Weather

Enjoy the Snow

By Roberto Rondanelli
STAFF METEOROLOGIST

The most significant element of today’s forecast is the low pressure (996 mb) over the Atlantic. This low has traveled from the South bringing solid precipitation over sections of the East Coast, approaching New England last night. The center of the low will be located several hundred kilometers off the coast of New England.

There is significant uncertainty about the total amount of snow that this storm will bring, especially due to the large gradient in precipitation between the cape and the interior areas of Massachusetts (that is, slight changes in the trajectory of the low can produce significant changes in the total amount of snow). However, most of the models agree that the precipitation will be heavier over the Cape and Islands than in Boston. For Boston, we can expect from 2 to 4 inches of snow by the end of the storm.

After the passage of the storm, a high pressure will dominate the weather over the next few days, bringing dry and chilly conditions over most of the Eastern U.S. Unseasonably cold temperatures are expected for Wednesday and Thursday morning.
