Several small disturbances will move across the northern tier of the U.S. and southern Canada for the next week.

La Nina-influenced rain washes away world wheat market hopes for a big supply from Down Under.

The Australia Bureau of Meteorology declared La Nina to be in effect on Nov. 23. With both the Australians and Americans agreeing on the state of ocean temperatures in the Pacific, the focus turns toward the impact on worldwide agriculture for the next few months.

Limited Northern Plains drought easing and Southwest Plains drought development expected through the 2021-22 winter season. La Nina is driving the wide variability.

Dryness and drought have been building over portions of the Central and Southern Plains in recent months. While an active pattern will keep fronts moving across the country going into December, there is little indication that they will produce significant precipitation for winter...

Very warm days and nights favored U.S. row crops in their final stages.

October was a very warm month overall, but November is already having its ups and downs. That fall-like pattern looks to continue for the rest of the month.

Timely rainfall in Australia and Argentina results in a large total wheat crop as harvest gets underway.

A strong cold front with the coldest air of the season to date is settling in across the eastern half of the U.S. Widespread frosts and freezes will continue for much of the week before temperatures moderate.

Rain has saturated and sometimes flooded soils during the last two weeks, making it difficult to harvest effectively. How does soil dry out and what determines its drainage speed? And how is it different from spring to fall?

September and October rains have notably eased the worst drought in two decades over the Northern Plains.

A system during the weekend brought widespread heavy rain to much of the Corn Belt and another moving through this week will add to the totals, keep soils wet, and delay the corn and soybean harvest. A mix of adverse conditions affect both hard red winter and soft red...

Southern Plains winter wheat faces moisture uncertainty due to La Nina's influence through the 2021-22 winter.

A system will move through the Corn Belt this week and produce some locally moderate rainfall. Additional moderate rainfall will be possible across the southern Corn Belt this weekend into next week. But, overall, harvest should progress along well.

A mid-October storm system brought mixed rainfall to Southern Plains wheat areas.

After two systems brought some severe weather and moderate to heavy rains across the Plains and Midwest the last couple of days, the next one will cover a much broader area with more significant impacts.

Pacific Ocean temperature and atmospheric indicators both show a strengthening La Nina pattern.

Models are developing a strong trough of low pressure in the western U.S. that could induce a strong storm system in the Plains in the middle of next week.

A hot and dry finish to the growing season brings the potential for some loss in Midwest row-crop yields.

A strong ridge of high pressure developing from Hudson Bay down into the Midwest will create a block for a trough of low pressure in western North America. But a weakness on the southern end of this ridge will allow a system to pass through the Midwest with showers later in...
