Climate forecasts indicate wetter weather ahead for the Brazil drought area in Q4/2025. The ECM week 3-4 forecast projects a wet anomaly across the drought area. The latest Madden Julian oscillation (MJO) forecast indicates an emerging moderate-strength phase_8 which supports a wetter climate shift for South America, specifically Brazil, by week-3.

The 15-day temperature and precipitation outlook across Brazil reflects the influence of a torrid drought on climate. Centered over the Brazil drought area, the ECM ENS forecasts extreme heat for much of the next 15 days while the rainfall forecast continues to shift into the arid category.

During the past 30 days, ECM has produced a wet bias with their rainfall forecasts in the 16-30-day timeframe. Conversely, the GFS is too dry.

Early season snow cover has developed over North/Northeast Russia. The snow cover in that region for later September is above normal. Snow cover expansion is likely. The GFS 15-day temperature anomaly forecast indicates widespread cooler than normal temperatures with snow snowfall across Northern Russia and the attendant cool air mass extending southward.
