Mar. 23 Severe Weather Update #1

A Tornado Watch has been issued for portions of western Iowa, this watch will be in effect until 10:00 PM tonight for those included. For more details please see SPC Watch #55. A complex of severe and now tornadic thunderstorms has increased in coverage across eastern and northern Nebraska. These storms will continue to move north/northeast and progress eastward with the movement of a dryline/cold front that is associated with the strong low pressure system over the NE/SD borders.

These storms are likely to remain severe/tornadic through the evening and into the early nighttime hours given favorable shear values and sufficient instability. The line should move into Iowa after 6 PM, where the risk of hail and damaging winds, along with the potential for a tornado should still exist. Additional updates are likely this evening...
