The approaching front will be a focusing mechanism
for lift which will make thunderstorms a pretty sure bet as the
front moves through. The combination of instability, shear, and
lift is right for the development of severe thunderstorms.
Supercells with all severe weather types (hail, winds, and
tornadoes) are possible within the warm sector ahead of the
front on Wednesday, while the forcing along the front will
likely produce more widespread and linear thunderstorms as it
moves through. This would focus the severe weather threat more
toward damaging winds, and for this reason we have included
damaging winds in the forecast. Again, broader severe weather
threats are possible, including heavy rainfall and possible
flash flooding, however the wind threat has the greatest
confidence at this point.
