Weather: Todays fairly heavy snowfall and fairly calm winds (at least around town – weather was reportedly considerably worse just a short ways up the mountains) will probably continue through tomorrow night. Periods of snow may continue through Monday night. The temperature may continue to rise, possibly close to freezing, until falling again on Tuesday or Wednesday.
Chemical: Sunday and Monday look interesting because it seems a large portion (50% or greater) of the predicted CO transport has a biomass burning source. In terms of volume of species, there aren’t really any significant plumes within the beginning of the week.
