La Nina to bring colder, drier winter

Reading Time: 2 minutes MarketsFarm — There’s a La Nina poised to exert influence on the coming North American winter, according to Drew Lerner, senior agricultural meteorologist for World Weather Inc. in Kansas. A La Nina generates colder-than-normal temperatures, as opposed to the warm temperatures garnered from an El Nino. Both weather phenomenon can be found over the Pacific […] Read more
