[Weather] [2025.12.02 AM] NWS Boston EM Briefing: Winter Storm Today into Tonight

[BOX Operations - NOAA Service Account]

Good morning,

Please find attached an updated one-page briefing regarding the winter
storm expected to impact the region Today and tonight.

*What's Changed:*
Snow totals have slightly changed since the last update, however, these
were not significant changes. Confidence in the location of the heaviest
snow and where the greatest impacts will be has continued to increase.

*Timing:*
No changes to timing from previous briefing. See attached graphics for more
details.

*Lingering Forecast Challenges:*
Although overall forecast confidence in the storm’s amounts and impacts has
increased, a few questions remain:

1. The northward extent of warmer air is contributing to some uncertainty
in the exact position of the rain-snow line, which will dictate snow totals
particularly in NE MA.
2. Moderate confidence in minor snow accumulation along the I-95 and part
of the northern I-495 corridor this evening/tonight. Lower confidence
exists in the exact timing for this snow. This ties back into the
uncertainty in the location of the rain-snow line.

This will be the final briefing for this event barring any significant
changes.

Thank you,
Meteorologists Caity Mensch and Candice Hrencecin
