D3/D4 drought is present across North Dakota, northwest South Dakota and into southern Canada (Fig. 1). D3/D4 drought conditions during summertime do not erode unless an interaction between the prevailing storm track and tropical moisture (or direct impact from a tropical cyclone) occurs. Interaction with tropical moisture for storms passing the northern Great Plains will have to wait until late summer. As a result, harsh drought continues in this region for the next 8-10 weeks (at least).
