Conditions will be good for pollen dispersal today and tomorrow. However, there
will continue to be a moist atmosphere over Texas and some isolated showers may
occur, especially in and around the communities along the I-35 corridor. Entrainment and downwind travel will be
restricted with the atmosphere being stable keeping any entrained pollen
flowing near the ground where it can be removed. High temperatures will remain relatively
stable over the next two days with areas in the 50s today rising just to the
60s in the southwestern most communities.
