FORECAST SUMMARY: friday may 31, 2024 Through monday june 3
OZONE: Ozone concentrations are expected to be in the Good (Green AQI) to low-Moderate (Yellow AQI) range.
PM-2.5: PM-2.5 concentrations are expected to be in the Good (Green AQI) to low-Moderate (Yellow AQI) range.
FORECAST DISCUSSION:
We end the month of May on a high note with sunny skies and surface temperatures ranging from the 60s to the 70s throughout the state. A High-pressure system is sitting just to our southeast providing these weather conditions. The current conditions begin to erode as a rather weak frontal boundary crosses over the state tomorrow, Saturday, morning into Saturday afternoon. This will provide spotty rain showers across the state while dropping temperatures slightly. The rebound comes on Sunday as we stay mostly dry with temperatures ranging from the 60s to 70s as we start off the first week of June.
Due to somewhat stagnation today, Friday, PM-2.5 concentrations can be expected to hang around the Moderate range, but no higher than mid-high Moderate. The boundary coming through on Saturday will help to clean out any buildup with Sunday having residual concentrations hanging around, but nothing higher than the low-Moderate range. For Ozone, temperatures are still too cool for any serious Ozone development. Surface winds are looking to stay mainly southerly until Sunday, which may allow for Moderate concentrations over Lake Michigan and into the eastern Upper Peninsula. Numerous Ozone forecasts are showing low-mid Moderate concentrations over the lake and slowly moving north up the lake due to the winds. As just stated, however, Moderate concentrations are expected at worst in some lakeshore areas.
EXTENDED FORECAST:
We start off June with pretty typical surface temperatures for this time of the year, however a cool down is expected for later next week. Air Quality should remain in the Good to Moderate range.
