A Developing Problem in the Great Plains as Climate Influences Change with Peak of Summer Arriving

High pressure ridging across a region of developing shallow soil moisture deficit where deep layer soil moisture deficit already exits indicates a flash drought risk.

AG Research: Comparing July 2010 to July 2020 for Nighttime Warmth (Crop Stress).

July 2020 Night-time Minimum Temperature in the Central U.S. Discussion: July 2010 was an unusually warm and muggy month across the Corn Belt. The warm and humid nights added to crop stress due to limited recovery from warm days. Will July 2020 have similar characteristics? The current operational forecast for July 2020 precipitation favors drier-than-normal climate in the Corn Belt (Fig. 1). The July rainfall pattern in this region is likely dependent on the interaction between the jet stream to the north and how active the tropical regime across the Gulf of Mexico to the south. In July 2010 the Corn Belt high humidity climate was helped by a consistently wetter-than-normal regime (Fig. 2). The July 2020 minimum temperature anomalies are forecast warmer-than-normal for much of the U.S. including the Corn Belt (Fig. 3). However, the strength of the anomaly is about 2/3 of the July 2010 minimum temperature anomaly regime in the Corn Belt (Fig. 4). Therefore similar to July 2010 warm/humid night stress on the Corn Belt is close but unlikely.

Fuel For La Nina In Question

Upper ocean heat anomalies became boldly negative east of the Dateline in the equatorial Pacific Ocean last month. Implied was plenty of support for La Nina ahead. However, the past couple weeks have observed the cool anomalies staring to weaken indicating and La Nina ahead would be brief and weak.
