Date Issued: 5 January 1998
Mountain Cedar location(s): Edwards Plateau, Texas
Regional weather: Tuesday, January 5 - TX/OK: Partly to mostly cloudy and warmer today in TX....mostly cloudy in OK as a weak system moves through the state. Highs in the 50's and 60's with some 40's northeast OK. Lows in the 20's and 30's, with some 40's south TX.
Trajectory weather: Austin: Variably cloudy today, high in the low 60's. Partly cloudy tonight, low in the mid-20's. Cloudy on Wednesday with a chance of rain in the afternoon, high in the low 40's. Junction/San Angelo: Mostly sunny today, high in the 60's. Fair tonight, low in the upper 30's. Mostly sunny Wednesday, high in the 60's.
Trajectory confidence: High
OUTLOOK: *** SERIOUS Threat *** Conditions quite favorable for pollen release. Winds are moderate to strong today with significant release expected. It appears that pollen released from the eastern side of the Plateau may travel long distances in the winds ahead of a weak disturbance. Residents of central and northern Texas and far south Oklahoma will feel the effects of today's release during the next 24 to 36 hours. In addition.....people living in southern and eastern Oklahoma and near the Missouri/Arkansas border will have airborne pollen moving through their areas tonight and Wednesday. Affected cities include Waco and Dallas/Ft. Worth, TX this afternoon.....Ada, McAlester, and Tulsa, OK overnight......and Springfield, MO Wednesday morning. Precipitation will probably wash out most airborne pollen during Wednesday afternoon. TK
