A WINTER WEATHER ADVISORY is posted for the region from Sunday morning through early Monday morning. A light wintry mix will spread slowly south to north across the region during Sunday morning and continue on and off throughout the daytime. Then as temperatures drop tomorrow night the mix will change to a light snow before tapering off by early Monday morning. During the daytime hours of Sunday any accumulation of snow, sleet or ice will be light but nonetheless slippery roads and sidewalks will develop. Snow fall accumulations on Sunday night will also be light generally less than 1" for most with a couple of inches across the higher terrain west and especially to the east of the Hudson River Valley.
