Areas affected...Northeastern MS into northwestern AL
Concerning...Tornado Watch 76...77...
Valid 250257Z - 250400Z
The severe weather threat for Tornado Watch 76, 77 continues.
SUMMARY...Severe threat, including the potential for strong
tornadoes and damaging winds, continues across parts of northeastern
MS into northwestern AL.
DISCUSSION...Latest radar data from GWX depicts a well-organized
supercell cluster tracking east-northeastward across northeastern MS
this evening. Ahead of this storm, lower 60s dewpoints are spreading
northward in response to continued cyclogenesis to the north --
supporting surface-based inflow. With a strengthening low-level jet
over the area (70+ kt 850-mb winds) sampled by the GWX VWP,
hodographs are becoming increasingly favorable for intense
supercells (even if embedded in line segments). Given the ample
streamwsie vorticity and surface-based inflow for this storm, strong
tornadoes and damaging winds remain possible from northeastern MS
into northwestern AL.
