Commodities Market Impact Weather

MINNEAPOLIS (DTN) –- A strong storm moving through the U.S. this week followed by a visit from the polar vortex next week, dryness and drought across Argentina, and better rain for Brazil are the weather factors driving the markets Thursday.

ARCTIC COLD COMING TO MIDWEST

A strong storm system continues to bring heavy snow across the northern Midwest, but will wind down over the course of the next two days. Cold air will move in behind the system and will be reinforced by a couple of very strong cold fronts next week.

CENTRAL AND SOUTHERN PLAINS EYEING POLAR VORTEX NEXT WEEK

A strong storm system has mostly left the Central and Southern Plains, but some light snow will stick around Nebraska through Friday. Very little precipitation fell in southwestern areas, which continue to be under strong influence of drought. A stronger front will move into the region early next week with some precipitation but much colder air. An even stronger front will reinforce the cold later next week that will spread through the entire region.

BLIZZARD CONTINUING IN NORTHERN PLAINS, POLAR VORTEX LOOMS

In the Northern Plains, widespread heavy snow is turning more into bursts of light to moderate snow for Thursday before phasing out into more light snow. That light snow will stick around through the weekend. Cold air is moving in behind the system, but an arctic blast coming with a cold front and the polar vortex this weekend will continue to keep the region cold through at least Christmas.

RIVER LEVELS STAYING HIGHER FOR LOWER MISSISSIPPI

A strong storm system brought widespread precipitation to river systems feeding the Mississippi River, which will help keep water levels up through the end of the year. A couple of fronts may produce more precipitation next week, also aiding water levels.

FAVORABLE WEATHER IN MOST OF BRAZIL

Scattered showers will continue in central and northern Brazil for the next week as is typical for this time of year. A front moved through southern areas on Monday, but is getting drier behind it for the rest of the week. Some showers will fill back in over the weekend, but the state of Rio Grande do Sul will see much less precipitation. Drier conditions there are somewhat concerning and could start to create some stress as rainfall has been lower than normal over the last six weeks or so. Otherwise, generally favorable weather continues for most of the corn and soybean areas.

DRY AGAIN IN ARGENTINA

A front moved through Argentina on Wednesday, but precipitation was very spotty. Drought continues to have negative influences on corn and soybean development as well as planting. Dryness is favored with increasing temperatures next week. Overall, conditions continue to be poor for corn and soybeans until precipitation becomes more consistent.
