Commodities Market Impact Weather

MINNEAPOLIS (DTN) -- A strong storm moving through the West and a return to dryness over Argentina and southern Brazil are the weather factors holding the market's attention Tuesday.

BRIEF HEAT FOR MIDWEST, THEN RAIN

In the Midwest, a system brought a band of heavy snow across the north and strong thunderstorms to the south last Friday and Saturday, with a couple of devastating tornadoes. The region continues to be active with near-record highs on Wednesday, then another system bringing scattered showers through. The front to the system will not clear the region and another system will develop more showers Friday into Saturday. An active upper-air pattern will continue to produce a couple more storm systems going into next week as well.

STRONG WINDS DRY SOUTHERN PLAINS WHEAT

A system will move through the Central Plains on Wednesday with strong winds, but there will be little shower activity with it outside of Nebraska. Winds gusting more than 70 miles per hour at times in some areas will continue to dry out soils for winter wheat that has yet to go dormant. The front will remain over southern portions of the region through the weekend and there should be some showers that develop along it. Western areas are thirsty for rain, but there is only a small chance that this region sees any meaningful precipitation from the lingering front. Dryness is likely to continue build drought in the region instead.

ROUNDS OF GOOD PRECIPITATION FOR PNW

Scattered showers developed in the Pacific Northwest during the weekend with some good precipitation in some of the valleys. A strong trough will continue to produce more widespread precipitation Tuesday and an active upper-air pattern will produce more showers throughout the next 10 days as well, helping to increase moisture for dormant wheat.

SOUTHERN BRAZIL DRYING OUT AGAIN

Showers have built back into southern Brazil, but that will be brief and the region will go dry again on Wednesday, lasting for about a week. The rainfall is briefly favorable for developing to reproductive corn and soybeans, but not enough. Central Brazil continues to see daily shower chances for the foreseeable future, benefiting developing to reproductive corn and soybeans.

DRYNESS RETURNING TO ARGENTINA

Isolated to scattered showers developed over Argentina this past weekend and continue into Wednesday before dryness settles back in. The showers have benefited developing corn and soybeans in areas that were hit, which includes the higher production areas around Cordoba. Showers may start to redevelop this weekend over southern areas, but that is not guaranteed.

FAVORABLE HARVEST CONDITIONS FOR EASTERN AUSTRALIA

Mostly dry weather occurred this weekend in eastern Australia, with more favorable conditions for winter wheat and canola harvest. There may be some isolated showers through the week, but most areas should find favorable conditions. Sunshine should help cotton and sorghum development as well.
