[Weather] [2025.06.18 PM] NWS Boston Severe Storms and Heat on Thursday

[BOX Operations - NOAA Service Account]

Good afternoon,

There are no significant changes to the forecast this afternoon. We still
anticipate very hot and humid conditions, along with scattered severe
thunderstorms Thursday afternoon. Please see our one-pager briefing for
details, along with supplemental graphics.

*Severe Thunderstorms:*
The greatest risk for severe storms is between 4 PM and 10 PM, primarily
across interior southern New England. The threat diminishes farther east.
The main hazard is damaging straight-line wind gusts, with large hail and a
brief tornado as secondary threats. Localized torrential downpours may also
result in street flooding, particularly 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. 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 *10 AM Thursday*.

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