Mountain Cedar Pollen Forecast

 

 

Date Issued: 12 January 2004

 

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Monday and Tuesday, Jan 12 and 13. TX/OK: Mild weather continues across the region for the next few days. Daytime highs will be in the upper 50s and 60s and night-time lows will be in the upper 30s to upper 40s. Skies will be partly to mostly cloudy as a weak low pressure system moves through the area bringing some chances of precipitation, especially in central Texas. Winds will be light and variable.

 

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the north over central Oklahoma then circle round the area then move east on light winds. The trajectories show less than ideal characteristics for entrainment and travel of pollen downwind.  Temperatures at the source will be mild, highs in the low 60s today and upper 50s tomorrow. Night-time low will be about 40 degrees. Skies will be cloudy and winds will be light. Trajectories on Tuesday move to the northeast and then east across eastern Oklahom and Arkansas.

 

OUTLOOK: *** Moderate Threat to High Treat *** Favorable conditions for pollen release. Temperatures are favorable for pollen release but humidities are running a little high and winds are light. Trajectories are not optimal for pollen entrainment and travel. Much of the pollen released from the Arbuckles is likely to remain local with only moderate conditions for downwind travel. High threat for pollen exposure at areas close to the source, moderate downwind. Conditions tomorrow are likely to be a repeat of today with temperatures just a bit lower.

 

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