Mountain Cedar Pollen Forecast

 

Date Issued: 9 Jan 06

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Mon and Tues Jan 9 and 10. TX/OK: Strong frontal system moves into the region this morning bringing strong northerly winds to the entire region. Monday will see cooler temperatures and cloudy skies in Oklahoma with strong gusty north to northeast winds and a chance of light rain or light snow in parts of the area. Daytime highs in Oklahoma will be in the mid 40s to low 50s and nighttime lows in the 30s. Tuesday will bring clearing skies with moderate NW winds and high temperatures in the 40s. In Texas skies will be clear to partly cloudy with daytime highs in the upper 70s to low 80s on Monday. Nighttime lows will be in the upper 30s to low 40s. Winds will be from the south or southwest and shifting to the northwest as the frontal systems moves in late on Monday. On Tuesday winds will be from the NW with temperatures in the low to mid 60s. Southerly winds will return on Wednesday throughout the Oklahoma/Texas region.

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the south and then southeast over central and southeast Texas. The trajectories are associated with a cold sinking air mass and show poor characteristics for entrainment and travel. Trajectories on Tuesday begin moving to the southeast then turn late in the day to the north northeast.

OUTLOOK: *** Low to Moderate threat *** Conditions are marginal for release and transport today and tomorrow. Low morning temperatures may limit pollen release in the Arbuckle Mountains. Any pollen from the Arbuckles will stay in the area because the cold area mass moving in to the region is not conducive to pollen transport.

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