The National Weather Service in Birmingham predicts severe storms by the end of the week. The latest forecast is as follows: "Severe weather, including the threat of damaging straight-line winds and isolated tornadoes, is possible late Thursday night through Friday morning. A line of thunderstorms is expected to move into West Alabama around 2 AM Friday morning and exit East Alabama by noon Friday. The approximate arrival times for the storms are listed on the image. The greatest threat for severe weather is expected mainly west of Interstate 65."

ABC 33/40 Chief Meteorologist James Spann outlines the threat on the ABC 33/40 Weather Blog: "The line of severe storms should enter Northwest Alabama around 2:00 a.m. Friday. Thankfully, instability values are marginal, but wind fields are pretty strong, and there is a decent amount of bulk shear in the lower 5,000 feet as well. The primary risk along the line will come from strong straight line winds, but an isolated tornado can’t be ruled out."

"The storms should weaken as they move east, and we believe the greatest risk of severe weather along the storm line will be north and west of a line from Tuscaloosa to Smith Lake to Huntsville from 2:00 a.m. until 5:00 a.m. Friday."

"The weakening band of storms should reach the Birmingham metro around 5:00-6:00 a.m… and then over into the Anniston/Gadsden area by 7:00-8:00 a.m. The risk of severe weather along the squall line is quite low to the south and east of Birmingham as the storms continue to weaken."
