Date Issued: 21 January 2010
Mountain Cedar Location(s): Edwards Plateau, Texas
Regional Weather: Thursday, January 21 – TX/OK:
Across the region the weather will remain seasonably warm with temperatures in the 70s today and tomorrow. Skies
will be sunny today across Texas with partly cloudy skies across Oklahoma. Winds will be light and variable to
the north and moderate from the west across Texas. Tonight clear to mostly clear skies will dominate the region.
Temperatures will be in the mid to upper 30s from central Oklahoma towards the border region with Texas. In Texas,

rest of the region. There will be a chance of isolated thunderstorms in communities surrounding the Plateau.
Winds will be from the south at moderate levels climbing to strong winds in the afternoon. Friday night skies
will be partly cloudy becoming mostly cloudy late. There is a 20% to 30% chance of precipitation in the form of
thunderstorms. Low temperatures will be in the mid to upper 50s with moderate to strong winds primarily from the
south except for the western regions of the Edwards Plateau where they will be out of the southwest.
Trajectory weather: Conditions today will be warm, and sunny across most of the Texas region. Winds will
be moderate from the west and temperatures in the mid to upper 70s in the communities surrounding the Edwards Plateau,
and in the low 70s in areas on the Plateau. Tonight mostly clear skies will prevail with temperatures in the mid
40s. Winds will be south at moderate conditions. Tomorrow the surrounding areas will be sunny once more, but
the Plateau will be partly cloudy. Winds will be from the south during the day starting at moderate conditions
and building towards strong conditions. Tomrrow night partly cloudy building to mostly cloudy conditions on the
Plateau will prevail. There will be a 20% to 30% chance of precipitation across the region and lows will be in
the 50s. Winds will be from the south at moderate levels with western areas of the Plateau being gusty with strong
winds from the southwest. The trajectories move towards the north to northwest today and tonight and then shift
towards the southwest tomorrow and tomorrow night. The atmosphere appears relatively stable for the next 24 hours
then becomes more buoyant across the region.
OUTLOOK: *** High Threat today; High threat tomorrow ***Good conditions for pollen
release today and Good conditions tomorrow;Good conditions for entrainment and transport today, Good conditions
tomorrow. Warm temperatures and sunny skies today, clear skies tonight, and sunny to partly cloudy skies tomorrow
along with building winds make for good pollen release conditions. On Friday night a chance of precipitation is
expected across the region. Winds will be moderate today and tonight increasing to gusty conditions tomorrow,
especially tomorrow afternoon on the Edwards Plateau. The atmosphere will begin relatively stable today but as
low pressure moves through the area it will become more buoyant. The high humidity and rain in the region on Friday
could wash out any pollen that might get into the atmosphere. Because of the good conditions for pollen release
as well as entrainment and travel a high threat exist today and tomorrow. .
