Our models since last week have been hinting at the potential for a coastal storm to develop some time Tuesday night into the day on Wednesday. Our forecast models have come into agreement that a few inches of snow is likely with other models indicating close to a foot could fall in parts of Maryland.
Here is a look at the storm system Sunday night. As it moves south and east it will gather strength interacting with warm air over the southern states and cold Canadian air to the North. By Tuesday it will bring snows to Chicago, Indianapolis, Dayton, and Cleveland before redeveloping a coastal low for Wednesday.
