System Moving Through the Plains

MINNEAPOLIS (DTN) -- A large storm that will have major weather impacts across the Eastern U.S. and better than normal rainfall in South America are the weather factors holding the market's attention Wednesday.

STORM SYSTEM MOVING INTO MIDWEST

A large storm moving into the Plains will bring widespread showers to the Midwest Wednesday and Thursday. Snow is likely to wrap around the backside of the system around Minnesota with potential accumulation. Winds will also be an issue with the system. A secondary system will move through over the weekend and add more precipitation to the region, with snow accumulations possible across the north.

SOUTHWESTERN PLAINS MISSING RAINS

Poor conditions continue for winter wheat in western areas of the Southern Plains while eastern areas are faring better. A system will move through on Wednesday, bringing scattered showers, but only to eastern areas while western areas remain dry. Strong winds may also develop behind the system, helping to dry out soils further. Overall conditions continue to be unfavorable for winter wheat in the west.

POTENTIAL BLIZZARD FOR NORTHERN PLAINS

A system is moving through the Northern Plains Wednesday with scattered moderate rain. The system should wrap up over Minnesota on Thursday, bringing snow to the region Thursday into Friday. Strong winds will also coincide with the snow, causing blizzard conditions, drifting snow, and impacting the remaining corn harvest. A clipper-like system will move through behind it on Saturday with another stripe of snow possible across the region.

BRIEF CHANCE FOR RAIN IN DELTA

A system will bring scattered showers through the Delta late Wednesday night into Thursday, benefiting winter wheat establishment but could impact the remaining harvest.

BRIEF FRONT MOVING THROUGH SOUTHEAST THURSDAY

A front will move through the Southeast Thursday with scattered showers that negatively could impact harvest. But drier weather will follow so this should be a brief occurrence.

WAVES OF LIGHT PRECIPITATION FOR PACIFIC NORTHWEST

Several waves of precipitation will move through the Pacific Northwest over the next week, each bringing potential for helpful showers. But most areas are likely to only see light precipitation and cooler temperatures through the week will slow growth on wheat.

DRYNESS CONCERNS FOR BLACK SEA

Some showers moved through Ukraine and western Russia over the last few days but have not been enough to reverse the dryness so far this fall for winter wheat establishment. Mostly dry weather through the weekend will not be beneficial and temperatures are forecast to fall early next week as a fairly dry system moves through.

DAILY SHOWERS CONTINUING ACROSS BRAZIL

Daily scattered showers will continue across central Brazil for the next week. Dryness over Rio Grande do Sul is the only area with detrimental conditions for the foreseeable future. The dryness will help with the remaining wheat harvest. But scattered showers are likely to move through southern areas over the weekend.

WIDESPREAD SHOWERS FOR ARGENTINA BY THE WEEKEND

Isolated showers have been popping up across Argentina through the week, mostly for the drier western areas, keeping soils from getting too dry. A system should push through the country over the weekend and bring widespread scattered showers, which would be favorable for corn and soybean planting and early growth. It may start to get drier after the front pushes through.

WET HARVEST CONDITIONS FOR EASTERN AUSTRALIA

Systems moving through eastern Australia since last week continue to provide good moisture for summer cotton and sorghum but putting some pressure on wheat and canola harvest. Another large system will move through on Thursday before the region goes on a drier trend next week.
