Generally nice weather will dominate for the final day and a half of astronomical Summer. The exception will be Cape Cod & Nantucket which will be under a canopy of clouds and may see a little light rain. This is from the front that gave the wind and rain Tuesday night and early Wednesday, which has been hanging around just offshore since then. A small ripple of low pressure is responsible for the backward jog of this area. By early Saturday, this area will be back out to the east again as a new cold front approaches from the west. Timing of this front suggests most of the clouds and any shower risk will take place between midnight Saturday night and shortly after dawn Sunday morning. This front will move right along so that weather should improve quickly on Sunday. A cool shot of air will max out on Monday which will feel very much the new season. High pressure will move in at that time and then dominate a good portion of next week with a dry stretch of weather expected, with some warming likely as well.
Autumn begins at 10:49AM Saturday, which ironically will be the warmest day of the next several.
