Three Day Outlook

Created by the NWS Chicago WFO

It will be a cloudy and mild Halloween. During peak trick or treating hours, expect intermittent light rain or sprinkles at most, as shower coverage is expected to diminish vs. this morning in parts of the area. Daylight Saving Time will end tonight (2 AM Sunday), so don’t forget to set those clocks back! The first week of November will start on a mild and breezy note, followed by a period of wet weather centered on the midweek period.

This is a three day forecast graphic for northern Illinois and northwest Indiana.  Headline: Three Day Outlook.  Sub Headline: Halloween outdoor activities unlikely to be significantly affected… Seasonably mild.  Visit weather.gov/Chicago for more forecast details for your location.
