Mountain Cedar Pollen Forecast


Date Issued: 10 January 1998

Mountain Cedar location(s): Edwards Plateau, Texas

Regional weather: Sunday, January 10 - TX/OK: Partly cloudy to sunny today with high pressure in control. A few morning clouds eastern OK. Highs in the 40's OK....mostly 50's and 60's TX. Lows tonight in the 20's and 30's.

Trajectory weather: Sunny and warm with a high in the 60's. Clear tonight, low in the low 30's. Mostly sunny on Monday, high in the upper 50's OK. Becoming mostly cloudy late afternoon for the Austin trajectory, high near 50.

Trajectory confidence: High

OUTLOOK: *** SERIOUS Threat *** Conditions are very good for pollen release across the Plateau. Temperatures and humidities are in the favorable ranges and winds are moderate. Significant release expected today. Slow movement of airborne pollen during the next 24 hours suggests that residents of central and northern Texas will feel the most ill effects from today's release. This includes the towns of San Angelo and Abilene....eastward to Wichita Falls, Dallas, Ft. Worth, and Waco. By Monday morning, airborne pollen will be moving through southern and eastern Oklahoma and will continue to the northeast. People living in Ada, Oklahoma City, McAlester, Tulsa, and nearby areas are most likely to be influenced on Monday. Residents of Springfield and Joplin, MO, will have pollen moving through their region by Monday evening. It's possible for pollen to continue northeast across Missouri Monday night, though the potential for wet weather will play a large part in how much pollen remains airborne after Monday evening. Some washout appears likely. TK
