Mountain Cedar Pollen Forecast


Date Issued: 20 January 1998

Mountain Cedar location(s): Arbuckle Mountains, OK

Regional weather: Wednesday, January 20 - TX/OK: Weak frontal system in the region, a precursor of a larger system that will more fully develop during the next day or so. Dry today, but a chance of showers tonight and Thursday for areas of OK. Morning clouds and fog are a big problem in parts of Texas, mostly south-central. Otherwise.....partly cloudy to sunny and very warm with highs today in the 60's OK, 70's and 80's TX. Lows tonight mostly in the 40's and 50's.

Trajectory weather: Mostly sunny today, high in the upper 60's. Partly cloudy tonight with a chance of scattered showers after midnight, low in the low 40's. Cloudy with a chance of rain on Thursday, high in the low 50's.

Trajectory confidence: High

OUTLOOK: *** SERIOUS Threat *** Conditions are quite favorable for pollen release. Significant release expected today. Airborne pollen from this source will be moving through Oklahoma City this afternoon....Tulsa early tonight....and into southwest MIssouri after midnight. Washout of airborne pollen will become increasingly likely after midnight. Residents of Missouri should be much less affected than those in Oklahoma. TK
