...SEVERE THUNDERSTORMS POSSIBLE SATURDAY AFTERNOON AND EVENING...

THE POTENTIAL EXISTS FOR STRONG AND SEVERE THUNDERSTORMS TO
DEVELOP SATURDAY AFTERNOON AND EVENING. PRIMARY THREATS LOOK TO BE
LARGE HAIL...DAMAGING WINDS...AND ISOLATED TORNADOES. THE
TIMEFRAME FOR SEVERE POTENTIAL LOOKS TO BE FROM AROUND NOON UNTIL
8 PM OR SO.

INITIAL SHOWERS AND THUNDERSTORMS FROM OVERNIGHT TONIGHT INTO
EARLY SATURDAY MORNING SHOULD MOVE OUT OF THE AREA BY AROUND 10
AM. BY LATE MORNING AND INTO THE AFTERNOON...THE ATMOSPHERE WILL
BECOME VERY UNSTABLE AND HAVE THE POTENTIAL TO DEVELOP SEVERE
THUNDERSTORMS. AGAIN THE PRIMARY THREAT IS LARGE HAIL BUT DAMAGING
WINDS AND ISOLATED TORNADOES WILL ALSO BE POSSIBLE...INCLUDING THE
POTENTIAL FOR A STRONG TORNADO OR TWO.

A LOT OF UNCERTAINTY STILL EXISTS FOR TOMORROW IN REGARDS TO HOW
WIDESPREAD STORM COVERAGE WILL BE...AND WHERE STORMS MAY DEVELOP
ACROSS THE REGION. THERE ARE A FEW LIMITING FACTORS THAT MAY HURT
STORM DEVELOPMENT DURING THE AFTERNOON. HOWEVER...WITH THE
ATMOSPHERIC CONDITIONS IN THE FORECAST FOR SATURDAY
AFTERNOON AND EVENING...SEVERE THUNDERSTORMS WILL BE POSSIBLE.
