The beautiful weekend weather just couldn't last. While clear, sunny skies remain over New England, a low-pressure system spinning up from the Southeast has brought clouds over the mid-Atlantic.
An area of high pressure that dominated from late last week through the weekend is now centered near Maine, slipping off the coast. The area had blocked clouds from moving into the region.
"ALL GOOD THINGS MUST COME TO AN END...AND SO WE SAY FAREWELL TO THE FINE WX OF THE PAST FIVE DAYS," National Weather Service meteorologists wrote in a morning forecast discussion.
The low pressure system is expected to track up the East Coast this week, with a cold front coming in for the weekend, the discussion continued.
