The Grand Rapids National Weather Service said: “
WE HAVE ISSUED A FROST ADVISORY FOR EARLY THURSDAY MORNING FOR THE FAR NORTHERN INTERIOR OF THE FORECAST AREA. CONDITIONS WILL BE MARGINAL AS DEW POINTS ARE PROGGED TO BE IN THE UPPER 30S TO LOWER 40S OVERNIGHT, BUT WITH LIGHT WINDS AND CLEAR SKIES, THE COLD HOLLOWS COULD SEE FROST FORMATION. ELSEWHERE, FOG COULD BE A PROBLEM EARLY THU. MORNING. GIVEN THE HIGH LOW LEVEL RH, STEAM FOG FROM RIVERS AND LAKES, AND STILL MOIST GROUND IN MANY AREAS. TRANQUIL WEATHER FOR THURSDAY UNDER SHORTWAVE RIDGING. TEMPERATURES COULD ONCE AGAIN REACH THE UPPER 30S ACROSS THE NORTHERN INTERIOR ON THURSDAY NIGHT WITH SURFACE RIDGING BRINGING GOOD RADIATIONAL COOLING CONDITIONS". We should also see a fairly heavy dew Friday morning. A period of rain is likely over the weekend. I can't rule out a shower on Saturday, but showers are most likely later Saturday night and Sunday.
Friday will be mostly sunny and dry. A shower could sneak in late Saturday, with a better bet for showers Saturday night and Sunday.
