A powerful winter storm forming in the central part of the country will quickly become a bomb cyclone as it moves east, bringing damaging winds, heavy rain and even snow
from Louisiana to Maine, according to CNN.
A bomb cyclone occurs when the pressure of a mid-latitude cyclone decreases by 24 millibars in less than 24 hours, according to the National Oceanic and Atmospheric Administration (NOAA). These strong systems create many hazards, but the most notable may be extreme winds.
A combination of extremely high winds and snowfall promises to wreak havoc on northeast as the bomb cyclone reaches hurricane strength off the Atlantic coast.
The National Weather Service (NWS) forecast temperatures to be well below normal across the US. from Wednesday to Saturday. With early greening in some places, this sudden cold snap could have a significant agricultural impact.
Much below normal temperatures are expected to push across the US Wednesday through Saturday. With early green-up across some locations, this abrupt cold snap could result in significant agricultural impacts.

This storm will start with a powerful blast of cold air from southern Canada towards the plains and the Rocky Mountains. This cold blast could set several daily record lows in parts of the western and plains United States, according to weather.com.
“All Guidance models have surface waves (the storm) that rapidly intensify as it moves somewhere between corridor I-80 to Cape Cod, then along or just off the coast of Maine at least less than 970 mb,” the National Weather Service in Boston said.
A minimum of 970 millibars (mb) would be equivalent to a category 2 hurricane.

Snow Forecast
Heavy snow is forecast for parts of the Central and Southern Rocky Mountains and the Central Plains on Wednesday. Snow will cover the Rocky Mountains and parts of the Plains and the Midwest through Thursday.
The National Weather Service has issued winter weather watches for many of these areas, including a winter storm warning for the Kansas City metropolitan area and a winter weather advisory for Denver. A fairly wide area from the Rocky Mountains to Kansas could accumulate at least 6 inches of snow through Thursday.
As cooler air enter storm Friday night, rain may turn to snow in portions of valleys from Ohio and Tennessee to northern Mississippi, northern Alabama, and northern Georgia.
The heaviest snow from this storm is expected in the interior Northeast this weekend,
from the central Appalachians to northern Pennsylvania, the central and upstate New York and New England, where 6 inches of snow is possible.
Strong winds
There may be strong winds Saturday through early Sunday in portions of the east,
possibly as far south as the coastal Carolinas, extending to New England.
This threat is greatest along the coast immediately ahead on Saturday, as well as over higher ground in the Northeast. At least some fallen tree limbs and power outages are possible in these areas.
