Oklahoma Braces For November Arctic Blast

Temperatures may top 70 degrees on Sunday and Monday, but arctic air is expected to blow through Green Country over the next week due to effects from a major typhoon in the eastern Pacific.

WARN Team meteorologist Mike Grogan wrote in his weather blog that the power of that system is causing the jet stream to buckle northward in advance of it, pushing warmer air poleward.

“The frigid air at the Arctic then has to go somewhere so the jet stream reacts by buckling equatorward downstream,” Grogan said. “It just so happens that the dip in the jet stream will be right over the eastern U.S., acting to pull that Arctic air over much of the United States.”

The cold front will arrive Monday night with a biting north wind and our temperatures will cower below 50 degrees for the rest of the week, Grogan said.

Midweek, temperatures could be brought down to nearly 25 degrees below normal. Thursday temperatures may not reach 40 degrees, Grogan said.

“While the cold air through next weekend is a virtual guarantee, the prospects for a wintry mix are far less certain,” he said.
