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.

The Great West Coast of South America Marine Heatwave
The warmest sea surface temperature anomalies (SSTA) on record for early February stretching north-to-south off the coast of Chile and Peru exceeding 3C throughout much of this region has generated. Onset of this large and intense marine heatwave (MHW) occurred in DEC-25. Strengthening continues especially along the immediate coast of Chile during the past 2 weeks. The warming is spreading equatorward. The daily Nino12 SSTA region off the northwest coast of South America is +0.63C today and 1.27C warmer than 30 days ago.
