SATELLITE ANALYSIS AND TRENDS...WARM ADVECTION AHEAD OF UPSTREAM MCS
OVER STALLED OUT OLD FRONTAL BOUNDARY LIKELY TRIGGERED CONVECTION
WHICH HAS TRAINED FROM NW TO SE ACROSS OHIO DURING THE PAST COUPLE OF
HOURS. COLDEST TOPS AND BEST SATELLITE SIGNATURE HAVE LED TO AUTOMATED
SATELLITE ESTIMATES MAINLY IN THE 2.0-2.5" RANGE WITH LOCALIZED TOTALS
TO SLIGHTLY OVER 3" FOR APPROXIMATE WESTERN OHIO COUNTIES FROM VAN
WERT TO LOGAN/SHELBY WHICH INCLUDES SOME OF THE SAME REGION WHICH WAS
HIT BY VERY HEAVY RAINFALL LAST NIGHT. IMAGERY THROUGH 0945Z SHOWS
CONVECTION STILL AFFECTING PORTIONS OF THE AREA FROM VAN WERT TO LOGAN
WITH RE-INTENSIFICATION OF COLD TOPPED SATELLITE ENHANCEMENT OVER VAN
WERT/AUGLAIZE/ALLEN COUNTIES LEADING TO ESTIMATED RATES ONCE AGAIN
OVER 2"/HR CONTINUING OBVIOUS HEAVY RAIN THREAT THERE. IMAGERY ALSO NOW
INDICATES ADDITIONAL NEW CELL DEVELOPMENT IN EXTREME NW OHIO AND EVEN
FARTHER BACK TO THE NW INTO N AND NE INDIANA. CONCERN HERE IS THAT LEADING
EDGE OF MCS MOVING RAPIDLY TO THE EAST OR ESE WILL MERGE WITH THE NORTHERN
END OF THE OHIO/INDIANA LINE RESULTING IN PROLONGING THE CELL TRAINING
THREAT AND BRIEFLY INTENSIFYING RAINFALL RATES OVER NORTHERN INDIANA AND
ALSO EVENTUALLY AGAIN IN NW AND W CENT OHIO. INCREASING OBJECTIVE ANALYZED
SFC MOISTURE CONVERGENCE PARAMETERS IN REGION BETWEEN OHIO ACTIVITY AND
MCS SUGGEST THE AREA WILL CONTINUE TO FILL IN AS SEPARATE BATCHES LINK
UP. AS STATED EARLIER INTENSE RAINFALL RATES OF GREATER THAN 2"/HR ARE
LIKELY WITH THE STRONGEST CELLS AS EARLIER GPS PW AND GOES SOUNDER PW
DATA OF 2" OR HIGHER ALONG WITH HIGH SFC-DEWPOINTS GREATER THAN 70F
POOLED ALONG FRONT.
