Discussion
Low pressure will develop along the Carolina coastline tonight and then intensify rapidly as it rides right along the Mid-Atlantic coastline on Wednesday. Precipitation will break out later today or early tonight; primarily, in the form of rain, but as colder air gets wrapped into the system and “dynamical cooling” develops, the rain will change to snow in the overnight hours and snow should be the predominate precipitation type on Wednesday in suburban locations, but mixing will likely continue in Philly and points south and east. There can be intense bands of snow on Wednesday with a couple inches per hour possible and thunder snow is also on the table during this event. The heaviest snowfall accumulations are likely to be in the N and W suburbs where 4-8 inches is on the table with locally higher amounts and 2-4 inches is likely in Philly. Any shift in the expected storm track would have an impact on the axis of heaviest snow. Stay tuned.
