SYNOPSIS FOR NEW ENGLAND WATERS
A cold front moving E and SE over the area tonight will stall just E and SE of the area during Sun as an intensifying low pressure tracks NE along the front and passes just SE and then E of the area Sun night. A weak high pressure ridge moves in across the area Mon, followed by a strong cold front that will reach the coast late Mon, and then cross the waters Mon night. Surface troughs will move SE across the area Tue into Tue night with an area of high pressure building in from the W later Tue night into Wed. The high will then slide off to the SE of the waters late Wed and Wed night as a warm front develops and lifts N over the area. The warm front lifts N of the area early Thu, followed by another cold front moving across the waters later Thu and Thu night.
