Wintery Mix On The Way

Another combination of low pressure systems is poised to move to the Mid Atlantic region in the next 24-48 hours, this time with a slightly different flavor.

The enhanced midday satellite image shows high pressure with cold air over the northeast U.S. Low pressure centers in the Gulf and the Plaines are forecast to move in the directions of the arrows in the next 24 hours.

Unlike previous storms this season, warmer air will move in as the storms advance and what may start out as snow will transition to sleet, freezing rain and eventually rain. The precipitation is expected to start in the late afternoon or early evening on Monday and progress from there.

The Tuesday morning rush hour may be impacted by icy conditions over parts of the area as indicated above by one of several computer models. The storm is expected to move away from the area on Wednesday, pulling in cold air behind it. Another storm, possibly coastal, may move into this colder air by the end of the week. Computer models are not totally in agreement on storm tracks with this feature as of now but the National Weather Service forecast map for Friday places a storm center off the northeast coast.

It appears the end of week system might be somewhat progressive and that would limit the amount of snow that it would drop on the area.

It looks like an interesting week of weather coming up so check back with wbaltv.com for updates and tune in Tom, Tony and Sandra for the latest on TV-11.
