981 FNUS73 KMQT 101155 FWSMQT Spot Forecast for Fuji Rx...USDA Hiawatha NF National Weather Service Marquette MI 755 AM EDT Fri May 10 2024 Forecast is based on ignition time of 0800 EDT on May 10. If conditions become unrepresentative...contact the National Weather Service. .DISCUSSION... .REST OF TODAY...High pressure currently over Upper Michigan will give way to a clipper low pressure system this afternoon, bringing in some showers to the spot forecast area tonight. Mixing this afternoon will result in min RHs around 30%. While confidence is high for light winds, the forecasted wind direction is not as certain. High pressure earlier today plays part of that role in uncertainty, but the lake breezes off Lake Michigan and Lake Superior will complicate things this afternoon. These lake breezes will result in some increased cloud cover and may result in a few sprinkles after noon. They will also help elevate RHs by bringing in some moisture off the water. Chances for showers increase tonight, continuing into Saturday as the clipper system makes its way through. This will also yield RH recovery to near 80%. Gradual clearing is expected Saturday afternoon with higher min RHs in the low 60s to upper 50s and northerly winds with gusts up to 15 mph. Sky/weather.........Mostly sunny (30-40 percent).
