Date Issued: 10 Dec 2004
Mountain Cedar Location(s):
Arbuckle Mountains, OK
Regional Weather: Friday, Saturday and Sunday,
Dec 10 to 12 . TX/OK: A cold front pushed into the area over night dropping
temperatures some on Friday and bringing strong winds from the north, northwest. Temperatures are still mild and
will remain so for the weekend. On Friday daytime highs will be in the 60s and 70s in the south and 50s in the
north. Skies will be mostly clear throughout the region. On Saturday winds from the north in the morning and gradually
shifting around to the south in the afternoon and evening. Saturday and Sunday will see daytime temperatures mostly
in the 60s (70s in the south) throughout the region with light southerly winds. Nighttime temperatures will be
mild. Skies will be sunny to partly cloudy on Saturday and Sunday. The next frontal system will enter the area
on Sunday .
Trajectory weather: The air mass trajectories
move from the Arbuckle Mountains to the southeast over eastern Texas and Louisiana today and into the Gulf of Mexico.Trajectories
are not optimal for pollen entrainment with the cold sinking air. Trajectories on Saturday travel to northeast
Oklahoma and into Missouri and characteristics are better for entrainment. If Arbuckle populations are releasing
pollen, we may see some in northeast Oklahoma. Sunday's trajectories suggest that any pollen released will remain
in southern Oklahoma and north Texas.
OUTLOOK: *** Low threat today/ Low to Moderate
Saturday and Sunday ***
Good conditions for pollen release. Sunny dry conditions
will occur today and this weekend, but it is early in the season and we do not have confirmation that the trees
in the Arbuckles have started to pollinate. Trajectory characteristics are not optimal for pollen entrainment today
but will improve tomorrow and Sunday.
Trajectory Start (s) (shown by black
star on map): Sulfur, OK.
