Mountain Cedar Pollen Forecast

 

Date Issued: 21 January 2006

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Sat and Sun, Jan 21 and 22. TX/OK: Yesterday’s cold front with continuing northeast winds result in near normal temperatures for the region on Saturday. Skies will be partly to mostly cloudy during the day on Saturday with temperatures in the 50s and light northeast winds. Rain will begin moving into the region late this evening and spread northward overnight bringing much needed precipitation to many parts of the region on Sunday. Lows tonight will range from the low 30s in Oklahoma to the mid 40s in Texas. Northerly winds, cloudy skies and rain possibilities will keep temperatures in the upper 40s to low 50s on Sunday. Precipitation will move east on Sunday and should leave partly cloudy skies on Monday with light north winds and daytime highs in the 50s.



Trajectory weather: The air mass trajectories from the Edwards Plateau Texas show movement to the west than circulation back south over central to western Texas. The trajectories show good characteristics for entrainment and travel. Conditions at source areas are fair with temperatures at the lower end of the range for pollen release. Sunday’s trajectories all move to the south but show poor characteristics for pollen entrainment and travel.


OUTLOOK: *** Moderate risk Saturday/Low risk Sunday *** Conditions are fair for pollen release today but less favorable on Sunday with the predicted rain.

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