Mountain Cedar Pollen Forecast

 

Date Issued: 5 Jan 2005

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Wednesday and Thursday, Jan 5 and 6. TX/OK: A frontal system stretches across Oklahoma with day time highs in the upper 20s and 30s on Wednesday with moderate northwest winds. Rain, freezing rain, and sleet across the state on Wednesday. Precipitation should move out of the area later today. Nightime lows in the single digits and teens. On Thursday day time highs will be in the upper 20s and low 30s with partly cloudy skies and northerly winds.. The frontal system will move into Texas today dropping temperatures from the 60s and 70s on Wednesday to the 40s on Thursday. Rain and thunderstorms possible on Wednesday and partly to mostly cloudy skies on Thursday. Winds variable on Wednesday and from the north on Thursday.

 

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the south over eastern  Texas on strong northerly winds. The trajectories show poor characteristics for entrainment and travel of pollen downwind as cold air drains into the area.  Cold sinking atmospheric conditions results in the air-masses moving along the ground where any entrained particles are quickly filtered.  Rain, freezing rain, and sleet at the source today and party cloudy skies tomorrow. High temperatures in the 30s both days.

OUTLOOK: *** Low Threat today *** unfavorable conditions for pollen release. Rain and low temperatures will inhibit pollen release.  In addition, poor atmospheric conditions exist for pollen entrainment and travel with cold heavy air moving across the region at ground level. 

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