Date Issued: 14 January 2009
Mountain Cedar Location(s): Edwards Plateau, Texas
Regional Weather: Wednesday,
Jan 14. TX/OK: Mild
temperatures will dramatically change this afternoon and evening as a strong cold front moves across the southern
plains and Texas. Temperatures will be above average in the upper 50s in Oklahoma and low to mid 60s in Texas ahead
of the front. Skies will be clear to partly cloudy during the day today. In Oklahoma winds will be light variable
in the morning and shifting to moderate northerly winds as the front moves into the area this afternoon. In Texas
winds will be from the south and moderate during the day. The front will move through Texas during the overnight
hours bringing much colder temperatures for Thursday. Overnight tonight temperatures will be in the teens and low
20s in Oklahoma and 30s in Texas. Temperatures tomorrow will be in the 20s to low 30s in Oklahoma and 40s to low
50s in Texas with partly cloudy skies and moderate northeast winds.
Trajectory weather: The air mass trajectories from Edwards
Plateau move to the north and then circle around north central Texas. Each of the trajectories shows mixed characteristics
for downwind dispersal. Conditions at the sources will be warm and dry with sunny clear skies. The trees are
near the peak of the pollination season therefore significant pollen may be released. The strong cold front will
move through the state overnight tonight bringing colder conditions to the Plateau area for tomorrow. Overnight
lows will be in the 30s and highs tomorrow in the 40s.
OUTLOOK: *** High Threat today *** Good conditions for pollen release. Sunny
skies with dry conditions and warm temperatures are good for pollen release today. Since the trees are nearing
their peak release period significant amounts of pollen release might be expected. Across the region the cold air
will move into Texas overnight bringing lower temperatures and reducing the pollen release for tomorrow.
