It was interesting to note that many of these tornadoes occurred in the morning hours on April 28th, showing just how strong this system was as that is typically the time of day when there is the least amount of instability in the atmosphere. The strongest tornado was the EF-2 that was on the ground for 33.2 miles from Rockingham County to Shenandoah County.
