The areas most likely to experience this activity include: northwest Alabama western and central Kentucky northern Mississippi western and middle Tennessee Elsewhere, severe storms are also possible from the Ohio Valley to central Gulf Coast. A late-winter storm system over the central U.S. this morning will undergo significant intensification today while advancing eastward into the Mississippi Valley. A line of severe thunderstorms is expected to develop by late afternoon over parts of the middle and lower Mississippi Valley as a strong surface cold front encounters a seasonably warm and moist air mass streaming north from the Gulf of Mexico. Powerful jet stream winds of over 100 mph in the upper atmosphere will interact with the developing thunderstorms to promote a fast-moving squall line which will impact much of the Ohio and Tennessee Valleys as well as the lower Mississippi Valley into central Gulf States this evening into overnight. Corridors of substantial wind damage appear likely along the squall line track...along with a few tornadoes. State and local emergency managers are monitoring this developing situation. Those in the threatened area are urged to review severe weather safety rules and to listen to radio, television, and NOAA Weather Radio for possible watches, warnings, and statements later today.
