St. Valentine's Day falls in February, which is high time for snow in Massachusetts. In 2007, a storm heaped snow on much of the East Coast. It even formed tornadoes on the southern part of the storm system, though these were EF2 or less. Boston largely escaped the snow this storm dropped just about everywhere nearby. The city was not as lucky during the first St. Valentine's Day Blizzard in 1940. That storm had a bigger effect on Boston and nearby towns.
The 1940 St. Valentine's Day Blizzard dropped about 12 to 18 inches on the city. This is a significant amount of snow, though hardly as bad as legendary storms like the tragic Blizzard of '78, as locals call it. Nonetheless, it was nothing to sneeze at and snow removal was an arduous process. Some great historic photographs capture police and other officials in contemporary vehicles trying to clear the roads. So much for the most romantic day of the year, unless staying inside trying to keep warm and keep the house lit is considered romance.
Neither the 1940 St. Valentine's Day Blizzard nor the more recent 2007 St. Valentine's Day Blizzard caused much damage or time lost to Boston. Nonetheless, February can bring a lot of snow, so couples should keep an eye on the weather reports as they make their plans for Valentine's Day.
