Date Issued: 8 January 2009
Mountain Cedar Location(s): Edwards Plateau, Texas
Regional Weather: Thursday, Jan 8. TX/OK: Mild
to warm conditions continue throughout the region today with clear skies and light variable winds. Temperatures
will range from the upper 50s in northern Oklahoma to the upper 70s and low 80s in southern Texas. Overnight temperatures
will be mild in the 40s and 50s. Tomorrow will start warm throughout the region with temperatures in the 60s and
70s. There will be moderate to strong southwest winds ahead of a strong cold front that will begin to enter the
region on Friday afternoon. Winds will shift to the northwest as the frontal system enters and temperatures will
begin dropping. Friday night will see temperatures in the 20s in Oklahoma and 30s and low 40s in Texas. Saturday
will be 20 degrees colder than current conditions.
Trajectory weather: The air mass trajectories from the Edwards Plateau move to the north, northeast today
over central Texas and Oklahoma. Conditions at the source areas are mild with warm temperatures and sunny skies.
Winds speeds are light this afternoon so much of the pollen will remain local today. Overnight temperatures will
be in the 40s and 50s. Temperatures will again warm tomorrow and winds will pick up ahead of the cold front with
good characteristics for long range transport.
OUTLOOK: *** High Threat today *** Good conditions for pollen release
and moderate conditions for pollen transport. Sunny, dry conditions and warm temperatures today are ideal
for pollen release. Winds are light throughout the region so much of the pollen may stay close to the source area.
The trees are nearing the peak of the pollen release season therefore significant pollen release should be expected
throughout the region.
