Weather: Digging for Spring
By Robert Lindsay Korty
The 27.5 inches (70 cm) of snow that fell at Logan airport on Monday set a new record for Boston, though most locations around the city and its suburbs received at least 7 inches (18 cm) less than Logan did. Pedants may quibble about whether the storm was technically a blizzard; it hardly matters. The snowfall alone made this an impressive storm. Perhaps more noteworthy is that this storm was rather mundane by many objective measures of strength: the pressure was not particularly low, the upper level signature was rather standard, and the surface wind field was blase. The combination of an Arctic high pressure to our north (it was 0°F (-18°C) two nights last week in Boston), copious moisture, and the storm’s slow movement produced the large volume of snow that fell across the Northeast.
This weekend a new, potent storm will move to the East Coast. With the loss of the Arctic high, warm air in advance of the storm will cause most of the precipitation to fall as rain in Boston. With the large snowpack from Monday and the heavy rain this weekend, there may be some flooding. That sounds like spring, but the potential for snow returns on Monday.
