Howard and Carroll counties -- and much of the region -- could be in for another dose of winter weather this weekend, depending on how an approaching storm shapes up.

The National Weather Service warns that a system moving in from the southeast "will likely impact portions of the Mid-Atlantic Saturday and Saturday night."

"At this stage, rain or snow is possible depending on the storm track," it adds.

The latest forecast for the area calls for a mix of rain and snow starting Saturday morning, then switching over to just rain by early afternoon.

Snow may slip back into the picture Saturday evening as temperatures drop again.

Though the NWS expects minimal accumulation over the course of the day, AccuWeather puts potential snowfall totals for the Baltimore-Washington corridor in the 1-3 inch range.

Patch will have more information on this storm as it becomes available.
