Tonight rain is expected and temperatures will drop only 5 to 10 degrees from daytime levels. Winds will switch
from the southeast to the northeast overnight.
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. Warm temperatures today, tonight, tomorrow and tomorrow night would be good for pollen release, but
precipitation is expected across the region over the next two days. No pollen release is expected because of the
wet weather conditions. Winds will be moderate today increasing to gusty conditions in the edge communities tomorrow.
The atmosphere will begin relatively stable today but as low pressure moves through the area it will become more
buoyant. The high humidity and rain in the region should wash out any pollen that might get into the atmosphere.
With no pollen expected to be released to the atmosphere conditions for entrainment and travel is of minor importance.
