98 mph? That would seem a pretty decent tornado for this country.

Looking at all the pictures of all the blown down trees and lost slates
I'd say a T2-3 on the Torro Scale or an F1 in that old Fujita money
that's 73-114 mph or a 'moderate / strong' tornado.

The straight line winds were all over the place yesterday, don't know
about Leeds but here there was an south easterly at the surface, a NE
wind around 2000 feet up and all the midlevel cunimb (remnants here!)
were moving in rather briskly from the SW - with that kind of shear
about there's a pretty good chance that something will spin up.
