will increase in number and intensity through the afternoon. Deep
layer shear is favorable for discrete supercells. The environment is
most favorable for very large hail...though tornadoes would be
possible with right moving supercells

wind gusts to 60 knots. A few cumulonimbi with maximum tops to
