LINCOLN, Neb. (DTN) -- Prospects for timely rainfall in dry areas of South America and a strong late-winter storm system in the U.S. are the primary weather factors for the market's attention Tuesday.

VARIABLE MIDWEST PRECIPITATION

A large variance in precipitation is indicated for the Midwest in the DTN Ag Weather forecast. Moderate to heavy snow, bitter cold air and blizzard-strength winds are in store for northern and western Midwest areas, disrupting transportation and stressing livestock. Eastern Midwest areas are in line for moderate to heavy rain and flooding. This sector of the region has the potential for fieldwork delays during spring due to wet soils.

COLD, DRY IN SOUTHERN PLAINS

Cold, dry and windy conditions will dominate the Southern Plains pattern during midweek. This keeps dryness stress at a high level in winter wheat areas. The threat of fire is also elevated because of dry air, dry ground and strong winds.

BITTER COLD IN NORTHERN PLAINS

The Northern Plains region has periods of snow, very cold temperatures and strong winds during the next 24 to 48 hours. This combination is hazardous for safety and transportation and is unfavorable for livestock. The 6- to 10-day period brings additional cold along with mostly dry conditions.

FAVORABLE SOUTHERN BRAZIL RAIN CHANCE

Southern Brazil has moderate to locally heavy rainfall in store during the next seven days. In some locales, this would be the best rain in months. This event's moisture is key for avoiding further crop decline. Further north, central Brazil will see lighter showers than earlier this month. This drier pattern will favor soybean harvest progress along with continued second-crop corn (safrinha) planting.

PROMISING ARGENTINA RAIN PROSPECT

Northern and central Argentina crop areas have a promising rain prospect over the next week. Rainfall will offer marginal benefit to corn, with a higher degree of benefit for soybeans. Crop-size estimates are notably lower compared with production a year ago; further decline is likely without rainfall.
