A lot of people are sniffling and coughing right now, but not necessarily from cold or flu.
A warm weekend saw pollen counts for mountain cedar soar to high levels. Unlike most other spring allergens, cedar pollinates during the winter months.
Allergists say it needs just one day of warmth to start a cycle of misery.
That day, according to pollen counts in North Texas, was Sunday.
"So on a nice day where everybody wants to go out and go running and enjoy the nice weather for a break in the cold, that's when the mountain cedar is actually highest. It's that cedar that causes the problems with allergies that people are experiencing right now," said Texas Health Dallas allergist Dr. Gary Gross.
Until the cold returns, mountain cedar will continue to pollinate.
