SUNDAY

Tomorrow is shaping up to be a beautiful fall day, but emphasis on "fall" because it will be colder than average. Expect ample sunshine with temperatures climbing into the mid 50s. On average temperatures are in the mid 60s this time of the year. The wind tomorrow will be lighter, from the north at about 10 mph.

THE WEEK AHEAD: GORGEOUS FALL COLOR

Most of next week looks dry with high temperatures back in the 60s. But there will be a storm offshore that could bring Long Island extra clouds and breezy conditions early next week. However, sunshine returns for the end of the week and no rain is expected. This should bring out some absolutely gorgeous fall colors.
