Date Issued: 13 December 2002

 

Mountain Cedar Location(s): Ozark Mountains, AR/MO

 

Regional Weather: Friday, December 13 TX/OK/AR: Conditions across the region will improve today towards the south as high pressure begins to build over Texas in western Oklahoma.  A significant weather system is currently stationed over Arkansas bringing rain and a rain/snow mix to higher elevations in eastern Oklahoma and Arkansas.  This system will move towards the east leaving clearing skies this afternoon into evening and fro tomorrow.  Across the rest of the region sunny skies will prevail.  Temperatures will be in the high 50s to low 60s to the south and low 50s across Oklahoma.  Tonight temperatures will cool into the mid 30s with clear skies.  On Saturday sunny conditions will be the rule across the region with warming conditions and temperatures in the upper 50s and lower 60s region wide.  As this warming occurs and skies clear the area will dry out and humidity will be on the decrease.  Winds will remain light to moderate from the north to northwest today switching to southwesterly breezes overnight and into tomorrow.  Overall wind speeds will decrease on Saturday.

 

 

Trajectory weather: The air mass trajectories from the Ozark Mountains move to the southeast on light to moderate winds following the air movement associated with the weather system that will be leaving the area.  Conditions throughout the Ozark Mountains will begin today cold and wet with significant rainfall expected in Fayetteville.  Conditions will begin to improve this afternoon and into the evening hours with mostly sunny skies and warmer temperatures expected on Saturday.

 

OUTLOOK: ***Low Threat today***unfavorable conditions for pollen release today. Conditions in the Ozark Mountains are unfavorable for pollen release and there is a low threat for entrainment and travel today.  Low temperatures, wet weather and cloudy skies will characterize the region today but with clearing beginning this afternoon and into evening.  Conditions on Saturday begin to improve with clearing skies, lower humidity and warmer temperatures.
