Troughing/Cyclonic Flow Aloft Will Prevail Across The U.S. This Period... As A Surface Cold Front -- Moving Across The Wrn Atlantic And Lingering Only Across S Fl -- Continues Shifting Away From The U.S. Mainland.
In The Wake Of This Front...Cool/Stable Continental Air Will Spread Across Most Of The Conus -- Precluding Appreciable Convective Threat Across Most Of The Country.
A Few Showers And Perhaps A Thunderstorm Could Occur Over S Fl
During The First Half Of The Period As The Front Moves Slowly Swd... But Potential Does Not Appear To Warrant Inclusion Of A Thunder Line At This Time.
