The transition from spring to summer across the northern high plains region primarily featured a building ridge of high pressure over the greater Rocky Mountains. This flow pattern steered most storm systems away from northeast Montana. D2 drought conditions encroached into the area from the northeast by mid-June and worsened to D3 conditions from Sheridan County, stretching southwest through Fort Peck Lake through the end of June. Most locations reported less than one inch of precipitation for the month while many locations in the D3 area reported less than half an inch.
