Mountain Cedar Pollen Forecast

 

 

Date Issued: 31 Dec 2003

 

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Wednesday and Thursday, Dec 31 and Jan 1. TX/OK: Mild conditions continue through the region on Wednesday with temperatures in the 60s and moderate southerly winds. Gulf moisture begins moving in on the southerly winds replacing the cool dry air that had been in place. Clouds will increase during the afternoon and eveing as the next storm system approaches from the west. The system brings a good chance of rain throughout the region on Thursday along with a chance of thunderstorms. Overnight lows will be mild in the upper 40s in the north and upper 50s in the south. Highs tomorrow will continue mild in the 60s north to low 70s south with continuing southerly winds.

 

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the north, northeast over central and eastern Oklahoma on moderate to strong southerly winds. The trajectories show good characteristics for entrainment and travel of pollen downwind. Skies will partly cloudy across the region with mild temperatures in the 60s. Conditions at the source are mild but humidities are running high this morning. Mild conditions expected overnight.Trajectories tomorrow show movement to the northeast. Mild temperatures will continue tomorrow but skies will be cloudy with a chance of rain and thunderstorms throughout the region.

 

OUTLOOK: *** High Threat today/ Low to Moderate tomorrow *** Favorable conditions for pollen release today/ mixed condtions tomorrow. Although hunidities are running high this morning, temperatures are favorable for pollen release. Moderate southerly winds will carry pollen into Oklahoma City area with slighlty lower exposure in the Tulsa area. Higher humidities and chances of rain tomorrow will decrease the likelihood of significant pollen release. However if precipitation fails to materialize pollen release may occur and conditions are good for downwind travel.

 

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