An elevated area for severe weather is forecast to across central Florida on Monday. The low is forecast to track to the east near North Carolina by Monday evening. The National Weather Service has issued winter storm warnings and advisories from northern Arkansas/southern Missouri to western North Carolina and southern New Jersey. Only a dusting or flurries are forecast for the New York City metropolitan area on Monday. Washington, D.C. is expecting 3 to 6 inches of snow with up to 4 inches for Atlantic City.

A storm system that spread rain this weekend to Washington will move eastward spreading heavy mountain snows across the northern Rockies into tonight. This system will intensify into a storm that will track across the northern plains to the Great Lakes by Wednesday and into eastern Canada by Thursday. Snow and strong winds can be expected Tuesday and Wednesday from the northern Rockies to the Great Lakes.
It is interesting to note that there was a wide difference in the NAM model runs and the GFS model runs during the last two model cycles. The NAM was producing a strong, compact low pressure system moving along the East Coast spreading heavy rain and strong winds into New York City and southern New England by Wednesday. However, the latest 12 Z NAM is now more in line with the GFS and keeps this system well south of New York and moving away from the coast.
