Day 4-5...Models Have Converged On Amplitude And Timing Of A Strong Progressive Shortwave Trough That Will Move Through The Srn Plains Day 4 /Wednesday/...Lower Ms Valley Wednesday Night And Into The Oh Valley And Sern States Day 5 /Thursday/.
This System Will Induce A Strong Surface Low That Will Move From Ks/Ok Wednesday Into The Oh Valley Thursday. A Cold Front Will Sweep Ewd Through The Lower Ms Valley And Sern States In Association With This Feature.
Partially Modified Gulf Air Will Advect Nwd Along A Strong Llj Resulting In Destabilization. However...Instability Will Likely Remain Marginal
Due To Expected Weak Lapse Rates.
Despite The Limited Instability...Expect A Line Of Forced Convection To Develop Wednesday Night Over The Lower Ms Valley And Continue Ewd Through The Tn Valley And Sern States Day 5 /Thursday/.
Given The Strength Of Near-Sfc And Deep-Layer Flow...Damaging Wind May Be A Threat As The Activity Develops Ewd.
