The big warm up will occur Saturday when highs are expected to climb into the lower 80s. South and southwest winds will blow ahead of a cold front that should pass Saturday night. A few isolated showers will be possible late Saturday into Sunday. Sunday's highs should stay in the lower 70s.

The "trick or treat" forecast is looking pretty good for Hampton Roads. Skies will be partly to variably cloudy and temperatures will fall through the 70s. There will be a chance for an isolated shower later Saturday night.
