Yesterday’s year ahead climate forecast for North America reveals a dry climate pattern setting up across the northwest Great Plains to the Ohio Valley during APR/MAY/JUN 2025 expanding northward across the Canadian Prairies during JUL/AUG/SEP 2025. The dry pattern is accompanied by anomalous heat and implies potential for a large drought developing during the 2025 warm season.

Typically, La Nina brings wet weather to Eastern Australia. The daily Nino34 SSTA descends to -0.85C and La Nina onset is imminent. Short-term heavy rains are in the forecast for Coastal Queensland. However, the week 2-4 outlook (from ECM) is widespread drier and hotter than normal across Eastern Australia, very different from a typical La Nina climate.

A strong positive phase Asia-Bering Sea-North America (+ABNA) index emerges over the next 2 weeks and cools the North Pacific which leads to (NOAA) La Nina onset and intensity increase, a warming of North America and soaking atmospheric river into the North America West Coast.
