Orange County is expected to miss most of the snow promised by the "bomb cyclone," a term meteorologists have been bandying about lately to describe the extreme weather we've been having. But brutal temperatures will more than make up for the lack of snow: highs in the single digits and winds up to 21 mph are expected Friday and Saturday.

The National Oceanic and Atmospheric Administration has a Wind Chill Watch in effect from Thursday evening through Saturday afternoon in Orange County. Dangerously cold wind chills as low as 30 below zero will cause frostbite in as little as 10 minutes to exposed skin, especially Friday night into Saturday, according to the NOAA. Also beware that the very cold air might freeze exposed plumbing, if preventive measures are not taken.

So what exactly is a "bomb cyclone"? Also called bombogenesis, it's basically a winter hurricane marked by quick drops in atmospheric pressure. The NOAA says this can happen when a cold air mass collides with a warm air mass, such as cold air over warm ocean waters. The cyclone thus created rapidly intensifies, strengthening the storm.

Snow is expected along the coastline, including areas east of the Hudson River, which will get six inches or more, according to forecasts.
