NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Jan 14, 3:15 AM EST, 5 hours 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 315 AM EST SUN JAN 14 2007 .SHORT TERM... A WINTER WX ADVISORY CONTINUES IN EFFECT UNTIL 4 PM THIS AFTN FOR THE SOUTHERN HALF OF OUR CWA. 00Z GFS AND NAM GUIDANCE CONTINUES TO SUGGEST THAT MIXED PCPN WILL GRADUALLY BECOME MORE PREVALENT ACROSS OUR SOUTHERN CWA THROUGH THE MORNING AND LIGHT FZRA HAS ALREADY BEEN REPORTED IN AZO AND LAN. FCST SOUNDINGS SUGGEST THAT A MIX OF LIGHT FREEZING RAIN AND SLEET IS LIKELY THIS MORNING INTO EARLY TO MID AFTERNOON ROUGHLY ALONG AND SOUTH OF I-96. WE WILL CONTINUE TO CARRY CHC POPS FOR SNOW SHOWERS FOR OUR NORTHERN CWA TODAY WHERE PCPN TYPE SHOULD NOT BE AN ISSUE. THE PRIMARY LOW PRESSURE SYSTEM WILL CONTINUE TO BECOME BETTER ORGANIZED AND MOVE TO BETWEEN IND AND CVG BY 06Z MONDAY. PCPN IN ASSOCIATION WITH THIS SYSTEM WILL DEVELOP ACROSS OUR SOUTHERN CWA THIS EVENING AND THEN GRADUALLY OVERSPREAD OUR CWA FROM SOUTH TO NORTH OVERNIGHT. WE WILL ISSUE A WINTER STORM WATCH FROM TONIGHT THROUGH NOON MONDAY FOR OUR SOUTHERN TWO TIERS OF COUNTIES (INCLUDING THE AZO... BTL... LAN AND JXN METRO AREAS) FOR A MIX OF FZRA... SLEET AND SNOW AND POTENTIAL FOR LGT TO MDT ICING TO OCCUR WHERE PCPN TYPE IS MAINLY FZRA. NAM FCST SOUNDINGS FOR THE I-94 CORRIDOR FOR TONIGHT SHOW CONSIDERABLY MILDER TEMP PROFILES ALOFT AND IMPLY THAT A MIX OF SLEET AND FZRA IS MOST LIKELY AND FZRA COULD BE THE PREDOMINANT PCPN TYPE FOR MUCH OF THE NIGHT. ON THE OTHER HAND GFS FCST SOUNDINGS FOR THE I-94 CORRIDOR CERTAINLY EXHIBIT COOLER TEMP PROFILES AND IMPLY PCPN TYPE WOULD BE MAINLY SNOW. WE WILL MENTION A MIX OF SNOW... SLEET AND FZRA TONIGHT FOR OUR SOUTHERN TWO TIERS OF COUNTIES BEFORE A GRADUAL TRANSITION TO ALL SNOW TAKES PLACE BY AROUND 10-12Z MONDAY AS COLDER AIR WRAPS IN ON THE BACK SIDE OF THE LOW PRESSURE SYSTEM. THANKS FOR THE COORD ON THE WATCH HEADLINE DTX AND IWX. FCST SOUNDINGS SUGGEST PCPN TYPE WILL BE ALL SNOW ACROSS ROUGHLY THE NORTHERN HALF OF OUR CWA TONIGHT THROUGH MONDAY. AS FOR TOTAL SNOWFALL UP NORTH... NAM GUIDANCE CONTINUES TO BE MUCH MORE AMBITIOUS WITH QPF AS COMPARED TO THE GFS. FOR INSTANCE FOR LDM THE COBB SNOW TOOL GIVES LDM 7 INCHES OF CUMULATIVE SNOWFALL FROM MIDNIGHT TONIGHT THROUGH NOON MONDAY. HOWEVER THE COBB SNOW TOOL BASED OFF OF 00Z GFS GUIDANCE QPF ONLY GIVES LDM 3.9 OF TOTAL SNOWFALL FOR THAT SAME TIME FRAME. I BELIEVE A COMPROMISED SOLUTION SHOULD WORK OUT THE BEST AND WE EXPECT A TOTAL SNOWFALL OF 3 TO 6 INCHES FROM AROUND MIDNIGHT TONIGHT THROUGH THE EARLY AFTERNOON HOURS MONDAY ROUGHLY ALONG AND NORTH OF A LINE FROM MKG TO ALMA. LIGHTER TOTAL SNOW ACCUMS ARE ANTICIPATED IN THAT TIME FRAME IN THE I-96 CORRIDOR BUFFER ZONE FROM GRR EAST WHERE SNOW COULD BE MIXED WITH SLEET AT TIMES TONIGHT. WE FELT THAT NO HEADLINES WERE NECESSARY AT THIS TIME FOR OUR CENTRAL AND NORTHERN CWA FOR TONIGHT/MONDAY MORNING SINCE SNOW TOTALS SHOULD STAY BELOW WARNING CRITERIA. I FELT THE DAY SHIFT COULD MAKE THE CALL ON A POTENTIAL SNOW ADVISORY HEADLINE FOR OUR NORTHERN CWA WHICH WILL PROBABLY BECOME NECESSARY FOR TONIGHT INTO MONDAY MORNING BASED ON 12Z GUIDANCE AND MODEL QPF TRENDS. COLDER AIR WILL CONTINUE TO ADVECT IN BEHIND THIS SYSTEM AND 850 MB TEMPS WILL FALL TO AROUND -12 C MONDAY NIGHT AND -14 TO -16 C TUESDAY. THIS WILL SET THE STAGE FOR LAKE EFFECT SNOW IN NW FLOW WITH POTENTIAL FOR SIGNIFICANT ACCUMS IN OUR FAVORED NW FLOW SNOW BELT REGIONS MONDAY NIGHT THROUGH TUESDAY. THEREFORE WE BUMPED POPS UP TO LIKELY FOR OUR WESTERN CWA FOR THAT TIME FRAME. .LONG TERM... EXTENDED PERIOD BEGINS TUESDAY NIGHT WITH LAKE EFFECT SNOW SHOWERS TAPERING OFF TO FLURRIES AND ENDING AS INVERSION HEIGHTS LOWER AND SFC HIGH BUILDS IN. THE SFC HIGH MOVES ACROSS ON WEDNESDAY PROVIDING A NICE WINTER DAY BUT A CLIPPER IS APPROACHING FROM THE NORTHWEST BY LATE THURSDAY INTO THURSDAY NIGHT. THERE IS ALSO A SURGE OF MOISTURE FROM THE SOUTHERN STREAM AT THAT TIME BUT IT APPEARS THESE TWO SYSTEMS WILL NOT PHASE...AT LEAST NOT UNTIL THEY ARE EAST OF THE GREAT LAKES. WILL KEEP THE CHANCE POPS GOING THROUGH THE END OF THE PERIOD AS ECMWF AND GFS BOTH SHOW A SHOT OF COLD AIR ARRIVING FRIDAY AND LAKE EFFECT SNOW SHOWERS A DEFINITE POSSIBILITY. && .GRR WATCHES/WARNINGS/ADVISORIES...WINTER WEATHER ADVISORY THROUGH 4 PM THIS AFTERNOON FOR THE SRN HALF OF THE GRR CWFA. WINTER STORM WATCH FROM 8 PM THIS EVENING THROUGH NOON MONDAY FOR ALLEGAN... BARRY... EATON... INGHAM... VAN BUREN... KALAMAZOO... CALHOUN AND JACKSON COUNTIES. && LAURENS OSTUNO
