Warmer weekend into early week. Cold sea surface and inland water temperatures relative to air temperatures this weekend could make lake/ocean recreation dangerous. Next week, temperatures get even warmer with some 90F readings possible in southern NH on Tuesday. Thunderstorms, some potentially strong, are possible in the afternoon on Tuesday and Wednesday as two frontal boundaries near and cross the region from the north.
