MINNEAPOLIS (DTN) -- Lower temperatures settling in across the eastern United States and good chances and coverage of rain in South America are the weather factors holding the market's attention Tuesday.

COLDER AND DRIER IN MIDWEST

Some isolated showers will be possible near the Great Lakes for the next couple of days, but cold air settling in will slow soil drainage with some frosts and freezes through the week in the Midwest. The cold will also slow growth on winter wheat. Temperatures will rise late this week and weekend.

SCATTERED SHOWERS FOR SOUTHERN PLAINS

A front continues to move south through the Plains and a system developing on the front should bring some scattered showers to the region through Wednesday. Cold air behind the front will bring some frosts and freezes through the week, slowing growth for winter wheat. Any precipitation would be beneficial however, as drought has been building, especially across the western areas.

COLD IN THE NORTHERN PLAINS MODERATING

Low temperatures will be in place for the couple of days but it should remain dry. Warmer weather will arrive late this week and weekend and there is a chance for a few showers going into next week. A system will likely move through during the middle of next week, but there is uncertainty in how this will develop.

SCATTERED SHOWERS FOR DELTA

A front slipping through the Delta will have some occasional showers through Thursday, but moderate amounts should stick to southern areas. Overall, harvest should not be affected very much. Lower temperatures will settle in too and the first frosts will be possible across northern areas.

DRIER IN THE SOUTHEAST

Dry weather will continue in the Southeast for the next few days before a front moves through with scattered showers on Thursday. Colder weather will follow the front going into next week.

WAVES OF LIGHT RAIN FOR PACIFIC NORTHWEST

Drought remains a large concern for winter wheat in the Pacific Northwest. A trough off the coast will bring in a few waves of light showers which may be helpful for a few areas, but more moisture is needed throughout the rest of the fall and winter.

ONLY ISOLATED SHOWERS FOR BLACK SEA

A couple of weak systems will bring some showers mostly to Ukraine this week, while Russia stays fairly dry. There continues to be dryness concerns for winter wheat establishment in these drier areas.

SHOWERS CONTINUING ACROSS BRAZIL

Scattered showers will continue daily across central Brazil for the next week, while a couple of rounds of showers are expected across southern areas as well. Overall, conditions are favorable for soybean and full-season corn planting and early growth. Some dry periods will favor winter wheat harvest over the south as well.

DAILY RAIN CHANCES FOR ARGENTINA

Isolated showers moved through Argentina this weekend and will be more widespread this week as a couple of rounds of showers are expected with some slow-moving systems. That will favor corn and soybean planting as well as immature winter wheat.
