Arctic Cold Spreading East

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 Monday.

WINTRY WEEK FOR MIDWEST

A system brought showers to southern areas of the Midwest over the weekend behind the cold front that has brought arctic cold temperatures to the region. A weak system will pass through Monday into Tuesday with scattered showers, mostly in the form of snow. Lake-effect snows 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 WITH SNOW FOR CENTRAL AND SOUTHERN PLAINS

Scattered showers fell over southeastern areas of the Plains on Friday as arctic cold air moved in for the weekend. A storm is developing over Texas on Monday with a mix of scattered showers. Some snow accumulations will be possible across wheat country but will not be much help with temperatures well-below normal continuing 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.

WINTERTIME IN NORTHERN PLAINS

Outside of some isolated snows, it was mostly dry in the Northern Plains over the weekend with bitterly cold temperatures. Light snows may come at times this week as a couple of reinforcing shots of cold air move through. Temperatures will start to moderate next week.

LIMITED SHOWERS FOR THE DELTA

Some scattered showers went through the Delta over the weekend and more will go through 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 AGAIN

Scattered showers occurred over southern Brazil this weekend, which is important since a cold front moving through will leave the region dry after Monday for the following week. Showers will continue over central areas. With good moisture over the weekend, the dryness in the south will not be concerning just yet. More showers are expected next week.

ANOTHER BRIEF SHOT AT RAIN FOR ARGENTINA

Scattered showers moved through Argentina this weekend, which will help to ease some of the drought concerns, but soil moisture is still well below normal for most areas despite the showers. A front moved through on Sunday, which is clearing out the country and leaving it dry for most of the week. 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 another front clears out the showers. 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 likely to start going 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.
