Scorcher: Significant Heat this Weekend


GRAND RAPIDS, Mich. (WOOD) — Today (Sat.) we’ll see some of the highest heat index values since the July 2012 heat wave (which brought the warmest temperatures to the area since 1936).

While the warm pattern will continue through next week, the warmest day may be Saturday.

High temperatures (below) were between 88° and 92° Friday.  It was cooler at Lake Michigan.  The high at the Muskegon Beach was 79.7°.  Heat index readings Friday afternoon reached 100° in Grand Rapids and 103° at the Regional Airport in Holland. 

These are forecast heat index values for late Friday afternoon:

Dew points (the direct measure of moisture in the air) will surge into the low-mid 70s. 

A very weak cool front will move through Sunday, but it won’t do much to beat back the heat. Highs will still be generally in the upper 80s to low 90s through next Friday.  The front may touch off a random shower or t-storm anytime from Sun. PM to Mon. AM.  However, humidity will be knocked down just a bit on Monday. 

The heat wave will continue in some form for the rest of the week with highs near or above 90 degrees through the end of next week.

The federal government reminds people under extreme heat warnings to avoid strenuous activities, keep an eye out for heat illnesses, and check on your family and neighbors to make sure they’re OK. More extreme heat safety tips can be found at
