High Wind in Ohio, December 11 to 12, 2000

...Synoptic and mesoscale conditions on December 11th and 12th...An unseasonably cold arctic airmass spilling southward out of southern Canada on the 10th combined with a very strong upper level disturbance and upper level jet of 160 knots came together over the Midwest early on the 11th. Surface low pressure developed over Oklahoma early on the 11th and rapidly deepened as it lifted northeastward into central Indiana by late afternoon. A burst of heavy snow developed during the morning and quickly changed to heavy rain by late morning due to the tremendous warm air advection out ahead of the intensifing system. As the surface low continued to intensify and pull out into northern Ohio during the night of the 11th...strong gradient winds developed which caused some damage to trees and power lines over northwest Ohio with wind gusts of 59 mph reported in Putnam Ohio and 56 mph in Lima Ohio.
