The episode as NWS ILN wrote it up.

SHORT TERM /TODAY THROUGH THURSDAY/...
GFS AND NAM CONTINUING TO SHOW GOOD RUN TO RUN CONTINUITY WITH TRACK
OF CLIPPER SYSTEM FOR THIS AFTERNOON AND THIS EVENING. THE NAM HAS
SPED UP SOME AND IS NOW A LITTLE MORE IN LINE WITH THE FASTER GFS
AND WILL CONTINUE TO TREND THE FORECAST TOWARD THIS FASTER SOLUTION.
IT STILL LOOKS LIKE A 6 TO POSSIBLY 9 HOUR PERIOD OF PRETTY GOOD
ISENTROPIC LIFT WITH THIS SYSTEM. AVERAGE MIXING RATIOS DURING
THE PERIOD RANGE FROM 1.8 ACROSS OUR NORTH TO 3.4 FOR OUR FAR
SOUTHWEST. USING A MODIFIED GARCIA TECHNIQUE YIELDS MAX SNOW AMOUNTS
OF ABOUT 2.5 IN THE FAR NORTH TO ABOUT 5.5 INCHES IN THE SOUTH. IN
ADDITION...BOTH THE NAM AND GFS ARE SHOWING A LITTLE BETTER QPFS
THIS RUN WITH EACH INDICATING SOME AREAS OF 0.5 INCH LIQUID ACROSS
OUR SOUTH.
WILD CARD REMAINS THE LIQUID TO SNOW RATIO THAT WE WILL END UP BEING
ABLE TO ACHIEVE. USING A 20 TO 1 RATIO FOR TEMPS IN THE 10 TO 20
DEGREE RANGE AND A 15 TO 1 RATIO FOR 20 TO 28 DEGREES...YIELD SOME
PRETTY HIGH SNOWFALL TOTALS FOR PARTS OF OUR SOUTH (IN EXCESS OF 7
INCHES). GIVEN THE SPEED OF THE SYSTEM...WILL NOT GO THAT HIGH BUT
WE WILL NUDGE UP TO A STORM TOTAL OF 4 TO 6 INCHES FOR AREAS ALONG
AND SOUTH OF THE OHIO RIVER. WILL KEEP 3 TO 5 INCHES GOING FOR THE
REMAINDER OF THE WARNING AREA. ELSEWHERE...WILL HAVE A TIER OR TWO
OF COUNTIES BORDERING THE WARNING AT 2 TO 4 INCHES WITH 1 TO 3
INCHES ACROSS THE FAR NORTH.
ONLY CHANGES PLANNED TO THE HEADLINES WILL BE TO MOVE THE START TIME
OF THE SNOW ADVISORY AND THE HEAVY SNOW WARNING FOR THE SOUTHEAST UP
TO 1 PM.
SYSTEM PULLS OUT QUICKLY THIS EVENING AND WOULD NOT BE SURPRISED IF
SNOW IS PRETTY MUCH OVER BY ABOUT MIDNIGHT. ELONGATED SURFACE HIGH
WILL THEN BUILD DOWN INTO THE AREA...KEEPING COLD TEMPERATURES IN
PLACE THROUGH THE REST OF THE SHORT TERM. A WEAK VORT PASSES QUICKLY
TO OUR SOUTH WEDNESDAY NIGHT INTO THURSDAY MORNING AND THIS MAY BE
ENOUGH TO PRODUCE A FEW FLURRIES ACROSS OUR FAR SOUTH.
WINDS SHOULD REMAIN FAIRLY LIGHT THROUGH THIS MORNING SO WIND CHILLS
SHOULD NOT BE THAT MUCH OF A FACTOR. HOWEVER...GIVEN VERY COLD TEMPS
IN PLACE CURRENTLY...WILL GO AHEAD AND JUST KEEP THE WIND CHILL
ADVISORY UP FOR THE NORTH THROUGH THIS MORNING.
PREV DISCUSSION...
/ISSUED 441 PM EST MON FEB 5 2007/

STRONG H5 S/W DROPS THRU THE LAKES FRI WITH AN A REINFORCING SHORT

EFFECT SHSN FRI AFTN INTO FRI EVE. SCT SHSN WILL LINGER INTO SAT AS
