The weather fell in love with Northern Illinois and Indiana when the pressure lines formed a heart shape right over them Friday morning.

The lines on surface analysis charts show constant pressure, and can form all sorts of interesting patterns. But it's not everyday we see a heart.

This area of high pressure also brought some unseasonably cool temperatures this morning, where people woke up to areas of frost right in the middle of August!

Guess you can say the weather was a bit cold-hearted today.
