Weather

Beast of the East

By Michael J. Ring
STAFF METEOROLOGIST

A rapidly intensifying cyclone will bring miserable weather to the eastern half of the country over the next few days.

As we move through air masses in different regions of the storm, our temperatures will vary between now and Thursday. Today, we are on the far northeastern edge of the cyclone. As the cyclone center moves closer to us, however, a warm front will pass over Boston. A warm front features warmer air rising and overtaking colder air, so after its passage temperatures will increase. Hence Wednesday’s high temperatures will be much warmer than those of today.

Trailing behind the storm center is a cold front. The cold front is identified by cold air sinking and replacing warmer air, which is forced upward. After the cold front’s passage on Wednesday night, temperatures will return to cooler values.

While temperatures will vary greatly over the next several days, the clouds and rain will be constants. Rainy weather will dominate the next few days from Maine to Missouri, while in the upper Midwest several inches of snow are expected.
