FNUS73 KMQT 152019 FWSMQT Spot Forecast for Black River...MI DNR National Weather Service Marquette MI 419 PM EDT Thu Oct 15 2026 Forecast is based on forecast start time of 1800 EDT on October 15. If conditions become unrepresentative...contact the National Weather Service. .DISCUSSION... A low pressure tracking over the Great Lakes has brought rain back to the area this afternoon. Rain continues through the overnight hours, transitioning to lake effect rain showers Friday morning as a cold airmass presses in from the west. Total rainfall amounts are expected around 1 inch. RH remains very high through Friday morning as temperatures settle into the mid 30s. The cool and wet conditions yield poor ventilation into Friday morning. North winds increase Friday morning with gusts between 25-30 mph; a few gusts up to 35 mph are possible. Then drier air filters in ending precipitation by the afternoon when winds gradually taper off. Temperatures warm into the mid 40s and RH only falls into the mid 50s on Friday. High pressure brings back mostly clear skies, warmer daytime high temperatures, lower RH, and dry weather into the weekend. .TONIGHT... Sky/weather.........Cloudy (90-100 percent). Rain.
