Rainfall was very minimal in the Argentina cornbelt today, with one station in La Pampa reporting 0.39 inches. Argentina's highs today reached the 80's to mid 90's with 70's in La Pampa, and the warmest highs in western Santiago del Estero. In Brazil, the drier soils in southern Rio Grande do Sul missed rainfall today. The heaviest rain affected western Parana, western Santa Catarina, eastern Mato Grasso do Sul, western/northern Sao Paulo, and southern Minas Gerais, with over 1.5 inches of rain in spots. Spotty showers affected Mato Grosso, Goias, and western Mato Grosso do Sul, with totals mainly under .25 inches. This recent drier weather trend in Mato Grosso has allowed farmers to quicken their soybean harvesting. According to SoNoticias, the president of the local Rural Syndicate in the municipality of Lucas do Rio Verde(central Mato Grosso) estimates its farmers have harvested over 40% of soybeans. Some of the earliest soybean planting is done here, but hot and dry weather delayed planting here too. Some fields received beneficial rains after planting while other didn't. After a wet January slowing harvest, yields are very variable and range from 9-52 bu/ac, with even individual fields varying as much as 39-52 bu/ac. Lucas do Rio Verde's soybean harvesting is expected to be done in the second half of March.
There will be heavier rain in the southern Argentina cornbelt Friday and in north/central cornbelt areas Saturday, rain mainly north of the cornbelt Sunday and Monday, and more rain in the cornbelt Tuesday. Rainfall totals will be 1-2+ inches, except lower amounts in southern Buenos Aires and La Pampa. Crop stress will continue to be reduced due to these rains. There is model disagreement, but mid-upper 90's are likely in the northern Argentina cornbelt especially Friday and Saturday. Southern Rio Grande do Sul will see rain Saturday to early Sunday and late Monday and Tuesday. Totals will mainly reach 1-2+ inches, helping stressed soils. There will be scattered showers in northern/central Brazil through Saturday, with increasing coverage Sunday and Monday. Brazil rainfall will be mainly .75-2+ inches, with less far northeast. There will be time for harvest work especially through Saturday.
For the 6-10 day outlook, the wetter pattern will persist in Argentina, with crop stress continuing to be lessened. There is model disagreement on Argentina heat potential, with northern areas getting the hottest. It will stay wet in much of Brazil, with drier conditions far northeast and far north.
For the 11-15 day outlook, there is model disagreement on Argentina heat potential, with northern areas getting the hottest. Argentina will be drier, but there will still be some rain. Brazil will be drier, giving more time for harvest work.
