Expect a partly to mostly cloudy sky and a low rain chance (10%). LOOKING AHEAD: Isolated showers for the work week as rain chances will be ~30%.

Vikings might have navigated foggy seas using crystals to analyze light from the sky, a trick similar to what honeybees do to stay on course on cloudy days, researchers suggest.

We’ll have a cloudy sky through the day with a few breaks in the clouds possible in the late afternoon. One or two showers can’t be ruled out today, but most of the area will be dry.
