What happened

The episode as NWS PAH wrote it up.

A two-part winter storm dropped an average of 4 to 6 inches of heavy wet snow across southeast Missouri. The first round of snow occurred during the early morning and dropped 2 to 3 inches. The second round during the evening produced another 1 to 3 inches. Temperatures during the event were very close to freezing, and much of the accumulation was on grassy areas. Slushy roads were a concern, and numerous accidents occurred. No serious injuries were reported. Schools and businesses were closed due to the slippery road conditions. The snow was caused by an upper level disturbance moving east northeast from the Four Corners region. Some of the highest specific snowfall amounts included:6 inches at Lake Wappapello in Wayne County, 5.5 inches at Clearwater Dam in Wayne County, 5 inches at Marble Hill in Bollinger County, and 4 inches at Perryville in Perry County. The highest amounts were in the hilly terrain north and west of Poplar Bluff.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
120 AM CST THU FEB 6 2003

SNOW AMOUNTS REMAIN THE PRIMARY CONCERN FOR TODAY. MODELS ARE IN
VERY GOOD AGREEMENT WITH EACH OTHER...AND PRETTY CONSISTENT WITH
THEIR PREVIOUS RUNS. A 500 MB SHORTWAVE OVER THE FOUR CORNERS REGION
WILL DAMPEN OUT AS IT MOVES RAPIDLY EAST NORTHEAST TOWARD THE REGION
TODAY. A LARGE AREA OF PRECIPITATION ENTERING SOUTHEAST MISSOURI AND
SW KENTUCKY AT 06Z IS APPARENTLY RELATED TO STRONG WARM ADVECTION AT
700 MB. THIS PRECIPITATION WILL OVERSPREAD THE ENTIRE FORECAST AREA
BY AROUND 15Z. PRECIP TYPE WILL BE SNOW THIS MORNING AS INITIALLY
DRY LOWER LEVELS WET BULB DOWN INTO THE 20S. STATIONS IN NORTHERN
ARKANSAS AND WEST TENNESSEE HAVE OBSERVED TEMP DROPS AROUND 5
DEGREES WITH THE ONSET OF THE PRECIP. MODEL QPF PROGS AND UPSTREAM
OBSERVATIONS SUGGEST AN INCH OR SO WITH THIS WARM ADVECTION INDUCED
SNOW.

A DECREASE IN SNOW APPEARS LIKELY DURING THE MIDDAY HOURS. ETA TIME
HEIGHT CROSS SECTIONS INDICATE UPWARD VERTICAL MOTION WILL DIMINISH
BY AFTERNOON. QPF FIELDS SUPPORT THIS...SHOWING THE INITIAL BATCH OF
PRECIP DECREASING TODAY AS THE MID LEVEL WARM ADVECTION DIMINISHES.
WITH THE DECREASE IN PRECIP...SURFACE TEMPS WILL REACH THEIR HIGHS
NEAR OR SLIGHTLY ABOVE FREEZING.

ANOTHER BURST OF SNOW IS INDICATED LATE THIS AFTERNOON INTO EARLY
THIS EVENING ASSOCIATED WITH THE PASSAGE OF THE MID LEVEL TROUGH.
THE ETA SHOWS MORE IMPRESSIVE UPWARD MOTION FIELDS WITH THIS SECOND
BURST OF SNOW THAN WITH THIS MORNINGS. COULD EASILY SEE AN
ADDITIONAL TWO INCHES. SNOW TOTALS FOR THE EVENT SHOULD BE WELL
WITHIN THE RANGE FOR ADVISORY CRITERIA. AVN/ETA QPF FIELDS ARE IN
NEARLY PERFECT AGREEMENT...SHOWING AROUND ONE QUARTER INCH OF LIQUID
EQUIVALENT. HIGHEST AMOUNTS ARE SHOWN IN THE FAR WEST...WHERE
ISOLATED FOUR INCH AMOUNTS ARE CERTAINLY POSSIBLE IN THE FAVORED
HIGHER TERRAIN LOCATIONS NORTH AND WEST OF POPLAR BLUFF. PRECIP TYPE
SHOULD BE ALL SNOW...WITH THE EXCEPTION OF THE HOPKINSVILLE
AREA...WHERE THE 1000 TO 850 CRITICAL THICKNESS IS BRIEFLY REACHED
THIS AFTERNOON.

PRECIP WILL EXIT EASTERN PARTS OF THE FORECAST AREA AROUND
MIDNIGHT...FOLLOWED BY A SURGE OF COLDER AIR. ETA MODEL SOUNDINGS
INDICATE STRONG LOW LEVEL DRYING BY MID MORNING FRIDAY. DESPITE
PLENTY OF SUNSHINE FRIDAY...FRESH SNOW COVER AND BRISK NORTHWEST
WINDS WILL KEEP TEMPS FROM RISING MUCH. WILL GO A LITTLE BELOW MOS
GUIDANCE FOR HIGHS FRIDAY. A VERY COLD NIGHT IS IN STORE FOR FRIDAY
NIGHT WITH LOTS OF CLEAR SKY AND SNOW COVER.

SOME WARMING IS EXPECTED SATURDAY AS WINDS BECOME SOUTHWEST.
HOWEVER...GFS INDICATES THIS WARMING WILL BE SHORT LIVED AS THE
FORECAST AREA REMAINS IN A PERSISTENT UPPER LEVEL NORTHWEST FLOW
PATTERN. THE GFS IS SHOWING MORE QPF THAN PREVIOUS RUNS WITH THE
ARCTIC FRONT COMING THROUGH LATE SUNDAY. 850 MB TEMPS AND DEEP LAYER
THICKNESSES INDICATE IT WOULD BE ALL SNOW.

.PAH...WINTER WEATHER ADVISORY THRU THIS EVENING AREA WIDE.
