It’s a classic September sky above Minnesota today.

Our breezy and cooler northwest flow, combined with still potent early September sunshine is perfect for billowing cloud towers this afternoon.

A few of those puffy clouds will build high enough to produce some isolated passing showers. You may even hear a thunder clap in the stronger cells.
