Fig. 1-2: Last week the U.S. was very warm particularly in the AG Belt while areas of wet weather also affected the AG Belt to the northeast Gulf States.
This week: Risk of a July drought northward into the Corn Belt is likely eliminated by gully-washer 3-6 in. rainfalls this week from Nebraska/Kansas to Iowa/Illinois. The rains follow a period of anomalous heat and dryness last week in the AG Belt (Fig. 1-2).
Days 6-10 (June 23-June 27): Borderline heat West and South U.S. while more wet weather suppresses heat in the Corn Belt.
Days 11-15 (June 28-July 2): Big warm-up in the Corn Belt and likely drier but hit-and-miss air mass thunderstorms are likely.
Early July mega-cluster: Still favoring an eastern U.S. ridge with wet weather on the back side of that ridge near or in the eastern Corn Belt.
New long-range climate forecasts through winter 2018-19 are issued this week.
