Mountain Cedar Pollen Forecast

 

Date Issued: 13 January 2007

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Sat and Sun, Jan 13 and 14. TX/OK: A major winter storm and arctic cold front moving across the region this weekend. Freezing rain and sleet will occur in Oklahoma and north Texas with highs in the 20s and moderate north winds today and Sunday. The front will slowly push through central Texas dropping temperatures. Heavy rains are possible in central Texas with winds shifting to northerly during the morning and afternoon today.

Trajectory weather: The air mass trajectories from Edwards Plateau Texas move to the southwest and then curve to the northeast. The trajectories show mixed characteristics for entrainment and travel. Conditions at the source areas on the Plateau are mostly unfavorable for pollen release. Favorable temperatures only along the southern edge of the Plateau and San Antonio but rain in this area will limit pollen release. Sunday's trajectories show movement around southwest Texas. Conditions at the source areas will again be unfavorable for pollen release on Sunday.


OUTLOOK: *** Low threat *** Conditions are unfavorable for pollen release today and Sunday.

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