The mega-cluster ensemble indicates an area of cold weather in Russia may strengthen and intensify over the next 15 days driven in-part by above normal snow cover which recently reached Eastern Europe.

The Climate Impact Company constructed analog (CIC-CA) climate forecast for South America during meteorological summer 2022-23 indicates persistent anomalous heat and dryness in Argentina where flash drought is quite possible. The dryness extends to Southeast Brazil although less consistent. Far Southeast Brazil has a drought risk for summer 2022-23.

La Nina is moderate-to-strong enjoying a 3rd peak in intensity of the 2020-22 cold ENSO regime. However, dynamic and statistical ENSO phase forecast models are agreeable to La Nina ending in early 2023 coinciding with demise of negative Indian Ocean dipole (-IOD). However, the La Nina climate is unusually strong and could linger to the mid-point of 2023. El Nino remains a possibility for later 2023.
