What forecasters said that day

The local office's own words before this frost advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Boston/Norton, MA wrote its last area forecast discussion before this frost advisory went out at Oct 8, 3:08 AM EDT, 13 minutes earlier.

Area forecast discussion, Oct 8, 3:08 AM EDT, 13 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
308 AM EDT Thu Oct 8 2020

.SYNOPSIS...
High pressure will provide dry weather for the next several days
as it builds across the region today and heads off the mid
Atlantic coast Friday. Temperatures will be cooler today and
Friday, then will warmup up this weekend, before turning cooler
again next week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Skies have cleared across most of SNE early this morning except
for some lingering low clouds near Berkshires. High pressure
building into region will continue to bring gusty W/NW winds
today, generally in 20-30 mph range with strongest gusts in
hills and along coast. Flow aloft remains cyclonic so expect
some diurnal clouds this afternoon, but overall airmass is dry
through column.

Highs will top out in 50s to lower 60s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
Winds will diminish this evening as high pressure builds
overhead. This will set up good radiational cooling conditions
away from coast and outside urban centers which will allow
temperatures to fall into mid 30s overnight in usual cold
spots. As a result we will issue a Frost Advisory for much of
central and interior eastern MA as well as northern/western RI
and NE CT.

High pressure becomes centered off mid Atlantic coast Fri,
setting up milder SW flow during afternoon. Similar 850 mb temps
as today so highs should only run a few degrees warmer than
today, from upper 50s to mid 60s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Big Picture...

Zonal flow across the northern USA Friday and Saturday, with an
embedded shortwave moving through the flow and crossing New
England/Eastern Canada Saturday/Saturday night. Another shortwave
moves ashore from the Pacific Ocean Saturday and digs a deep trough
over the Central USA by Monday. Hurricane Delta is expected to make
landfall in LA late Friday and move up the Mississippi Valley during
the weekend. The digging of that Central trough will encourage the
Delta remnants to move through the Midwest and Northeast USA
early next week.

Mass fields are quite similar through Sunday, bringing moderate-high
confidence to the Friday to Sunday forecasts. Model differences grow
Sunday night and Monday in the Plains due to different handling
of the deep trough. The track has also changed over the last 24
hours, so that consistency is low. Confidence in the arrival
and timing of the remnant into Srn New England is low at this
time.

Details...

Friday-Saturday...

High pressure builds over the region Friday and shifts offshore
Saturday. Expect dry air and subsidence both days. A warm front
moves through Friday evening and may bring a period of mid and high
clouds as it moves across.

Mixing reaches 900 mb Friday and 850 mb Saturday. This taps winds of
15 kt Friday and 30 kt Saturday. So gusty southwest winds are
expected Saturday. Temps at the top of the mixed layer are equiv to
1-3C Friday and 10-11C Saturday. The Saturday numbers are
colder than all but the bias-corrected guidance. The forecast
favors moving max temps Saturday up a couple of degrees. Min
temps of 45-55 are favored based on forecast dew points, but
there is room for inland temps to cool another 3-4F in
radiational cooling.

Saturday night-Sunday...

Cold front over Nrn New England moves southeast through Srn New
England, driven by a shortwave crossing eastern Canada. Moisture
cross-sections reach up to 700-mb, but dry air above that. Expect
some clouds with the front and possibly isolated showers. The front
moves south of the region early Sunday morning. High pressure then
builds across Nrn New England Sunday, turning our winds from the
north and then northeast. That means a marine flow and shallow
mixing, with 950-mb temps equiv to -1C to +3C, supporting upper 50s
to mid 60s.

Monday through Wednesday...

As noted, the GFS brings remnants from Delta to the Northeast USA
Monday afternoon through Tuesday. This is quite a change from 24-
hours ago when the model aimed for the Virginia coast and out to
sea. That adds uncertainty to whether this wetter track is correct
or a blip. The 12Z ECMWF behaves similar to the GFS. Both models
seem to be reacting to the digging of the deep trough over the
Plains. The forecast will support low-end chance pops Monday-
Tuesday, and slight chance pops Wednesday.

As noted above, confidence in this part of the forecast is low. With
more run-to-run consistency, would expect confidence to
increase.

&&

.AVIATION /07Z THURSDAY THROUGH MONDAY/...
Forecaster Confidence Levels...

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

06z TAFs: High confidence.

Local MVFR ceilings near Berkshires early this morning,
otherwise VFR. W/NW winds gusting as high as 25-35 kt today with
strongest gusts in hills and along coast. Diminishing NW winds
tonight, then winds turn SW by Fri afternoon.

KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Friday Night through Monday/...

Friday Night: VFR. Breezy.

Saturday: VFR. Windy with gusts up to 30 kt.

Saturday Night through Sunday Night: VFR. Breezy.

Columbus Day: Mainly MVFR, with areas VFR possible. Breezy.
Slight chance SHRA.

&&

.MARINE...
Winds have begun to subside on nearshore waters so we lowered
Gale Warnings to Small Craft Advisories for these areas, but are
keeping Gales posted farther offshore and off E MA coast for
marginal 35kt W/NW winds today. High pressure builds off mid
Atlantic coast tonight and Fri, resulting in lighter W/NW winds
tonight before winds back to SW by Fri afternoon.

Outlook /Friday Night through Monday/...

Friday Night: Low risk for Small Craft Advisory winds with
gusts up to 25 kt. Local rough seas.

Saturday: Low risk for gale force winds with gusts up to 30 kt.
Areas of rough seas.

Saturday Night: Moderate risk for Small Craft Advisory winds
with gusts up to 25 kt. Local rough seas.

Sunday through Sunday Night: Winds less than 25 kt. Seas up to
5 ft.

Columbus Day: Low risk for Small Craft Advisory winds with
gusts up to 20 kt. Areas of rough seas. Slight chance of rain
showers.

&&

.FIRE WEATHER...
Not much rain fell across region in past 24 hours, mainly less
than 0.25 inch. W/NW winds gusting to 25-35 mph today,
combined with low relative humidity ranging from 25 to 35
percent will result in elevated concerns for fire weather. We
will continue to highlight this through a Special Weather
Statement.
