AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)

Forecast Discussion: Current Conditions as of 1 PM on Friday: Strong northwesterly flow has brought a cold, clean, and dry air mass to the region. Temperatures are looking to remain near to below normal for most of the forecast period with a few threats for wintry weather next week. *** Saturday’s Forecast: The strong westerly flow will continue on Saturday, though gusts will not be quite as high as they were on Friday, with temperatures once again struggling to climb above the mid-30s. The cold, clean, and dry air mass will continue to keep PM-2.5 concentrations inside the good range. High pressure will begin to build over the region, allowing for some clearing across the area as lake effect snow showers continue to stay well to our north and west. *** Sunday’s Forecast: High pressure will slide to our east early on Sunday, allowing for the flow to turn to more of a southerly breeze. Even with southerly flow, we will not see temperatures rebound much. Highs for the day are expected to only reach the upper 30s. The next storm system that will bring precipitation to the region will begin to approach on Sunday as well. With increasing moisture late on Sunday due to the approach of this system, PM-2.5 concentrations should climb into the low moderate range. *** Monday’s Forecast: A storm system will bring precipitation northward into the area early on Monday. Precipitation type at the start of the event is expected to be snow that will change over to freezing rain and eventually to a cold rain as temperatures warm just enough to get above freezing. Moderate levels of PM-2.5 for the early hours of Monday will see concentrations fall back into the good range as the system arrives. The southerly flow will turn to westerly by the afternoon as the precipitation ends from west to east. Depending on the exact track of the system, we may see just enough warm air push northward that temperatures will briefly climb into the 40s before falling back to the 30s with the westerly turning of the flow. *** Extended Outlook: High pressure will make another brief appearance on Tuesday, allowing for more stable conditions. As a result, PM-2.5 concentrations will push back into the low moderate range across much of the area. Under a mix of sun and clouds, temperatures will be seasonable with highs near 40 degrees. Another disturbance and cold front arriving on Wednesday will bring another shot of colder air, but also improving air quality. This next system could bring a better chance for some snowfall across areas on the eastern half of the state than the early week event. Snow or not, unseasonably cold air will move in for the end of the work week and stay into the weekend. Good air quality late in the week could return to moderate levels over the weekend as well. --- Roble
