Date Issued: 21 Jan 06


Mountain Cedar Location(s): Arbuckle Mountains, OK


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 move from the Arbuckle Mountains to the southwest over southwest Oklahoma and west Texas. The trajectories show good characteristics for entrainment and travel. Conditions at the source today are marginal with low morning temperatures. Trajectories on Sunday move to the south over central Texas but show poor characteristics for pollen entrainment and travel.


OUTLOOK: ***
Low threat ***
Conditions are marginal for pollen release today and less favorable on Sunday. Any pollen released will move away from major population centers of Oklahoma.


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