...NO SEVERE THUNDERSTORM AREAS FORECAST...
No severe thunderstorms are expected across the United States today.
A cold front will drift slowly south through the remainder of south
Florida today. Showers and isolated thunderstorms will remain
possible within the frontal zone, especially as the atmosphere
destabilizes during the afternoon.
...lower Great Lakes...
A large area of arctic high pressure will spread sewd over the Great
Lakes where lake temperatures are relatively warm (45-50F). This
will contribute to steepening lapse rates and destabilization, with
lake effect convection possibly becoming deep enough for a few
lightning strikes, especially downstream from lakes Ontario and Erie
where lake-parcel trajectories will be maximized.
