KEY MESSAGE 1)

THIS FRONT WILL EVENTUALLY LIFT NORTH LATER TODAY AS A SHORTWAVE
TROUGH MOVES OUT OF THE MISSISSIPPI RIVER VALLEY AND INTO THE OHIO
RIVER VALLEY. SCATTERED TO WIDESPREAD SHOWERS AND THUNDERSTORMS
INCREASE DURING THE AFTERNOON AND LIKELY PERSIST THROUGH THE EVENING
AND INTO THE OVERNIGHT AS MOISTURE INCREASES EAST OF THE TROUGH
AXIS. LOCALLY HEAVY RAIN IS POSSIBLE WITH PWATS APPROACHING 2 INCHES
AND EFFICIENT WARM RAIN PROCESSES OCCURRING. OVERNIGHT, THE NOSE OF
A NOCTURNAL LLJ WORKS IN FROM THE WEST WHICH COULD LEAD TO A MORE
FOCUSED AXIS OF HEAVY RAINFALL SOUTH OF I-70. LIMITED INSTABILITY
SHOULD HELP MITIGATE A SEVERE STORM THREAT, ALTHOUGH A FEW STRONG
STORMS WITH GUSTY WINDS ARE POSSIBLE. PRECIPITATION ENDS SATURDAY
MORNING AFTER THE TROUGH AXIS MOVES EAST.
THE LATEST CAM GUIDANCE HAS BEEN HIGHLIGHTING POTENTIAL SWATHS OF 2+
INCHES OF RAIN SOUTH OF I-70 AND INTO NORTHERN KENTUCKY THIS
AFTERNOON THROUGH TONIGHT. CAM GUIDANCE, ALONG WITH THE FAVORABLE
METEOROLOGICAL SETUP FOR HEAVY RAIN, SUPPORTS ISSUANCE OF A FLOOD
WATCH SOUTH OF I-70 FOR THIS AFTERNOON INTO SATURDAY MORNING.
