Mountain Cedar Pollen Forecast

 

Date Issued: 26 January 2005

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Wednesday and Thursday, Jan 26 and 27. TX/OK: Another Canadian air mass will move through the region today bringing somewhat cooler temperatures for the next few days.Temperatures on Wednesday will be in the 50s and low 60s in Oklahoma and the upper 60s and 70s in Texas. Skies will be partly to mostly cloudy. In Oklahoma winds will be from the North today and in Texas winds will gradually shift to northerly. Overnight lows will be in the 30s and 40s. On Thursday highs will be in the 40s in Oklahoma and the 50s in Texas. Winds will be from the northeast and shifting to the east. Skies will be mostly cloudy with possiblity of scattered showers in Texas.

Trajectory weather: The air mass trajectories from Edwards Plateau show movement to the southwest and west and then turn back north. Conditions at the source will be cloudy and warm. The trees are past the peak of the pollen release season; however, significant release may occur in some areas. On Thursday trajectories show movement to the west, northwest and then to the north. Temperatures will be in the 50s with scattered showers across the Plateau.

OUTLOOK: *** Moderate to High Threat Wednesday/Low to Moderate Threat Thursday *** Good conditions for pollen release on Wednesday, mixed on Thursday.  Partly cloudy skies, moderate winds and warm temperatures make for good conditions for pollen release. Although the trees are past the peak release period, significant amounts of pollen may become airborne especially close to the source populations. Thursday will be cooler with scattered showers likely across the region reducing the chance of significant pollen release.

Trajectory Start (s) (shown by * on map): Austin, TX; Junction, TX; San Angelo, TX.
