Mountain Cedar Pollen Forecast

 

Date Issued: 24 Dec 2006

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Sun and Mon, Dec 24 and 25. TX/OK: Partly to mostly cloudy skies over Oklahoma today with clearing moving from west later today. High temperatures will be in the mid to upper 40s with a chance of rain in southeastern Oklahoma near the Texas border. Light variable winds shifting to northwest winds this afternoon with a cold front moving in to the state. Tonight there is a chance of light rain or light snow flurries in parts of Oklahoma. In Texas, areas of light to moderate rain will continue through the afternoon moving out of the area this evening. Temperatures today will be in the mid to upper 40s with light winds, shifting to northwest winds as the cold front moves into the area. Overnight lows will range from the upper 20s to the upper 30s throughout the region. Monday will see partly cloudy skies with moderate to strong northwest winds and temperatures in the 40s in Oklahoma and 50s to low 60s in Texas.

 

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the south, southeast over south central Oklahoma and east Texas. The trajectories show moderate characteristics for entrainment and travel. Conditions at the Arbuckle Mountains are only marginal for pollen release. Trajectories on Monday move to the southeast but show poor characteristics for entrainment and travel with cold, sinking air. Conditions tomorrow will again be marginal for pollen release.

OUTLOOK: *** Low Threat *** Conditions are only marginal for pollen release. Some elevated pollen levels may occur close to the mountain cedar populations in the Arbuckle Mountains

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