The past year was the sixth warmest on record, including record-high annual temperatures in key crop areas of Europe and southern Asia.

Forecasts for more cold and snow through the end of winter mean continued drawdown of available forage and possibly more herd reduction before a new crop is harvested in late spring-early summer.

Models vary on how it will occur, but a major pattern change this week will set the stage for bringing shots of colder air into the Canadian Prairies and at least the North-Central U.S. as we head into February.

Crop region damage from storms and drought is noteworthy in the list along with hurricanes, drought and snowstorms.

A very warm and active pattern will start to end next week. A trough of low pressure in the upper levels, which has been over the North Pacific for the last couple of weeks and sent many pieces of energy through the U.S., will finally move eastward into the U.S.

The transition from La Nina to neutral conditions in the spring and summer should put the country into a typical summertime pattern, one with plenty of variability. Here's a closer look at expected conditions for the various regions for temperatures as well as precipitation.

A look at corn yields following three-year La Nina events shows either flat yields relative to average or much better than the previous year.

Recent strong storms have hit the Sierra Nevada Mountains in California with heavy snowfall. So far, the area is running well-above normal for the start of the new year. Additional heavy snowfall is expected to continue for the next couple of weeks.

La Nina's control on South American weather continues with warmer and drier conditions continuing across far southern Brazil and Argentina. Crop health has been declining in recent weeks, even though showers have moved through from time to time.

The temperature forecast for January is for much warmer air as the cold, arctic conditions that visited North America in November and December remain locked up farther north.

Intense arctic cold quickly spread through the country this week. Temperatures easily dropped 50 degrees or more in a 24-hour period or less for much of the country.

Shorter snow seasons, decline in ice cover and a loss of bird populations are a few of the highlight impact features as the far north continues to warm.

La Nina's tendency to produce hot and dry conditions across southern Brazil has started to create stress for Rio Grande do Sul's corn and soybean production in recent weeks.

Intense arctic cold will plunge through the country east of the Rockies this week. The front will cause a strong system to wind up and bomb out, creating areas of heavy snow and strong winds that are likely to produce blizzard conditions across much of the Corn Belt.

La Nina's typical influence in the weather toward hot and dry conditions for the southern half of the continent remains the prominent pattern for the rest of December.

Moisture deficits of up to 12 inches brought notable drought intensifying throughout the central U.S. over the past year.

While the country is going through a significant winter storm this week, the forecast for next week calls for arctic cold to rush through the country due to an intrusion of the polar vortex.

A very strong storm system will move through the country next week. The system will have access to plenty of moisture, creating heavy snow across the Northern Plains, and widespread precipitation elsewhere, including chances for severe weather across the South. Strong winds...
