In Spanish it means “the little boy,” but this week El Nino is not playing kid’s games.”We will have the coldest weather of the season in this week,” said Ben Gelber, WCMH-TV meteorologist.Sub-zero wind chill factors and high winds are predicted until Thursday morning, Gelber said.Snowfall will vary from one to three inches throughout central Ohio, he said.The lowest temperature this winter was 13 F. This week, temperatures will plunge to 10 F and the wind chill factor will be 0 F to minus 20 F, he said.”We will experience at least four nights with temperatures below 20 F and at least three days with high temperatures below 30 F,” Gelber said. “It will not go above freezing until Friday.”El Nino, the warm pool of water in the eastern tropical Pacific which influences the jet stream, is responsible for the unseasonably warm winter and the blast of cold weather to come, he said.”The northern branch of the jet stream is merging with southern branch this week,” Gelber said. “This allows polar air to plunge south bringing us the coldest weather of the season.”Historically, El Nino has produced cold weather and snowfall in March and April, he said.The current El Nino pattern is the strongest of the century, therefore cold weather during the spring months can be expected, Gelber said.WBNS-TV meteorologist Chris Shumway said this week’s cold weather is not a result of El Nino.”This is a classic, old-fashioned winter storm,” Shumway said. “El Nino is always a factor, but we get storms like this anyway.”This week’s cold weather is a batch of dry arctic air, Shumway said.”We should be used to this type of weather but because of the mild winter, it will be a shock to the system,” he said.Students are at a higher risk of encountering stormy weather during spring break travel, Gelber said.”Unfortunately El Nino is showing no signs of backing off and the pattern will persist into spring,” he said.
