AN AIR QUALITY ADVISORY REMAINS IN EFFECT ACROSS ALL OF WISCONSIN UNTIL 11 PM FRIDAY NIGHT.
Canadian wildfire smoke will create hazy skies this evening. Air quality may drop into the Unhealthy for Sensitive Groups range at times, but much of the smoke looks like it will remain aloft.
Tonight a few clouds will move through as lows fall into the upper 50s and low 60s.
Highs jump into the mid 80s on Saturday with lots of sunshine. It will be breezy with south wind gusts up to 25 mph. Dew points will climb into the low 60s, making it feel a little sticky.
Humidity will continue to climb on Sunday, as will the heat. Highs will top out around 90-degrees, and it will feel a little warmer thanks to the humidity. However, a cold front will swing through mid-day Sunday, which will turn winds off the lake, helping to bring a bit of relief from the heat in the late afternoon and evening.
Temperatures will be near average Monday and Tuesday, but it looks like it will turn hot Wednesday and Thursday of next week.
The Wisconsin DNR issued an air quality advisory. According to their statement:
Smoke originating from wildfires in Canada will move into the state from the northwest Thursday morning and travel south southeast throughout the day. The PM2.5 air quality index (AQI) is expected to range from the UNHEALTHY FOR SENSITIVE GROUPS (USG) level to the UNHEALTHY level. Remember, the UNHEALTHY AQI level is unhealthy for everyone. People with heart or lung disease, older adults, and children should consider avoiding prolonged or heavy exertion and everyone else should consider reducing prolonged or heavy exertion.
The best chance for UNHEALTHY AQI PM2.5 will reside across western Wisconsin on Friday as high pressure moves over the state and limits atmospheric mixing.
Over the weekend, the ozone AQI is expected to range from the USG level to the UNHEALTHY level due to favorable weather conditions alongside the presence of wildfire smoke. On both Saturday and Sunday, mostly USG AQI ozone concentrations are expected inland of the lake breeze, while those areas within the lake breeze will have a better chance of reaching UNHEALTHY AQI ozone concentrations. Remember, ozone concentrations are typically maximized during the afternoon or evening before decreasing overnight into the next morning.
