Our long advertised and long anticipated shot of some fall temperatures is upon us, much awaited by many after the late run of heat.

Coolest temperatures in seven months.

Rainfall from Michael across the metro area ranged 2-6 inches, max wind gusts in the NW suburbs 25 mph on the SE side 40 mph with isolated higher gusts.

Michael was near a CAT 5 storm at landfall near Mexico Beach Florida with max winds aloft 155 mph, at the surface an official wind gust of 129 mph at Panama City airport equivalent to an F-2 tornado.

Seeing some of the hardest hit areas in the Florida Panhandle have homes wiped away down to the slab.

The central pressure of Michael was 919mb at landfall, 3rd deepest pressure in history.

A change of air mass is right on the heels of Hurricane Michael. Breezy today with a clearing trend then some free air conditioning with open window weather.
