What forecasters said that day
The local office's own words before this small craft 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 small craft advisory went out at Nov 11, 6:54 PM EST, 3 hours 56 minutes earlier.
Area forecast discussion, Nov 11, 6:54 PM EST, 3 hours 56 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
654 PM EST Tue Nov 11 2025
.SYNOPSIS...
Mainly dry, blustery and much colder today, although a few
passing flurries or snow showers are possible, especially in
the Berkshires. Blustery weather and below normal temperatures
continue through the rest of this week into Saturday with
nothing more than a few brief passing rain/snow showers. A
frontal system may bring mostly rain next Sunday with drier
conditions Monday.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Key Messages:
* Gusty winds continue into the evening before winding down
after midnight
* Chilly with sub-freezing lows and wind chills in the 20s.
Flurries and snow showers continued to diminish for most this
evening. Still expected to linger a bit longer towards the
Berkshires. Otherwise, clearing skies with diminishing winds
overnight. Tweaked forecast for the next few hours to reflect
observed trends.
Previous Discussion...
Gusty winds from this afternoon persist through about midnight
before an upper-level trough axis and associated low-level jet
shifts east this evening and overnight. Until then, gusty
westerly winds from 25-35 mph will be possible, with gusts up to
45 mph possible over Nantucket where a Wind Advisory remains in
effect.
Roughly after midnight, a mid-level ridge building over The
Northeast will allow the pressure gradient to relax and westerly
winds to diminish. While the stronger 20-30 mph gusts will come
to an end, westerly winds will still be steady around 10 mph.
Thus, with mechanical mixing and continued mid-level cloud
cover, we're not anticipating any significant radiational
cooling tonight. Nonetheless, the air mass still remains cooler
than normal and we can expect low temps near or below freezing
for most of southern New England. Steady winds will have the
"feels like" temperatures in the 20s for most of the region as
well.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
Key Messages:
* A few rain/snow showers early followed by a slight uptick in
temperatures
* Quiet weather tomorrow night with lows once again in the 30s
Weak short-wave energy may trigger a few rain showers over the
south coast, Cape, and Islands early tomorrow morning. Also
can't rule out a few snow showers over The Berkshires and
Worcester Hills, but most locations will remain dry. Southwest
flow develops allowing modest low-level WAA tomorrow afternoon
which will support 925 hPa temps rising a few degrees from
Tuesday. This will result in high temperatures about 5 or 6
degrees higher than Tuesday. Cloudy skies early will give way
to partial sunshine in the afternoon with steady west winds.
Skies then scatter out tomorrow night as west/northwest flow
ushers in a drier air mass. Low temps once again in the low to
mid 30s.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
Key Messages:
* Chilly temperatures continue through the weekend
* A low pressure system will bring rain and possibly frozen
precipitation to southern New England Saturday night through
Sunday
Thursday through Saturday
Deep northwest flow will support persistent CAA over The
Northeast Thursday through Saturday morning. This will continue
to support below normal temperatures with daily highs/lows in
the mid 40s/ upper 20s-low 30s respectively. A dry column and
surface high pressure should support more sun than clouds during
this time frame.
Saturday night through early next week
By Saturday night, model guidance is revolving a robust pulse of
short-wave energy digging southeast over The Great Lakes and
across The Northeast. This is expected to bring substantial
precipitation to southern New England with 24 hour ensemble mean
precipitation forecast coming in around a half inch.
Additionally, many solutions support a setup that would involve
warm air aloft overrunning shallow sub-freezing air at the
surface. This may introduce some precipitation type issues to
the forecast where we some locations may be dealing with a
wintry mix. Details are vague at this time range, but this will
be something to watch closely as we approach the weekend. Strong
cold air advection behind this system will continue to support
below- normal temperatures as we head into early next week. Stay
tuned for further details.
