FORECAST SUMMARY: Monday August 15th, 2022, through August 19th, 2022
OZONE: Ozone concentrations are expected to be in the Good to low-Moderate range for the forecast period.
PM-2.5: PM-2.5 concentrations are expected to be in the Good to low-Moderate range for the forecast period.
FORECAST DISCUSSION:
The pleasant weather Michigan experienced this past weekend looks to continue as we start off this mid-August week. For the majority of this week, surface temperatures hang around the 70s with southern Michigan eclipsing the 80-degree mark on some days. We also look to remain dry as High-pressure helps to keep rain chances at bay. The High-pressure also causes surface winds to predominately have an eastern component to them. Throughout the week, winds will shift from northeasterly to southeasterly, but as stated, will mainly be easterly. Upper-level winds mirror surface-level winds with northeasterly and southeasterly flow along with upper-level temperatures in the low teens for much of the week.
In terms of air quality, PM-2.5 concentrations will not be of concern this week. With light morning winds, however, concentrations will build up due to morning commute activity. As the day carries on, those concentration will dissipate as winds pick up. For Ozone, although this week will be rather sunny, winds shifting from northeasterly to southeasterly will keep Ozone precursors at bay and will diminish the threat of Ozone development substantially. Also, cooler upper-level temperatures will lower the already small threat of Ozone developing.
EXTENDED FORECAST:
As we go into the weekend, rain chances increase slightly with a few Low-pressure systems entering and exiting the area. This will help keep air quality in the Good category.
