.DISCUSSION...
High pressure will extend across the Mid-Atlantic into New
England through Sunday, with the hottest conditions of the week
expected Sunday. A cold front will push south across the area
Sunday night into Monday. Thereafter, this boundary will stall
nearby through Wednesday, which allows for below normal
temperatures and increasing rain chances. This cold front tracks
south of the region later in the week while high pressure builds
to the north.
