TULS, Okla. — We have yet to have truly Arctic air head to Oklahoma yet this season.
Arctic air is defined as the usually frigid, dense air mass that forms around and north of the Arctic Circle.
When the jet stream buckles southward, it allows an open door for that cold, dense air to surge southward and cause well below-normal temperatures wherever it goes.
It tends to warm up on its journey southward due to increasing daylight, but can stay colder if it travels over a big snowpack.
We are in line to get at least a glancing blow of Arctic air early next week, with a reinforcing Arctic cold front later in the week possible.
Below-average temperatures are usually guaranteed when this air arrives, but wintry precipitation is not, especially given how dry the air often is.
