A team of researchers in the US (Colorado State University, Stoney Brook University) used a reliable tropical weather pattern called the Madden-Julian Oscillation, which can influence weather in distant parts of the Earth, to demonstrate the ability to make skillful predictions of severe weather across the Plains and southeastern United States, including hail and tornadoes, in 2-to-5-weeks-in-advance period. They validated their predictions using available datasets looking at what the Madden-Julian Oscillation was doing about three weeks ahead of severe weather in these areas during the typical severe-weather months of March through June. Although forecasting weeks in advance cannot pinpoint where individual tornadoes or hail storms will occur, they can forecast expected environmental conditions that are favorable for the formation of severe thunderstorms…read more.
