Mountain Cedar Pollen Forecast

 

Date Issued: 24 Dec 2005

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Sat and Sun, Dec 24 and 25. TX/OK: Strong frontal system moves into the region this morning bringing strong northwest winds to the entire region. Saturday will see cooler temperatures and cloudy skies in Oklahoma with strong gusty NW winds and light rain to parts of the area. Daytime highs will be in the 50s and nighttime lows in the 30s. Sunday will bring clearing skies with moderate NW winds and high temperatures in the 50s. In Texas skies will be clear to partly cloudy with daytime highs in the upper 60s to mid 70s. Nighttime lows will be in the upper 30s. On Saturday, winds will be strong and gusty from NW. Winds will be moderate and shift around to westerly on Sunday. Southerly winds will return on Monday throughout the Oklahoma/Texas region.


Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the southeast over eastern Oklahoma and northeast Texas. The trajectories are associated with a cold sinking air and show poor characteristics for entrainment and travel. Trajectories on Sunday begin moving to the southeast then turn late in the day to northeast and then east. If Arbuckle populations are releasing pollen, we may see some in northeast Oklahoma late Sunday and Monday.


OUTLOOK: *** Low threat *** Conditions are marginal for pollen release today and better on Sunday; however, the severe drought throughout the region has delayed the pollen season. At this time we do not have confirmation that the trees have started to pollinate.

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