That bow echo is RACING off to the west. Chicago is about to get slammed and get slammed hard.

Per Weather Channel: "Chicago take shelter."
A night time PDS too!
Bad enough anywhere; but really bad possibility of damage in the Chicagoland...

They should make the "Extreme Wind Warning" an all-purpose product for winds of 100 mph or more, not just from tropical cyclones but also from convective thunderstorms/derechos.

They should make the "Extreme Wind Warning" an all-purpose product for winds of 100 mph or more, not just from tropical cyclones but also from convective thunderstorms/derechos.

They should, maybe even make it for 90 mph winds. Cause that can do more damage then a tornado or a hurricane.

I talked to two of my relatives in the western Chicago suburbs and they have power.
