The 12 cities that face the WORST of this weekend’s ‘bomb’ cyclone

Twelve cities across the United States face devastating winter conditions as a massive bomb cyclone threatens to terrorize the country – just days before Christmas and in the thick of holiday travel.

It is due to develop over the northwestern states and move east across the country, tearing through the great lakes, crashing into the south, and freezing the northeast with the coldest December temperatures the region has seen in decades.

Up to 18 inches of snow could fall in some areas, along with strong winds up to 55 mph. Even in regions where as little as 4 inches of snow fall, the wintry mix is ​​expected to bring critically dangerous conditions.

The storm is expected to begin Wednesday, strengthen through Thursday, and continue its reign of chaos through the night and across Friday. In the vicious conditions – where wind chills could reach minus 40 – frostbite could take hold in just 10 minutes.

The Iowa city faces a storm warning beginning Wednesday evening and holding until Saturday morning.

Snowfall is due to begin at the end of the day Wednesday and continue through Thursday, before developing into a blizzard Friday. Between three and six inches of snow are expected to fall within the city itself, with more accumulating north of town.

WHAT IS A BOMB CYCLONE?

A bomb cyclone is a large midlatitude storm that intensifies quickly, bringing heavy snow, rain, high winds and coastal flooding.

Midlatitude is a temperate zone north of the tropics that includes the entire continental US.

The name comes from the meteorological term ‘bombogenesis,’ or ‘explosive cyclogenesis,’ when a storm system’s central pressure drops at least 24 millibars within 24 hours.

A study found in 69 percent of cases, bomb cyclones frequently happened from December to February and early March.

The US Eastern Seaboard is one of the regions where bombogenesis is most common because storms in the midlatitudes draw their energy from large temperature contrasts.
