Monday, June 15th, 2020 through Tuesday, June 16th, 2020

FORECAST DISCUSSION
Dry weather and mostly clear skies are expected through the end of the work week. Monday morning starts off cool with afternoon highs nearing 80 degrees under light easterly winds and dew points in the upper 40’s. Upper air temperatures remain cool which should help maintain Good Air Quality through Monday. This pattern should persist through Tuesday with slightly higher temperatures and dew points. Air Quality should generally stay in the Good category but some areas in southeast Michigan may reach Low Moderate during Tuesday.
The real warmup begins on Wednesday when surface temperatures are expected to reach the mid-80’s. Upper air temperatures are still a bit on the cool side, which should help subdue ozone numbers, but the long daylight hours and strong sun may start pushing numbers towards the USG mark, in certain areas.
The hottest days will likely occur on Thursday and Friday when afternoon temperatures in the upper 80’s and the dew points near 60 are expected. Upper air temperatures are still not optimal for ozone development, but the long days and strong sun may dominate ozone development near the surface.
Having already seen a couple of days with decent ozone development in the past two weeks, I think it will be smart to keep a daily watch on developing situations. As such, this forecast will be updated, tomorrow, and likely each day this week.
EXTENDED FORECAST:
Air Quality should remain mostly Good early in the week, with Moderates by midweek, and declining Air Quality by the end of the work week.
