Today NOAA/CPC issued new long-lead probabilistic climate forecasts. Of interest, is the summertime outlook. The temperature probability forecast indicates above normal risk of anomalous warmth for all states during JUN/JUL/AUG 2021 with highest risk across the Southwest States.

The February MJO had a profound influence on the environment of the equatorial East Pacific. The (MJO) event shut-down trade winds which eased the up-welling of cool subsurface water to maintain La Nina intensity.

Despite the cold ending to meteorological winter the overall U.S. temperature rank for the just-ended winter season was 29th warmest of 127 years which is in the top 25% warmest. The Central and southeast U.S. were temperate except for chilly Texas, Oklahoma and Arkansas plus warmer-than-normal Florida. California and Maine were very warm while the remainder of the northern tier states were warmer than normal.

A spike in solar activity around the beginning of 2021 descended sharply in February. However, the overall trend of solar activity is upward as Solar Cycle 25 has initiated.
