Date Issued: 03 January 2002

Mountain Cedar location(s): Arbuckle Mountains, OK

Regional weather: Thursday, January 03  TX/OK/AR: High pressure associates with the cold northern air that has been centered over the southern plains will begin to move east as the winter storm on the east coast moves out.  This will return southerly winds to the area and result in a general warming of high temperatures.  High temperature readings throughout the southern plains will be in the low 50 s to upper 40 s today with sunny conditions.  To the north in Oklahoma high temperatures will reach the mid 40 s but the Ozark Mountain region will remain around freezing.  The shift in winds will increase to moderate wind strengths to the north but stay calm to the south.  As the afternoon progresses the southerly winds will bring increasing moisture causing clouds to build across the southern area towards the evening.  Low temperatures on Thursday will return to the mid 30 s to the south, mid 20 s in Oklahoma and back to the teens in the Ozark Mountains.  On Friday, conditions will continue to warm with high temperatures again reaching the low 50 s but low temperatures will stay in the mid 40 s.  Southerly winds will continue to bring in moisture and cloudy conditions will prevail across the Edwards Plateau and hill country.  Clouds will build across northern Texas and Oklahoma with a significant chance of rain occurring in the Dallas area and southern Oklahoma.  Winds will continue out of the south at moderate strengths.             

Trajectory weather:  The trajectories from the Arbuckle Mountains move quickly to the north before turning towards the east.  Weather conditions throughout Oklahoma will remain cold with highs in the mid 40 s.  The day will begin sunny but increased humidity will result in increasing cloudiness towards the afternoon and into the evening.  Continued cloudiness will occur on Friday with an increased chance of rain on Friday evening going into Saturday.   Winds will remain moderate and from the south throughout today and tomorrow.

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, sunny conditions this morning but clouds and higher humidity will build this afternoon and into tomorrow.  Rain is forecast by Friday afternoon into Saturday.  The area should remain clear of significant Juniperus ashei pollen release and transport.
