Mountain Cedar Pollen Forecast

 

Date Issued: 23 January 2006

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Monday and Tuesday, Jan 23 and 24. TX/OK: For the next two days the region should see clear to partly cloundy skies, light northerly winds and mild temperatures. Patchy fog in Oklahoma should burn off by noon on Monday leaving temperatures ranging from the low 50s in northern Oklahoma to the low 60s in south Texas. Overnight lows will be in the 30s throughout the region. Light winds and partly cloudy skies will continue on Tuesday with temperatures in the 60s.

Trajectory weather: The air mass trajectories from the Edwards Plateau move to the southwest then circle around to the west and then northwest.  The trajectories show mixed characteristics for pollen transport. Conditions at the sources will be cool this morning but will be favorable in the afternoon. Low temperatures again tonight might limit monring pollen release on Tuesday.Tuesday's trajectories move initially to the west then northwest over west Texas.

OUTLOOK: *** Moderate to high risk *** Good conditions for pollen release this afternoon after low morning temperatures. The trajectory characteristics show mixed conditions leading to entrainment and travel downwind. 

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