Tonight our temperatures will drop into the 50s and 60s before another warm day on Monday for many of us. We will turn sharply cooler at the coast as a backdoor cold front slides through eastern New England. Ahead of it, an isolated thunderstorm is possible. Conditions on the water look generally quiet, although a bank of low clouds and patchy fog will accompany the backdoor front during the afternoon, creating pockets of reduced visibility on the ocean.
