A long duration of a thunderstorm complex that developed across northwest Minnesota early Tuesday morning, July 19th, continued to develop south and southeast across central, and eventually east central Minnesota by midday.
This storm had a persistent circulation which continued slowly southeast into the Twin Cities Metro Area and produced numerous dime to half dollar size hail stones across mainly the northern and eastern portion of the cities. In addition to the hail, several spotters observed a persistent Wall Cloud as it moved across the metropolitan area.
Some minor ponding of water on area streets was noted in the Twin Cities.
