Satellite imagery with lightning data overlay showing a line of strong to severe thunderstorms moving across the Florida Peninsula. Severe Weather Watches are currently in effect across the state. Also of note is the slowly departing Nor’easter.

A series of strong upper level low pressure systems can be seen moving eastward along strong jet stream winds. These systems will initially impact western Canada and northwest U.S. before moving across the northern Plains and Great Lakes.

Amazing animation of former Major Hurricane Sam transitioning into an extratropical cyclone over the North Atlantic Ocean. Atlantic basin hurricanes often transition into extratropical cyclones over this region.
