Mountain Cedar Pollen Forecast

 

Date Issued: 17 Jan 2005

Mountain Cedar Location(s): Arbuckle Mountains, OK

Regional Weather: Monday and Tuesday, Jan 17 and 18. TX/OK: Gradual warming temperatures over the next few days as the arctic air mass slowly releases its hold on the region. Daytime highs on Monday will be in the 30s in Oklahoma and the 40s and 50s in Texas. Nighttime lows will be in the 20s and 30s. Tuesday will be a little warmer with highs in the 40s and 50s throughout the region. Skies will be partly to mostly cloudy both Monday and Tuesday. Winds will be low to moderate from the southeast or south in Oklahoma and from the east or southeast in Texas. Wednesday will see temperatures at or above normal throughout the region.

 

Trajectory weather: The air mass trajectories on Monday move from the Arbuckle Mountains to the north and then northeast. Tuesday's trajectories follow a similar path. 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 again overnight. Some warm-up tomorrow but temperatures are still below the optimum range for pollen release.

OUTLOOK: *** Low Threat *** unfavorable conditions for pollen release. Dry conditions will occur Monday and Tuesday, but temperatures in the 30s and 40s will reduce the chance of any significant pollen release making for unfavorable conditions.  Cold temperatures tonight and a bit of warming tomorrow, 5 to 10 degrees is expected tomorrow.  With cold, dry conditions little release is expected and therefore a Low threat exists for downwind travel.

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