Date Issued: 28 Dec 2006


Mountain Cedar Location(s): Arbuckle Mountains, OK


Regional Weather: Thursday and Friday, Dec 28 and 29. TX/OK: Partly to mostly cloudy skies and mild temperatures and southeast winds throughout the region today and tomorrow. Day time highs Thursday and Friday will be in the 50s in Oklahoma and 60s in Texas. Night time lows will stay mild with the cold cover dropping into the low to mid 50s. Chances of rain will be increasing through Friday. Scattered showers and thunderstorms are likely on Friday throughout the region with significant accumulation possible in some areas.

 

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the northwest over central and western Oklahoma with strong southeast winds. The trajectories show good characteristics for entrainment and travel of pollen. Conditions at the source are mild and significant pollen release is possible. Friday's trajectories continue to move to the northwest. Rain is likely at the source areas in the Arbuckle Mountains tomorrow thereby reducing the chances of pollen release; however, pollen release may occur in areas without rain.



OUTLOOK: *** High Threat today/Low to Moderate on Friday *** Favorable conditions for pollen release today/mostly unfavorable tomorrow. Significant pollen release likely today. Rain and thunderstorms are possible tomorrow throughout the region resulting in a low threat. As always, pollen release is possible tomorrow in areas without rainfall.


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