This Storm Will Likely Undergo Bombogenesis
An area of low pressure will explosively intensify near the New England coast Sunday night into Monday.
In fact, Winter Storm Orson is expected to undergo bombogenesis during the Sunday night into the Monday evening time period.
In order to meet the criteria of "bombing out," the central pressure of a low-pressure system must drop at least 24 millibars within 24 hours. This typically happens when there is a large temperature gradient, usually between a cold continental air mass and warm sea-surface temperatures.
Storms that reach this threshold are accompanied by very heavy precipitation and strong winds, which is what is currently anticipated with Orson. Thundersnow and blizzard conditions can occur.
