The latest models maintain an off-shore track of the storm Wednesday night into Thursday. A slight westward trend that existed a few days ago has become almost imperceptible.
With the track of the storm remaining mostly unchanged, the difference in the forecast depends on the size of the precipitation shield around the storm with the some models having a large enough shield of precipitation to affect south Jersey and somewhat reaching PHL and its immediate suburbs. Other models, notably the NAM, have kept the precipitation shunted to our east.
The new experimental National Blend of Models maintains a 52% chance of snow with an accumulation of about 1.5 inches in PHL, more south and east in NJ. Some of the other new statistical models also show a near 50% chance with overall amounts in the 1-2 inch range.
So right now, a minor storm for PHL, somewhat greater for Atlantic City and Cape May and northern New England. Things have a way of changing, but right now, the actual track, off-shore, is unusually consistent and doesn’t show the variability of past coastal storms. Stay tuned.
