The Latest On Saturday Storm Potential

After looking at the latest data, there will still be some strong "lift" in the upper atmosphere. In addition, the jet stream will provide plenty of shear.


In addition, the cold front will pass the area in the late afternoon.


Morning showers should briefly reduce the instability, however, the atmosphere should recharge by the afternoon. If this scenario pans out tomorrow, we could see some severe thunderstorms in the area. We will have more updates in the next 24 hours.

Update On Severe Potential

The atmosphere still looks marginally unstable heading into Saturday afternoon, however, there will be strong "lift" in the atmosphere to create a few thunderstorms. Right now it looks like the best chances for severe storms will be in our area and especially farther north. This is still a developing situation, so we will have more updates soon.

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.
