Bolaris: Old Man Winter To Drop Bombogenesis

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.
