 The same surface high will then provide pleasant weather tomorrow, perhaps starting with a touch of valley fog, but with mostly sunny skies and light winds after that and highs mainly from the upper 60s to mid-70s. Saturday's highs will be similar, but winds will pick up, doing so ahead of large low pressure that will lift out of the Great Lakes. It's warm front, spreading showers in from our west on Saturday, and then a steadier rain becoming likely Saturday night, along with very mild overnight temperatures.
