Drier, somewhat cooler conditions followed early-week
showers, maintaining mostly favorable prospects for summer
A cold front triggered widespread showers and
thunderstorms (10-70 mm, locally more) early in the period
across Russia and Belarus, sustaining adequate to abundant
moisture supplies for reproductive summer crops.
The front also
brought an end to the short-lived but intense mid-July heat wave,
with daytime highs slipping below 35°C until week’s end.
Consequently, corn and sunflowers progressed through
reproduction with little - if any - additional heat stress,
though some yield losses from the recent hot spell are likely in
Corn in Russia’s Southern District was
subjected to as many as 6 days of high heat (35-41°C) in mid- to
late-July as the crop progressed through the tassel and silk stages
Meanwhile, the sunny, warm weather later in
the week favored winter wheat harvesting and enabled field
preparations in advance of winter wheat planting, which
typically occurs in late August and September.
favorably wet summer to date, localized short-term dryness has
developed in west-central Ukraine; over the past 30 days, this
region has reported less than 50 percent of normal rainfall,
reducing moisture supplies for reproductive corn and soybeans.
Widespread rain and near- to below-normal temperatures
maintained favorable prospects for spring wheat, while
increasing heat accelerated cotton into the open-boll stage of
development in the south.
Another round of showers and
thunderstorms (10-50 mm, locally more) over northern
Kazakhstan and adjacent portions of central Russia maintained
good to excellent yield prospects for flowering to filling spring
Furthermore, heat has not been an issue due to the
cloudy, rainy weather, with temperatures averaging up to 2°C
below normal for the week.
However, drier weather will be
needed soon to maintain the current favorable crop projections.
Farther south, increasing heat (daytime highs 38-42°C) in
Uzbekistan accelerated cotton into the open-boll stage of
development, likely putting much of the crop past the point of
significant yield impacts from this week’s above-normal
temperatures (1-2°C above normal).
