Wet spring, warm summer?

A climatologist says some parts of the Corn Belt have had a top 10 wettest start to a growing season.

Iowa’s Justin Glisan says if that trend continues, “That would be a lot of moisture at that 150-to-200% of normal.”

He tells Brownfield a warm-up period is expected soon. “We are seeing a warmer signal built in, and then shifting towards near-normal rainfall potential throughout June.”

Glisan says the transition to La Nina helped shift the southern storm flow to the central and northern crop growing states. “We’re shifting from a strong El Nino and winter that gave us the second warmest winter on record to the potential of a weak to moderate La Nina in the summertime.”

He says moving forward, summer precipitation is likely to be driven by smaller-scale thunderstorms.
