Some weather comments.

We were surprised by the amount of snow that fell over the weekend along a band thast extended from eastern South Dakota eastward across southen Minnesota into Wisconsin. Snowfall totalts of 6-12 inches were reported in this region with melted amounts of .25-1.00 inch. Certainly some very welcome precipitation for this area but not a sign of a significant change in the pattern. We expect the weather pattern to continue to feature overall drier than normal condions to the west of the Mississippi River with extreme dryness in parts of the plains winter wheat belt. We are also concerned about some potential strong winds developing at times in the plains out ahead of these fast moving and moisture limited storm systems. This could raise the issue of blowouts on some of the poorly established wheat fields. It appears that this overall dry pattern west of the Mississippi River could be with us for much of the winter season. We remain very concerned about soil moisture conditions going into the 2013 growing season for much of the central US except for the eastern Midwest and the Delta states where topsoil moisture conditions have improved.

Across South America wet weather conditions remain a concern in central Argentina. After a dry weekend there appears to be two signiifcant rain events this week. One early in the week and one later in the week. This will continue to disrupt and delay corn and soybean planting with increasing concern that some corn acreage may have to be shifted to soybeans. This wet weather pattern has also impacted the quality and the harvest of the winter wheat crop with significant harvest losses expected. The weather patterns have generally improved in Brazil with more rain now falling in Rio Grande do Sul and Parana where it had been dry. Rainfall has diminished recently in the Mato Grosso. However we do expect to see some pickup in rainfall in this region during the latter half of the week.

I farm in northern Minnesota and this past fall I noticed that swamps I have farmed around for as long as I can remember were absolutely bone dry and I could run the combine into and across them without worry of getting stuck. The only reason we got relatively better than average yield on corn and beans was due to the ground water....lower ground was outstanding, lighter ground and hillsides were nothing to bother with...just pick up the head and move out....but all that ground water is now gone. We should have 2 to 3 foot of snow on the ground about this time of year and we barely have 2 to 3 inches of snow. If we don't start receiving some precip soon, I going to be wishing I could have my 2012 crop in 2013 again. Could be a very ugly scenario on the horizon.

Lack of subsoil moisture is a big concern and that was a prime weather topic at the DTN/Progresssive Farmer Ag Summit this week.
