Regional Weather: Wednesday December19. TX/OK:
Winds throughout the region will be shifting to the north over night and into tomorrow. Partlycloudy conditions
today will begin to clear in the morning with sunny conditions warming from the mid-40s into the lower 60s by tomorrow
afternoon. There is a 20% chanceof precipitation overnight falling to 0% by tomorrow at noon. Humidity will be
high overnight but then will fall below 50% by tomorrow afternoon.
Trajectory weather: The air mass trajectories move from the Arbuckle Mountains to the north over central
Oklahoma intosoutheastern Kansas overnight. The trajectories are associated moderately rising atmospheric conditions,
which are good characteristics for entrainment and travel. However, there is no indication that the trees are
releasing pollen at this time. Atmospheric monitoring further south in Texas shows somewhat mixed levels. Trees,
may be beginning to shed pollen, however we do not feel that significant atmospheric concentrations have yet occurred.
OUTLOOK: *** Low threat *** Conditions are marginal forpollen release
today. At this time we do not have confirmation that the trees have started to pollinate.
Trajectory Start (s) (shown by black
