shifting E and SE of the area late Mon night into Tue. A strong
cold front will approach the area from the W and NW Tue night,
then move quickly SE across the area on Wed. The front will clear
S and E of the waters Wed night into early Thu as strong high
pressure builds E and SE toward the area from the Great Lakes.
High pressure will move SE over the waters later Thu into Fri,
before passing just E of the area Fri night as a low pressure
system organizes to the S of the waters.
