Severe Weather Update - May 31

A broken line of thunderstorms has erupted along the cold front across eastern/central South Dakota and into northern Nebraska. With surface winds from the southwest along the cold front, low level shear is pretty weak; combined with high LCL's due to only mid 50s dew points and you are left with fairly high based storms capable of mainly large hail. These storms should continue to develop and move southeast through the evening and into the overnight hours.

While additional thunderstorms may be able to develop during sunset along the warm front in eastern Nebraska, the most likely scenario will be for the storms along the cold front to evolve into a more linear system. These storms may be capable of damaging winds and isolated large hail as they move into northwest Iowa and adjacent areas. Additional updates are possible as storms continue to develop and move into/nearby Iowa...
