[BOX Operations - NOAA Service Account]

Good morning,

We wanted to provide an update regarding the potential for scattered severe
thunderstorms and hot, humid conditions on Thursday. Attached you will find
our one-pager briefing and supplemental graphics.

*Severe Thunderstorms:* The greatest risk for severe storms is between 4 PM
and 10 PM, primarily across interior southern New England. The main threat
is damaging straight-line wind gusts, with large hail and a brief tornado
as a secondary threat. In addition, localized torrential downpours may
result in street flooding, especially in urban areas.

*Heat and Humidity:* Heat and humidity will peak during the early to
mid-afternoon, with heat index values in the upper 90s to lower 100s. As a
result, a Heat Advisory has been issued for northern Connecticut, northern
Rhode Island, and much of Massachusetts, excluding the Berkshires, south
coast, and Cape/Islands.

The next forecast update will be issued by *3 PM this afternoon*.

Please reach out if you have any questions or need further details.
