Torrid dryness across Northeast Argentina continues during early February. The outlook into early next week maintains the dry pattern. However, an upper trough approaches from the west causing significant rain in Argentina during the medium range. The forecast trend is wetter.

Europe East selected cities (Berlin, Munich, Vienna, and Milan) observed an exceptionally cold January with HDD count averaging 13% colder than normal while Europe West selected cities (Glasgow, Heathrow, Paris, Dusseldorf, and Berlin) were much closer to normal.

In March, ECMWF crests an upper ridge across the Southeast U.S. which leads to high risk of unusually warm early spring climate for the Southeast and Mid-Atlantic States. In April, the warm ridge shifts westward and settles on the southern Great Plains where dry and warm mid-spring weather is likely. Late meteorological spring brings an upper ridge to the Great Basin promoting dry and very warm climate across the West and Southwest U.S.

Extreme dryness (and heat) has afflicted Northeast Argentina during the past 2 weeks. However, changes are on the way as the 8-14-day forecast equally weighting GFS and ECM shifts heavy rain across the Northeast Argentina dry zone while East Brazil turns drier. The catalyst to the recent heavy rains across northwest and west continent is El Nino-like warming of the ocean surface off the northwest coast of South America. The rains shift eastward later next week.
