NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Jan 31, 9:15 PM EST, 2 hours 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 915 PM EST WED JAN 31 2007 .UPDATE... AT 02Z THE KGRR 88D AND SFC OBS INDICATE NOTHING MORE THAN A FEW FLURRIES IN OUR AREA. HOWEVER A FEW SNOW SHOWERS SHOULD BEGIN TO DEVELOP DURING THE NEXT 1-3 HRS. NUMEROUS OBS SITES OFF TO OUR WEST IN WI INDICATE 1 TO 3 MILE VISBYS IN LIGHT SNOW. THIS AREA OF SNOW WILL BE ENHANCED BY THE SW FLOW OFF LAKE MI AS IT MOVES INTO OUR WESTERN/NW CWA AFTER MIDNIGHT. OUR GOING FCST AND THE LAKE EFFECT SNOW ADVISORY HEADLINE APPEARS TO BE IN GOOD SHAPE AND NO HEADLINE CHANGES ARE PLANNED. I SUSPECT THAT SNOW ACCUMS OVERNIGHT WILL MOST LIKELY END UP IN THE LOWER END OF OUR FCST RANGES (GENERALLY AROUND 1 TO 2 INCHES BY DAYBREAK OVER OUR WESTERN/NW CWA). HOWEVER WE CANNOT RULE OUT A FEW LOCALLY HIGHER AMOUNTS GIVEN SW FLOW LAKE ENHANCEMENT. BOTTOM LINE... OUR GOING FCST APPEARS REASONABLE SO NO EVENING UPDATE WILL BE NECESSARY. WE WILL UPDATE THE LAKE EFFECT SNOW ADVISORY STATEMENT AT 03Z. && .GRR WATCHES/WARNINGS/ADVISORIES...LAKE EFFECT SNOW ADVISORY FROM 1 AM THURSDAY THROUGH 1 PM THURSDAY FOR MASON...LAKE...OCEANA... NEWYAGO...MUSKEGON...OTTAWA AND KENT. SMALL CRAFT ADVISORY FOR THE NEARSHORE WATERS THROUGH THURSDAY AFTERNOON. && LAURENS
