Strong to severe thunderstorms will likely fire up from portions of the eastern Great Lakes to the interior Northeast into Monday, but a widespread outbreak of severe weather is not expected to accompany this system.

Current Radar, Watches and Warnings
The potential for severe storms is being driven by a strong upper-air disturbance and its associated surface frontal system, which is pushing through the Great Lakes region.

This system brought a few severe storms on Friday to the northern Plains. Hail as large as half-dollars fell in central North Dakota Friday afternoon and evening. Hail up to ping-pong-ball size was observed near Hutchinson, Minnesota, and a wind gust of 63 mph was measured near Grand Forks, North Dakota.
The storms then downed some trees and power lines in northern Wisconsin and Upper Michigan on Saturday.
Here's a look at what to expect through Monday.

Severe Weather Forecast

Through Sunday Evening
  • The low-pressure system will continue to push east, bringing strong to severe thunderstorms to portions of the eastern Great Lakes and perhaps the interior Northeast.
  • Threats: Damaging wind gusts and large hail are the primary concerns. However, an isolated tornado cannot be ruled out.
  • Cities: Indianapolis | Pittsburgh

Thunderstorm Forecast Through Sunday Evening
  • Scattered strong to severe thunderstorms are possible from the upper Ohio Valley northeastward into southern New York.
  • Threats: Sporadic damaging wind gusts and some hail are possible with any storms that turn severe.
  • Cities: Binghamton, New York | Cincinnati | Pittsburgh
Scattered thunderstorms will also stretch across much of the South into Monday, where an isolated severe thunderstorm may develop.
This low-pressure system will finally push off the East Coast Tuesday, with showers lingering in the Northeast. The cold front associated with this system will continue pushing through the South into midweek, bringing scattered showers and thunderstorms.
Locally heavy rain is also possible, which could bring the risk of flash flooding. This will particularly be the case in the South where tropical moisture is surging north from the Gulf of Mexico.
