Tomorrow is the first day of spring but we will be watching a snow event unfold
The disturbance over the southeast will slowly move east northeast and redevelop off the Delmarva coast, how quickly it intensifies will determine how much snow we get and thus this is Avery high volatility forecast, if it is slow to get its act together it will track farther south leading to less dynamics to overcome the March sun and thus less accumulation , if it gets its act together quickly heavy precipitation will likely be able to hinder the effects of the early spring sun angle
Snow will overspread the area from southwest to northeast between 7 am and 12 PM , lasting through the evening hours, it will change to rain along coastal areas before clearing out Friday night
This is the current snowfall forecast, I marked the central NJ and Philly area as high volatility because that’s where the heaviest precipitation is likely to fall and be borderline between rain and snow , right now I’m sticking with climatology in this area but if the heavier precipitation is able to cool the column then amounts would likely have to be raised quite a bit in these areas, I feel pretty comfortable with the rest of the area for now. I’ll have n updated map if needed tonight.
Most of these accumulations will be confined on grassy surfaces but tomorrow evening could start to see accumulations on the pavement especially if heavier snow is falling
