June 12, 2013; 10:25 AM ET


The storm will be a multi-billion dollar storm and will cause power outages and significant damage the next two days.

A severe weather outbreak will start today in the Midwest then move into the mid-Atlantic Thursday.

In the Midwest, storms will develop late this afternoon across northern Illinois where a tornado threat will occur. Eventually the storms will translate into a damaging wind event across Indiana into Ohio. Significant damage may occur between the tornadoes and wind damage.

Heavy rains will hit Wisconsin into Michigan later today and tonight. Flash flooding may occur across southern Michigan.

Thursday, the severe weather will hit areas from southern Pennsylvania into Virginia, North Carolina, New Jersey, Maryland and Delaware. That area could see significant tornadoes and wind damage in the afternoon. Simulated radars suggest after 2 p.m. the storms develop and start as supercells and quickly become a squall line with damaging wind gusts.

Flash flooding rains will occur across northern Pennsylvania, New York into New England Thursday into Thursday night. That area could get 1-5 inches of rain.

Coastal winds will develop Thursday night and hit the Jersey Shore, New York City, Long Island into southern New England. Winds in that area will gust 35-50 mph.
