Mountain Cedar Pollen Forecast
Date Issued: 12 January 2001
Mountain Cedar location(s): Ozark Mountains, AR/MO
Regional weather: Friday, January 12 - TX/OK/AR: Weak high pressure over the region today will shift east as the next system approaches from the west. This frontal system will pass through the region on Saturday, triggering showers over most areas with the best chances to the north. Clearing later Saturday, clear to partly cloudy on Sunday. Low clouds and fog covering the eastern 2/3 of the region most of the day, rather than just half a day as thought earlier. High cloudiness invading the western sections this afternoon. Highs today and Sunday mostly in the 40's and 50's, 50's and 60's on Saturday. Lows ranging from the 30's to 50's tonight and Saturday night.
Trajectory weather: Cloudy with fog today, high in the 40's. Partly cloudy with fog developing tonight, low near 30. Cloudy with a good chance of rain on Saturday, changing to snow. Temperatures dropping in the 20's.
Trajectory confidence: High
OUTLOOK: *** Low Threat *** Conditions are unfavorable for pollen release. Scenario for this source area very similar to the others.... too moist and cool today for release. Very good (80%) chance of rain on Saturday, again too moist. Sunday, it will have rained the day before and temperatures will be borderline. No release expected today through Sunday, with Low Risk of exposure. TK
Trajectory Start(s) (shown by black star on map): Oak Grove, AR
