Weather

By Roberto Rondanelli
STAFF METEOROLOGIST

The transition between winter and summer is much awaited. The greatest rate of change in sunlight will occur during the next month as we go from 12 hours of sunlight on March 20 to almost an hour and a half more for the same day in April. However, cloudiness won’t necessarily decrease with respect to wintertime. In Boston, February has on average 8 clear days and 13 cloudy days, whereas May has only 6 clear days and 15 cloudy days.

As for this week, the warm and moist trend will continue today. The low depicted in the map and the cold front associated with it were strong enough to produce a very active line of thunderstorms extending through part of the Midwest yesterday, causing some tornado warnings. As the front moves through our region, the line of thunderstorms and/or heavy rain will hit today before sunrise. Later today, temperatures will drop, along will cloudiness.
