24-HOUR PRECIPITATION ENDING AT 7PM CDT MONDAY...SIOUX CITY, IA 0.61 INCHES

US OUTLOOK AND MODEL DISCUSSION:

There is a ridge in the Central and East with a trough in western Canada, another in the Pacific Northwest, a small one in the Plains, and another ridge over the Gulf of Alaska. The two smaller troughs will move eastward early this week. Meanwhile, the western Canada trough will dig into the Pacific Northwest this week. That one is forecast to move eastward next week.

The U.S. and European models are similar, but are different in how they treat a system next week. I will use a blend but favor the European.

A very weak system will move through the country this weekend with some areas of showers. But it should be a system that moves through next week that produces more widespread precipitation. Temperatures should be above-normal for most of the country, with some milder air likely moving into the West that could move eastward behind next week's system.

MAJOR WORLD HIGHLIGHTS/IMPACT:

NORTHERN PLAINS (LIVESTOCK/WHEAT/CORN/SOYBEANS): Some showers and a little snow moved through eastern areas on Monday. A few more isolated showers will be possible through Wednesday. Though there might have been some disruption to fieldwork, there have been some other areas that have stayed relatively dry.

There may be some more showers this weekend into early next week that could cause some more disruption as well, but those are uncertain right now.

CENTRAL/SOUTHERN PLAINS (LIVESTOCK/CORN/SOYBEANS/WINTER WHEAT): A system brought widespread showers through the region, which will phase out on Tuesday.

Though some will be delayed from doing fieldwork, others will be welcoming the rain for winter wheat establishment. A couple of other systems will be moving Friday, this weekend, and early next week which could cause further delays as well.

MIDWEST (LIVESTOCK/CORN/SOYBEANS/WINTER WHEAT): It was warm and mostly dry this weekend, which has allowed for a lot of fieldwork to be done. A small system is moving through the northwest with some showers on Tuesday. A front will move through Wednesday and Thursday with a few showers. And more showers may spread through the region over the weekend as well. Despite all of these opportunities for rain, amounts should be light, allowing for more fieldwork to be done this week. A better chance for more widespread precipitation comes with a system early- to mid-next week.

DELTA (SOYBEANS/COTTON/TRANSPORTATION): Dryness and drought continue to be issues across much of the region, but are allowing fieldwork to finish up.

However, water levels on the Mississippi River are falling and could be a concern in November if the dryness continues. Some showers will likely go through this weekend, but would be mostly light. Another front should go through next week as well, but may not bring through much heavy rain like the region needs.

BRAZIL (WHEAT/SOYBEANS/CORN): Heavy rain has been an issue in southern Brazil so far this season, but showers should be lighter for the next week. Instead, a front has stalled in central Brazil, which will produce some decent coverage of showers throughout the week. That is sorely needed for soybean planting and establishment.

ARGENTINA (WINTER WHEAT/CORN): Some spotty showers will occur throughout the week, maintaining mostly good soil moisture throughout the country.

Temperatures have been cold. Though frosts did not occur this weekend, the cold is leading to slower development on wheat and corn. Colder air continues early this week before moderating back to normal for later this week. However, another system moving through early next week could lead to more cold air moving in.

EUROPE (WINTER WHEAT): Widespread showers moved across the continent over the weekend, though Spain saw dry conditions, which has been too common this fall. Some isolated showers will move through this week, but it should be much drier. Dryness continues to be an issue in many areas of Europe despite some recent rain.

BLACK SEA (WINTER WHEAT): Though there have been a few showers in Ukraine, drier conditions were more common in the Black Sea region this weekend. Some spotty showers remain possible in Ukraine, but western Russia looks to remain drier. Soil moisture is favorable in Ukraine, but not farther east, which is concerning for winter wheat establishment.

AUSTRALIA (WINTER WHEAT/CANOLA): Scattered showers moved through the eastern half of Australia over the weekend, but will end the run of rain in Queensland, which has seen beneficial rainfall lately. Showers will mostly fall over the Outback this week, but a system later this week could bring some showers to eastern areas Friday through the weekend. Any rain would be beneficial for filling winter wheat and canola.

CHINA (CORN/SOYBEANS/WINTER WHEAT/CANOLA): Conditions have been favorable in central and northeast China for corn and soybean harvest for quite some time.

Winter wheat and canola in south-central China would benefit from more rain, which is forecast to occur this weekend.
