...DISCUSSION...
CONSIDERABLE UNCERTAINTY LINGERS REGARDING SHORT WAVE DEVELOPMENTS
ASSOCIATED WITH A PAIR OF STRONG UPPER JETS EXPECTED TO TRAVERSE THE
U.S. DURING THIS FORECAST PERIOD. HOWEVER...THE SPREAD AMONG THE
VARIOUS MODEL ENSEMBLE DATA MAY BE DECREASING A BIT CONCERNING
CONVECTIVE POTENTIAL ASSOCIATED WITH IMPULSES THAT COULD IMPACT THE
SOUTHEASTERN STATES LATE THIS WEEKEND INTO EARLY NEXT WEEK. WHILE
THE RISK FOR A SIGNIFICANT SEVERE WEATHER EVENT STILL DOES NOT
APPEAR OUT OF THE QUESTION...PARTICULARLY IN A CORRIDOR ACROSS PARTS
OF CENTRAL/SOUTHERN MISSISSIPPI AND ALABAMA...AND GEORGIA INTO THE
CAROLINAS LATE THIS COMING SUNDAY INTO MONDAY...PROBABILITY OF
OCCURRENCE APPEARS LOW AT THE PRESENT TIME. CONSIDERABLE
THUNDERSTORM ACTIVITY STILL APPEARS POSSIBLE...THOUGH ...AND THE
RISK FOR SEVERE STORMS IS PROBABLY NOT COMPLETELY NEGLIGIBLE.
