What happened

The episode as NWS LSX wrote it up.

A major winter storm hit Western and Southern Illinois from November 30 through December 1, 2006. Up to a foot of snow fell across West Central Illinois while up to an inch of ice and sleet accumulated across Southwest Illinois, including the St. Louis area. Up to 300,000 customers lost electric service across Southwest and Southern Illinois due to downed power lines. In some areas it took a week to get the power restored. Many rural schools were closed for several days due to slick roads and power outages. Numerous buildings and automobiles were damaged by fallings trees and tree limbs. Damages will likely approach $100 million. Following is a short summary of how the storm affected various counties. Bond County: A tree fell on a car causing minor injuries to the driver. At least half of Greenville, IL lost power during the storm. Madison County: At least 75% of Edwardsville, IL lost power due to the storm. Numerous roofs and automobiles were damaged by falling tree limbs. There was one death due to an auto accident and another person died from carbon monoxide poisoning. Fumes from a generator running in a garage entered the home, killing one resident and seriously injuring another. Macoupin County: Emergency Management officials estimated that at least 40,000 of the 50,000 residents lost power during the storm. The southern 1/4 of the county was especially hard hit with most towns from Brighton to Bunker Hill to Staunton losing virtually all power. Monroe County: 142 residents of a nursing home had to be moved to another facility due to power problems. The small town of Maeystown lost all power and 66% of Waterloo lost power. Montgomery County: Emergency Management officials reported that 1 in 4 residents lost power from the storm. Pike County: One person was injured in an auto accident during the storm. The County Health Department in Pittsfield had to be closed because of a sagging roof the result of over a foot of snow. St. Clair County: It was reported that 70% of the town of Mascoutah lost power from the storm. At least half of the residents in the Millstadt/Smithson area lost power. Roofs and autos were damaged due to falling tree limbs across East St. Louis, Alton, and Cahokia. One person was injured in an auto accident in Alton.

.DISCUSSION...
...MAJOR WINTER STORM WILL AFFECT REGION THROUGH FRIDAY MORNING...

THE 12Z SHORT-TERM MODELS (THRU FRIDAY AFTERNOON)...HAVE COME INTO
BETTER AGREEMENT...ESPECIALLY THE NAM AND GFS...ON HANDLING OF A
MAJOR WINTER STORM TO AFFECT THE AREA...THE FIRST OF THE SEASON.

STARTING WITH TONIGHT...THE MODELS HAVE NOT CORRECTLY ANTICIPATED
THE FORWARD SPEED OF THE ARCTIC CDFNT NOW MOVING THRU OUR AREA...
ROUGHLY ALONG A NEAR KSPI-THRU ST CHARLES COUNTY MO-JUST W OF
KVIH-JUST SE OF KSGF. THE /WEIGHT/ OF THE CD AIR IS FORCING IT
FURTHER S...EVEN WITH STRONG MID LEVEL FLOW TRYING TO TIE IT UP
AHEAD OF A DEVELOPING WAVE OVER ERN OK. WENT AGGRESSIVE AND COLDER
THAN MOS AND MODELS TO ACCOUNT FOR SHARP DROP IN TEMPS BEHIND
FRONT...WITH KIRK ALREADY AT 30F VAST MAJORITY OF PCPN NOW
DEVELOPING ALG-BEHIND CDFNT OVER SHALLOW ARCTIC AIR IN REGION OF
STRONG RIGHT ENTRANCE REGION LIFT OF H300 JET AND NOSE OF DEVELOPING
H850 JET. THIS STRONG REGION OF LIFT COUPLED WITH FRONTOGENETICAL
FORCING AT MID LEVELS TO GRADUALLY SHIFT FROM THE NWRN HALF OF THE
FA THIS EVENING TO THE SERN HALF LATER TONIGHT. ABNORMALLY HI PWATS
FOR LATE NOVEMBER AND POTENTIAL FOR TRAINING ECHOES AND THUNDER
(ALREADY EXISTING OVER ERN OK THRU NERN MO)...WILL LEAD TO ENHANCED
PCPN TOTALS AND HAVE MENTIONED HEAVY RAINFALL POTENTIAL IN FORECAST.
AS COLD AIR SLOWLY SEEPS INTO THE NWRN FA TONIGHT...WILL SEE RAIN
CHANGE TO FZRA IN THE NWRN THIRD BY LATE TONIGHT.

HEADING INTO THURSDAY...FRONTOGENETICAL PCPN WILL SHIFT TO SERN HALF
OF THE FA AND THEN FADE BY AFTERNOON...ALLOWING FOR A BREAK FOR MOST
AREAS AT SOME POINT FROM LATE MORNING THRU AFTERNOON. BUT NOT
ENTIRELY...AS FZDZ SHOULD BE PREVALENT IN AREAS WITH SUB-FRZG SFC
TEMPS. LOOK FOR 32F ISOTHERM TO PUSH THRU THE STL METRO AREA DURING
LATE MORNING AND EARLY AFTERNOON FROM NW-SE...AND THEN INTO THE SERN
HALF OF THE FA DURING THE AFTERNOON. LOOKING AT SIGNIFICANT ICING
EVENT THRU THURSDAY AFTERNOON...ESPECIALLY IN STRIPE FROM
KVIH-KSTL-K3LF WHERE THIS AREA WILL BE SLOW TO CLEAR OUT FROM
FRONTOGENETICAL PCPN...YET COLD AIR WILL UNDERCUT AS EXPECTED.

FOR THURSDAY NIGHT TIL THE STORM/S CONCLUSION ON FRIDAY MORNING...
MAIN HEAVY SNOW THREAT WILL BE FROM THIS SYSTEM. MODELS HAVE ALL
COME INTO EXCELLENT AGREEMENT ON THE STRENGTH AND TRACK OF THIS
STRONG IMPULSE...NOW EXPECTED TO FORM A CLOSED CIRCULATION BY LATE
THURSDAY AFTERNOON AS H500 CENTER TRACKS JUST S AND E OF KSTL LATE
THURSDAY NIGHT THEN PULLS AWAY FRIDAY MORNING. H700 LO...WHICH HELPS
TO DETERMINE HEAVY PCPN TRACK JUST TO THE LEFT...IS VERY CLOSE TO
THE H500 TRACK. H850 LO...WHICH HELPS TO DETERMINE MAINTENANCE OF
WARM WEDGE OF AIR ALOFT...NOT EXPECTED TO TRACK PAST OUR AREA TIL
LATE THURSDAY EVENING...THEREBY EXPECTING TO KEEP MIXED WINTRY PCPN
IN PLACE FOR THE STL METRO AREA TIL THIS TIME. FURTHER N AND
W...WHEN PCPN RESUMES AROUND SUNSET...SHOULD FALL AS ALL SNOW ALMOST
FROM THE ONSET...AND HEAVY AT TIMES. S AND E OF KSTL...PRESENCE OF
32F ISOTHERM WILL KEEP P-TYPE CALL TOUGH TO A RANGE OF
POSSIBILITIES. LOOKING FOR A STRIPE OF HEAVY SNOW FROM JUST E OF
KCOU-TROY-BOWLING GREEN-PITTSFIELD IL...WHERE NOT ONLY MOST IF NOT
ALL PCPN WILL FALL AS SNOW...BUT ALSO POTENTIAL FOR BANDED SNOW
STRUCTURE AND/OR THUNDERSNOW SUPPORTING MUCH HIGHER SNOWFALL RATES.
FOR NOW HAVE BUMPED UP AMOUNTS TO CLOSE TO A FOOT IN THIS
AREA...TAPERING TO JUST A FEW INCHES IN SERN MO/SRN IL. AS A
RESULT...ALL OF WATCH WILL BE CONVERTED TO A WARNING WITH THIS
PACKAGE EXCEPT IN THE SE EXTREMITY OF THE FA...WHERE LATER ARRIVAL
OF SUB FREEZING TEMPS AND PERSISTENT WARM WEDGE WILL LOWER ICE AND
SNOW AMOUNTS.

TES

FOR PDS STARTING AT 00Z SAT...AT BEGINNING OF THIS PD...MDLS SEEM TO
AGREE RATHER WELL. HOWEVER...MDLS DIVERGE BEGINNING SOON AFT. GFS IS
STGR WITH SRY S/W AT 12Z TUES. GIVEN THE INCONSISTENCIES WITH THE
GFS...AM LEANING TWD AN ECMWF SOLN FOR LOCATION...TIMING OF SYNOPTIC
FEATURES.

ENTR EXTD IS DRY ATTM. THEREFORE...FCST PROBLEM BCMS TEMPS. HAVE
TRENDED TEMPS DOWN IN EXTD PD...ESP FOR SAT. SAT MRNG LOWS SHUD BE
ALLOWED TO FALL INTO LOW TEENS WITH POSS SN PACK AND CLR SKIES. AFT
SAT...TEMPS WILL NOT HAVE A CHC TO REBOUND MUCH. A STG SFC RIDGE
WILL BE IN PLACE WITH GENERALLY A NLY FLOW IN PLACE. SLY FLOW MAY
RETURN FOR A WHILE LATE MON BEFORE ANOTHER CDFNT MVS THRU CWA LATE
TUES. CONFIDENCE IN A FROPA ON TUES IS RATHER LOW DUE TO LACK OF UPR
LVL SUPPORT OF FEATURE. THINKING IS THAT CDFNT WILL STALL N OF CWA
DURING THIS TIME PD...ALLOWING SOME WWA. HOWEVER...AMT OF WRMG IS
UNCERTAIN GIVEN POSSIBLE CLD CVR.
