Date Issued: 21 January 2007


Mountain Cedar Location(s): Arbuckle Mountains, OK


Regional Weather: Sun and Mon, Jan 21 and 22. TX/OK: There will be varied weather conditions across the region on Sunday and Monday. Today will bring warmer temperatures after the cold conditions of last week. High temperatures in Oklahoma today will range from the upper 30s to the upper 40s with cloudy skies and light variable winds. Texas will have mild temperatures ranging from the mid 50s to the mid 60s with clear to partly cloudy skies and variable winds. By late afternoon the winds will be shifting to the north as the next cold front begins moving into the region. Overnight lows will range from the mid 20s in Oklahoma to the mid and upper 30s in Texas. Monday will bring cloudy skies and moderate northerly winds to the area. Highs on Monday will be in the mid 30s in Oklahoma and the mid 40s in Texas. There is a chance of rain and even areas of freezing rain in Texas on Monday.

Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the southeast. The trajectories are associated with a cold sinking air and show poor characteristics for entrainment and travel. Temperatures at the source will reach the favorable range but after the wet weather, pollen cones may not be dry enough for pollen release. Trajectories on Monday move to the south with poor characteristics for entrainment and travel. Conditions on Monday will be unfavorable for pollen release.

OUTLOOK: *** Low threat *** Conditions are marginal for pollen release today and unfavorable on Monday.


Trajectory Start (s) (shown by black star on map): Sulfur, OK.
