The Climate Prediction Center’s March 15 outlook continues to favor dry conditions for the Southern Plains. Its summer precipitation outlook, however, has changed and is shifting the highest probabilities for below normal moisture south (Figures 1 and 2).
Climatologist Al Dutcher looks at snowpack and temperature and precipitation patterns with an eye toward the weather outlook for planting season and a glimpse toward the extended summer outlook. While patterns are still uncertain, it appears a drier trend may be developing for the summer.
As evidenced by field after field of broken corn stalks and ears lying on the ground, the Nebraska plains were swept by winds of 30-50 mph, often over a sustained period, Oct. 23-27. Two tables show the peak gusts as well as how many hours in a given day two sites experienced high winds.
On Oct. 28, the last of Nebraska's Mesonet weather stations recorded a hard freeze of 28°F, effectively bringing the state's growing season to an end. A table shows dates for 28°F and 32°F freezes as well as average dates for these thresholds for 63 sites.
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.
