Boston Weather: 38.0°F | Fair

Weather

Dry Today, Rainy Sunday

By Angela Zalucha
STAFF METEOROLOGIST

Boston’s weather this weekend won’t be much to write home about (but stay tuned and learn about tornadoes). Today and tonight will be sunny and continued dry. On Saturday, a low pressure system begins to move up from the Ohio Valley, and will bring us a good chance of rain through Monday. Temperatures will be slightly below average for this time of year, staying in the 50’s during the day and around 40 at night.

Given the recent deadly outbreaks of tornadoes in the Midwest, you might be wondering about the chances of Massachusetts getting hit. From 1950 to 1994, we have had 134 tornadoes total (or three per year on average), giving the state a rank of 35th overall. If you consider the number of tornadoes per square mile, we rank 13th. Massachusetts holds the title of having the first tornado sighted by European colonists (1671 in Rehoboth), as well as the first tornado-related death, which occurred in 1680 in Cambridge. New England has its own “mini” tornado alley, which extends from central Massachusetts to Vermont and is most active in July. New England has never had a tornado ranked F5 on the Fujita Scale (greater than 261 mph winds), but in 1953 an F4 (207-260 mph winds) struck Worcester, MA and killed 90 people.
