Mountain Cedar Pollen Forecast

 

 

Date Issued: 21 January 2009

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Wednesday, January 21 – TX/OK: Across the region warm sunny conditions will remain again today with temperatures warming from yesterday. In Oklahoma, temperatures will be in the 60s.  Winds will be moderate and from the west during the day, then shifting to light and variable overnight. Tonight temperatures will be in the mid 30s with clear skies then mostly sunny again tomorrow with temperatures in the 70s.  Winds will be moderate and from the south.  Tomorrow night skies will become partly cloudy with temperatures in the lower 40s and winds shifting from the east at about 10.  In Texas today’s temperatures will warm into the mid 70s across the region. Winds will be from the southwest and will be light in the morning, gaining to moderate this afternoon. Tonight temperatures will range from the upper 30s to the lower 40s.  Winds will be light to moderate and from the south and southwest.  Thursday skies will remain clear and sunny in the surrounding communities, with partly cloudy skies over the Plateau.  High temperatures will be in the mid to upper 70s and moderate winds from the south and southwest.

 

Trajectory weather: Air mass trajectories from the Arbuckle Mountain move to the east during the afternoon and then move north as southerly winds take over. Clear skies with warm conditions will occur today at the source area.  Winds will be light to moderate from the west. Conditions in the tree population in the Arbuckle Mountains will be good for pollen release today and tomorrow because of warm sunny conditions and moderate winds.  However, the stable atmospheric conditions will result in only moderate conditions for travel of pollen entrained in the atmosphere.

 

OUTLOOK: *** High Threat*** favorable conditions for pollen release along with moderate conditions for entrainment and transport. Warm conditions with moderate winds will present favorable conditions for pollen release, and moderate conditions for entrainment and travel.  Winds today will be initially from the west then from the south tonight and tomorrow.  However, stable air masses across the region may partially restrict the movement of pollen long distances from the source.  Sunny skies and dry conditions will maintain the chance of pollen dispersal and movement tomorrow.
