Mountain Cedar Pollen Forecast

 

Date Issued: 7 January 2007

Mountain Cedar Location(s): Edwards Plateau, Texas

Regional Weather: Sun and Mon, Jan 7 and 8. TX/OK: Clear to partly cloudy skies with mild day time temperatures and cool nights will be in place over the next few days in the Oklahoma-Texas region. Day time highs today in Oklahoma will range from the upper 40s to mid 50s and from the mid 50s to upper 60s in Texas. Winds today will be moderate to strong and gusty from the northwest. Lows tonight will range from the 20s to low 30s. Highs on Monday will be in the mid 50s in Oklahoma and the 60s in Texas. The area will be less windy on Monday with moderate west or southwest winds.

Trajectory weather: The air mass trajectories from the Edwards Plateau Texas move to the south, southeast. The trajectories show poor to moderate characteristics for entrainment and travel. Conditions at the some of the source areas on the Plateau are cold this morning but will warm quickly into the favorable range. Monday’s trajectories move to the east, northeast but begin circling to the south and southwest on Tuesday. Trajectory characteristics show poor to moderate characteristics for entrainment and travel. Conditions at the source areas will be cold again on Monday morning limiting pollen release to the afternoon hours.

OUTLOOK: *** High threat *** Conditions will be favorable for pollen release Sunday and Monday; however, trajectories are not ideal for pollen entrainment and travel. Therefore most of the pollen will remain close to source areas on the Plateau. The Dallas-Fort Worth area may pick up some pollen from the population in the Arbuckle Mountains in Oklahoma.

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