Air Quality model analysis and decision  Fine Particulate: The NOAA 06Z has low moderate or good forecast through Monday and the GEM-MACH is low moderate as well. Recent observations were good all week across the region with widespread moderates on Thursday only. I do think that with a snowpack in place once again by tomorrow morning, there is a chance of trapped PM2.5 getting released once warming begins on Monday, but it is expected to be very windy which should mitigate those impacts. Otherwise, temperatures over the next 48 hours will be below freezing as the previously mentioned cold airmass settles in. The forecast is good through Monday with a chance of very low moderates on Sunday as forecasted highs reach around 31 F. Finally, wildfire smoke is not expected impact the forecast area over the next 72 hours according to the FireWork model.
