[Weather] [03.29.23 PM] NWS Boston EM Briefing: Possible Snow Squalls Late Tonight to Overnight

[BOX Operations - NOAA Service Account]

Good afternoon:

Following is an update regarding the potential for low-visibility snow
showers or possible snow squalls.

Forecast remains little changed from what was briefed this morning.

Timing continues to be centered around late tonight to early overnight,
from 9 PM Wednesday to 3 AM Thursday. In this period, we anticipate initial
rain to change to a short, quick-hitting period of moderate to heavy snow
which has the potential to reduce visibility significantly and could result
in slippery untreated roads (especially secondary and side streets). Snow
amounts themselves will not be significant and in most cases will be less
than an inch - it s the rapid reduction in visibility and changing road
conditions which will pose the greatest hazard.

Weakening trends are also anticipated as the cold front producing these
conditions moves eastward. Thus, the greatest confidence in potential for
adverse impact continues to be mainly west of Worcester, with reduced
confidence in impacts into eastern MA and RI.

Unless there are significant changes, this will be the final briefing
regarding this weather situation. However we ask you to monitor for
short-fused Special Weather Statements, or Snow Squall Warnings in a case
of visibility falling to near zero in bursts of heavy snow, which could be
needed tonight into the overnight.

Thank You!

Meteorologists: Andrew Loconto and Matthew Belk
