SURPRISE! A snowstorm!
A low pressure system is currently developing off the coast of South Caroalina. The storm should track northeast tonight into tomorrow passing just south of the 40/70 benchmark.
So what does this mean for us?
A rain/snow mix should start to move into New York City, Long Island and Fairfield county in the next few hours. By around 4 AM the precipitation should become much more widespread with snow and sleet falling everywhere except for Orange county where precipitation won't move in until around 6 AM. Snow should last into the morning and won't start to taper off in western counties until around 9 AM. By noon the snow should move out of New York City. The snow will last longest on Long Island where the snow will last until mid afternoon.
The heaviest accumulations will be on Suffolk county where as much as eight inches is possible. I expect about 4 inches in New York City. I'm not too confident with the snow on Long Island as there will be mixing issues.
The combination of a tight baroclinic zone and a nearby rain/snow line could cause a heavy snow band to form in the areas circled in purple. I'll have an update in the morning if this does end up being the case.
Travel will be very difficult for almost everyone in the coverage area tomorrow morning. Expect closing and delays for school/work to expand.
