The SPC has upgraded western MS to a moderate risk for Friday driven by the threat for several tornadoes, some of which could be strong. All of the parameters look to be coming together for a classic spring severe event. Storm mode looks to initially favor discrete supercells capable of all weather modes starting Friday afternoon over parts of LA and AR. These storms will advance east into western MS late evening into the overnight hours eventually forming into a broken line of bowing segments. Even after this transition, tornadoes will still be possible. Exact timing of these storms and their evolution from discrete to more linear are still up in the air, it if you live in or near the moderate risk area be prepared for severe weather starting late afternoon.
