Commodities Market Impact Weather

MINNEAPOLIS (DTN) -- A week of cold in the U.S., recent heavy rain in eastern Australia, and a drier week for South America are the weather factors driving the markets Tuesday.

WINTRY WEEK FOR MIDWEST

A weak system will pass through the Midwest on Tuesday with scattered showers, mostly in the form of snow. Light accumulations are expected. Lake-effect showers will continue afterward. Another push of very cold air will come through late week with more snow showers. Wheat is finding cause to go dormant this week.

COLD FOR CENTRAL AND SOUTHERN PLAINS

A storm brought scattered showers to the Central and Southern Plains on Monday, including areas of light to moderate snow. Temperatures well below normal continue as a couple of reinforcing shots of cold air move through this week. Temperatures will moderate next week and will go back above normal again. Wheat may be slowly slipping into dormancy in poor condition, though.

EARLY WINTER IN NORTHERN PLAINS

Light snows continue in the Northern Plains this week as a couple of reinforcing shots of cold air move through. Temperatures will start to moderate next week.

DRY IN THE DELTA

Some scattered showers went through the Delta late Monday. Recent precipitation, including what occurred with the remnants of Nicole, has benefited river levels on the Lower Mississippi. The effect is mostly temporary and falling temperatures and freezing soils will lock away more water to the river system.

DRIER IN SOUTHERN BRAZIL

Scattered showers occurred over southern Brazil this weekend but left on Monday. Showers will continue over central areas. With the recent showers, the dryness in the south will not be concerning just yet. More showers are expected next week.

ARGENTINA DRIER THIS WEEK

Scattered showers moved through Argentina over the weekend, which will help ease some of the drought concerns. Soil moisture is still below normal for most areas despite the showers. A weak front will allow for some isolated showers to return to southern areas late in the week and fill in again over the weekend before a front pushes the showers out Sunday into Monday. The dryness and drought continue to be concerns until showers become more consistent.

GETTING COLDER IN THE BLACK SEA

It was mostly dry in the Black Sea region over the weekend as some colder air started to move in. Some showers will move through later this week along with another push of cold air, which will be unfavorable for later harvest of corn and sunflowers. Wheat is starting to go dormant through the end of the month, mostly in good condition where planting was able to occur.

DRIER WEEK IN AUSTRALIA

Another round of heavy rain moved through eastern Australia over the weekend and heavy rains over the last couple of months are leading to quality concerns and flood damage to a potential record crop. Dry conditions are expected for most of the week, but another system will come through with scattered showers this weekend, keeping most areas wet.
