The National Weather Service has upgraded the Winter Storm Warning for western New Jersey to a Blizzard warning. As impressive as that sounds (and it is) the only real difference between the two is the amount of sustained wind you receive. Technically a blizzard has 3 consecutive hours of steady 35 mph winds, reduced visibility due to falling AND blowing snow.

Most of the computer model this morning has suggested the storm will be more intense. This has lead to the NWS to increase their prediction to 18-24.” At this point I’m going to do the same. We can and do get that much snow from strong storms in western New Jersey so this may be added to the list.

...Blizzard Warning in effect from 8 PM this evening to 6 PM EDT Tuesday...

The National Weather Service in Mount Holly has issued a Blizzard Warning, which is in effect from 8 PM this evening to 6 PM EDT
Tuesday. The Winter Storm Warning is no longer in effect.

* Locations...eastern Pennsylvania and much of northern New   Jersey.

* Hazard types...heavy snow and strong winds.

* Accumulations...snow accumulation of 18 to 24 inches. 

* Timing...snow begins between 10 PM and midnight from southwest   to northeast across the warning area, becoming heavy at times 
  with snowfall rates of three to four inches per hour for   several hours Tuesday morning. Snow will diminish late in the 
  day Tuesday.

* Impacts...the heavy snow will make many roads impassable and   may produce widespread power outages due to the weight of the 
  snow on tree limbs and power lines. Strong winds will lead to   blowing snow, reduced visibility, and additional power 
  outages. 

* Winds...northeast 15 to 25 mph with gusts up to 40 mph.

* Visibilities...less than one-quarter mile for several hours. 

* Temperatures...in the mid 20s.

Precautionary/preparedness actions...

A Blizzard Warning means severe winter weather conditions are expected or occurring. Falling and blowing snow with strong winds
and poor visibilities are likely. This will lead to whiteout conditions...making travel extremely dangerous. Do not travel. If
you must travel...have a winter survival kit with you. If you get stranded...stay with your vehicle.
