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
