Metropolitan Area

Exposure Risk

Oklahoma City

Moderate to High Threat


Moderate to High Threat

St. Louis MO

Low to Moderate


Date Issued: 29 Dec 2004

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Wednesday and Thursday, Dec 29 and 30. TX/OK: Mild temperatures continue throughout the region for the next few days. Skies will be partly to mostly cloudy and chances of rain increase later this week. Patchy fog and mist over eastern regions of the Edwards Plateau should lift this afternoon. Daytime highs both Wednesday and Thursday from the mid to upper 60s in the north to low 70s in the south. Lows tonight will be in the 50s. Southerly winds will be moderate with gusts throughout the region.


Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the north, northeast. In additions trajectories show that the air masses from Texas will cross Oklahoma for the next two days. The trajectories from the Arbuckles show fair characteristics for entrainment and travel of pollen downwind. Temperatures in the Arbuckles will be in the 60s with partly cloudy skies on Wednesday. Condition will allow for pollen release this afternoon. Overnight temperatures will be in the 50s tonight with warming tomorrow into the mid 60s in the Arbuckles; again these are favoarble conditions for pollen release.

OUTLOOK: *** Moderate to High Threat *** Favorable conditions for pollen release in the Arbuckle Mountains. In addition trajectories from Texas especially the eastern side of the Plateau may bring additional pollen to the area.

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