The severe weather threat for Severe Thunderstorm Watch 657
SUMMARY…Damaging winds will accompany a squall line as it surges
across Lake Erie into northern OH over the next 1-2 hours. Wind
gusts could exceed 50-60kt.
DISCUSSION…Well-defined MCS has evolved over southern ON/Lake Erie
late this evening. This mature complex of storms is now forming an
MCV along the north shore of Lake Erie, about 50mi north-northwest
of CLE. Over the last hour or so, this MCS has produced measured
wind gusts in excess of 50kt over southeast lower MI (54kt at KDET).
Latest radar data suggests the strongest surge is tracking southeast
near 50kt and will approach the southern shore of Lake Erie
(Cleveland metro) by 04z. Damaging winds can be expected along the
leading edge of this convection.
