Mountain Cedar Pollen Forecast

 

Date Issued: 18 January 2006

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Wednesday and Thuirsday, Jan 18 and 19. TX/OK: Warm temperatures and strong southerly winds return to the area on Wednesday and Thursday. Skies will be clear to partly cloud and high daytime temperatures will range from the mid-60s to the low 70s across the region. Air is extremely dry and a red flag fire watch is in effect in many counties throughout the region. Overnight lows will range from the upper 30s to the mid-40s. Warm, dry, windy coniditions will continue on Thursday with temperatures a few degrees warmer than today. Next frontal system will move through the area on Friday bringing a chance of precipitation to the area.

Trajectory weather: The air mass trajectories from eastern Texas move to the northeast over Oklahoma and Missouri and show good characteristics for pollen entrainment and travel. Trajectories from the western side of the Edwards Plateau initially move to the northeast then turn back south under the influence of the next frontal system, the trajectory show mixed characteristics for pollen transport with those at lower elevations sinking and moving along ground level. Thursday's trajectories show similar patterns. Parlty cloudy skies, warm temperatures and gusty winds will occur at the source areas today and tomorrow.

OUTLOOK: *** High Risk *** Favorable conditions for pollen release today and tomorrow. Trajectory characteristics are conducive to pollen entrainment and transport from the eastern side of the Plateau. Trajectories from the western side of the Plateau show mixed characteristics for pollen transport.

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