.SYNOPSIS FOR THE COASTAL WATERS FROM SANDY HOOK NJ TO FENWICK
ISLAND DE AND FOR DELAWARE BAY...
Our significant heat wave will start to wind down tonight and
Thursday. The upper level ridge to our southwest will
gradually weaken and allow a back door cold front to track
though much of the forecast area Thursday into Friday. The front
will then push back to the north as a warm front on Saturday
and Sunday with high pressure remaining in control into Monday.
Another cold front looks to cross through the area on Tuesday.
