A potentially ballistic severe weather setup is in place along the Mississippi River today, just a little father north than it was a week ago when Yazoo City, Miss., was demolished. The bullseye based on current (4:30 p.m. EDT) parameters appears to be southeast and east-central Arkansas — CAPE of up to 3500, deep layer shear 50 to 70 knots, low-level shear 25 to 35 knots and the significant tornado parameter as high as 5. Overnight heavy rain and storms has left plenty of boundaries for new storms to fire along and ingest.
Some of this area is flat, cleared agricultural terrain and would be chaseable, though river crossings, especially over the Mississippi, can make following storms tricky.
As usual, add any comments or observations you may have about today’s severe weather situation. I will be watching very closely with personal interest, having grown up in northeast Arkansas, where my mother still lives.
