Commodities Market Impact Weather

MINNEAPOLIS (DTN) --- Rising temperatures and chances for precipitation in the U.S. and periods of rain in the southern half of South America are the weather factors driving the markets Tuesday.

TEMPERATURES RISING IN THE MIDWEST

In the Midwest, very cold temperatures from the polar vortex are shifting eastward this week, being replaced by some very warm air. Snowfall that came for Christmas will be melting quite a bit. In addition, scattered rain showers are expected later this week and weekend with a couple of disturbances moving through, mostly along the Ohio Valley.

CENTRAL AND SOUTHERN PLAINS WARMING

Temperatures are rising above normal in the Central and Southern Plains as arctic air is moving out of the region. Several storm systems and disturbances will move through over the next week, but precipitation is going to be limited and more likely for northern areas than anywhere else. This will likely be a mix of rain and snow. Precipitation is not forecast to be very heavy or help with the drought situation.

RISING TEMPERATURES FOR NORTHERN PLAINS

The arctic air is moving out of the Northern Plains and temperatures are rising above normal. Any threat to below-normal temperatures is well off in time. A couple of systems may move through, however, and bring periods of rain and snow for the next week.

RIVER LEVELS IN THE LOWER MISSISSIPPI GETTING A BUMP THIS WEEK

Warmer air is returning to the Delta and other areas of the country, which will help to melt snow and bring more water through the Mississippi River system. Additional periods of showers are expected late this week and weekend, which will help add to the river as well. Water levels reached a peak last week, but will be helped out by a slightly active pattern going into the new year.

ONLY LIMITED SHOWERS FOR SOUTHERN BRAZIL

Scattered showers will continue in central and northern Brazil for at least the next two weeks, as is typical for this time of year. Soybeans remain in mostly favorable condition, though dryness across the far south is a little concerning for both corn and soybeans that are in reproductive stages. A cold front will move into the south with a brief period of showers Tuesday into Wednesday, but the front will move north of Rio Grande do Sul and dry out behind it. Rio Grande do Sul and eventually Parana will dry out and some concern over crop conditions continues in these states.

BRIEF SHOWERS FOR ARGENTINA

A front brought widespread showers to Argentina on Friday, but it has gotten dry behind it yet again, with dry conditions continuing through most of the week. Another shot of showers will move through this weekend, but it will get dry behind that front as well. Showers are not coming at a consistent enough clip to reduce drought or turn around crop conditions for corn and soybeans that have been significantly harmed by heat and drought this season. Planting on both remains well behind the normal pace as well.
