[Weather] [2021.09.15 930 AM] NWS Boston EM Briefing - Severe Weather Possible Late This Afternoon into Tonight

[BOX Operations - NOAA Service Account]

Hi everyone,

The Storm Prediction Center's "Slight Risk" area has expanded slightly
farther east, to include northeast MA, the city of Worcester, and the city
of Hartford. The tornado risk has also slightly expanded, to include more
of interior MA, with greatest risk from the northern Berkshires to the
northern Worcester hills.

Not much has changed in terms of the overall scenario or timing. Expect a
line of storms to develop around 3-4 PM and move eastward across western
and central portions of the region during the early evening, weakening as
it heads east.  We will also be keeping an eye out for isolated flash
flooding, due to any storms traversing the same areas.

There is a chance that a portion of the region could be upgraded to an
Enhanced Risk by SPC on the 1230 PM update.  Stay tuned.
