Commodities Market Impact Weather

MINNEAPOLIS (DTN) -- Arctic air and a storm system along it for the Midsouth and dryness forecast in southern South America are the weather factors holding the market's attention Thursday.

ARCTIC AIR SETTLES INTO MIDWEST

Arctic air has settled into the Midwest for Thursday and Friday. Temperatures will bounce around afterward through the end of January as a few systems come and go.

SOUTHERN PLAINS CHANCE FOR SHOWERS NEXT WEEK

Arctic air in the Southern Plains will be brief with warmer temperatures moving back in for what appears to be an extended time next week. Dryness will continue to have a negative impact on drought, especially in the western half of the region. But there may be a chance for at least some precipitation in the middle of next week.

PRECIPITATION ENDING FOR PACIFIC NORTHWEST ON FRIDAY

Precipitation continues in the Pacific Northwest through Friday, helping to ease drought. Afterwards, the pattern is likely to take a turn toward drier.

RISING TEMPERATURES FOR NORTHERN PLAINS NEXT WEEK

Arctic temperatures will be around the Northern Plains through Monday. Colder air will push east early next week, and models are forecasting above normal temperatures for the middle of January, which will be a welcome reprieve from the arctic cold. The warm air may not last that long, however.

WARMUP COMING TO CANADIAN PRAIRIES NEXT WEEK

Arctic temperatures will be around the Canadian Prairies through the weekend. Afterwards, the region is forecast to go on a warming trend for the middle of January which may not last for an extended period but will be a reprieve from the arctic cold of the previous few weeks.

CENTRAL, NORTHERN BRAZIL STAYING WET

Dry conditions over southern Brazil are a major concern for reproductive to filling corn and soybeans, even with showers that have occurred over the last several days. Showers may continue in the state of Parana through the weekend, which would be favorable for some of the current crop. Scattered showers will continue over central and northern areas for the next week, which could delay maturation and early harvest of soybeans.

HOT AND DRY IN ARGENTINA

Recent showers in Argentina have been overall inadequate for development in reproductive corn and soybeans. Another dry trend sets up for the country with temperatures in the 90s through the weekend and pushing 100F next week, which will cause further stress. There is still time for the weather to turn around in January to avert disaster for the later-planted crop, but the country continues to see a poor outlook for at least the next 10 days.
