Some Light Snow for DE and SJ during Thursday PM. Weekend Storm Cancel ! Updated 8:00 PM Friday.

Friday 12/17/10
8:00 PM Update

It looks like our weekend storm will track much further east and offshore on Sunday. Some flurries or a period of light snow is possible over Southern/Central DE and Eastern parts of Southern/Central NJ towards the coast.

This will occur during Later Saturday night into Sunday. A Coating to 1" is possible along the coastal sections. If anything changes and the track should shift further west, some changes to this call will be made by tomorrow afternoon. All indications are favoring an offshore track, so this greatly decreases our chances for any significant snowfall.

From Wilmington DE, to PHL PA, to Trenton NJ, and points North and West, only M.Cloudy skies can be expected on Sunday.
Discussion and Forecast
Issued: Wednesday 5:00 PM

A low pressure system now developing over Eastern Tx will move ENE to the Tennessee Valley Thursday morning, then East to the VA coast by Thursday evening.

For our Mid-Atlantic friends in Southern and Central VA, snow will accumulate 3"-5" before a changeover to IP and ZR before ending. ROA/LYH and RIC are game once again. Snow starts later tonight and continues for much of the day on Thursday. All snow and mixed precip should end by early Thursday evening.

Most of DE and Southern NJ will see a period of Light snow Thursday afternoon into the early evening hours.

From ILG, DE to ACY, NJ and all points south of this line, A Coating to 1" of snow accumulation is possible later Thursday afternoon and evening.

From DOV, DE to Sea Isle, NJ and points south: This includes all of Central/Southern DE and Cape May CO, NJ will see a general 1" to perhaps isolated amounts of 2" of snow accumulation.

For PHL and points North, just expect a brief period of light snow and flurries for tomorrow afternoon and evening ! Little or no accumulations for these areas.

On Friday, I'll have more on the weekend storm with a more solid call, but at this time it looks like DE and much of NJ will be in the best spots for accumulating snow, from Saturday night into Sunday evening. My preliminary estimates are for possibly a general 2"-4" of snow accumulation.

For points North and West of PHL, lesser amounts are likely, as this will be a coastal storm and will track far enough offshore to bring heavier amounts of snow, mainly east of PHL. It still appears that PHL and Eastern PA, will still have a shot at some accumulating snow with this storm. Stay tuned for Friday update as this is a tricky storm to forecast and things are subject to change by Friday's call.

I'll likely do an Audio/Video presentation, and provide a snowfall map if needed with this weekend's storm threat.
