Nighttime lows will be at or near freezing throughout the region, and moderate winds will be be from the north. Skies will be clear to partly cloudy.

Trajectory weather: Air mass trajectories from the Arbuckle Mountains move south over central Texas along moderate northerly winds. The trajectories move close to the ground showing little lift. Temperatures at the source area are low this morning and will reach the mid 40s in the afternoon in southern Oklahoma and mid 50s in central Texas. Skies will be clear to partly cloudy. Overnight temperatures will be be in the 20s.

OUTLOOK: *** Low Threat today and Low Threat tomorrow *** Poor conditions for pollen release today and poor conditions tomorrow. Poor conditions for entrainment and transport today. Skies will be clear to partly cloudy today with cool conditions. Temperatures at the source area this morning were below freezing and will only reach the mid 40s this afternoon, which is barely reaching the favorable range for pollen release. Conditions are poor for entrainment as trajectories travel near ground level. Tomorrow will see similar conditions in southern Oklahoma, still below the optimum for pollen release.

Trajectory Start (s) (shown by black star on map): Davis, OK.
