OUTLOOK: *** Serious Threat *** Conditions are favorable for pollen release today. Temperatures and humidities are favorable much of the day. Pollen released from this area may be carried long distances in the winds ahead of the low pressure trough. Airborne pollen will be moving through central and northeast OK today, including the cities of Oklahoma City and Tulsa...... through far southeast KS, central MO, and southern IL overnight.... continuing through southern sections of IN and OH on Thursday. Those persons living closest to the source in Oklahoma are most likely to feel any ill effects from today's release. TK
