DISCUSSION
KEY MESSAGE 1...
A WEAK COLD FRONT IS WORKING SOUTHEASTWARD ACROSS OH AT MIDDAY.
HIRES MODELS SHOW A MINOR INCREASE IN MOISTURE AND INSTABILITY
AHEAD OF THIS FRONT AS IT WORKS INTO THE MID OHIO VALLEY AND
PARTS OF WV LATER TODAY INTO TONIGHT. IT'S NOT MUCH, BUT A FEW
HUNDRED J OF CAPE WITH PWATS OF 1.25-1.50 INCHES SHOULD BE
ENOUGH TO KICK OFF ISOLATED TO WIDELY SCATTERED SHOWERS AND A
FEW THUNDERSTORMS. THESE MAY GET AS FAR SOUTH AS THE I-64
CORRIDOR BEFORE EVERYTHING STABILIZES OVERNIGHT LEAVING JUST
SOME PATCHY FOG TO PESTER LOCATIONS THAT GET AN EVENING
DOWNPOUR.
KEY MESSAGE 2...
MODELS CONTINUE TO POINT TO A POTENT DISTURBANCE MOVING ACROSS
THE OHIO VALLEY ON SUNDAY INTO MONDAY SPAWNING STRONG TO SEVERE
THUNDERSTORMS WELL TO OUR WEST DURING THE DAY SUNDAY. THERE IS
STILL A LOT OF UNKNOWNS REGARDING HOW WELL THESE STORMS HOLD
TOGETHER AS THEY MOVE EAST INTO OUR AREA LATE SUNDAY NIGHT. THE
ATMOSPHERE WILL BE STABLE EARLY, BUT WARMER, MORE UNSTABLE AIR
WILL ADVECT INTO THE REGION OVERNIGHT. THIS COULD BE A SIMILAR
SITUATION TO THURSDAY, WHERE TEMPS AND DEWPOINTS RISE
CONSIDERABLY OVERNIGHT ALLOWING STORMS TO REMAIN STRONG AS THEY
MOVE INTO THE REGION DURING WHAT IS NORMALLY A NOT SO FAVORABLE
TIME OF DAY.
UNCERTAINTY THEN BLEEDS OVER INTO THE DAY ON MONDAY AS SOME
MODELS, I.E. THE NAM, SHOW VERY LITTLE MORNING ACTIVITY WHICH
ALLOWS US TO RAPIDLY DESTABILIZE DURING THE DAY INCREASING THE
SEVERE WEATHER THREAT. OTHER MODELS SUCH AS THE RRFS GIVE MORE
PLAY TO THE MORNING ACTIVITY WITH NOT AS MUCH DESTABILIZATION
DURING THE DAY. THESE DETAILS WILL BE WORKED OUT IN TIME, BUT
WIDESPREAD SHOWERS AND THUNDERSTORMS ARE EXPECTED ON MONDAY,
PUSHING TO OUR EAST MONDAY NIGHT.
PWATS APPROACH 2 INCHES SO PLENTY OF MOISTURE AND REPEATING
ROUNDS OF SHOWERS/STORMS DEFINITELY POSE A FLASH FLOOD THREAT
JUST ABOUT ANYWHERE, BUT ESPECIALLY IN AREAS HIT HARD WITH
RECENT RAINFALL.
KEY MESSAGE 3...
SURFACE HIGH PRESSURE BUILDS INTO THE REGION MIDWEEK BUT WE
REMAIN CLOSE TO AN UPPER LEVEL TROUGH WHICH WANTS TO HANG OUT
OVER THE GREAT LAKES FOR THE REST OF THE WEEK. WITH THAT IN
PLACE, NO BIG WARMUP CAN OCCUR AND DISTURBANCES CAN PERIODICALLY
KICK OFF SOME SHOWERS AND THUNDERSTORMS. THIS APPEARS MOST
LIKELY AS WE GET TO FRIDAY AND SATURDAY.
AVIATION /06Z SUNDAY THROUGH THURSDAY/
SCATTERED SHOWERS WILL CONTINUE TO MOVE THROUGH WITH A COLD
FRONT EARLY THIS MORNING. SOME SHOWERS MAY CONTAIN RUMBLES OF
THUNDER AND SOME LIGHTNING. PATCHY VALLEY FOG IS EXPECTED TO
FORM THIS MORNING, AFTER THE SHOWERS PASS. EXPECTING THE LOWEST
VIS RESTRICTIONS ALONG THE OHIO RIVER AND POSSIBLY AT CRW WHERE
IFR OR LOWER IS POSSIBLE. SCT CLOUD COVER WILL LIKELY IMPEDE
FOG FROM BEING TOO DENSE ELSEWHERE.
VFR CONDITIONS WILL RESUME BY ~13Z AND WILL LAST THROUGH MUCH OF
THE DAY TODAY WITH SCT TO BKN MID TO HIGH-LEVEL CLOUDS BETWEEN
4,500 AND 20,000 FEET AGL.
SW'RLY WINDS WILL BE LIGHT TO CALM THIS MORNING, BECOMING LIGHT
AND VARIABLE BY THIS AFTERNOON THOUGH A W'RLY BIAS IS MORE
PROBABLE IN DIRECTION.
