FORECAST DISCUSSION:
July starts out with cool temperatures and low dew points as the center of surface high pressure moves over Michigan during the today. Temperature and humidity will increase as we move to mid-week but will stay in the seasonable (or slightly below) range.
As high pressure moves east of the region, southerly low-level winds bringing warmer air on Tuesday. There is a chance of rain showers during the day, particularly north of Grand Rapids with a slight chance thunderstorm during the day. Rain showers become more likely Tuesday night on the west side of the state.
A weak cold front is likely to move over the state during Wednesday but die out as it progresses. Above average warm temperatures with higher humidity expected for the 4th of July holiday and into Friday. Another round of storms could impact the region during Friday as atmospheric instability looks to increase.
Air Quality during the week should remain mostly Good but we could see some hit or miss Moderates.
EXTENDED FORECAST:
Air Quality is expected to remain Good to Moderate during the beginning of the upcoming weekend.
