Morning Bow Echo

Thunderstorms cleared the state during the overnight hours, but not before providing several reports of hail and damaging winds as well as a tornado report in northeastern Iowa during yesterday evening.

Early this morning there is a bow echo that is entering northwest Iowa with the potential for damaging winds in excess of 60 mph. This storm has had a history of damaging wind gusts as well as marginally severe hail. The bow echo is a line of storms extending from near Beresford, SD southwards to near Pender, NE; and is moving east/northeast at 35 mph. A Severe Thunderstorm Watch has been issued for portions of northwest Iowa until 9 am for this line of thunderstorms.

This line of storms does appear to travel towards my location, thus will plan for its' arrival between 8:30 and 9:00 AM with the likelihood of a photogenic shelf cloud.
