NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1243 AM EDT WED JUN 10 2026
AREAS AFFECTED...NORTHERN OH
CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE
VALID 100443Z - 100845Z
SUMMARY...A COUPLE OF BANDS OF VERY HEAVY SHOWERS AND
THUNDERSTORMS WILL BE CAPABLE OF LOCALLY BACKBUILDING AND OVER THE
SAME AREA GOING THROUGH THE NEXT FEW HOURS. VERY HIGH RAINFALL
RATES OF 1.5 TO 2.5 INCHES/HOUR, AND POTENTIALLY SOME SPOTTY 3 TO
4 INCH TOTALS MAY RESULT IN SOME INSTANCES OF MAINLY URBAN FLASH
FLOODING. THIS WILL INCLUDE SOME POTENTIAL IMPACT TO THE CLEVELAND
METROPOLITAN AREA AND ADJACENT SUBURBS.
DISCUSSION...THE LATEST GOES-E IR SATELLITE IMAGERY ALONG WITH
REGIONAL RADAR DATA SHOWS A COUPLE BANDS OF CONVECTION WITH HIGH
RAINFALL RATES IMPACTING PARTS OF NORTHERN OH. THE ACTIVITY OVER
THE LAST HOUR HAS BEGUN TO LOCALLY BACKBUILD AND TRAIN OVER THE
SAME AREA WHICH HAS BEEN HELPING TO YIELD SOME 1.5 TO 2.5
INCH/HOUR RAINFALL RATES.
THE CONVECTION IS BEING AIDED BY THE ARRIVAL OF A LOW-AMPLITUDE
SHORTWAVE TROUGH CROSSING THROUGH THE OH VALLEY WHICH IS
INTERACTING WITH A MODERATELY UNSTABLE AIRMASS CHARACTERIZED BY
MLCAPE VALUES AS HIGH AS 1500 J/KG, BUT ALSO HIGH PWS UPWARDS OF
1.8 TO 2.2 INCHES. THERE ARE FAVORABLE UPWIND PROPAGATION VECTORS
ALIGNED AGAINST THE PREVAILING LOW-LEVEL FLOW, AND THIS IS HELPING
TO FACILITATE SOME OF THE RECENT CELL-TRAINING TRENDS.
GIVEN THE SATELLITE AND RADAR TRENDS, SOME SHORT-TERM RAINFALL
AMOUNTS MAY REACH UP TO 3 TO 4 INCHES WHERE THE MOST PERSISTENT
CELL-TRAINING OCCURS. ALREADY SOME 1 AND 3-HOUR FFG EXCEEDANCE IS
SEEN ACROSS NORTHWEST OH. THIS ACTIVITY WILL LIKELY TEND TO
ADVANCE FARTHER OFF TO THE EAST AND MAINTAIN ITSELF AT LEAST FOR A
FEW MORE HOURS, BUT THIS WOULD SUPPORT IT POTENTIALLY GETTING INTO
THE CLEVELAND METROPOLITAN AREA OR AT LEAST ITS WESTERN AND
SOUTHERN SUBURBS. AS A RESULT, THERE WILL BE CONCERNS FOR AT LEAST
A THREAT OF URBAN FLASH FLOODING AS THIS EFFICIENT AXIS OF HEAVY
SHOWERS AND THUNDERSTORMS MOVES THROUGH.
