Severe Thunderstorms Saturday?

A few thunderstorms will be possible on Saturday as a cold front passes the area. The front will be along I-81 during the late afternoon.

Jet stream winds will provide strong speed shear (winds increasing with height).

And there should be enough instability in the atmosphere to support thunderstorm development.

One limiting factor on Saturday will be cloud cover, which will reduce instability. In addition, there could be too much shear, which would inhibit thunderstorm development.

This is something we are watching closely and will have more updates in the next couple days.
