.SYNOPSIS...
A cooler air mass will settle over the region today and
Thursday. In a departure from recent weather, high temperatures
will remain in the low to mid 60s. Overnight will feel even more
fall- like, with widespread low temperatures in the 30s and
even 20s in the northern valleys. Frost will be possible even
into coastal areas. By Friday warmer weather will begin to
return, with above normal temperatures right through the middle
of next week. The one consistent feature of the next week or so
will be continued dry weather.
&&
.NEAR TERM /THROUGH TODAY/...
High pressure steadily builds in from the north through the day
today. The high brings with it a dry airmass with seasonable
temperatures and mainly sunny conditions. Highs range from the
mid 50s across the north, to the mid 60s along the coast. A
north breeze will be noticeable today as well, with gusts of
around 20-25 mph through the day.
A south-southeasterly swell generated by Hurricane Humberto
continues to build today. A high surf advisory has been issued
for the building waves and high risk for rip currents. A 5-7ft
swell with 14-15 second period persist through the day.
&&
.SHORT TERM /TONIGHT THROUGH 6 PM THURSDAY/...
The high continues to build in overnight, with excellent
radiational cooling conditions setting up for tonight. With the
dry airmass, widespread lows in the upper 20s are likely across
the north, with low 30s across much of the interior. Mid to
upper 30s will be reserved for the coastline, with some low 40s
likely through the Seacoast of New Hampshire. Frost/freeze
headlines will likely be needed across most of the interior
tonight, but we`ll allow this morning`s headlines to play out
first before issuing the next time period`s.
Another bright and seasonable day is in store for tomorrow,
with highs ranging from the upper 50s across the north, to the
mid 60s along the coast. Winds gradually turn onshore during the
afternoon hours tomorrow as the high pressure center slides
offshore. Winds will be lighter tomorrow and ease through the
daytime.
Waves gradually lower through the day tomorrow, but another day
of at least strong rip currents is expected. A rip current
statement or high surf advisory will likely be needed along the
coast tomorrow, but we will continue to handle these headlines
one day at a time.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
Key Message: High pressure stays in control of the weather thru
the coming weekend. Dry conditions will persist along with
temps turning above normal again.
Impacts: Drought conditions will continue and may expand as
another long stretch of dry weather is anticipated. Frost will
be possible again Thu night. Warming conditions into the weekend
may also lead to increasing fire weather concerns.
Forecast Details: High pressure will be centering over the
Northeast at the start of the period...drifting slowly southeast
thru the weekend.
Extremes in the ensemble guidance is dominated by the tropical
systems well out to sea in the western Atlantic. Locally the
only major signal for anomalous weather will be warm conditions
arriving this weekend and continuing into early next week. The
signal makes sense as surface ridge axis slips south of the
forecast area and southwest winds return the warmth back north.
This may manifest with temps climbing into the 80s. It is
possible high temps will be within a few degrees of daily
records.
More importantly thought will be another extended stretch of
dry weather. Some guidance hints at a subtle cold frontal or
backdoor cold frontal passage for at least parts of the area
this weekend...but in all likelihood it will be a dry passage.
So despite the rain we just had...another week or so without
rainfall will just erase those gains. Drought will continue and
may even expand further.
Otherwise Thu night will be another good opportunity for cold
temps and frost for many areas. And as high pressure remains
centered nearby radiation fog will also be possible most nights.
However drought and leaf drop will start to bring an end to the
widespread threat of fog over the coming week...especially in
northern valleys.
&&
.AVIATION /05Z WEDNESDAY THROUGH SUNDAY/...
Short Term...VFR prevails through tomorrow at most terminals.
Valley fog is possible at LEB early this morning, but is not as
likely as the last few nights. Restriction in valley fog is more
likely at LEB tonight.
Long Term...High pressure dominates our weather thru the coming
weekend. Largely VFR conditions are expected...especially
during the day. Overnight radiation fog will be
possible...though drought and growing leaf drop will tend to
limit coverage. Still local IFR or lower conditions are possible
at LEB and HIE.
&&
.MARINE...
Short Term...High pressure continues to build in from the north
through tonight, with the center then crossing the waters
tomorrow. A north wind with gusts of around 25-30kt is likely
today. A southerly swell from Hurricane Humberto continues to
build into tonight, and gradually lowers tomorrow. SCA
conditions likely continue through at least tomorrow afternoon
with the swell.
Long Term...Seas will continue to diminish thru Thu night. High
pressure will remain in control thru the weekend with winds and
seas expected to remain below SCA thresholds.
