Inaugural Year-2 Ahead Climate Outlook for North America

The Climate Impact Company inaugural year-2 ahead climate forecast for North America is issued. The forecast is valid for meteorological spring 2025 through winter 2025-26. Forecast highlights include a wet spring in Texas/Louisiana, a (nationally) hotter than normal summer, warmer than normal autumn, and possibly a vigorously warm winter 2025-26 season. Important dryness leading to drought emerges in Texas during the summer season and expands to the Mid-south States by autumn. The winter 2025-26 forecast is unusually dry.

Upper Ocean Heat in Equatorial East Pacific Diminishing Fast Signaling El Nino’s Demise Ahead

The NCEP CFS V2 Nino34 SSTA forecast has relentlessly been forecasting a flip from the current strong oceanic El Nino to similarly intense La Nina by the end of 2024. Given the strength of the current El Nino and the general oceanic anomalous warmth poleward of the Pacific tropics, a rapid shift toward strong La Nina seems unrealistic. The latest NCEP CFS V2 Nino34 SSTA forecast insists on a decline in El Nino with neutral ENSO by April, weak La Nina by June, and strong La Nina by October. A recent development supportive of this forecast is the sudden loss of upper ocean heat across the equatorial Pacific Ocean.

January 2024 Global Soil Moisture Trend

Entering 2024, drought concern in the southern hemisphere was present across Brazil, South Africa, and much of Australia. Interestingly, the drought focus as mid-summer approaches in Australia shifts to the western continent as heavy rains have affected parts of the East while the wet monsoon has emerged across the North. In South America, Argentina drought is nearly dissipated although short-term forecasts are hot and dry. Meanwhile, a dry start to summertime in Brazil reverses wetter in January.
