Regional Weather: Wednesday and Thursday, Jan 25 and 26. TX/OK: Warm, mild conditions to continue in Oklahoma and Texas over the next couple of days. Temperatures on Wednesday will be in the 60s to low 70s throughout the region with partly to mostly cloudy skies and light variable winds graduately shifting to southerly.

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the northwest then curve back to north, northeast over central Oklahoma and Kansas. The trajectories show good characteristics for entrainment and travel of pollen downwind. Partly to mostly skies will prevail across the region with warm temperatures at the source area. Mild conditions continue tomorrow although daytime highs will be a few degrees cooler than today. Trajectories on Thursday move to the north over central Oklahoma and eastern Kansas and then shift northeast.Characteristics are good for downwind dispersal.

OUTLOOK: *** Moderate to high risk today *** Favorable conditions for pollen release continue today and tomorrow. Trajectories characteristics are favorable for downwind dispersal.
