.DISCUSSION...
Canadian high pressure will slowly pull away from the Atlantic
coast today. At the same time, a stalled front is expected to
approach from the Great Lakes before crossing the region as a cold
front by early Friday. This will come with increasing storm
chances along with a brief period of warm temperatures and
increased humidity. High pressure crosses the northeastern U.S. on
Saturday before a frontal system remains nearby on Sunday into
early next week. This brings increasing shower chances across the
area along with a marked cooling trend starting Monday.
