Isolated severe storms will be possible on Saturday over parts of the Southeast. ....Synopsis and Discussion... An expansive area of strong southwest flow aloft will persist from the southern Plains into much of the East, with an amplifying upper trough over the Plains at 00Z. This wave will eject northeastward across the OH Valley, as has been the case with the previous several shortwaves. Minor height rises in a warm advection regime will occur over the Southeast during the day, but will give way to falls during the afternoon and especially overnight as the primary speed max to the north grazes the region. An effective boundary/surface trough will likely remain situated from southwest to northeast from southern LA into MS, AL, and GA, with upper 60s F dewpoints spreading north across AL and into GA. Substantial ongoing rain and storms are forecast early on Saturday near the boundary, and this activity should transition eastward through the period. An area of overlapping instability and low-level shear near a warm front could yield supercell potential, but the actual risk will depend on mesoscale factors such as boundary position. As such, will introduce low severe probabilities for wind and isolated tornadoes at this time. ...Jewell.. 11/30/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
