Temperatures will be in the teens today, down to single digits tonight, and back to the teens tomorrow. Friday night some areas may drop below 0 as the cold conditions into the weekend. Today and tomorrow, the surface trajectories move southward at ground level for long distances with the strong winds. The air appears heavy and cold. Because of cold temperatures no pollen release is expected.

OUTLOOK: *** Low Threat today; Low threat tomorrow *** Poor conditions for pollen release today and Poor conditions tomorrow; Poor conditions for entrainment and transport today, Poor conditions tomorrow. Cold conditions with strong wind speeds today decreasing to moderate winds tomorrow provide poor conditions for pollen release today and tomorrow. No pollen release is expected. Winds will be moving rapidly towards the south on strong winds. For these reasons the threat today and tomorrow is low and the chance of pollination, entrainment and travel is poor.
