Discussion
*A major winter storm will impact the Mid-Atlantic region on Wednesday with significant accumulating snow on the front end in many areas before a changeover to ice and rain.* An initial low pressure system will head towards the Great Lakes on Wednesday and a secondary low pressure will form near the Mid-Atlantic coastline. Another key player will be strong cold high pressure that will be situated to our north at the beginning of this mid-week event and it will lock-in cold, dense low-level air. Snow should break out by mid-to-late morning (7-10AM) in the Philly metro region and it'll become heavy at times. By later Wednesday, milder air will advance into the region as winds turn more to the southeast and this should result in a changeover from snow to sleet and freezing rain and likely to plain rain by later Wednesday night. Accumulations expected on the order of 3-6 inches before the changeover (higher amounts in that range to the west, lower amounts to the east). The low pressure areas moves away on Thursday and allows for high pressure to build in from the west.
