AREAS AFFECTED...PORTIONS OF NORTHERN OHIO INTO FAR WESTERN

CONCERNING...SEVERE THUNDERSTORM WATCH 649...
VALID 032243Z - 040015Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 649
CONTINUES.
SUMMARY...THE THREAT FOR PRIMARILY DAMAGING/SEVERE WIND GUSTS
CONTINUES ACROSS PORTIONS OF SEVERE THUNDERSTORM WATCH 649.
DISCUSSION...AN ONGOING MCS CONTINUES TO PERSIST ACROSS PORTIONS OF
NORTHERN OHIO AS OF 2240 UTC, WITH WIND GUSTS OF 60 AND 62 MPH
RECENTLY MEASURED IN CLEVELAND/ELYRIA, OH, VICINITY. RECENT RADAR
IMAGERY FROM KCLE INDICATES THAT THE SYSTEM OUTFLOW HAS OUTPACED THE
DEEPER CONVECTIVE CORES ALONG THE SOUTHWESTERN FLANK OF THE MCS BUT
REMAINS MORE CO-LOCATED WITH THE DEEPER UPDRAFTS FARTHER TO THE
NORTHEAST. HOWEVER, THE DOWNSTREAM ENVIRONMENT ACROSS NORTHEASTERN
OHIO IS CHARACTERIZED BY COOLER SURFACE TEMPERATURES AND INCREASED
STATIC STABILITY OWING TO THE PASSAGE OF PRIOR CONVECTION, WHICH IS
LIKELY CONTRIBUTING TO A WEAKENING OF THIS MCS AS INDICATED BY
RECENT LIGHTNING TRENDS. THUS, SOME UNCERTAINTY EXISTS REGARDING THE
DOWNSTREAM INTENSITY OF CONVECTION, BUT AT LEAST SOME RISK FOR
PRIMARILY DAMAGING/SEVERE WIND GUSTS IS LIKELY TO PERSIST DOWNSTREAM
ACROSS PORTIONS OF NORTHERN/EASTERN OHIO FOR AT LEAST ANOTHER 1-2
HOURS.
