Back To Winter

A new storm system is developing and it will provide a wintry mix for the area over the next 24 hours.

The morning satellite image shows the storm stretching from the Midwest to the Northeast states.

The morning surface weather map details what is going on under those clouds. A front is draped across Maryland and on to the west. At 10:00am, temperatures in southern Maryland are about 10-20 degrees warmer than in the Baltimore area. Although the map shows the front to be a warm frontal boundary, the reality is that the front won’t be moving all that much during the day and will push south later in the day and overnight.

The low pressure center over Garrett County will move east today and a second low in the Midwest will take a more southerly track into Virginia tonight, allowing colder air and more snow to move farther south than anticipated over the weekend. This means a little more snow accumulation than originally thought for the Baltimore metro area by the Tuesday morning rush hour.

A computer model used in the WBAL weather office forecasts an accumulation of 2-6 inches of snow from the Annapolis/Washington area northward into southern Pennsylvania with the heaviest accumulations just north of Baltimore, indicated by the darker blue/purple shading.

 

A Winter Storm Watch Warning has been issued for the northern tier of counties in Maryland northward into Pennsylvania and a Winter Weather Advisory is in effect from Southern Baltimore County and Baltimore City southwestward to Washington, DC. A Winter Storm Watch is in effect for southern Pennsylvania.

All of this is subject to some fine tuning so check back with wbaltv.com from time-to-time and watch Tom, Tony and Sandra for the latest on WBAL-TV 11
