MattPetrulli Posted March 2, 2019 Share Posted March 2, 2019 SPC issued an enhanced risk for tornadoes (which includes a 10% hatched) and for wind. As the shortwave trough moves across the lower Mississippi Valley on Sunday, a 75 to 90 kt mid-level jet will move across the Tennessee Valley. The southeastern edge of this feature will enhance ascent and aid strong deep-layer shear profiles. Due to this, a wind damage threat should develop within the squall-line by midday. At low-levels, a 40 to 60 kt jet is forecast to move eastward across south-central Alabama during the afternoon. Discrete supercells that form over the warm sector near and to the southwest of the low-level jet max will have favorable shear profiles for tornadoes. The number of tornadoes that develop will be dependent upon how many discrete cells form out ahead of the cold front. If a cluster of discrete cells can become scattered across the area with stronger instability, then there could be a small cluster of tornadoes. The greatest potential for tornadoes is currently forecast from just north of Mobile east-northeastward to the east of Columbus, Georgia. An enhanced has been added along this corridor where a potential for strong tornadoes will exist. In addition to tornadoes, wind damage and isolated large hail will also be possible with supercells. A wind damage threat should also be concentrated along the squall-line to the west. The squall-line should progress eastward across the southern Gulf Coast States and into Georgia during the late afternoon and early evening.

Indystorm Posted March 3, 2019 Share Posted March 3, 2019 The isolated storms as well as the line are both moving into areas of higher helicity as they approach Alabama. They must be watched carefully, even if lapse rates are not all that high. Link to comment Share on other sites More sharing options...
MattPetrulli Posted March 3, 2019 Author Share Posted March 3, 2019 2 isolated cells in the Panhandle and SE AL exhibiting broad rotation, along with defined superceullular structures.
