Surface Map: High pressure along the Mid-Atlantic coast will keep the region dry. A few showers will push through the Northeast. Tropical Storm Karen will begin to approach the Gulf Coast bringing tropical storm force winds and hurricane wind gusts to the region from MS to FL along the coast. Flooding rains and also storm surge will be a problem this weekend. Severe thunderstorms will be possible from Chicago to Houston along the cold front. Blizzard conditions will dominate the weather over Eastern Wyoming and Western South Dakota as low pressure moves through the region. The West Coast will enjoy high pressure and mild weather.
Severe Weather: The region along the frontal boundary will be the focus of severe weather with tornadoes, large hail, damaging winds, and heavy rainfall. A second area of severe weather will be possible along the Gulf Coast ahead of Tropical Storm Karen.
Winter Weather: Frost and Freeze warnings scattered throughout the West due to high pressure and the cooler air in place. A blizzard warning is in effect from Western South Dakota into Eastern Wyoming with some places seeing snowfall in excess of 12-18 inches. Winter storm watch is also in effect for regions around the blizzard. These places will see around 6-8 inches of snowfall.
