NEW YORK – All eyes are now on the development of a powerful winter storm that could be crippling along parts of the Eastern Seaboard. Washington D.C. is under a blizzard Watch as of Wednesday afternoon. The latest models are showing New York missing the full brunt of the storm, but still getting walloped by a good deal of snow and/or rain. Winter Storm Watches have already been issued for most of New Jersey as the storm will start sooner there. The rest of the region will eventually get a watch later Wednesday or Thursday.

A few changes have developed since Tuesday with regards to the timing of the storm. The storm, which The Weather Channel has dubbed Winter Storm Jonas, may not begin until Saturday morning after 6 a.m. Much of the snow will be generally light until sometime in the afternoon and evening when the area of low pressure will be passing south and east of the region. That will be when most of the accumulating snowfall will occur. Eventually the storm will taper off late Saturday night into Sunday morning and the sun will begin to peak out by the afternoon.

While it is still early, in terms of snow amounts, generally 6"-10” will be possible around the city. Central New Jersey, away from the shore may get the highest amounts as they could be approaching a foot or more. North of the city away from the coast may get a sharp cut-off resulting in lower amounts in a short distance -- around 6” or less as they will be farther away from the storm. Long Island, especially on the east end, and the Jersey Shore could get tricky as some mixing could occur which could lower amounts somewhat.

As previously mentioned, with the full moon taking place this weekend, high tides will naturally be higher than normal. Add in the storm's impact and there will be problems along the coast. Gusts as high as 50 mph could push water along the shoreline, bringing a storm surge of 2 – 3 ½ feet. That may bring moderate coastal flooding during the two high cycles of Saturday.
