Mountain Cedar Pollen Forecast

 

Date Issued: 9 January 2007

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Tues and Wed, Jan 9 and 10. TX/OK: Clear to partly cloudy skies with mild day time temperatures will continue over the next few days in the Oklahoma-Texas region. Day time highs today and tomorrow will be in the 50s in Oklahoma and the 60s in Texas. Winds today will be moderate to strong from the north in Oklahoma and east or northeast in Texas. Lows tonight will range from the upper 20s to 30s. Winds will be shifting to the southeast overnight. Wednesday will have moderate to strong south or southeast winds throughout the region and increasing clouds.

 

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the south this afternoon then circle back to the north over central Oklahoma tonight and continue north tomorrow. The trajectories show moderate characteristics for entrainment and travel. Trajectories on Wednesday move to the north over Oklahoma and then turn northeast over Kansas. Conditions at the source area are cold this morning and will be cold again tomorrow morning but will be in the favorable range by noontime on both days allowing for pollen release in the afternoon.


OUTLOOK: *** High threat *** Conditions are favorable for pollen release. Pollen concentrations will be greatest near the source areas. Central Oklahoma including Oklahoma City may see higher levels tomorrow. Long range transport of pollen from the Texas populations is possible tomorrow giving a moderate to high exposure risk for the whole state.

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