Weather forecast office sourcewfo_sourceCOOP Observer
Episode narrativeepisode_narrativeThe general flow pattern over the Northern Plains was very weak. However, by mid afternoon on the 11th, a few thunderstorms flared up along a line from Hillsboro (ND) to Erskine (MN). As these storms died off they sent out numerous outflow boundaries that showed up very well on radar. Two of these outflow boundaries intersected just southwest of Grand Forks, causing another thunderstorm cell to flare up. This storm moved across the southern edge of the city of Grand Forks, producing some large hail and localized gusty winds.
Event narrativeevent_narrativeAbout five inches of rain fell over a three hour period.
