What forecasters said that day

The local office's own words before this extreme cold 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 extreme cold warning went out at Jan 22, 11:43 AM EST, 5 minutes earlier. Its key messages:

  • Lingering rain/snow mix through sunrise with another 0.5 inches of snow possible in the Worcester Hills.
  • Temperatures surge above normal today with gusty winds 25-35 mph. An arctic front moving through Friday brings another round of gusty winds 30-40 mph.
  • Arctic front arrives Friday night with dangerous cold and wind chills expected this weekend and into next week.
  • A late- weekend coastal storm will bring impactful snow to Southern New England Sunday into Monday.
Area forecast discussion, Jan 22, 11:43 AM EST, 5 minutes before
Area Forecast Discussion
National Weather Service Boston/Norton MA
1143 AM EST Thu Jan 22 2026

.WHAT HAS CHANGED...
As of 1142 AM, confidence continues to increase on arctic air
arriving Fri night into Sat followed by a high impact winter
storm Sunday into Monday. Headlines being worked on for the
early afternoon update.

&&

.KEY MESSAGES...

- Lingering rain/snow mix through sunrise with another 0.5 inches of
snow possible in the Worcester Hills.

- Temperatures surge above normal today with gusty winds 25-35
  mph. An arctic front moving through Friday brings another
  round of gusty winds 30-40 mph.

- Arctic front arrives Friday night with dangerous cold and wind
chills expected this weekend and into next week.

- A late- weekend coastal storm will bring impactful snow to
  Southern New England Sunday into Monday.

&&

.DISCUSSION...
Key Message 1...Lingering rain/snow mix through sunrise with
another 0.5 inches of snow possible in the Worcester Hills.

A wide swath of precipitation across most of southern New England
will move offshore around sunrise. While temperatures are already on
the rise, and the coastal plain above freezing, the remaining snow
will be confined to the interior higher terrain areas. Expecting up
to another 0.5 inches across the Worcester Hills.

Key Message 2...Temperatures surge above normal today with
gusty winds 25-35 mph. An arctic front moving through Friday
brings another round of gusty winds 30-40 mph.

Continued southwesterly flow and warm air advection helps warm 850
mb temperatures to -2C to -5C and 925 mb temperatures to -2C to +2C
this morning. This will allow surface temperatures to surge above
normal... afternoon highs in the upper 30s in the higher terrain to
low to mid 40s in the coastal plain. The pressure gradient begins to
tighten as another low pressure system move through the Great Lakes
and high pressure stalls over the Atlantic Ocean. Winds will pick up
during the afternoon hours as the land rapidly warms... expecting
gusts to increase to 25-35mph through this afternoon before calming
for the overnight period.

Expecting an arctic front to drop through southern New England by
Friday afternoon, rapidly increasing gusts to 30-40 mph with it's
passage.

Key Message 3...Arctic front arrives Friday night with dangerous
cold and wind chills expected this weekend and into next week.

The post frontal airmass Friday night into Saturday will be truly
arctic with the coldest air we've experienced in quite some time.
This intrusion of cold air will feature 850 mb temps as cold as -25
to -30C, several standard deviations below normal for late January.
This cold advection will result in a windy and frigid morning, the
coldest of the forecast period on Saturday. Low temps drop into the
single digits for most, and below zero in the Berkshires and
Worcester Hills. This is dangerous cold, especially when combined
with the gusty winds as a result of good mixing of a LLJ overhead.
Wind gusts 30-40 mph will make it feel like -15 to -25 in the
Berkshires where an Extreme Cold Watch has been issued. Elsewhere, a
Cold Weather Advisory will likely be needed for "feels like" temps
of -5 to -15F Saturday morning. Even in the afternoon highs will
only reach the single digits in the high terrain and mid teens
elsewhere. Temps only slightly moderate going into the second half
of the weekend. The Saturday morning period will also bring a high
risk of moderate freezing spray, and potentially heavy freezing
spray which would be a hazard for any crafts out on the waters.

Key Message 4...A late- weekend coastal storm will bring impactful
snow to Southern New England Sunday into Monday.

Turning our attention to the thing everyone wants to hear
about...are we getting a snow storm? Bottom line up front: it's
looking good. Confidence continues to increase that indeed we'll be
dealing with a moderate to high impact winter storm on Sunday and
Sunday night, perhaps lingering into Monday. Just how quickly it
exits remains more uncertain. Guidance has not made any big jumps
with the 00z run, continuing to indicate a good chance of much or
all of SNE to see 6+ inches of snow. That being said, we are still
over 3 days out from the onset of this system in New England and
that's an eternity in winter weather guidance world. As we've
emphasized over the last 48 hours, track of the low is key and many
solutions remain on the table. For what it's worth, the 00z EPS
ensemble guidance notably contracted the envelope of member low
locations (bunched around the favorable 70/40 benchmark). Even so it
remains best to approach this storm probabilistically, and the NBM
probability of over 6 inches of snow has gone up; now 60-70% in
northwest MA and over 90% in southeast MA. Probabilities of a foot
of snow or more 30-40% and 60-70% respectively. However, keep in
mind this a computer model probability that can and will still
change based on future trends. The ingredients are there for a
significant snow with a plume of subtropical moisture, a very cold
antecedent airmass, and strong forcing potential (tbd if it falls
within the DGZ for maximum fluffiness/snowfall rates etc, all
details we won't know until we get closer). The progressiveness of
this system is also still in question, but the heaviest snow at the
moment looks to be during the afternoon through early overnight
hours Sunday with lighter snow continuing well into Monday. One
fortunate aspect of this storm is that it doesn't look to bring very
strong/damaging winds with it (though it will be gusty over the
waters). Finally, any snow that falls isn't going anywhere fast
because the cold sticks around next week.
