A dryline out ahead of an approaching upper level low pressure system approached the area from the west.  As the dryline interacted with a destabilizing airmass and plenty of shear, isolated severe thunderstorms formed and produced mainly large hail on March 22.  A dust storm also developed and impacted the area from Sweetwater south to Water Valley with visibilities below 250 yards at times.
On March 24, the same upper level low pressure system caused another disturbance to track across the area along with the dryline.  As these systems interacted with an unstable and highly sheared storm environment, severe storms erupted across the Northwest Hill Country.  One of these supercell thunderstorms produced a very large hail from golf ball to baseball size near Junction.  Two funnel clouds were reported near Roosevelt.
