A sleet/snow mix arrived in Maryland Wednesday morning. It quickly changed to rain from Annapolis south, and for most of the Eastern Shore. In Baltimore City, there was about 1″ accumulation before changing to rain around noon. And the changeover took longer for Baltimore, Carroll, Harford, and Frederick County, after leaving about 1-3″ accumulation. As of this writing (4:30 p.m.), temperatures are still below freezing from Hagerstown west, so anything coming down will be sleet or snow.
From the city southeast Wednesday night, temperatures will be close to or above freezing. That will keep main roads wet, but watch for overpasses, exit/entrance ramps and bridges that may freeze overnight. North and west of the city, watch for the slush to re-freeze and untreated roads for some possible ice.
The heavy bands of rain will wind down overnight. A few rain showers maybe even mixing with snow showers will linger into Thursday morning before this storm finally leaves us. However, a wind advisory goes into effect Thursday for wind gusts over 40 mph. It will very windy, but a drier wind that allows some sunshine to return.
Friday is looking chilly and calmer. The winds will back off and sunshine will be around. that is, before a new storm moves our way again Saturday. The rain/snow/mix zone will set up over Maryland once again. We will have more specific details on this storm, but it looks like there will be more cold air available for this storm. Then, cold air and the active storm track will hang around as we move into 2013 next week.
