Fire Weather Planning Forecast for Southeast Michigan
National Weather Service Detroit/Pontiac MI
248 PM EDT Sun Aug 24 2025

.DISCUSSION...Below normal temperatures through much of the week.
Ongoing shower activity this afternoon will wane as we lose daytime
heating in most areas. Monday will feature a cooler day, with highs
in the 60s and periodic showers. Deep mixing will allow for mixing
heights to approach 5-8kft, thus dew points should mix out well
during the afternoon to support RHs falling into the 40% range. This
decreasing humidity trend continues through mid week. Backdoor cold
front arrives Thursday, bringing north to northeast winds and
another round of precipitation.
