Mountain Cedar Pollen Forecast

 

 

Date Issued: 27 Dec 2003

 

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Friday, Saturday and Sunday, Dec 26 to 28. TX/OK: Mild weather continues but clouds move into the region bringing moist air and strong southerly winds ahead of a cold front that will move through the region this weekend. Friday will be partly to mostly cloudy throughout the region with strong southerly winds. Temperatures will be in the 60s to low 70s in Texas and 50s to 60 in Oklahoma. Nighttime temperatures will be mild, dropping only about 10 degrees. Saturday will be cloudy with rain chances increasing throughout the day. Thunderstorms are likely to occur. Southerly winds will continue with temperatures in the 60s in the north and 70s in the south. The cold front will push through the area late Saturday night into Sunday morning shifting winds to the northwest and bringing temperatures down about 10 degrees. Clearing skies will begin on Sunday decreasing the chance of precipitation during the day. Temperatures will range from mid 50s to mid 60s through the region..

 

Trajectory weather: Air mass trajectories move north from the Arbuckle Mountains and then northeast and show good lift characteristics this morning ahead of the cold front. At the source, temperatures are mild with strong southerly winds but humidity is high. Weather in Arbuckle Mountains will continue to be humid with chance of rain and thunderstorms during the day. After the frontal system passes through the area, temperatures will be 10 degrees cooler than Saturday and humidity will be low. Trajectories on Sunday will move east and then turn south into east Texas and Louisiana but conditions are not optimal for entrainment and travel

 

OUTLOOK: *** Moderate Risk  *** Mixed conditions for pollen release. High humidity and chance of showers will limit pollen release, but any pollen released will be carried to the north, northeast with the strong southerly winds. As clearing occurs on Sunday conditions may become favorable for pollen release in the afternoon but trajectories are not optimal for transport.

 

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