Nebraska climatologist Al Dutcher forecasts the precipitation and temperature outlook through early October and examines the freeze risk prior to corn maturity for multiple hybrids and sites across Nebraska.
What's the likelihood you'll see a hard freeze prior to corn maturity? Check out the end-of-season forecast and a table showing risk of a hard freeze for various emergence dates and locations in Nebraska.
Cooler and sometimes wet conditions continue in the forecast for Nebraska. And, with Hurricane Harvey barreling into the Texas coast, there are likely to be waves of rain in the eastern Corn Belt and changing conditions that may bring an early freeze to some areas there.
Short range numerical models bring additional chances for moisture to the eastern half of the state from July 2 through early July 4, likely the best chance for moisture for northern Nebraska through next weekend. If substantial rains in excess of 2 inches fail to materialize, there is a strong possibility that moderate drought conditions will be introduced across portions of the eastern Sandhills and northeast Nebraska next week.
Above normal temperatures since June 1 have reduced accumulated GDD deficits from late April and May. Preliminary analysis suggests that GDD deficits (corn base) have been eliminated across southern Nebraska and reduced across northern Nebraska. See current GDD table.
