JACKSON, Mississippi — Confidence is rising that a significant severe weather outbreak will develop across the Mid and Deep South on Wednesday, May 6. Mississippi, Tennessee and Alabama sit directly in the highest-risk corridor as two jet stream energy sources phase together and amplify the threat. Surface moisture near 71 degrees Fahrenheit across Jackson confirms the atmospheric ingredients for a dangerous storm day are already locking in.
Why Wednesday’s Setup Is Being Taken Seriously
Two separate upper-level jet streams are forecast to phase, meaning they will merge and concentrate their combined energy into a single, more powerful system. When jets phase, upper-level wind speeds surge and storm support below increases dramatically.
The highest-energy overlap zone currently targets a corridor covering Memphis, Tennessee, Jackson, Mississippi and Nashville, Tennessee. Both independent probability forecast systems now agree a severe weather event occurs Wednesday, with the maximum severe storm probability reaching 26.7 percent at five days out. That level…..
