Severe Thunderstorms to Threaten Southern States
A storm system forecast to help sweep colder air from the Rockies and northern Plains to the East starting this weekend will trigger strong to locally violent thunderstorms in the southern states.
Soon after snow falls over Wyoming and Colorado, the clash of the cold air charging into warm, moist air will unleash a few big thunderstorms late Friday into Friday evening from north-central Texas to eastern Kansas.
A few of the strongest storms can bring large hail, damaging wind gusts and blinding downpours. While this is not expected to be a major tornado-producer, there is the risk of a few tornadoes being spawned from the strongest storms.
While the storms will weaken during the overnight hours Friday into Saturday morning, they are expected to re-fire farther to the east from the upper Texas Coast to eastern Tennessee Saturday afternoon.
The storms will bring the same risks as that of the southern Plains, except more of the storms could be severe, as they are closer to the source of warm, moist air, the Gulf of Mexico.
The storm threat will reach from the central Gulf Coast and central Tennessee Valley Saturday night.
The conditions for severe weather may diminish by Sunday over the southern Atlantic Seaboard.

The "Dead of Winter," the one-month period when normal temperatures reach their lowest levels, has come to an end for much of the United States. Some people may find it odd that the "Dead of Winter" does not encompass the darkest day of the year (the first day of winter). That is due to a seasonal lag in temperatures. More heat continues to be lost than is gained from the start of winter until this time of year.
