Mountain Cedar Pollen Forecast

 

Date Issued: 28 January 2006

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Sat and Sun, Jan 28 and 29. TX/OK: Scattered rain and thunderstorms on Saturday. Clearing will occur on Saturday afternoon from the west. Highs on Saturday in the low 60s in Oklahoma and the low 70s in Texas with moderate to strong and gusty southwest to westerly winds. Overnight lows from the upper 30s to mid 40s. Sunday will have clear to partly cloudy skies with daytime highs in the 60s in Oklahoma and the 70s in Texas. Winds will be moderate from the west shifting to northwest winds late on Sunday. Mild temperatures will continue on Monday but will be about 5 degrees cooler than Sunday.



Trajectory weather: The air mass trajectories from the eastern side of the Edwards Plateau Texas move to the northeast today. Those from the western side of the Plateau move to the east. Scattered areas of heavy rain on Saturday at the source areas along with high humidity will inhibit pollen release. Also the trajectories from the west show poor characteristics for entrainment and travel. Sunday’s trajectories begin moving east, southeast but shift around toward the north, northeast but show poor characteristics for pollen dispersal.


OUTLOOK: *** Low threat Saturday/ Moderate on Sunday *** Conditions are poor for pollen release today but better on Sunday; however, the trajectories on Sunday are not ideal for transport. Pollen released on Sunday may stay close to the mountain cedar population areas.

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