What happened

The episode as NWS PAH wrote it up.

A long-lasting sleet storm affected southern Illinois. The precipitation was almost all sleet south of the Marion/Carbondale area, where an inch or two was reported. Along and north of a Carbondale to Harrisburg line, there was more snow, with total accumulations of sleet and snow in the 3 to 6 inch range. Specific reports included: 6 inches at Pinckneyville in Perry County, 5.5 inches near Mount Carmel in Wabash County, 4.5 inches at West Frankfort in Franklin County, 4 inches at Carbondale, and 2.4 inches at Harrisburg in Saline County. The storm occurred on the Presidents Day weekend. Most schools and businesses scheduled to be open on Presidents Day were closed. Franklin County officials reported about 25 accidents in that county alone, none of which involved injuries.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
239 PM CST SAT FEB 15 2003

CHALLENGE THIS PACKAGE IS WINTER WEATHER FOR TONIGHT AND SUNDAY.

ANALYSIS OF THE 15/12Z UPPER AIR MAPS SHOWED 85H AND 7H LOWS NEAR
KMCI. AN ASSOCIATED 85H AND 7H WARM FRONT EXTENDED EAST INTO CENTRAL
IL/IN. AT THE SURFACE AT 15Z LOW PRESSURE WAS OVER NORTHCENTRAL AR.
A COLD FRONT EXTENDED SOUTHWEST OF THIS LOW INTO EASTERN TEXAS. WHAT
HAD BEEN A WARM FRONT EXTENDING EAST OF THIS LOW...HAS NOW
TRANSITIONED INTO A COLD FRONT AND WAS POSITIONED NEAR THE AR/MO AND
KY/TN BORDERS.

THROUGH SUNDAY AFTERNOON THE NGM/ETA TRACK THE 85H LOW INTO WESTERN
TN. THE GFS TAKES A SOMEWHAT FURTHER EAST COURSE THROUGH CENTRAL KY
AND THEN EASTERN TN BY SUNDAY AFTERNOON. GIVEN THIS PATTERN THE
NGM/ETA KEEP THE SURGE OF WARMER 85H AIR OVERRIDING THE SUB-FREEZING
SURFACE CONDITIONS FOR A LONGER PERIOD OF TIME...SPECIFICALLY +2 TO
+6 C AT NOON SUNDAY COMPARED TO 0 TO -4 C. THE 15/18Z FORECAST OF
THESE THREE MODELS SHOWED LITTLE DIFFERENCE CONCERNING THE PATH OF
THE 85H AND SURFACE LOW...SO A COMPARISON TO REALTIME DATA ISN/T
HELPING IN PICKING A FAVORITE MODEL. AS SUCH...WILL GO WITH
PERSISTENCE AND FAVOR THE PREVIOUS SELECTION OF THE MORE SIMILAR
NGM/ETA SOLUTION.

15/15Z MESO-ETA FORECAST SOUNDINGS FOR ACROSS THE AREA STILL
SUGGEST A FREEZING RAIN EVENT ACROSS THE AREA. NORTHERN AREAS MAY
SEE A GRADUAL TRANSITION TO IP AND THEN TO LIGHT SNOW DURING THE DAY
TOMORROW. 15/15Z MESO QPF VALUES SUGGESTED AN INCREASE IN PRECIP
TONIGHT INTO SUNDAY AS THE 85H LOW PASSES OVERHEAD. TOTAL QPF
NUMBERS ACROSS SOUTHERN ILLINOIS AND WESTERN KENTUCKY PEAKED AROUND
0.40-0.50 INCHES WITH THE CRITICAL 0.25 VALUES ALONG THE WESTERN AND
EASTERN EDGES OF THE WARNING AREA.

AS THE MID AND UPPER LEVELS DRY OUT LATE SUNDAY NIGHT...THE EVENT
MAY END AS LIGHT FREEZING DRIZZLE.

HEADING INTO MONDAY WE LOOK TO STAY CLOUDY AS LOW LEVEL MOISTURE ON
THE BACKSIDE OF THE EXITING TROUGH REMAINS IN PLACE. TOO EARLY TO
MENTION DZ/FRDZ BUT IT IS SOMETHING TO WATCH. ETA HAS THE AREA
CLEARING BY TUESDAY MORNING. GUIDANCE HAS BEEN FAST TO CLEAR SKIES
ALL WINTER. AS SUCH WILL DELAY THIS UNTIL TUESDAY EVENING AND
UNDERCUT HIGHS.

FROM WEDNESDAY ONWARD SIGNIFICANT MODEL VARIATIONS ARE APPARENT. THE
15/00Z GFS SUGGEST IN QUICKLY RACING A SHORTWAVE TROUGH ACROSS THE
AREA ON WEDNESDAY...WITH BRIEF UPPER LEVEL RIDGING ON
THURSDAY...FOLLOWED BY A SIGNIFICANT UPPER LEVEL LOW CHARGING ACROSS
THE SOUTHERN PLAIN STATES FRIDAY...AND OVER THE FA BY SATURDAY.

THE 14/12Z ECMWF SOLUTION SUGGEST THE WEDNESDAY SHORTWAVE WON/T BE
AS PROGRESSIVE...AND ACTUALLY HELP CAUSE SOME POSITIVE INTERFERENCE
AND HELP AMPLIFY A SECOND SHORTWAVE TROUGH SPINNING ALONG THE
PACIFIC NORTHWEST COAST /THE ONE THE GFS SUGGESTED WOULD BE DISTINCT
FROM THE FIRST/. THIS RESULTANT LONGER WAVE TROUGH BECOMES ORIENTED
FROM THE CENTRAL ROCKIES SOUTHWEST TO OFF THE SOUTHERN CALIFORNIA
COAST. THIS WAVE EJECTS SLOWER THAN THE GFS SOLUTION OF WHAT IT
SHOWS AS A SECOND WAVE.

THE 15/00Z CANADIAN SOLUTION SEEMS TO BE SOMEWHERE IN THE MIDDLE OF
THE FIRST TWO. ITS SOLUTION IS SIMILAR TO THE ECMWF IN THAT IT ISN/T
AS PROGRESSIVE WITH THE FIRST SHORTWAVE TROUGH...BUT IT IS A LITTLE
SLOWER IN THE TIMING AS TO WHEN THE SECOND SHORTWAVE TROUGH WILL
MERGE WITH IT YIELDING POSITIVE INTERFERENCE IN THE CENTER OF CONUS.

WHAT IS SIMILAR WITH ALL THREE SOLUTIONS IS THAT THE SURFACE LOW
ASSOCIATED WITH THE FIRST SHORTWAVE TROUGH WILL PASS OVER OR NEAR
THE FA EITHER WEDNESDAY AFTERNOON OR WEDNESDAY NIGHT. GIVEN
THIS...WILL KEEP CHANCE POPS FOR SHOWERS BOTH WEDNESDAY AND
WEDNESDAY NIGHT. IF THE GFS IS RIGHT WE SHOULD HAVE A BREAK IN THE
WEATHER THURSDAY THEN A RETURN OF PRECIP...POSSIBLY
THUNDERSTORMS...FRIDAY INTO SATURDAY. IF THE ECMWF IS RIGHT A MUCH
COOLER AND DRIER FORECAST LEADING INTO THE WEEKEND IS ON TAP. IF THE
CANADIAN IS RIGHT...WEDNESDAY INTO THE WEEKEND WILL BE WET AND
MILD.

I WILL FAVOR THE ECMWF FOR TWO REASONS. FIRST...MY EXPERIENCE HAS
SHOWN IT TENDS TO OUT PERFORM THE GFS IN CASES WHERE THE GFS IS TOO
PROGRESSIVE IN EJECTING WEST COAST TROUGHS. SECOND...THE CANADIAN
SOLUTION OF THE THREE MODELS HAS HAD SLIGHTLY LOWER DAY5 ANOMALY
CORRELATION SCORES IN THE NORTHERN HEMISPHERE. AND ITS PERFORMANCE
IN THE SOUTHERN HEMISPHERE HAS SIGNIFICANTLY FALLEN OFF OVER THE
PAST FEW DAYS. ON THE OTHER HAND...THE ECMWF HAS INCREASED AS
RAPIDLY AS THE CANADIAN HAS FALLEN OFF.

THANKS SGF...ILX...LSX..IND...LVX FOR COOR/COLLABORATION.

.PAH...WINTER WEATHER ADVISORY TONIGHT THROUGH SUNDAY EVENING FOR
RIPLEY...CARTER...WAYNE AND BUTLER COUNTIES MO. WINTER STORM WARNING
TONIGHT INTO SUNDAY EVENING FOR THE REST OF SOUTHEAST MISSOURI...ALL
OF SOUTHERN ILLINOIS AND SOUTHWEST INDIANA AND WESTERN KENTUCKY
EXCEPT FOR MUHLENBERG...TODD...CHRISTIAN AND TRIGG COUNTIES.
