Mountain Cedar Pollen Forecast

 

Date Issued: 1 January 2007

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Mon and Tues, Jan 1 and 2. TX/OK: Clear to partly cloudy skies with seasonable day time temperatures and cool nights will be in place today and Tuesday in the region. Day time highs will range from the upper 40s to low 60s and night time lows from the mid 20s to low 30s. Winds today will be moderate and from the north in Oklahoma. In Texas winds will be from the north in central Texas and east, northeast in west Texas. Highs on Tuesday will be in the low to mid 50s with light variable winds. Winds in Oklahoma will be shifting tomorrow initially from the northeast in the morning and shifting to south, southwest winds in the afternoon. In Texas winds tomorrow will be from the east, northeast.

Trajectory weather: The air mass trajectories from the eastern side of the Edwards Plateau Texas move to the south and then curve to the west. Trajectories from the western side of the Plateau move to the west and then turn to the northwest tomorrow. The trajectories show moderate characteristics for entrainment and travel. Conditions at the source areas on the Plateau are cold this morning which will limit pollen release to the afternoon hours. Tuesday's trajectories move to the southwest (from the eastern side of the Plateau) or west (from western side of the Plateau). All the trajectories begin circling to the northwest and north later on Tuesday. Trajectory characteristics continue to show moderate characteristics for entrainment and travel. Conditions at the source areas will be cold again on Tuesday morning limiting pollen release to the afternoon hours.

OUTLOOK: *** Moderate to High threat *** Cold morning temperatures will limit pollen release to the afternoon hours. However we are near the season peak period so there may be significant amounts of pollen available for dispersal.

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