An area of high pressure is building in tonight and will continue during the day on Saturday, which will bring sunny and cool temperatures for Halloween. A warm front will then move through the area late Saturday night/early Sunday morning, which will bring mostly cloudy conditions overnight Saturday and during the day on Sunday. There is a slight chance for some showers Sunday night and during the day on Monday, but at this point, neither time frame looks like a washout.
Remember that Daylight Saving Time ends Sunday morning at 2am. Make sure you set your clocks BACK 1 hour before you go to bed Saturday night!
