Harvest season outlook: below normal temperature, rainfall heading into harvest season

Harvest Season Outlook Below normal temperature and rainfall heading into harvest season

It's looking like the pattern of normal- to below-normal temperatures along with below-normal rainfall will continue through most of the month of September, with week-to-week variability. September Temperature Outlook Blue = Below Normal Temperatures Expected September Rainfall Outlook Brown = Below Normal Rainfall Green = Above Normal Rainfall (Primarily Due to Harvey) In fact, in the following 46-day precipitation anomaly images, areas shaded in darker shades of brown are expected to experience well-below-normal rainfall. The area of blue is rainfall associated with the remains of Harvey. Other than Harvey-impacted areas, note that almost the entire primary corn belt, and especially core corn-producing areas, are expected to receive well-below-normal rainfall. 46-Day Rainfall Anomaly Temperatures are expected to average below normal, but with week-to-week variability. The area most likely to experience below-normal readings is the eastern corn belt. It is interesting to see that the areas that are currently to most dry -- including Southeast Iowa -- could average warmer than surrounding areas. 46-Day Temperature Anomaly Blue = Cooler than normal Brown = Warmer than normal   There are some signs that temperatures could trend back closer to normal heading into October and November and there could be an uptick in precipitation.
