Mountain Cedar Pollen Forecast

 

Date Issued: 14 Jan 2005

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Fri, Sat, and Sun, Jan 14 - 16. TX/OK: A cold high pressure system has moved in over the region, and reinforcing fronts will keep low temperatures in place for the next several days. Coldest conditions will be in northern Oklahoma. Daytime highs will be in the 20s and 30s in Oklahoma and the 50s in Texas. Night time lows will be in the teens and 20s in Oklahoma and the upper 20s and low 30s in Texas. Skies will be partly to mostly cloudy with low to moderate winds. Winds will be from the north in northern Oklahoma; wind direction will be variable in southern Oklahoma and Texas..

Trajectory weather: The air mass trajectories on Friday move from the Arbuckle Mountains to the northwest and then turn east. Trajectoris for Saturday and Sunday show air mass movement to the southwest and then shifting to the northeast and north. Partly to mostly cloudy skies will prevail across the region but low temperatures will occur at the source site today with below freezing conditions expected overnight.

OUTLOOK: *** Low to Moderate Threat Friday/ Low Saturday and Sunday *** mixed conditions for pollen release Friday, unfavorable Saturday and Sundy. Sunny dry conditions will occur today, but temperatures just getting into the low 40s will reduce the chance of any significant pollen release making for mixed conditions.  Cold temperatures tonight and contined low day time temperatures expected Saturday and Sunday. With cold, dry conditions little release is expected and therefore a low threat exists from Arbuckle populations. However, trajectories from the Texas populations may bring some pollen into Oklahoma for a low to moderate threat.

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