The National Weather Service in Mount Holly has issued a Winter Storm Warning for snow...which is in effect from midnight tonight to 4 PM EST Thursday. The Winter Storm Watch is no longer in effect.
* ACCUMULATIONS...Snow accumulation of 6 to 10 inches.
* LOCATIONS...Eastern Pennsylvania and central and northern New
Jersey.
* HAZARD TYPES...Heavy snow.
* VISIBILITIES...One quarter mile or less at times..
* TIMING...A wintry mix will overspread the area from the west

The event will likely begin as snow north of the I-78 corridor.
Elsewhere, rain will change over to snow from northwest to
southeast into early Thursday morning. Sleet may mix in briefly
during the transition from rain to snow. The snow likely will
be heavy for a time Thursday morning before tapering off
quickly from west to east during midday or the afternoon.
* IMPACTS...The heavy snow will make many roads potentially
impassable for several hours during the worst part of the storm
which should be 5 am to 10 am. There may be widespread power
outages due to the weight of the snow on tree limbs and power
lines. The threat for power outages will be less where
temperatures are mostly below 30 degrees during the snow.

* TEMPERATURES...falling into the 20s over most of this area
