BOMBOGENESIS (a rapidly intensifying storm) will take place Tuesday afternoon off the Virginia coast.
Computer models had an extreme reversal on the intensity and track of this storm over the last 24-36 hours, and that’s why snow amounts were jacked up Monday as computer models came late to the snow party.
Hinting started to take place late Sunday as my forecast called for a significant storm for some with 4+ inches of snow possible across parts of New Jersey. But a big uptick in moisture being fed into the storm combined with a piece of the polar vortex sending another package of severe cold. This time, it gets pulled into the storm’s circulation leading to rapid intensification and high snow ratios.
Normally we receive a 10-1 ratio, with one inch of liquid equaling 10 inches of snow, but in this case we have an overall ratio of 13-1, to as much as 15-1, meaning more snow with less liquid.

People in Western Pennsylvania braced Wednesday night for a second round of potentially devastating storms following torrents that dropped as much as 3 inches of rain in some parts of the area during the day.
But all of the foreboding and warnings ended up as mostly just that as a string of storms that arrived shortly after the evening rush hour brought with them less rain than was expected.
“It moved through so quickly,” said meteorologist Brad Rehak, of the National Weather Service. “It wasn’t as heavy.”
Rainfall that was expected to end just after midnight should be replaced throughout the next three days with drier, more comfortable weather — aiding in crews’ cleanup efforts.

Met-Ed and PPLelectric utilities have to improve their tree-trimming and line maintenance so that preventable outages like those that occurred during the major storms of 2011 can be reduced or eliminated.
The utilities also must be more responsive to customers during major storms, according to three reports critical of the utilities, issued this week by the state Public Utility Commission.
The reports were ordered in the aftermath of Hurricane Irene last August, flooding rains from the remnants of Tropical Storm Lee in early September, and the freak late October snowstorm.
“Tree trimming should be a primary concern for both the (electric utilities) and commission for its effect on reliability as well as its role in long-duration outages,” the report said.
Due to the anticipated impact of Hurricane Irene, King of Prussia Mall will be closing at 5 p.m. as a precautionary measure to help ensure the safety of shoppers, retailers and mall employees. The mall expects to re-open tomorrow at 11 a.m. for regular business hours. Should that change, more information will be posted as soon as it becomes available.
