Cold conditions with wintery precipitation will occur across Oklahoma today. Conditions will be poor for pollen
dissemination thus there is a low threat. Because of the poor conditions for release, little pollen is expected
and conditions for entrainment and travel will be a minor consideration Little pollen will be in the atmosphere
in the next couple of days.
