Latest USDA weather update for western and eastern FSU

Western FSU
Mostly favourable weather prevailed, with rain in western and northern growing areas contrasting with dry conditions for much of the week in southern Russia.

A persistent blocking high over northern Eurasia continued to cause storms to drift and stall over Ukraine and northern Russia.

As a result, an additional 10 to 55mm of rain from central Ukraine into western and northern Russia sustained adequate to abundant soil moisture for filling winter wheat as well as vegetative corn, soybeans, and sunflowers in Moldova, Ukraine, and western Russia.

However, key southern Russian winter wheat areas of Rostov and Krasnodar Krai (located in the southwestern Southern District) were dry for much of the week, which enabled winter wheat maturation and drydown.

After a cool start to the week, increasingly warm weather (30-34°C) developed over much of Russia as well as western-most crop areas.

Eastern FSU
Beneficial showers continued over the region’s primary spring wheat areas, while early-season heat lingered over eastern portions of the region.

For the second consecutive week, showers and thunderstorms (10-55 mm) across northern Kazakhstan and central Russia boosted soil moisture for crop establishment.

Localized pockets of dry weather continued in Russia’s Siberia District, but most areas have sufficient soil moisture for proper spring wheat development.

Eastern-most spring wheat areas experienced daytime highs at or above 30°C, which accelerated crop development but also increased evapotranspiration rates.

Farther south, seasonable heat continued - albeit not as hot as last week - with daytime readings topping 35°C (locally as high as 40°C in Uzbekistan and 44°C in Turkmenistan) across much of the region’s southern tier.

The heat was accompanied by showers and thunderstorms (10-50 mm, locally more than 100 mm), which provided supplemental moisture for vegetative cotton and also boosted irrigation reserves.
