I'm showing about 120kt gate to gate shear which equates to roughly 135mph so I dont doubt it.

Re: June 4-7: Severe weather outbreak
My son called me here in Arizona, and said he watched the tornado in Lansing. He took pictures of it. He said it was the most unbelievable sighting he's seen. It went right down Bernice Rd and headed towards Indiana. (Munster I believe)
All the power is off in that area too.

AND LIFT ASSOCIATED WITH A BROAD 40 TO 50 KT LOW-LEVEL JET WILL
SUSTAIN THE LINE THROUGH THE OVERNIGHT HOURS.
THE LATEST REGIONAL PROFILERS CURRENTLY SHOW 40 TO 50 KT OF VERTICAL
