Northeast and Great Lakes Weather

Tuesday 8 a.m.

While it will be generally mild to warm, a frontal zone will cause changes as it moves southeastward today, stalls tomorrow in Maryland or Virginia, then moves back north on Thursday and Thursday night. Some showers and thunderstorms will affect the area from the Ohio Valley into the Northeast today (west) and tonight (east).

All the computer models show heavy rain during the Thursday to early Friday period in the area surrounding Lake Michigan. Racine, Wis., and Kalamazoo, Mich., have had close to average rainfall for all of April even though the month is barely half over.

The storm that brings rain farther south will cause more snow in the upper Great Lakes. It may get cold enough to allow snow showers in western Michigan by Friday night then in western New York by Saturday morning.

This video deals with Northeast weather for the rest of the week and into the weekend.
