Note DetailWarmer Than Usual?

Warmer than usual conditions expected throughout
the next 2 weeks will have a mixed impact on
crops.  Well established crops are likely to
benefit, but heat can stress poorly rooted plants.
Generally, temperatures slightly warmer than normal
before the 4th of July are of benefit to yield and
detrimental to crops thereafter.  The RI (index of
rain potential in the Midwest) has declined from
the multi-year peak of the past few weeks to near
normal.  The National Weather Service outlook for
July slightly favors temperatures in the coolest
1/3 of all years… desirable should this become the
reality.      – Elwynn
