WEST MICHIGAN - After a week long forecast of high humidity/high dew point temperatures and readings in the upper 80s to around 90, we will finally begin breaking both the heat and humidity this week. Starting today, drier, more comfortable, less humid air will gradually filter in through the day. Dew point temperatures, a measure of moisture in the air, will go from low/mid 60s into the lower 50s by this evening. It will still be warm with highs in the middle 80s, but it will also become more comfortable by this evening. See dew point temperature forecast below.
