Winter Storm in Wisconsin, December 23 to 24, 2007

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GREEN BAY WI
857 PM CST SAT DEC 22 2007

.UPDATE...INTENSE SHRTWV EJECTING OUT OF THE SRN PLAINS WAS VERY
IMPRESSIVE ON STLT IMAGERY. SFC LOW NOW DEEPENING NEAR STL...WITH
GREATEST 3 HR PRESSURE FALLS ACRS SRN/CEN IL...NWD INTO E-C WI.

SFC FRONT AND RN/SN LINE STILL MAKING SOME EWD PROGRESS...BUT WITH
LOW-LEVEL WINDS STARTING TO BACK ARND IN ADVANCE OF THE EJECTING
UPR SYSTEM...THINK PROGRESS WL COME TO A HALT SOON. 00Z RUC/NAM
CRITICAL THICKNESS VERY SIMILAR...AND KEEP LIQUID PCPN IN THE FAR
E/NE THROUGH 12Z. BASED ON THAT...WL DELAY THE START TIMES OF THE
HEADLINES IN THE E A BIT.

WL ALSO GO IN AND TWEAK THE GRIDS/FCST TO HAVE A BIT OF A LULL IN
THE PCPN OVER E-C WI LATER TOMORROW MORNING AS THERE SHOULD BE A
LULL IN THE LIFT IMMEDIATELY AFTER THE MAIN SHRTWV LIFTS THROUGH.
THEN WL BRING A BIT MORE SNOW THROUGH THAT AREA LATER SUN AND INTO
SUN NGT AS REMNANTS OF COMMA HEAD PIVOT ACRS THE RGN.

WARNING ENDING TIME MAY NEED TO BE EXTENDED...BUT WL LEAVE THAT
FOR THE MID SHIFT. AMNTS IN THE WARNING AREA STILL LOOK PRETTY GOOD.

CODING FOR NEW HEADLINES IS BELOW. WL GET UPDATED PRODUCT SUITE
OUT ASAP...BUT WITH LOTS OF LITTLE CHGS IT MAY TAKE A 30-45
MINUTES TO GET EVERYTHING PUT TOGETHER AND SHIPPED OUT.

.PREV DISCUSSION...ISSUED AT 631 PM CST SAT DEC 22 2007...

UPDATE...PCPN OVERSPREADING THE AREA FM THE S. THAT THAT WON/T
WIPE OUT THE FOG...IT SHOULD GENERATE ENOUGH MIXING TO GET VSBYS
ABV DENSE FG CRITERIA. PLAN TO LET THE ADVISORY EXPIRE AS
SCHEDULED AT 700 PM.

OVERALL IMPRESSION IS THAT THE COLD FRONT AND RN/SN LINE HAVE MADE
A BIT MORE EWD PROGRESS THAN DEPICTED ON THE MODELS. CRITICAL
THICKNESS PLOTS OFF THE RUC13 INDICATE COLD AIR WL EDGE EWD FOR A
FEW HOURS YET THEN THE RN/SN LINE WL PROBABLY COME TO A HALT AS
WAA INCREASES AS THE SFC LOW DEEPENS NNEWD TOWARD ERN WI. THAT
FITS VERY WELL WITH THE START TIME OF THE WARNING IN THE CURRENT
FCST. RADAR MOSAIC LOOKS VERY OMINOUS FOR CENTRAL WI. WL NEED TO
MONITOR THE RATE OF ACCUMULATION VERY CLOSELY ONCE THE SNOW GETS
GOING IN THE NEXT COUPLE HRS.

THE RUC/NAM/GFS KEPT PCPN ALL RN IN FAR ERN WI UNTIL MORNING...
THEN DID NOT HAVE MUCH PCPN ONCE THE CHANGEOVER OCCURS. THEY
INDICATED THE BEST SN IN E-C WI WOULD NOT COME UNTIL LATER SUN
INTO SUN NGT WHEN THE REMNANTS OF THE COMMA HEAD SWING SE ACRS THE
AREA. AM NOT READY TO START MESSING WITH THE FCST FOR E-C WI AS AM
STILL CONCERNED THAT A QUICKER CHANGEOVER COULD OCCUR WHEN CORE OF
INTENSE LIFT COMES ACRS LATE TNGT.

WL COME OUT WITH FCST UPDATE TO DROP DENSE FG ADVISORY JUST AFTER
700 PM.

DISCUSSION ISSUED AT 228 PM CST SAT DEC 22 2007...

SHORT TERM...TONIGHT AND SUNDAY...

EARLY AFTN SATELLITE CLEARLY SHOWS THE TWO SHORTWV TROFS (ONE OVR
ND AND THE OTHER ACRS OK) HEADING FOR PHASING ACRS MIDWEST.
FORECAST IS ON TRACK FOR SIGNIFICANT WINTER STORM WITH HEAVY SNOW
AND STRONG WINDS AS SFC LOW RAPIDLY DEEPENS OVR WRN LK MICH.

PCPN RAPIDLY EXPANDING AND MOVG NE FM KS/MO/IA. QUESTION FOR FCST
AREA IS WHEN THE CHANGEOVER WL OCCUR. 1000-850 MB THICKNESS (1300
M) SEEMS TO BE WORKING AS A GOOD RN/SN LINE AND WL FOLLOW ACRS
FCST AREA. CHANGEOVER TO SNOW IN THE FAR E EXPECTED BY ABOUT
12Z...15Z IN DOOR CO. HOWEVER...SMALL CHANGES NOTED IN 12Z/18Z
MODELS WITH LOW TRACK. THIS WILL HAVE IMPACT ON WHEN RAIN CHANGES
TO SNOW IN THE FAR EAST. QUICK CHANGEOVER EXPECTED...HOWEVER...AS
POLAR AIR STREAMS IN BEHIND DEEPENING LOW.

DENSE FOG STILL A CONCERN EARLY IN FCST AS SFC TROF MOVS ACRS
MOIST ATMOSPHERE AND WINDS STAY RELATIVELY LOW. WL CONTINUE DENSE
FOG ADVY ACRS SE HALF OF FCST AREA UNTIL AT LEAST 7 PM.

SOME TWEAKING TO PCPN TIMING (BOTH ONSET AND CHANGEOVER) MADE.
OTHERWISE...FEW ADJUSTMENTS REQUIRED.

LONG TERM...SUNDAY NGT THRU NXT SAT. MAIN FCST CHALLENGES INCLUDE:
WRAPPING UP INITIAL STORM SUN NGT INTO MON...AND TIMING OF PCPN FOR
A COUPLE NEW SYSTEMS NXT WEEK.

AN ACTIVE WEATHER PATN TO CONT AS A SERIES OF PAC STORMS DIVE SE
TOWARD THE SRN PLAINS AND THEN EJECT NE TOWARD THE GREAT LKS/OHIO
VALLEY RGNS. ONE SYSTEM TO IMPACT THE RGN WED INTO EARLY THU AND
ANOTHER (STRONGER) SYSTEM FOR LATE NXT WEEK. DESPITE SW FLOW
ALOFT...TEMPS FCST TO BE COLD ENUF SUCH THAT ANY PCPN THAT FALLS
WOULD BE ALL FROZEN.

INITIAL STORM TO MOV TOWARD THE ERN ONTARIO/WRN QUEBEC BORDER BY
12Z MON WITH SNOW GRADUALLY TAPERING OFF FROM SW TO NE ACROSS WI.
THE NE 1/2 OF THE FCST AREA WL STILL SEE ONE TO TWO INCHES OF ADDL
SNOW WITH LOCATIONS FARTHER SOUTH ONLY SEEING AN INCH OR LESS.
CONTEMPLATED EXTENDING THE HEADLINES TO 06Z...BUT FEEL HEAVIEST
SNOWS TO ALREADY HAVE LIFTED TO THE NORTH...DESPITE THE GUSTY WNDS
WHICH WL PERSIST THRU THE NGT. IF CONDITIONS WARRANT...WE COULD
ALWAYS ISSUE EITHER A BLOWING SNOW OR A SNOW/BLOWING SNOW ADVY
JUST FOR SUNDAY EVENING ONCE THE WARNING HEADLINES EXPIRE.

AS THE STORM CONTS TO PULL AWAY ON MON...CYCLONIC FLOW WL WEAKEN
AND THE PRES GRAD SLACKENS WITH HI PRES APPROACHING. WL NEED TO
CARRY A CHC OF SNOW SHWRS ACROSS N-CNTRL WI INTO MON MORNING AS LK
EFFECT IS PSBL. THIS APRS TO BE A MINOR EVENT AS 8H TEMPS ARE NOT
COLD (ABT -8C) AND WNDS BEGIN TO BACK MORE TO THE WEST BY MON
AFTERNOON. THE REST OF THE FCST AREA SHOULD REMAIN MOSTLY CLDY
WITH A FEW FLURRIES PASSING BY FROM TIME TO TIME. THE CLDS WL HELP
HOLD TEMPS DOWN AND HAVE STAYED NEAR THE COOLER MAV GUID FOR MAX
TEMPS ON MON.

THE HI PRES BUILDS INTO THE WRN GREAT LKS MON NGT AND SHOULD BRING
AT LEAST PARTLY CLDY SKIES INTO NE WI. WNDS ARE EXPECTED TO
DIMINISH ENUF TO ALLOW TEMPS TO DROP OF PRETTY WELL. PREFER TO
UNDERCUT GUID BY SEVERAL DEGS TO COMPENSATE FOR THE FRESH SNOW
CVR. HI PRES PUSHES OFF TO THE EAST BY TUE ALLOWING WNDS TO BACK
SOUTH AND KEEP ADVECTING WARMER AIR INTO NE WI. TEHRE MAY BE SOME
INCREASE IN CLDS TUE AFTERNOON OVR N-CNTRL WI AS A CDFNT MOVS INTO
THE UPR MIDWEST...HOWEVER DRY CONDITIONS WL PREVAIL. MAX TEMPS WL
BE ABT 5 DEGS ABV NORMAL ON TUE.

CDFNT EASES ACROSS WI LATE TUE NGT INTO WED MORNING BUT LACK OF
MSTR WITH FAIRLY WEAK DYNAMICS WOULD POINT TO A LIMITED PCPN
THREAT. PREFER TO DOWNPLAY SNOW POTENTIAL AND ONLY GO WITH SLGT
CHC WORDING FOR NOW. DESPITE THE FROPA...TEMPS STILL RELATIVELY
MILD FOR THIS TIME OF YEAR (8H TEMPS BETWEEN -3 AND -8C). HAVE
RAISED MAX TEMPS FOR WED A COUPLE OF DEGS. A BETTER CHC OF SNOW
ARRIVES LATE WED INTO WED NGT AS A WEAKENING SRN STREAM SHRTWV
TROF LIFTS NE FROM THE OZARKS TO THE SRN GREAT LKS. WHILE DYNAMICS
AND LIFT ARE NOT OVERWHELMING...ENUF FORCING AND MSTR WL BE PLACE
TO WARRANT CHC POPS ACROSS NE WI. PCPN CHCS WL THEN LINGER INTO
THU AS THE SHRTWV TROF MOVS INTO THE ERN GREAT LKS/SE ONTARIO AND
MSTR IS THROWN BACK INTO THE WRN GREAT LKS. ANY SNOW ACCUMULATIONS
WITH THIS SYSTEM APR TO BE VERY MINOR.

AS ONE SYSTEM DEPARTS...ATTN TURNS BACK TOWARD THE SRN PLAINS
WHERE THE NXT SYSTEM WL BE ORGANIZING ITSELF FOR FRI. MDLS ARE IN
DISPUTE AS TO THE TIMING OF THIS SYSTEM WITH GFS MUCH FASTER THAN
THE ECMWF. IT SHOULD BE NOTED THO THAT THE 12Z ECMWF HAS SPED UP A
BIT FROM ITS PREV 00Z RUN. A 60 KT LOW LVL JET WL PRECEDE THIS STORM...
THUS PLENTY OF MSTR SHOULD BE IN PLACE. WAY TOO MUCH UNCERTAINTY
AS THIS TIME TO DETERMINE SNOW TOTALS LET ALONE WHICH DAY (FRI OR
SAT) THAT NE WI WOULD BE IMPACTED. NEEDLESS TO SAY...THIS ONE WL
HAVE TO BE WATCHED CLOSELY IN THE COMING DAYS.

AVIATION...AREAS VLIFR AND LIFR WITH FOG THIS EVENING...ESP IN
EAST-CNTRL WI.  WIDESPREAD IFR CIGS/VSBYS WITH XPCTD SNOW AFTER
COLD FRONT MOVES THROUGH TONIGHT. HEAVY SNOW AND STRONG WEST WINDS
WILL DEVELOP BEHIND THE FRONT AS SFC LOW PRES MOVS N OVR WRN LK
MICH.

MARINE...GALE WARNINGS ARE IN EFFECT SUNDAY INTO SUNDAY
NIGHT. POWERFUL WEST WINDS WILL DEVELOP AS A LOW PRESSURE SYSTEM
LIFTS NORTH OF THE RGN SUNDAY INTO SUNDAY NIGHT.
