OUTLOOK: *** Low Threat *** Mixed conditions for pollen release. Temperatures and relative humidities will be in the favorable ranges during the afternoon hours. However, few cones are ready to release pollen this early in the pollen season. Any airborne pollen will tend to flow to western sections of Texas from this source region. Overall....Low Risk of pollen transport at this time. TK
