... 
thunderstorms are not expected over the Continental U.S. Sunday. 


... 


Early Sunday a cold front will extend from a deepening surface low 
over the northeast states, along the Atlantic Seaboard, through the 
northern Florida Peninsula. While a few showers might accompany the front 
as it continues south across FL, shallow frontal forcing and 
relatively warm temperatures aloft suggest the thermodynamic 
environment will probably remain insufficient for lightning 
activity. Otherwise, a large area of high pressure will contribute 
to offshore flow and stable conditions over most of the country. An 
exception will be over the lower Great Lakes where a lightning 
strike or two cannot be ruled out with Shallow Lake-effect 
convection.
