OUTLOOK: *** Low Threat *** Early in the season, though a few cones may be ready to release pollen. Humidities will be favorable by midday. Temperatures will become favorable during the afternoon but will not creep very far into the favorable range (only low 50's near the source region). Some light amounts of pollen may be released. Any effects on the populace should be minimal, though some residents of south-central OK and/or north-central TX may be affected by today's release. On Saturday.... conditions will be unfavorable for pollen release. Humidities will be higher and temperatures near the source region will likely top out in the upper 40's. The trajectory moves slowly to the north. Low Risk on Saturday for residents of central OK (and elsewhere), including Oklahome City. TK
