UNDATED (WNWN) - Why is it so darn cold and why won’t it go away. National Weather Service Meteorlogist Bob Dukesherer says we can blame strands of the Polar Vortex drawn down into the United States by a low pressure zone that arrived over the Great Lakes states on Tuesday. Technically, it’s a trough extension while the polar vortex itself remained in place over the North Pole. He says the same sort of thing happened earlier this month when temperatures went double digit sub-zero. He says it appears we may be stuck with this pattern, for the most part with the bitterly cold temperatures for the rest of this month. AccuWeather is forecasting a low of 14-below zero next Tuesday morning.
