Researchers rise to problem of predicting hail, tornadoes three weeks prematurely

A prediction lead time of about 2 to five weeks is sorely missing in present forecasting capabilities for extreme climate. Atmospheric scientists now reveal the flexibility to make skillful predictions of extreme climate throughout the Plains and southeastern United States, together with hail and tornadoes, in that coveted ”subseasonal” time scale. To do it, they use a dependable tropical climate sample known as the Madden-Julian Oscillation, which might affect climate in distant elements of the Earth.
