=== NWS Regional Summary - 543 AM EDT SUN MAY 7 2006 ===
Skies dawned clear across most areas early this morning, with just a few
clouds over Cape Cod and the islands. At 5 am, temperatures ranged from 33° in
Orange to 51° at Chatham. With high pressure building across southern New
England today, skies will be sunny. A few clouds may form along the coast as
sea breezes develop, keeping temperatures a bit cooler there. High will be
mainly in the 60s. Clear skies and light winds will be the rule across the
region tonight. This could lead to patchy frost forming across the normally
colder locations. Since the average date of the last spring freeze has passed
across southern areas, some locations may need a frost advisory tonight. This
includes interior portions of southeastern Massachusetts and northeast
Connecticut, and possibly Marthas Vineyard and the lower Cape. The high will
hang strong across the region on Monday, though clouds will be increasing
during the day. Highs will again be in the 60s. Low pressure will slowly
approach from the mid Atlantic coast during Tuesday, bringing the threat of
rain. An area of high pressure will build across New England today and
tonight, then will move off the coast during Monday. This high will stall
offshore through mid week. Low pressure will form over the Carolinas today,
then will try to push northward Monday and Tuesday.
