WEST MICHIGAN — Summer officially arrived Friday June 20 at 10:42 P.M. and with summer we get our first big heat wave! We expect temperatures Saturday through Tuesday at 91 degrees or better. But that's only part of the heat and humidity. When you combine the two, we get what Meteorologists call to or refer as the heat index or feels like temperatures.
The National Weather Service in Grand Rapids has issued a HEAT ADVISORY for all of West Michigan for Saturday and Sunday. We expect this Advisory to be extended for Monday and Tuesday as we get closer to next week.
Forecast heat index values Saturday through Tuesday. Anywhere from 95 to 105 will be possible.
Keep mind our winds will be increasing this weekend too. If you're going to seek relief from the heat at the Lake Michigan shoreline, make sure to check the flag color that's flying on the beach you'll be at. A green flag means it's safe to swim. A yellow flag means exercise caution. And a red flag means swimming is not advised due to high waves, rip currents, structural currents, and possible longshore currents.
The high temperatures will set up a situation where unhealthy levels of ozone can build up. A Clean Air Action day has been issued for Saturday.
We should begin to see some relief from the heat and humidity along with some showers/storms by mid-week next week.
