URGENT - IMMEDIATE BROADCAST REQUESTED

Severe Thunderstorm Watch Number 484

NWS Storm Prediction Center Norman OK

130 PM EDT Thu Jul 3 2025



The NWS Storm Prediction Center has issued a



* Severe Thunderstorm Watch for portions of 

  Connecticut

  Massachusetts

  Northern New Jersey

  Southern New York

  Northeast Pennsylvania

  Rhode Island

  Coastal Waters



* Effective this Thursday afternoon and evening from 130 PM until

  1000 PM EDT.



* Primary threats include...

  Scattered large hail and isolated very large hail events to 2

    inches in diameter possible

  Scattered damaging wind gusts to 70 mph possible



SUMMARY...Thunderstorm coverage and intensity should increase this

afternoon across the region amid strengthening large-scale ascent

and airmass destabilization. Moderate to strong buoyancy coupled

with moderate vertical shear will support organized storm structures

capable of large hail and damaging gusts. Large hail will be the

primary risk with the early-stage cellular development while strong

winds will be more likely once storms transition towards a more

linear mode.



The severe thunderstorm watch area is approximately along and 75

statute miles north and south of a line from 40 miles northwest of

Williamsport PA to 25 miles east of New Bedford MA. For a complete

depiction of the watch see the associated watch outline update

(WOUS64 KWNS WOU4).



PRECAUTIONARY/PREPAREDNESS ACTIONS...



REMEMBER...A Severe Thunderstorm Watch means conditions are

favorable for severe thunderstorms in and close to the watch area.

Persons in these areas should be on the lookout for threatening

weather conditions and listen for later statements and possible

warnings. Severe thunderstorms can and occasionally do produce

tornadoes.
