KEY MESSAGE 1)
A MID/UPPER LEVEL TROUGH WILL MOVE EAST INTO THE GREAT LAKES AND OHIO
VALLEY REGION OVER THE WEEKEND. MODELS HAVE TRENDED A BIT FASTER
WITH THE ASSOCIATED COLD FRONT THAT WILL PUSH ACROSS THE AREA ON
SATURDAY. SOUTHERLY FLOW AHEAD OF THE FRONT WILL HELP US DESTABILIZE
THROUGH THE AFTERNOON, BUT WITH THE SOMEWHAT FASTER TIMING, THE
BETTER INSTABILITIES WILL BE ACROSS CENTRAL/EASTERN OHIO THROUGH
SATURDAY AFTERNOON.
A WEAKENING AREA OF SHOWERS AND EMBEDDED THUNDERSTORMS WILL LIKELY
MOVE INTO WESTERN PORTIONS OF OUR AREA LATE TONIGHT INTO SATURDAY
MORNING. THE STORMS WILL THEN BEGIN TO BECOME MORE ORGANIZED AS THEY
MOVE INTO THE MORE FAVORABLE AIRMASS ACROSS OUR EASTERN AREAS
HEADING INTO SATURDAY AFTERNOON. SOME STRONG TO SEVERE STORMS WILL
BE POSSIBLE DURING THE AFTERNOON ACROSS MAINLY OUR EASTERN AREAS BUT
THE OVERALL THREAT WILL BE DEPENDENT ON THE EXACT TIMING OF THE
FRONT. DAMAGING WINDS WILL BE THE PRIMARY SEVERE WEATHER THREAT.
STRONG CAA WILL DEVELOP BEHIND THE FRONT LATER SATURDAY AFTERNOON
INTO SATURDAY NIGHT. THIS WILL USHER IN A MUCH COOLER AIRMASS TO
START THE UPCOMING WEEK, WITH HIGHS ON SUNDAY AND MONDAY GENERALLY
IN THE 50S. SUNDAY NIGHT WILL BE THE COLDEST NIGHT AS TEMPERATURES
DROP INTO THE LOW TO MID 30S,LEADING TO THE POTENTIAL FOR SOME
FROST/FREEZE CONDITIONS.
