Mountain Cedar Pollen Forecast

 

Date Issued: 28 January 2007

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Sun and Mon, Jan 28 and 29. TX/OK: Cool conditions across the region today and Monday. Daytime highs on Sunday will be in the mid to upper 30s in Oklahoma and the mid 40s to mid 50s in Texas. Skies will be clear to partly cloudy with moderate northerly or northeast winds. Winds will be shifting to southerly winds this evening or overnight. Lows tonight will range from the 20s to mid 30s. Temperatures on Monday will range from the mid 40s in Oklahoma to the mid 50s in Texas. Skies will be partly to mostly cloudy with moderate winds from the south. In Oklahoma winds will be shifting back to northerly on Monday afternoon.

Trajectory weather: The air mass trajectories from the Edwards Plateau Texas circle around central and west Texas reflecting the shifting winds today and tomorrow. The trajectories show mixed characteristics for entrainment and travel. Conditions at the source areas on the Plateau are cold this morning which will limit pollen release to the afternoon hours. Monday's trajectories again circle around central Texas and then move to the east. Trajectory characteristics continue to show poor to moderate characteristics for entrainment and travel. Conditions at the source areas will be cold again on Monday morning limiting pollen release to the afternoon hours.


OUTLOOK: *** Mixed conditions: Moderate to High threat *** Cold morning temperatures will limit pollen release to the afternoon hours. Overall only a moderate risk although pollen levels may still be high close to mountain cedar populations.

Trajectory Start (s) (shown by * on map): Austin, TX; Junction, TX; San Angelo, TX.
