Not much has change since last week in terms of the outlook. The rest of June is likely to be warmer than normal with high variability of rainfall but tendency to above normal rainfall.
It appears a heat dome will be centered in the south central U.S. this summer with periods where it shifts over the corn and soybean belt and Ohio Valley. The next surge of heat will come this weekend into early next week. With these surges come a ring of fire of storms around the heat dome leading to locally heavy rainfall. However, that rain will be scattered in nature.
