July 14th was a day that had a lot of promise. I didn’t think there was a tremendous tornado threat with the relatively weak low level shear from surface through 850 MB, but overall shear, moisture and instability were quite supportive of nicely structured supercells. It did not disappoint! We had several nice supercell storms to watch. The first storm of the day was an LP, then classic supercell, then almost died as it ingested tons of dry air, and finally came back to life and became the storm of the day. A couple other supercells were also very pretty and quite severe. Most storms produced hail up to baseball size and were very electrified as well.
