MINNEAPOLIS (DTN) -- Lower temperatures spreading south through the eastern United States and the end of good rain coming to Argentina are the weather factors holding the market's attention Wednesday.
COLDER TEMPERATURES MODERATING IN MIDWEST
Some isolated showers will be possible near the Great Lakes through Thursday. Cold air that has settled into the Midwest with widespread frosts and freezes will moderate through the weekend. A system will likely move through during the middle of next week, but there is uncertainty in how this will develop. Moderate precipitation could cause more delays in the harvest should it occur.
SHOWERS LEAVING SOUTHERN PLAINS
A front continues to move south through the Plains with some scattered showers in Texas on Wednesday. Cold air behind the front will bring some frosts and freezes during the next couple of mornings, slowing growth for winter wheat. The precipitation is beneficial however, as drought has been building.
NORTHERN PLAINS WARMING UP
Temperatures will be on a warming trend for the Northern Plains through the weekend. A system will likely move through during the middle of next week, but there is uncertainty in how this will develop. Seemingly everything is on the table in terms of precipitation and temperatures. But the most likely scenario is for moderate precipitation to move through with falling temperatures and a turn to snow, which could affect the remaining corn harvest.
SCATTERED SHOWERS LEAVING DELTA
Scattered showers in the Delta continue into Thursday, but harvest should not be affected very much. Lower temperatures should slow growth on winter wheat through the weekend before temperatures rise.
HARVEST DELAYS POSSIBLE IN SOUTHEAST
Scattered showers will move through the Southeast Thursday but more so Friday into Saturday and could affect cotton harvest. Lower temperatures will follow the system going into next week.
WAVES OF LIGHT RAIN FOR PACIFIC NORTHWEST
Drought remains a large concern winter wheat in the Pacific Northwest. A trough off the coast will bring in a few waves of light showers during the next week, which may be helpful for a few areas. But more moisture is needed throughout the rest of the fall and winter.
ONLY ISOLATED SHOWERS FOR BLACK SEA
A couple of weak systems will bring some showers mostly to Ukraine this week, while Russia stays fairly dry. There continues to be dryness concerns for winter wheat establishment in these drier areas and time is running out for beneficial moisture before dormancy.
SHOWERS CONTINUING ACROSS BRAZIL
Daily scattered showers will continue across central Brazil for the next week, while a couple rounds of showers are expected across southern areas as well. Overall, conditions are favorable for soybean and full-season corn planting and early growth. Some dry periods will favor winter wheat harvest over the south as well.
RUN OF GOOD RAIN ENDING FOR ARGENTINA
Widespread showers in Argentina have and will move through during the next few days. That will favor corn and soybean planting as well as immature winter wheat. Drier conditions are expected during the weekend, but some isolated showers may pop back up next week, especially over western areas.
