Mountain Cedar Pollen Forecast

 

Date Issued: 18 Jan 06

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Wednesday and Thuirsday, Jan 18 and 19. TX/OK: Warm temperatures and strong southerly winds return to the area on Wednesday and Thursday. Skies will be clear to partly cloud and high daytime temperatures will range from the mid-60s to the low 70s across the region. Air is extremely dry and a red flag fire watch is in effect in many counties throughout the region. Overnight lows will range from the upper 30s to the mid-40s. Warm, dry, windy coniditions will continue on Thursday with temperatures a few degrees warmer than today. Next frontal system will move through the area on Friday bringing a chance of precipitation to the area.

 

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the northeast over northeast Oklahoma and Missouri on strong southerly winds. The trajectories show good characteristics for entrainment and travel of pollen downwind. Parlty cloudy skies, warm temperatures and gusty winds will occur at the source site today. Thursdays trajectories show mixed characteristics for transport under the influence of the next frontal system moving into the area.

OUTLOOK: *** High risk today/Moderate Thursday *** Favorable conditions for pollen release today and tomorrow. Trajectory characteristics are conducive to pollen entrainment and transport on Wednesday. Characteristics are less favorable for transport on Thursday limiting downwind exposure.

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