Weather Forecast Discussion Today will bring temperatures reaching the mid 30's at the warmest, overcast skies, and a chance of snow throughout the day. Dewpoints will be near 30 degrees. Winds will be primarily from the north, reaching speeds near 15 kts. 850 mb temperatures will stay below -5 C throughout the day. There is low surface pressure to the east today and high surface pressure to the west, which will make its way into the region over the next couple of days. Tomorrow will bring cooler temperatures, reaching the upper 20's at the warmest. Dewpoints will fall throughout the day, reaching below 20 degrees, and skies will become partly cloudy. Winds will be primarily from the north and wind speeds will drop below 10 kts. 850 mb temperatures will decrease below -10 C.

Air Quality model analysis and decision  Fine Particulate: The NOAA 6Z BC and Canadian models agree on mostly good PM2.5 over the next couple of days, a decrease compared to recent PM2.5 measurements, though they disagree on which days will have the relatively higher values. The GA Tech model disagrees with both and shows moderate throughout the period, but agrees with the NOAA 6Z BC model in that it shows PM2.5 values decreasing over the next few days. The Canadian smoke model shows minimal impact from wildfire smoke over the next couple of days. With multiple chances for precipitation over the next couple of days and increasing wind speeds through the beginning of next week, the likelihood of PM2.5 buildup will decrease.
