Date Issued: 26 January 1999
Mountain Cedar location(s): Edwards Plateau, Texas
Regional weather: Tuesday, January 26 - TX/OK: Low pressure system to the north will drag a cold front into the region tonight. Some clouds are moving into western sections and there's some low clouds in parts of south TX this morning. Most areas are clear to partly cloudy. Windy and warm ahead of the front today with highs mostly in the 60's and 70's.....a few 80's south TX. Lows tonight ranging from the upper 20's far northwest to 50's southern and eastern sections.
Trajectory weather: Austin: Partly cloudy and windy with a high in the 70's today. Partly cloudy tonight, low in the 40's. Variably to mostly cloudy on Wednesday, high near 50. Junction/San Angelo: Partly cloudy today and tonight. High in the 70's, low in the low 40's. Variably cloudy with a slight chance of showers on Wednesday, high in the upper 50's.
Trajectory confidence: High
OUTLOOK: *** Moderate Threat *** Now that we are nearing the end of the season, decreasing amounts of airborne pollen are expected. Mostly favorable conditions for pollen release, especially from the west. As on other occasions, airborne pollen from eastern sections of the Plateau will get caught up in winds ahead of the low pressure system and has the potential to travel very long distances. Pollen released from western sections of the Plateau will move slower after the first 12 hours as the winds weaken and eventually change direction. Pollen will be moving through central and northern Texas this afternoon and all but southeast Oklahoma tonight. Appreciable amounts of airborne pollen will continue through central and northeast Missouri after midnight......through northern Illinois and northern Indiana Wednesday morning....and into southern Michigan and northern Ohio Wednesday afternoon. The rest of the airborne pollen will affect resisdents of southeast Kansas and northeast Oklahoma on Wednesday. TK
