317 FNUS53 KDTX 090741 FWFDTX Fire Weather Planning Forecast for Southeast Michigan National Weather Service Detroit/Pontiac MI 341 AM EDT Fri May 9 2025 .DISCUSSION...After a cold start to the day, full sunshine and dry conditions will prevail today. Given the significant amount of dry air aloft, did lower dewpoint temperatures and thus afternoon minimum relative humidity values as some of the drier air aloft is expected to mix down to the surface. With north winds of 10 to 15 mph today, the onshore flow for areas immediately along the Lake Huron shoreline will help keep temperatures cooler and thus RHs more elevated at 35% and higher. Inland from Lake Huron, warmer temperatures and more efficient mixing of drier air down to the surface will favor RHs falling into the 20-30% range. A cold front drops south across the area on Saturday, bringing a chance for a few isolated showers and reinforces gusty north to northeast winds during the afternoon hours. Winds lighten up as we head into the latter half of the weekend and early next week. A slow moving system will lift into the region next week, bringing periodic chances for showers and perhaps a few thunderstorms.
