WITH ONLY WEAK FORCING EXPECT SCATTERED SHOWERS AND THUNDERSTORMS
ACROSS THE FORECAST AREA TO DIMINISH THIS EVENING WITH THE LOSS OF
HEATING. LOOKS LIKE PRECIPITATION MAY LINGER LONGEST IN THE SOUTHERN
ZONES BUT WILL ONLY CONTINUE IN THE FORECAST UNTIL MIDNIGHT.

BOUNDARY WILL SINK INTO SOUTHERN PART OF THE AREA OVERNIGHT BUT WILL
BE VERY WEAK. A SOMEWHAT DRIER AIRMASS WILL FILTER IN BEHIND THIS.
BUT IT WILL BE SHORT-LIVED. AS THE BOUNDARY FINALLY WASHES OUT AND
LOW LEVEL FLOW BECOME SOUTHERLY ON SUNDAY DEEPER MOISTURE WILL
RETURN. BUT WITH NO FORCING APPARENT WILL KEEP FORECAST DRY FROM
SATURDAY THROUGH MONDAY.

WILL CONTINUE TO SIDE WITH EUROPEAN MODEL WITH SLOWER MOVEMENT OF
THE NEXT SYSTEM INTO THE AREA. SO WILL BRING A CHANCE OF SHOWERS AND
THUNDERSTORMS IN MONDAY NIGHT SPREADING ACROSS THE ENTIRE AREA ON
TUESDAY. THIS NEXT FRONT MAY GET JUST FAR ENOUGH SOUTH TO BRING A
DRY WEDNESDAY BEFORE RETURNING NORTH INTO THE OHIO VALLEY THURSDAY
AND FRIDAY.
