Mountain Cedar Pollen Forecast

 

Date Issued: 31 December 2001

Mountain Cedar location(s): Arbuckle Mountains, OK

Regional weather: Monday, December 31  TX/OK/AR: Cold northern air continues to be established over the southern plains.  High pressure over the area and increasing humidity will result in mixed cloud conditions to partly cloudy skies during the day today.  High temperatures in the central Texas region will only be in the mid to upper 40 s with a 10 degree cooling towards the north as Tulsa will only reach the lower 30 s.  Low temperatures will be in the upper 20 s to low 30 s to the south and mid 20 s to the north.   The Ozark Mountain region will remain below freezing today and into the teen tonight.  On Tuesday a trough will push over the area with significant lift over the Edwards Plateau and Hill Country to produce the chance of snow.  Skies will be cloudy throughout the southern plains.  Precipitation towards the southeast may fall as either rain or sleet depending upon the timing and storm development.  To the north the moisture source will be reduced.  Temperatures will remain cold with high temperatures barely getting into the 40 s in most places in Texas and remaining in the 30 s to the north.  Low temperatures will be below freezing to the south and in the 20 s and teens to the north.  Winds will be moderate to light and out of the north to northeast throughout the region.    

Trajectory weather:  The trajectories from the Arbuckle Mountains flow to the southwest, just west of the Dallas/Fort Worth region.  Weather conditions throughout northern Texas and southern Oklahoma will be cloudy and cold with high temperatures in the lower 40 s today and tomorrow.  Increased humidity will accompany the passage of a trough on Tuesday that may bring snow showers to the area.  Accumulation of an inch or more is possible during the day on Tuesday and into Tuesday evening. Winds will remain moderate to light out of the north to northeast

Trajectory confidence: High.

OUTLOOK: *** Low Threat *** unfavorable conditions for pollen release today. Conditions in southern Oklahoma will not favor pollen release today or tomorrow.  Cold temperatures, cloudy conditions and increased humidity will occur this afternoon.  A significant chance of precipitation, potentially as snow, is forecast for areas just south of the Red River.
