Short-sleeves or parka? That's the dilemma each Thanksgiving.
The holiday occurs at the time of year when autumn is releasing the last vestiges of summer's warmth and embracing the chill of winter. As a result, the unpredictable is the norm.
“It's the clash of seasons,” said Jeremy Wesely, meteorologist with the National Weather Service in Hastings, Neb. “During this period of time you have huge swings in temperature.”
In 1983, the Omaha area shoveled out of 10 inches of snow that fell over the extended holiday weekend. Some years, though, skies have been sunny and temperatures have lingered in the mid-60s to near 70 degrees.
The battle of seasons is being driven by cold air that is building across the polar region and sinking south where it confronts warm air rising from the Gulf of Mexico.
“Weather is always about trying to create equilibrium on a global scale,” Wesely said.
