GRAND RAPIDS — The forecast from FOX 17 Chief Meteorologist Kevin Craig: Look for mostly sunny to partly cloudy and hot conditions as our heat wave of 90 degrees or better continues this week. We'll also increase the humidity with minimal chances for an isolated shower/storm in the afternoon hours, especially inland. If you get caught under one of these showers, there will likely be a brief, heavy downpour, but consider yourself lucky as they will be very scattered. Our best chance for more widespread, prolonged showers/storms arrive on Friday with a stronger frontal system. Behind this system, high temperatures will cool back into the mid 80s this weekend, but there are indications more heat may build back in during the following week.
TONIGHT: Mostly clear and warm. Lows in the mid/upper 60s. Winds southwest light.
