Monday will be dry with low clouds in the morning decreasing by

afternoon with filtered sunshine. Ventilation will be low Monday
through Wednesday due to light winds and low afternoon mixing
heights. Better ventilation arrives Thursday and Friday, though
with higher humidity and precipitation chances. There is a 40%
chance for 0.10 inches of rain on both Thursday and Friday.

If conditions become unrepresentative, contact the National Weather
