Mountain Cedar Pollen Forecast

 

Date Issued: 13 January 2006

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Friday and Saturday, Jan 13 and 14. TX/OK: Somewhat cooler (although still above normal) temperatures across the region today in the wake of the cold front that moved across the region Thursday. Skies will be mostly clear with strong to gusty northwest winds. Daytime highs on Friday will be in the 50s in Oklahoma and the 60s in Texas. Winds will decrease this evening and overnight lows will be in the 20s and 30s. Southerly winds will return on Saturday with temperatures in the 60s throughout the region and clear to partly cloudy skies.

Trajectory weather: The air mass trajectories from the Edwards Plateau move to the south then turn back north with the return of southerly winds late tonight and tomorrow. Although temperatures are mild across the Plateau and are favorable for pollen release, the trajectories show poor characteristics for entrainment and travel. Trajectories on Saturday all move to the north, northeast with good conditions that are conducive to transport.

OUTLOOK: *** High to Very High Risk *** Good conditions for pollen release for the next few days. Sunny skies with dry windy conditions. However, on Friday trajectories show poor conditions for transport so pollen will remain close to populations of mountain cedar trees. Conditions for long distance transport of pollen improve on Saturday.  

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