Low to Moderate today/Low tomorrow

St. Louis MO



Date Issued: 15 Dec 2004

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Wed and Thurs, Dec 15 and 16. TX/OK: Sunny to partly cloudy skies and southerly winds will help warm temperatures from yesterday. Temperatures throughout the region will range from the upper 40s in the north to the mid-50s in the south with night time lows near freezing. Clouds will increase tonight and remain across the region tomorrow but chances of rain are low. Temperatures tomorrow will be a few degrees warmer than today but winds will shift back to the north during the day. Skies will clear on Friday with temperatures remaining in the 50s.


Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the north, northeast and then continue east. Temperatures at the source were low this morning hindering pollen release. Pollen release is more likely this afternoon with warming temperatures and conditions are good for transport. However it is early in the season and the morning low temperatures will limit release to moderate levels. Trajectories tomorrow show movement to the south as the winds swing back to northerly.Any pollen released from the Arbuckles Mountains will move into Texas.

OUTLOOK: *** Moderate Threat *** Sunny dry conditions will occur today, but cold morning temperatures and early seasonal time reduce the chance of significant pollen release making for mixed conditons for release. Cold temperatures occur again tonight and a slight warming is expected tomorrow. Overall threat is moderate for the area around the Arbuckles and low to moderate downwind.

Trajectory Start (s) (shown by black star on map): Sulfur, OK.
