The National Weather Service has given a serious tempest watch through Monday night for bits of eight states from Virginia to Connecticut, including eastern Pennsylvania and a lot of New Jersey.
The watch covers the Lehigh Valley and encompassing regions until 10 p.m. Rainstorms through the night could bring 70 mph wind blasts, hail the size of ping-pong balls and potentially cyclones, the weather conditions administration exhorts in the watch.
Watches mean circumstances are set up for extreme climate. Assuming that an admonition is given, that implies extreme weather conditions is occurring or up and coming.
