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.

Subsurface Equatorial Pacific Looking El Nino-like; Surface and Atmosphere Linger La Nina
Right now, the leaning-edge of a Kelvin Wave shifting through the eastern equatorial Pacific during the past few weeks has weakened just before reaching the northwest coast of South America. A new Kelvin Wave has strengthened and shifted just east of the Dateline. A westerly wind burst associated with the new Kelvin Wave is present just west of the Dateline.
