What happened

The episode as NWS GRR wrote it up.

Moderate to heavy lake effect snow redeveloped during the evening hours of the 25th and continued through the afternoon hours of the 27th. At least eight inches of snow fell across the area and many locations across Ottawa, Kent, Allegan, Barry, and Van Buren counties received well in excess of a foot. The highest snowfall totals were reported in Grandville (Kent county) where 26" of snow fell, and in Allegan (Allegan county), where 25.2 inches of snow fell. This snow added to significant snow that had already fallen since the 23rd. Up to 15 inches of snow fell in Grandville in less than 24 hours and around 24 to 25 inches of snow fell in a band from Grandville southwest to Allegan.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
335 PM EST TUE DEC 25 2001

MAIN FORECAST PROBLEM IN THE NEAR TERM CONTINUES TO BE PINNING DOWN
DETAILS OF LES EACH PERIOD. LAPS MODEL SOUNDINGS SHOWING SOME DRYING
AND DIRECTIONAL SHEAR IN THE BOUNDARY LAYER TODAY AS LES HAS HAD
DIFFICULT TIME GETTING ORGANIZED. FOR TONIGHT...MODEL SOUNDINGS SHOW
IMPROVING CONDITIONS FOR THE ENHANCEMENT OF LES AS MID LEVEL
SHORTWAVE TROUGH MOVES THROUGH. MSAS SFC PRESSURE SHOWS A SFC
REFLECTION OF THIS TROUGH AND THE VIS SAT LOOP SHOWS WHAT APPEARS TO
BE MID-LEVEL VORT MAX MOVING ACROSS NORTHERN ILLINOIS ATTM. IN
FACT...THIS FEATURE IS CURRENTLY PRODUCING LIGHT SNOW IN THAT AREA.

FORECAST REASONING IS THAT THE TROUGH PASSAGE WILL SEE INVERSION
HEIGHTS RISING CONSIDERABLY OVERNIGHT...AS WELL AS LOW LEVEL
CONVERGENCE ZONE FORMING AND INTENSIFYING IN SW FLOW AHEAD OF THE
TROUGH AXIS THIS EVENING INTO THE OVERNIGHT PERIOD. MESO-ETA SHOWS
BEST SFC CONVERGENCE WILL BE FROM ALLEGAN/OTTAWA COUNTIES AND INTO
KENT AND MUSKEGON COUNTIES. WILL GO WITH A LES WARNING IN THIS AREA
AND BUFFER THE SURROUNDING COUNTIES WITH A LES ADVISORY. LOW TEMPS
WILL BE TRICKY AS WELL...AS SW FLOW WILL BRING COLDER AIR TO
SOUTHERN INTERIOR ZONES.  WILL GO 10 TO 15 IN THAT AREA...15 TO 20
NORTHERN INTERIOR...AND NEAR 20 FOR THE COASTAL ZONES.

SOUNDINGS STILL SHOWING DEEP MOISTURE AND INVERSION HEIGHTS AROUND
7-8 KFT RIGHT THROUGH WED EVENING. WILL KEEP THE WARNINGS/ADV GOING
THROUGH WED AFTERNOON...ALTHOUGH FLOW APPEARS TO VEER MORE TO THE NW
DURING WED AFTERNOON. WILL LET LATER SHIFTS TWEAK THE WARNING/ADV
FOR THE DAY ON WED. AXIS OF MID LEVEL THERMAL TROUGH PASSES THROUGH
WEDNESDAY AFTERNOON AND INVERSION HEIGHTS LOWER A BIT WEDNESDAY
NIGHT...BUT BUT DEEP MOISTURE IS IN PLACE AS WELL AS STRONG LOW
LEVEL CAA AND CYCLONIC FLOW...SO WILL KEEP CAT POPS FOR THE WESTERN
HALF OF THE CWA...LIKELY EASTERN HALF. WILL CONTINUE THIS TREND
RIGHT THURSDAY NIGHT...AS SYNOPTIC SITUATION REMAINS FAVORABLE FOR
CONTINUATION OF LES.

WILL ALSO CONTINUE WITH TEMPS IN THE INERIOR ZONES SEVERAL DEGREES
COLDER THAN COASTAL ZONES.

OSTUNO

EXTENDED FORECAST
UPPER LEVEL LOW CURRENTLY OVER THE THE GREAT LAKES REGION BEGINS TO
REDEVELOP TO THE NORTHEAST BY THE WEEKEND.  MEDIUM RANGE MODELS HAVE
BEEN CONSISTENT WITH THIS FOR SEVERAL RUNS NOW AND SUPPORT THIS
TRANSITION. EVEN AS THE UPPER LOW REFORMS LOWER MICHIGAN WILL REMAIN
UNDER A MOIST WEST/NORTHWEST FLOW.  FOR THE REST OF THE WEEK INTO
THE WEEKEND LOW LEVEL WEST/NORTHWEST FLOW WILL CONTINUE WITH A
SERIES OF SHORTWAVES ROTATING AROUND UPPER LEVEL LOW.  DECENT LOW
LEVEL MOISTURE REMAINS TRAPPED BENEATH UPPER LOW AND WITH SHORTWAVES
REINFORCING LOW LEVEL COLD AIR ACROSS THE REGION IT LOOKS LIKE LAKE
EFFECT SNOW SHOWERS WILL CONTINUE THROUGH THE WEEKEND. THE
OPERATIONAL MRF IS FINALLY HINTING AT A LET UP IN THE PRECIPITATION
EARLY NEXT WEEK AS A CANADIAN HIGH DROPS INTO THE CENTRAL PLAINS
BRINGING DRIER AIR TO THE GREAT LAKES REGION. AS THIS HIGH DROPS S
THROUGH THE PLAINS MRF INDICATES WEAK WARM ADVECTION WILL BEGIN IN
THE GREAT LAKES REGION DIMINISHING LAKE EFFECT THREAT. HOWEVER...
LITTLE CONFIDENCE IN TIMING/DETAILS THIS FAR OUT AND ENSEMBLES
DIFFER QUITE A BIT ON TIMING SO WILL CONTINUE CHANCE OF SNOW
SHOWERS INTO TUESDAY.  WILL LEAVE GOING EXTENDED ESSENTIALLY
UNCHANGED WITH SNOW SHOWERS EACH DAY THROUGH THE WEEKEND.
