What forecasters said that day

The local office's own words before this freeze warning 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 freeze warning went out at Oct 17, 1:53 PM EDT, 1 hour 25 minutes earlier.

Area forecast discussion, Oct 17, 1:53 PM EDT, 1 hour 25 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
153 PM EDT Wed Oct 17 2018

.SYNOPSIS...
A cold front moves across the region this afternoon with some
brief scattered showers and gusty winds...followed by the coldest
air of this young fall season tonight and Thursday along with windy
conditions. Cooler than average temperatures persist through the end
of the week into the weekend. A shot of some showery weather ahead
of a sweeping cold front Saturday. Breezy conditions at times.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
150 PM update

Scattered showers assocd with a cold front will be moving into
SNE through the afternoon with main focus north of the Pike.
Otherwise, increasing strato-cu across the region. Good mixing
and pressure rises behind the front will likely result in a
brief surge of 25-35 mph west winds and possibly near 40 in
showers, especially over higher terrain. Temps near highs for
the day, 60-65 coastal plain and mid 50s higher terrain.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
* Unseasonably cold tonight and Thursday
* Wind Headlines possible later tonight into Thu AM

Tonight...

An unseasonably cold airmass will be ushered into the region on
gusty northwest winds tonight. A few left over sprinkles or
perhaps even a few high terrain snow flurries will be possible
this evening. Otherwise...850T dropping to between -8C and -10C
will result in a cold night. Low temperatures by daybreak will
range from the upper 20s across the high terrain...to the lower
to middle 30s elsewhere. While the wind will stay up to prevent
the need for any frost headlines...we have issued a Freeze
Watch for areas expected to drop near or just below freezing
where the growing season has not officially ended. Opted to go
with the watch as opposed to a warning given temperatures will
be marginal and wanted to let the next shift get a look.

As for winds...expect northwest wind gusts of 25 to 40 mph at times.
Some guidance shows these winds diminishing a bit this evening
behind the cold front...but picking back up after midnight. We did
issue a wind advisory for the Cape/Nantucket...where confidence was
highest in criteria being met with NW winds blowing over the
relatively mild waters. Will need to watch the Worcester Hills too
and even the lower elevations as 850 mb winds increase to between
40 and 50 knots. These strong winds can sometimes mix down in these
setups...so an expansion to the headlines might be needed. Concern
is greater this time of year given fully leafed trees. Regardless...
the gusty winds will make it feel quite cold with wind chills in
the upper teens to middle 20s by daybreak Thursday.

Thursday...

A blustery and unseasonably chilly day is on tap for the region.
Despite plenty of sunshine...an anomalously chilly airmass will
hold highs in the lower 40s across the higher terrain with upper
40s elsewhere. It will remain rather windy with northwest wind gusts
of 25 to 40 mph and perhaps up to 45 mph in some locations during
the morning.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
*/ Highlights...

 - Touch of winter at times into the weekend, sub-freezing lows
 - Breezy conditions possible throughout warranting wind headlines
 - Average temperatures throughout below seasonable

*/ Overview...

Shots of colder air ahead. NE Atlantic anti-cyclonic wave break that
evolves into an omega block. Progressive N hemispheric pattern other-
wise. Through a preferred reloading NE N America H5 trof, individual
impulses develop into deep storms as they obtain greater curvature /
angular momentum across Greenland into Iceland. +AO, the Arctic door
is open. Behind aforementioned deepening lows, expecting equatorward
cold air shots ushered by anomalously strong isallobaric / pressure-
gradient forced low-level surface-H925 cold air advection, dropping
S roughly -1 to -2 standard deviation H85 temperature airmasses. Do
agree with the prior forecaster, the -EPO / +PNA trend only aids in
the downstream H5 trof preference through which cross-polar flow and
+AO gives us our first touch of Winter.

*/ Discussion...

So watching closely for frost / freezing conditions, as well as any
conditions that would warrant wind-headlines. Thursday night and
Sunday night especially with respect to cold-weather related head-
lines, watching for wind threats and impacts Saturday into Sunday.
Any outcomes associated with sweeping frontal boundaries, Saturday
especially, along which airmasses are more continental-polar, void
of deeper moisture. Cold, showery outcomes, mainly Saturday, that
are scattered to broken, hardly a washout. Otherwise the remainder
of the forecast is mostly dry with some warm rebounds in-between.
Preference to MOS guidance for 2m temperatures.

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Forecaster Confidence Levels...

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

Short Term /through Thursday/...High confidence.

Through 00z...

Friday: VFR. Breezy.

Friday Night: VFR. Windy with gusts to 30 kt. Slight chance
SHRA.

Saturday: Mainly VFR, with local MVFR possible. Windy with

.MARINE...
Forecaster Confidence Levels...

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

Short Term /through Thursday/...High confidence.

A cold front cross the waters late today. The result will be
west winds increasing to between 30 and 40 knots this afternoon.
Gale force NW wind gusts tonight into Thursday afternoon as
strong cold air advection over the relatively mild ocean will
support excellent mixing. Gale headlines remain posted for all
waters...except strong small craft headlines for Narragansett
Bay. Later shifts may have to consider upgrading this zone too
given the amount of mixing that will be generated over the very
mild waters.

Outlook /Thursday Night through Sunday/...Moderate to High

Thursday: Moderate risk for gale force winds with gusts up to
40 kt. Rough seas up to 13 ft.

Thursday Night: Low risk for Small Craft Advisory winds with
gusts up to 30 kt. Local rough seas.

Friday: Low risk for Small Craft Advisory winds with gusts up
to 25 kt. Areas of seas approaching 5 ft.

Friday Night: Moderate risk for Small Craft Advisory winds with
gusts up to 30 kt. Local rough seas. Slight chance of rain
showers.

Saturday: Low risk for gale force winds with gusts up to 35 kt.
Areas of rough seas. Chance of rain showers.

Saturday Night: Low risk for Small Craft Advisory winds with
gusts up to 25 kt. Local rough seas. Slight chance of rain
showers.

...A BRIEF PERIOD OF 35 TO 45 MPH WIND GUSTS MAY RESULT IN A FEW
DOWNED TREES AND ISOLATED POWER OUTAGES BETWEEN 2 AND 8 PM THIS
EVENING...

A strong cold front will cross the region this afternoon and
early this evening. A band of scattered showers may accompany
this cold front and result in a brief period of 35 to 45 mph wind
gusts, especially over the higher terrain. Given that we still
have fully leafed trees, the potential exists for a few downed
trees and isolated power outages. The main time of concern is
between 2 and 8 pm this evening.
