FLASH FLOOD AND HEAVY RAIN THREAT DETAILS... EAST CENTRAL OHIO...NORTHERN WEST VIRGINIA PANHANDLE AND EXTREME SOUTHWEST PENNSYLVANIA REMAIN THE COUNTIES TO WATCH FOR FLASH FLOOD DEVELOPMENT. SOILS ARE STILL HEAVILY MOISTURE LADEN AFTER YESTERDAYS RAINS OF UP TO 2 TO 4 INCHES IN SOME COMMUNITIES. THUNDERSTORMS WILL BE MORE NUMEROUS NORTH OF INTERSTATE 70. SO THOSE COUNTIES NORTH OF INTERSTATE 70 IN THE WATCH AREA ARE THE MOST VULNERABLE TO FLASH FLOOD DEVELOPMENT. RAIN AMOUNTS IN MANY LOCATIONS WILL EXCEED AN INCH...AND UP TO 3 OR 4 INCHES ARE POSSIBLE. RAIN AMOUNTS EXCEEDING 1.5 INCHES IN AN HOUR OR 3 INCHES IN 3 HOURS CAN CAUSE THE RAPID FLOODING OF POOR DRAINAGE AREAS AND SMALL STREAMS. SEVERE WEATHER THREAT DETAILS... ANY STORM CAN HAVE WIND GUSTS OF OVER 30 MPH AND QUARTER INCH HAIL. STORMS ON THE SOUTHERN FRINGE OF THE BANDS OF THE STORMS ARE THE ONES WITH THE HIGHEST POTENTIAL FOR HAVING STRONG WIND GUSTS AND HAIL. AREAS NEAR AND SOUTH OF INTERSTATE 70 APPEAR TO THE MOST VULNERABLE TO THIS THREAT. WITH THOSE SOUTHERN STORMS...WIND GUSTS MAY EXCEED 60 MPH AND HAIL SIZES CAN EXCEED AN INCH. LIGHTNING CAN ALSO BE QUITE FREQUENT WITH THESE STORMS AS IT WAS YESTERDAY. WEATHER SCENARIO... A COLD FRONT FROM MICHIGAN WILL CUT THROUGH THE HUMID AND UNSTABLE AIR OVER THE UPPER OHIO VALLEY AND THUS CAUSE THUNDERSTORMS TO CONTINUE ACROSS THE REGION. AN EAST-WEST BOUNDARY NEAR INTERSTATE 70 HAS DEVELOPED WHICH MAY FOCUS STRONG THUNDERSTORM IN THAT PART OF THE OHIO HEADWATERS REGION. THE ENTIRE OHIO HEADWATERS REGION IS UNSTABLE...SO THUNDERSTORMS CAN BE STRONG. AREAS SOUTH OF INTERSTATE 70 MAY BECOME THE MOST UNSTABLE IF SURFACE TEMPERATURES REACH THE UPPER 80S OR 90. AN EAST-WEST BOUNDARY CLOSE TO INTERSTATE 70 HAS DEVELOPED...SINCE AREAS TO THE NORTH ARE WET AND CLOUDY AND AREAS TO THE SOUTH ARE SUNNY AND WARMING RAPIDLY. THIS MAY BECOME THE REGION WHERE THE STRONGEST THUNDERSTORMS FOCUS. THE THUNDERSTORMS CAN ALSO OCCUR IN SERIES THIS AFTERNOON AND EVENING WHICH MEANS REPEATED DOWNPOURS ARE POSSIBLE...WHICH IS ANOTHER REASON FOR MAINTAINING THE FLASH FLOOD WATCH. THE THREAT FROM THUNDERSTORMS WILL DIMINISH LATE TONIGHT AFTER THE FRONT HAS PASSED THROUGH. SKYWARN ACTIVATION NOTES... SKYWARN OBSERVERS ARE REQUESTED TO CALL WITH ANY RAIN AMOUNTS OF BETTER THAN 1 INCH IN AN HOUR OR TOTALS OF 2.5 INCHES SINCE 7 AM.
