SATELLITE ANALYSIS AND TRENDS...LATEST IR AND VIS IMAGERY SHOWS WARM
TOP CELLS CONTINUING TO TRAIN ACRS THE AREA FM GEAUGA/ASHTABULA/
TRUMBULL COUNTIES OH TO VENANGO COUNTY PA. MOST OF THE TRAINING SINCE
19Z HAS OCCURRED OVER ASHTABULA AND CRAWFORD COUNTIES. AUTOMATED STLT
ESTIMATORS UNDERDOING AMOUNTS DUE TO WARM TOP NATURE OF THE CONVECTIVE
CLOUD TOPS WHICH HAVE RANGED FM -34C TO BRIEFLY AS HIGH AS -56C. ONE
OF THE AUTOMATED ESTIMATORS DOES INDICATE 1.3" OVER NE OH TO 2.3" OF
RAIN THRU 23Z OVER CRAWFORD. TAKING INTO ACCOUNT THE UNDERESTIMATION BY
AUTOMATED ESTIMATORS WITH WARM TOP EVENTS..ALONG WITH THE OCCASIONAL CELL
MERGERS THAT HAVE OCCURRED THIS AFTN/EVE..MANUAL STLT ESTIMATES INDICATE

ANIMATION INDICATES THAT THE OUTFLOW FM THE CNVTN CURRENTLY AFFECTING
W CENTRAL TO CENTRAL OH..WILL EVENTUALLY REACH N CENTRAL AND NE OH. THE
POTENTIAL EXISTS THAT THIS COULD FURTHER ENHANCE THE CNVTN NOW ONGOING
OVER NRN/NERN OH. IF THIS SCENARIO PANS OUT..THAT THE CELL TRAINING
SITUATION WILL OVER NE OH/NW PA WILL BE SIGNIFICANTLY PROLONGED..WITH
