OUTLOOK: *** Low threat today; Low threat tomorrow *** Low conditions for pollen release today and Low conditions
tomorrow; Low conditions for entrainment and transport today, Low conditions tomorrow. 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.
