December 23 TX/OK/AR:
Conditions across the southern regions will be wet today and tomorrow with winter weather across the Texas and
Oklahoma panhandle, extending to the east overnight and into Tuesday. Conditions will include rain and thunderstorms

in rain and thunderstorms across the southern Edwards Plateau region.
Cloudy conditions, high humidity and moderate winds will prevail across

the
OUTLOOK: *** Low Threat today*** unfavorable conditions for pollen release. Cold temperatures and cloudy conditions result in unfavorable conditions for pollen release today and tomorrow. Trees to the south have begun to pollinate thus signaling the beginning of the pollination season, however conditions are very cold to the north with cloudy, humid conditions. The trajectories show conditions that are conducive to entrainment and travel of pollen away from the source, but the overall poor weather conditions region wide indicates little chance of release at the source areas. Therefore there is a low threat for downwind travel today and tomorrow.
