Mountain Cedar Pollen Forecast

 

Date Issued: 30 January 2006

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Monday and Tuesday, Jan 30 and 31. TX/OK: Mild temperatures continue across the region today. Skies will be clear to partly cloudy with moderate north to northwest winds. Daytime highs on Monday will be in the upper 50s in Oklahoma and the upper 60s to low 70s in Texas. Winds will shift back to southerly late tonight. Lows tonight will be in the 30s throughout the region. Tuesday will be 5 to 10 degrees warmer ranging from the mid 60s to the mid 70s with strong southerly winds returning. The air will be dry and we may see red flag fire watch in effect in spite of the rain this past weekend.

Trajectory weather: The air mass trajectories from the Edwards Plateau begin moving to the southwest then curve around to the northeast as southerly winds return to the region later today. The trajectories show mixed conditions for extrainment and travel. Conditions at the sources will be favorable for pollen release today and tomorrow. Trajectories on Tuesday are conducive to transport and initially travel to the north but then stall and turn over Oklahoma as the winds shift again on Wednesday.

OUTLOOK: *** High Threat *** Good conditions for pollen release today and tomorrow. Warm temperatures, sunny skies, and moderate to high winds are ideal conditions for pollen dispersal.

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