Major, snowy changes to AccuWeather forecast

December 25, 2010 RELATED: Stormtracker 6, extended forecast and more on the Weather Channel

Over the last 12 hours the storm track has drastically shifted westward toward the eastern seaboard meaning we are going to see a significant snowfall across our region.

Currently the storm is centered well to our south down by the Georgia/Florida border and in classic nor'easter fashion will slowly move northeastward up the coast after receiving an injection of upper level energy that will cause it to rapdily develop and "bomb out".

The timeline for this event begins on Sunday morning where light snow will begin to break out across southern portions of the viewing area. By late morning and near midday the initial snow will be reaching the Philadelphia area and it will take until early afternoon for the Lehigh Valley beginning to see snow. As we go through the afternoon and throughout the evening we will see moderate to heavy snow for a good 12 to 18 hour period with snow ending before dawn on Monday.

Due to the potential for heavy snow the National Weather Service in Mount Holly has issued a Winter Storm Watch for Sunday morning through Monday afternoon for almost the entire viewing area.

Here is a look at what we are currently thinking for snowfall totals. Keep in mind if the storm track's even closer to our area these numbers may need to be ajusted up.

For the far western suburbs including Allentown, Reading & Lancaster we are looking for 4" to 8".

For the I-95 corridor and immediate southeastern Pennsylvania and western New Jersey we are looking for 5" to 10". This includes Philadelphia, Trenton, Wilmington, Pottstown, Doylestown, West Chester, Camden, and Mount Holly.

For central Delaware and the eastern half of New Jersey and right along the coast we are looking for 7" to 14". This includes Dover, Millville, Hammonton, Toms River, Atlantic City, Wildwood & Cape May.

Not only will this storm bring heavy snow, but gusty winds meaning reduced visbilities and dangerous travel conditions.

Anyone planning to travel later in the day on Sunday may want to try to leave earlier to avoid the brunt of the storm.

Tonight at 11pm Adam Joseph will have the very latest on the track of this nor'easter and any adjustments to snowfall totals.
