Quiet, sunny weather persists
It will be a pleasant early fall weekend, thanks to a high pressure system that will remain in control of our weather. The high temperatures will be near or slightly above the climatological normal value of 69°F, while the low temperatures will likely be slightly cooler than the climatological normal value of 54°F, thanks to mostly clear skies that allow for strong radiative cooling at night. It is unlikely we will receive rain before the end of the month on Monday, so we will fall far short of the 3.44” that is the climatological average for September precipitation (so far, we’ve received 2.21”). Looking farther ahead, a coastal low will pass to our east on Monday night. There is significant model spread in the position of the low, but there is a chance that rain will impact the Cape and Islands.
