NOAA/CPC identifies many June historic weather and climate events occurring during June 2021. The June 2021 upper air pattern provided by the International Research Institute for Climate and Society helps to explain the super warmth.

Profound drought continues across the western and north-central portion of the U.S. Rainfall deficits are routinely 9-12 inches and sometimes >15 inches sprawled across the western states to the Dakotas and Minnesota. The 2-week trend indicates the rainfall shortages are steady except increasing in the Columbia Basin and the Upper Midwest particularly Minnesota into northern Iowa.

The deep tropics of the North Atlantic basin are becoming somewhat warmer than normal. SSTA of >1C is considered a moderate warm anomaly and much of the deep tropics have recently reached that threshold. Robust warm anomalies of >2C rest on the equator. Anomalous warm SSTA in this region are generally well-correlated with increased convection (and tropical cyclone/hurricane risk) especially if the proper atmospheric conditions are present.
