Mountain Cedar Pollen Forecast

 

Date Issued: 07 December 2002

Mountain Cedar location(s): Arbuckle Mountains, OK

Regional weather: Saturday, December 7 TX/OK/AR: Sunny to partly cloudy conditions will continue today as high pressure to the east influences the regional weather picture. Throughout the region temperatures will be warming with light winds from the southwest to west.  Temperatures will moderate today with 50s throughout the Texas region and low 50s north in Oklahoma.  During the night cloudy to partly cloudy conditions will prevail with temperatures just above freezing north and in the mid to upper 40s south. Beginning Sunday the high pressure will shift further east and pacific moisture will begin to move in from the west.  Increasing chance of rain will occur to the south and southwest beginning by mid-afternoon with rain by early evening across the southern edge of the Edwards Plateau. Winds will shift from predominantly south to southwest over to a north to northeast direction.      

Trajectory weather:  The air mass trajectories from the Arbuckle Mountains move to the northeast over the Tulsa area then turn towards the south-southwest as the next front approaches. Light winds today from the southwest will turn out of the north overnight.  Temperatures will be in the upper 40s to mid 50’s today, in the lower 40s overnight and will stay there during Sunday.  Skies will be clear this afternoon to partly cloudy throughout the period and humidity will remain high.  Sunday night into Monday will see an increasing chance of a few showers to the south.   

OUTLOOK: ***Low threat today *** favorable conditions for pollen release today unfavorable on Sunday. Conditions in southern Oklahoma will be just in the favorable range although humidities mains high today but unfavorable as the moisture moves in on Sunday.  However our informants have yet to observe active pollination within any of the populations in the region. Therefore, there is a low threat for significant pollen release in the area

Trajectory Start(s) (shown by blackstar on map):Sulfur, Oklahoma
