Date Issued: 16 January 2008


Mountain Cedar Location(s): Arbuckle Mountains, OK


Regional Weather: Wednesday, Jan 16. TX/OK: A cold front will move across the southern plains and Texas today and into Thursday. Temperatures today will be in the mid to upper 40s in Oklahoma but dropping as the front moves through the area. Skies will be cloudy and winds from the south, southeast shifting to the northwest as the front moves through the state. Chances of rain increase in the afternoon and evening possibly changing to snow or light freezing rain. Highs in Texas will range from the low 50s in the north to the low 60s in the south. Skies will be partly to mostly cloudy throughout the state with winds light to moderate from the south but shifting to northwest tonight. Temperatures on Thursday will be much colder throughout the region.


Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the east and northeast over eastern Oklahoma on moderate winds. The trajectories show moderate characteristics for entrainment and travel of pollen downwind. Partly to cloudy skies and seasonal temperatures will prevail across the region but high humidity will occur at the source site today making conditions only moderately favorable for pollen release.


OUTLOOK: *** Low to Moderate Threat today *** Conditions only moderately favorable conditions for pollen release. Temperatures will just reach the favorable range in the Arbuckle Mountains with high humidity. The resulting conditions are only moderately favorable.


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