Thunderstorms are possible from the lower Ohio Valley southwest into northeast/central Texas early on Wednesday and across the Southeast, Carolinas, and Florida Wednesday afternoon and evening. ....Synopsis... An upper trough will migrate across the eastern half of the CONUS on Wednesday. Boundary-layer moisture will remain modest across the southeast U.S., ahead of a southeast-advancing cold front extending from southern OH southwest to western TN and then central TX Wednesday morning. Isolated showers and thunderstorms are likely to be ongoing along the front at the beginning of the period. This activity will likely be elevated and just to the cool side of the surface front. Instability is expected to be very weak with southeast extent into the TN and Lower MS Valley, and morning thunderstorms will likely diminish in coverage as the front moves southeast. Severe thunderstorms are unlikely given limited instability and modest vertical shear. Additional thunderstorms are possible across Florida and coastal Georgia where persistent easterly flow will continue to advect somewhat richer low-level moisture inland. In addition to this activity, isolated to scattered thunderstorms are possible across Georgia and the Carolinas as isentropic ascent increases with a modest low-level jet response ahead of the approaching mid-level trough. Predictability remains low with this potential as the mid-level vorticity maximum will trail well behind the cold front. Weak upper-level support combined with relatively weak isentropic ascent is the primary limiting factor for severe weather potential across Georgia and the Carolinas Wednesday afternoon/evening. ...Bentley.. 12/16/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
