SATELLITE ANALYSIS AND TRENDS...FIRST FEW GOES-EAST IMAGES SINCE
ECLIPSE HAVE SHOWN AN INCREASE IN SATELLITE SIGNATURE FOR HEAVY RAINFALL
OVER THE DISCUSSION AREA. AUTOMATED SATELLITE ESTIMATES FOR THE PAST
SEVERAL HOURS ARE INDICATING ROUGHLY 1.5-2.5" TOTALS ALONG APPROXIMATE
AXIS STRETCHING FROM NEAR FT WAYNE INDIANA TO AROUND CRAWFORD COUNTY OF
CENTRAL OHIO. LOCALIZED TOTALS OF AT LEAST 3.0-3.5" WERE INDICATED FROM
PUTNAM(OH) TO CRAWFORD(OH) COUNTY.
.
CONCERN HERE IS THE CONTINUING REDEVELOPMENT ALONG THE WESTERN END OF
THE ACTIVITY OVER NE INDIANA WHICH CONTINUES TO TRAIN ALONG THE SAME
GENERAL AXIS. DO NOT SEE ANY IMMEDIATE END TO THIS FOR AT LEAST THE NEXT
1-2 HOURS SO A MORE SERIOUS SITUATION COULD EVOLVE. SATELLITE IMAGERY
TRENDS THROUGH 0715Z SHOWS SUBTLE CLOUD TOP COOLING OCCURRING IN NE
INDIANA AS WELL AS W CENT OHIO SO EMBEDDED LOCALIZED RAINFALL RATES OF
1.5"-2.0"/HR WITH THE STRONGEST CELLS SHOULD STILL BE OCCURRING. 30-40KTS
OF MOIST WSW LOW LEVEL INFLOW OVERRUNNING STALLED OUT SFC BOUNDARY IS
CERTAINLY THE PRIMARY CONTRIBUTING FACTOR FOR THIS SETUP. THE LATEST
RUC ANALYSIS/SHORT RANGE FORECAST SHOWS GOOD MOISTURE TRANSPORT STILL
OCCURRING ACROSS THE REGION WITH 00Z RAOB DATA AND LATEST GPS PW DATA
SHOWING VALUES IN EXCESS OF 2" PROVIDING ENVIRONMENT FOR VERY EFFICIENT
RAINFALL PRODUCING CELLS. WATER VAPOR IMAGERY OUT OF ECLIPSE PERIOD ALSO
SEEMS TO NOW INDICATE SOME MID/UPPER LEVEL CONNECTION FROM THE REMNANTS
OF ERIN CURRENTLY OVER S IL/S IN/W KY AND THE UPSTREAM MCS OVER PORTIONS
OF IA/MO/IL. PERHAPS SOME RELATIVELY MINOR UPPER LEVEL SPEED MAX MOVING
TO THE NE OF THE REMNANTS OF ERIN AND/OR EAST OF THE UPSTREAM MCS HAS
ADDED A BIT TO THE OVERALL LIFT FOR THE INDIANA/OHIO ACTIVITY.
