Having been born and raised in Columbus, I’m used to it being cold November thru May.
However, I know it’s not common for the temperatures to be so low for so long.
Yahoo says the uncommonly cold weather is part of a weather pattern that started last year. This is when a system of cold air around the Artctic, aka a polar vortex, began pushing cold air into the North America.
The pattern continued sporadically throughout the summer. This is why we had cooler temperatures in the June thru late September last year.
Because of air flow in the middle and upper levels of the atmosphere that travel from northwest to southeast according to Bob Oravec of the National Weather Service.
“They form at different times of the year, and they tend to go farther south during the winter,” Oravec said. “Right now, we have that favorable weather pattern — a northwest flow from Alaska across a big part of Canada into the United States.”
He called it one of the more persistently cold winters in the United States. “Especially this month, the temperature anomalies are way below average across a big part of the central to eastern United States,” Oravec said.
