Date Issued: 24 December 1999
Mountain Cedar location(s): Arbuckle Mountains, OK
Regional weather: Friday, December 24 - TX/OK: High pressure will continue to govern the weather over the weekend. The upper-atmosphere Low in the Southwest will probably move a bit westward. Circulation around the High will bring moisture into sections of southern and western TX..... clouds and a chance of mostly light precipitation. Most areas of OK/TX will remain fair and dry. Temperatures will be seasonal to mild. Highs in the 50's and 60's today, mostly 50's Saturday. Lows tonight and Saturday night ranging from the 20's north to 40's south.
Trajectory weather: Mostly sunny today, high in the mid-50's. Partly cloudy tonight and Saturday, low in the 30's, high in the low 60's.
Trajectory confidence: High
OUTLOOK: *** Mild Threat *** Mixed conditions for pollen release. Temperatures are climbing slowly through the upper 40's to low 50's this morning and midday. The humidity has been dropping rather slowly and is only reaching the tolerance range by early afternoon. Recent reports from the Arbuckle Mountains indicate that many cones are now mature. Overall.... some pollen release will probably occur during the afternoon hours. Some residents of north-central and central TX may feel some ill effects as the airborne pollen flows south. TK
Trajectory Start(s) (shown by the * on map): Sulfur, Oklahoma
