Trajectory confidence: High.

OUTLOOK: *** Low Threat *** unfavorable conditions for pollen release today. In most areas of the Plateau temperatures should reach the tolerance range but precipitation and humidity will remain high. However, informants on the plateau suggest that the cones have yet to ripen, therefore pollen release has not yet begun. Residents throughout south-central TX or the hill country should have another day without any ill effects.
