Widespread damaging winds and several tornadoes are forecast on Monday for parts of the Mid Atlantic and Southeast. ...Discussion... A large and deepening upper trough will eject east/northeastward out of the MS/OH/TN Valleys and across the Appalachians and into the Mid Atlantic/Northeast on Monday, with an expansive area of strong wind fields aloft. A surface low move from Lower MI into southern Quebec, with a deep pre-frontal trough extending southward across eastern PA, VA, and NC by around 21Z. Ahead of this trough/front, southerly winds will bring 60s F dewpoints as far north as southeast PA. Storms will likely be ongoing along the length of the cold front, roughly from OH to the FL Panhandle Monday morning. Given the uncapped air mass over the Carolinas, a few storms, possibly supercells, may develop relatively early in the day as well, with tornado potential. The greatest threat however will be during the afternoon as cold front nears, and pressure falls are maximized along with daytime heating. A few supercells ahead of the line will be possible, along with embedded circulations and/significant damaging winds within the squall line. There are model differences regarding the speed/position of the cold front, as well as the degree of instability. Regardless, damaging winds over a large area appear likely, along with at least a few tornadoes. Depending on the degree of destabilization, a strong tornado or two may occur especially over parts of the Carolinas and Virginia during the late afternoon. Many models forecast 300-500 m2/s2 SRH, along with pockets of SBCAPE over 1000 J/kg, which is clearly favorable for tornadic supercells. ..Jewell.. 03/14/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
