A major east coast storm will greatly impact the DC metro region from this evening into tomorrow night with the biggest snow accumulations of the year in many areas. This storm has already caused major problems in the Deep South in terms of ice and snow and a widespread swath of heavy snow is likely over the next 48 hours from the higher elevation mountains of the Carolinas to northern New England and significant icing is possible just to the south and east of this heavy snow accumulation band.
Strong low pressure will move to around Norfolk, VA by later tonight on its way to just off the New Jersey coastline by tomorrow evening and then to near Cape Cod, MA by early Friday. Snow should begin later this evening around here and continue into Thursday and then mixing with or changing to sleet and/or freezing rain for awhile; especially, from I-95 to points south and east. If a changeover to mixed precipitation does indeed occur, then it’ll likely change back to “wrap-around” snow later tomorrow as we enter the “cold conveyor belt” region of the storm on its northwest flank. There is also the possibility for some “thunder snow” to occur during this upcoming event and expect varying precipitation intensities on Thursday. The snow will linger into tomorrow night potentially forcing driving problems to continue into early Friday. Current snowfall estimates are in the 8-14 inch range with the higher amounts in that range occurring in the northern and western suburbs and the lesser amounts to the south and east.
