Mountain Cedar Pollen Forecast

 

Date Issued: 27 January 2009

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Tuesday, January 27 – TX/OK: Across the region the weather will be affected by cold air and precipitation from the north today and tomorrow. In Oklahoma, high temperatures will be in the 20s today. Freezing rain and sleet will continue through most of the state with moderate to strong northerly winds. Overnight lows will be in the teens and high temperatures in the 30s tomorrow. Tomorrow winds will decrease and switch first from the west and then tomorrow night from the south. In Texas, temperatures will range from upper 20 and low 30s in the north after the cold front passes to the 70s in south ahead of the front. The cold front will continue to move south today. As the cold weather moves in, light rain will turn to light freezing rain throughout the region. Tonight temperatures will be in the mid to low 30s on the Plateau and in the mid to upper 30s in the surrounding communities. Winds will be moderate to strong from the north today and tomorrow. Tomorrow night, winds will begin to turn from the northeast in the surrounding areas and from the southwest along the western portion of the Edwards Plateau.

Trajectory weather: Air mass trajectories from the Arbuckle Mountain move to the south today under the influence of the strong northerly winds associated with the cold front. Rain, freezing rain, and sleet will occur today at the source areas in southern Oklahoma. Conditions in the tree population in the Arbuckle Mountains will be unfavorable for pollen release.

OUTLOOK: *** Low Threat *** poor conditions for pollen release along with poor conditions for entrainment and transport. Cold conditions and precipitation present poor conditions for pollen release, and poor conditions for entrainment and travel.

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