"Mother Nature is not quite sure what season we're in," Bayern said. "Expect temps to spike into the 80s and low 90s on Monday and Tuesday as a strong but brief ridge of high pressure builds and a push of easterly winds arrive."

The unseasonable temperatures are expected to drop back into the 70s on Wednesday as Poland could see as much as 0.25 inches of rain.
