AREAS AFFECTED...NRN OH...FAR SERN LOWER MI
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 062248Z - 070045Z
A THREAT FOR ISOLATED DAMAGING WINDS AND PERHAPS A BRIEF TORNADO
SHOULD PERSIST FOR THE NEXT FEW HOURS WITH SLOW-MOVING E/SEWD
PROPAGATING SEMI-DISCRETE CELLS. THE PROBABILITY OF A WW ISSUANCE BY
01Z IS 20 PERCENT.
DISCRETE TSTMS CENTERED OVER FULTON COUNTY OH AND SERN LENAWEE
COUNTY MI HAVE EXHIBITED WEAK TO MODERATE LOW-LEVEL ROTATION DURING
THE PAST HOUR. ALTHOUGH LOW-LEVEL FLOW IS WEAK PER AREA VWP
DATA...STRONG MID/UPPER-LEVEL WLYS HAVE RESULTED IN 35-40 KT
EFFECTIVE SHEAR AND MAY CONTINUE TO SUPPORT OCCASIONAL SUPERCELL
STRUCTURES. WITH POOR 700-500 MB LAPSE RATES /AROUND 5-6 DEG C PER
KM/...TSTMS WILL LIKELY STRUGGLE TO PRODUCE SEVERE HAIL. BUT GIVEN
LOW TO MIDDLE 70S SURFACE DEW POINTS...MODERATE BUOYANCY SHOULD BE
SUFFICIENT FOR A SHORT-TERM THREAT OF ISOLATED WET MICROBURSTS AND A
BRIEF TORNADO.
