The National Weather Service thinks a cold front is coming through Friday night. They are probably right.
However it looks pretty nice, although there may be a few showers around on Friday. HIghs in 60's, lows in 50's, except in 40's Saturday night. Cloudy Friday, sunny and cool Saturday, if I am reading it right. Winds southwesterly, becoming northerly. Good that they will become northerly, as the truly chilly weather comes with the northwesterlies.
