Regional weather: Friday, January 5 - TX/OK/AR: Sunny/clear today and tonight region-wide. Weak front is moving through central sections today. Wind shift is the only item to mark its passage.

Trajectory weather: Sunny today, high in the mid-50's. Clear tonight, low in the 30's. Partly cloudy Saturday, high in the mid-50's.

Trajectory confidence: High

OUTLOOK: *** Low / Moderate Threat *** Conditions are mostly favorable for pollen release this afternoon. Temperatures and humidities will move into the favorable ranges during the afternoon hours. Winds are light to moderate. Given the expected shifts in wind direction (seen clearly in the trajectory), the greatest risk of exposure will be concentrated near to and just south of the source region. Moderate Risk of exposure for residents of south-central OK and extreme north-central TX. Low Risk of exposure elsewhere from this source. TK

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