Date Issued: 21 December 2004
Mountain Cedar Location(s): Edwards Plateau, Texas
Regional Weather: Wednesday and Thursday, Dec 22 and
23. TX/OK: A strong arctic front will move across the southern plains on Wednesday dropping temperatures
20 to 30 degrees from Tuesdays readings. Temperatures in Oklahoma and north Texas will be in the upper 20s to upper
30s. Highs in south Texas will be in the 50s. Strong northerly winds throughout the area with a chance of precipitation
on Wednesday. Some areas in Oklahoma will receive snow and there is a chance of rain in parts of Texas. Frigid
temperatures will continue on Thursday and Friday as the cold air covers the region. Daytime highs will be in the
20s and 30s throughout the region. Night time lows in the single digits to teens in the north and low 20s in the
south.
Trajectory weather: The air mass trajectories from the
Edwards Plateau Texas move to the south. Each of the trajectories shows characteristics associated with the cold
air as the air masses sink towards the ground and move primarily at ground level as the cold air drains into the
area. Trajectories are not conducive to pollen entrainment and transport. Conditions at the sources will be
cool on Wednesday and very cold on Thursday.
OUTLOOK: *** Low to Moderate Threat Wednesday, Low
on Thursday *** Mixed
condition for pollen release on Wednesday. Temperatures are in the favorable range only in some areas.
The cold temperatures coupled with chance of precipitation will limit pollen release on Wednesday. Any pollen released
will remain local since trajectories are not favorable for pollen transport. On Thursday conditions will be too
cold for pollen release.
Trajectory Start (s) (shown by *
on map): Austin, TX; Junction, TX; San Angelo, TX.
