breeze developing
15-17z. .
KBDL Terminal...High confidence in TAF.
Outlook /Friday Night through Monday/...
Friday through Friday Night: VFR.
Saturday through Saturday Night: VFR. Slight chance SHRA.
Sunday through Monday: VFR.
&&
.MARINE...
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Short Term /through Friday/...High confidence.
Swell from hurricane Chris is diminishing. Some 5 ft seas may
linger into the morning over southern outer waters, otherwise
seas below 5 ft through Fri. Generally light winds turning
onshore over nearshore waters during the afternoons as sea
breezes develop.
Outlook /Friday Night through Monday/...
Friday Night through Saturday: Winds less than 25 kt.
Saturday Night through Sunday: Winds less than 25 kt. Seas
locally approaching 5 ft.
Sunday Night through Monday: Winds less than 25 kt.
&&
.TIDES/COASTAL FLOODING...
Astronomical tides will be rather high during the night time
high tide cycles tonight through Sat night. Fortunately wave
action will not be much of a factor and surge is limited.
However, leftover SE swell may result in minor splashover for
vulnerable areas along east coastal MA tonight.
Tides are a slightly higher Fri night and Sat night so
additional rounds of splashover are possible during these high
tide cycles.
