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.
A very active weather pattern is currently impacting the central United States, including Nebraska, with repeated rainstorms. As we end the month, models hint at active weather for the western half of the state while the eastern half looks to remain dry.
It will certainly take several days of drying before most soils across the state are fit for planting, but recent models do indicate a window of opportunity for producers to make headway with their planting. The short-term forecast offers a return to normal temperatures by the end of this week with the possibility of precipitation coming back into the picture May 10.
