Date Issued: 8 January 2010
Mountain Cedar Location(s): Arbuckle Mountains, OK
Regional Weather: Friday, January 8– TX/OK: Across
the region the weather will continue cold with high temperatures in the 20s and 30s today and warming into the
lower 40s across Texas tomorrow. In Oklahoma skies will be sunny and mostly sunny in northern Texas. Further
south partly cloudy skies will prevail after mostly cloudy skies across the Edwards Plateau lighten this morning.
High temperatures in Oklahoma will be around 20 degrees, whereas southward across the Plateau they will be in
the low 30s. In the surrounding communities highs will be in the mid to upper 30s. Strong winds yesterday will
relax to moderate levels in most places from the north. Higher wind strengths are expected in the communities
surrounding the Edwards Plateau. Tonight temperatures will be in the single digits north and across the Edwards
Plateau warming to the teens in north Texas and the communities surrounding the Plateau. Winds will continue from
the north and will be light to moderate. Saturday will remain cold but will warm by 5 to 10 degrees. Oklahoma
is expected to be in the low 20s to low 30s. Most regions in Texas will be in the mid 40s with the southernmost
areas in the upper 40s. Skies will be sunny and clear, winds will be moderate turning from the northeast to the
southeast and south. Saturday night low temperatures return to single digits in central Oklahoma and into the
upper teens in the remaining areas.
Trajectory weather: Sunny skies, cold conditions and moderate winds from the northwest will occur across
Oklahoma today. Tonight winds will slacken to light and variable conditions. Tomorrow, temperatures will be in
the low 20s to 30s and back into single digits and low teens Saturday night. Today the surface trajectories move
southward at ground level driven by moderate winds. The air appears heavy and cold. Because of cold temperatures
no pollen release is expected.
OUTLOOK: *** Low Threat today; Low threat tomorrow *** Poor conditions for pollen
release today and Poor conditions tomorrow; Poor conditions for entrainment and transport today, Poor conditions
tomorrow. Cold conditions with moderate wind speeds today decreasing to light and variable winds tomorrow provide
poor conditions for pollen release today and tomorrow. No pollen release is expected. Winds will be moving towards
the south on moderate winds. For these reasons the threat today and tomorrow is low and the chance of pollination,
entrainment and travel is poor.
Trajectory Start (s) (shown by black
