And a chance of what?

As we were out and about this morning:

J: It's supposed to be wet like this tomorrow, too.
C: Hmmmm.
J: This morning, the radio said we'd have scattered showers today.
J: Tomorrow, it is supposed to be like this, plus ice.
C: What? Ice? It's probably too warm for ice just yet.
J: Well, that's what he said on the radio: isolated showers.
