Increasing showers over western and southern portions of the region contrasted with hot, dryconditions in eastern growing areas.
Moderate to heavy showers (10-95 mm) associated with a slow-moving storm system developed from Ukraine and Belarus into north-western Russia, boosting soil moisture for heading winter grains as well as emerging spring grains, corn, and sunflowers.
However, rain bypassed areas from Moldova northward through-west-central Ukraine, enabling fieldwork but reducing topsoil moisture for summer crops.
In southern Russia, increasing rainfall (10-30 mm) eased concerns over short-term dryness and improved prospects for flowering to filling winter wheat.
Although this week’s rain missed the Krasnodar Oblast in the southwestern corner of the Southern District, heavy showers and thunderstorms (25-50 mm) developed over this key wheat area at the end of the period (May 31 – June 1).
Meanwhile, sunny skies and daytime temperatures in the lower to middle 30s (degrees C) increased stress on filling winter crops from the southern Central District into the southern Volga District, though the greatest heat (34- 36°C) was generally outside of major winter wheat areas.
A much-needed break from recent heavy rain arrived in central and western spring wheat areas.
A very wet May concluded with a welcomed respite in northern Kazakhstan and the southern Urals District in Russia, with rainfall during the monitoring period generally totalling less than 5 mm.
Producers in these locales have struggled to plant spring wheat, as preliminary estimates for May indicated rainfall totalled 200 to 350 percent of normal for the month.
In contrast, 10 to 50 mm of rain (locally more) improved soil moisture for spring wheat establishment in the Siberia District, particularly in southern growing areas (Altai Krai Oblast).
Meanwhile, mostly sunny skies promoted the development of recently-planted cotton across Uzbekistan and Tajikistan, though variable light to moderate showers (1-15 mm) reduced irrigation requirements.
