Regional Weather: Tuesday, January 21 TX/OK/AR: Conditions will again be warm today in southern Texas but a front carrying much cooler
air will push into the northern regions. In northern Texas temperatures will drop by 7 to 10 degrees today with moderate winds

OUTLOOK: *** Low Threat Today*** Unfavorable Conditions for Pollen Release. Cloudy skies, moderate humidity levels and cold temperatures with high readings in the mid 30s result in unfavorable conditions for pollen release today. In addition, the trajectories show poor characteristics for pollen entrainment and travel downwind. The trees are nearing the end of the pollination season and the amount of pollen left to be dispersed is unknown at the time, but because of the conditions no pollen dispersal is expected. Similar conditions are expected tomorrow.
