Stratospheric Cooling/La Nina Climate Strengthening: Trend Is Away from Important Cold East U.S. in January

In a new twist, ECM is forecasting a cold stratosphere across the polar region and eastern North America in the 11-15-day period. Elusive stratospheric warming shifts to Eurasia. Beneath the cold stratosphere, GFS indicates a mild ridge pattern in the East U.S. instead of an evolving polar vortex pattern as previously reported.

La Nina Has Generated; Intensifying Rapidly!

The daily Nino34 SSTA has cooled to -1.06C qualifying as a moderate La Nina signature. The cooling is remarkable with a 30-day change of a stunning -0.81C. The subsurface is as impressive as a strong cool anomaly intensified across the equatorial East Pacific and upper ocean heat east of the Dateline has cooled to a peak for the evolution of La Nina during 2024.

Dealing With Cold Weather After Holiday Season in U.S.

An expected cold change in January for North America is indicated by ECMWF which is vividly much colder in the extended range outlook. Most of the precipitation across the Northern U.S. is snow helping to enhance the cold.

Brazil Wet Bias GFS/ECM Forecasts; Machine Learning Outlooks Gain Visibility

ECM has carried a wet bias with their 15-day operational outlooks throughout mid-to-late spring and early summer. Recently, GFS wet bias has (also) increased and is similar to ECM. Presented is an excellent opportunity for machine learning forecasts to compete with GFS and ECM as they may understand the wet bias and make adjustments to the operational forecast.
