Ice Storm in Missouri, January 5, 2005

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
400 AM CST WED JAN 5 2005

.DISCUSSION...

MAIN CONCERN IS PRECIP TYPE AND AMOUNTS. SO FAR THE ONLY LOCATIONS
WHICH HAVE SLEET/SNOW ARE IN EXTREME NORTHWEST MISSOURI AND EXTREME
NORTHEAST KANSAS. AN INCH OR TWO OF ACCUMULATION HAS BEEN REPORTED
SO FAR. WHERE FREEZING RAIN CONTINUES...GENERALLY AROUND ONE HALF
INCH OF ICE HAS ACCUMULATED FROM THE NEARLY ONE INCH OF RAINFALL.
THE RAIN CONTINUES ACROSS OUR FAR SOUTH/SOUTHEAST COUNTIES AS
WELL...WHERE AROUND AN INCH OF RAIN HAS ALSO FALLEN.

RADAR AND SURFACE OBS SHOW A LARGE AREA OF PRECIPITATION MOVING
NORTHEAST OUT OF OKLAHOMA ACROSS KANSAS AND INTO MISSOURI. THE LINE
BETWEEN THE FREEZING RAIN MIXED WITH SLEET AND THE SNOW/SLEET MIXED
WITH FREEZING RAIN CURRENTLY STRETCHES FROM NEAR MOUND CITY MISSOURI
TO MARYVILLE AND GRANT CITY. THIS LINE SHOULD CONTINUE TO MOVE
SLOWLY EAST AND A LITTLE SOUTH TODAY AS CANADIAN HIGH PRESSURE OOZES
DOWN THE PLAINS. THE LONGER IT TAKES TO MOVE EAST...THE LESS SNOW
WILL FALL...AND HAVE BACKED OFF ON SNOW AMOUNTS FOR MOST AREAS.
EXPECT THE LINE TO BE EAST OF THE KANSAS CITY METRO AREA BY NOON AND
BE EAST OF THE FORECAST AREA BY 6PM.

THERE MAY BE A BIT OF A BREAK IN THE PRECIPITATION ACROSS NORTHWEST
MISSOURI THIS MORNING.  HOWEVER THINK THAT AREA WILL SEE A ROUND OF
MODERATE SNOW THIS AFTERNOON INTO THE EVENING AS THE UPPER LEVEL
SYSTEM MOVES ACROSS. TOTAL SNOWFALL SHOULD RANGE FROM 4 TO 6 INCHES
IN THE NORTHWEST CORNER OF MISSOURI AND ALONG THE IOWA BORDER. SNOW
AMOUNTS WILL DROP OFF TO THE SOUTHEAST WITH LITTLE MORE THAN AN INCH
OF SNOW EXPECTED FROM THE SOUTHERN PORTION OF THE KANSAS CITY METRO
EAST TO MOBERLY.

.PREV DISCUSSION...

1100 PM TUE...
CONVECTION FIRING AS EXPECTED FROM NORTHERN OKLAHOMA SWWD INTO
WESTERN TEXAS. PRECIPITATION FURTHER NORTH...IN STOUT ISENTROPIC
LIFT REGIME...HAS BEEN MORE SCATTERED IN NATURE BUT A BAND OF
STEADIER PRECIPITATION IS LIFTING NORTHEAST TOWARDS THE KC METRO
AREA.

00Z ETA/GFS RUNS ALL SHIFTING QPF FIELDS FURTHER SOUTH...WITH THE
GFS THE FURTHEST NORTH. OVERALL PREFER ITS SOLUTION GIVEN EVOLVING
THERMAL FIELDS THIS EVENING...AND A SIMPLE DISTANCE/SPEED OFF THE
ONGOING CONVECTION IN OKLAHOMA. SO FAR A WIDESPREAD QUARTER TO HALF
INCH OF ICE HAS BEEN REPORTED NORTHWEST OF A LINE FROM KANSAS CITY
TO TRENTON TO UNIONVILLE. UPWARDS OF AN INCH OF SLEET ALSO HAS BEEN
REPORTED AROUND MARYVILLE.

CURRENT THINKING IS THAT FAR NORTHWEST MISSOURI MAY NOT SEE AS MUCH
SNOW AS ORIGINALLY EXPECTED...BUT COMBINATION OF ICE...SLEET AND
SNOW STILL WORTHY OF A WARNING THROUGH TOMORROW MORNING. BIGGEST
BRUNT OF ICING LATE TONIGHT INTO WEDNESDAY MAY RUN FROM THE SOUTH
SIDE OF KC METRO TO MOBERLY...WITH SLEET BECOMING MORE COMMON ACROSS
THE NORTHLAND EARLY WEDNESDAY. UPDATED FORECASTS REFLECT THESE
CHANGES. CHANGED HEADLINES EARLIER TO A WINTER STORM WARNING FOR
AREAS ALONG AND NORTH OF US HIGHWAY 36...TO BETTER REFLECT STORM
CHARACTERISTICS...AND THIS STILL LOOKS REASONABLE.

FURTHER SOUTH...CONCERNS REVOLVE AROUND HYDRO ISSUES. PORTIONS OF
CENTRAL MISSOURI HAVE ALREADY EXPERIENCED FLASH FLOODING...AND MODEL
FORECASTS ARE QUITE AGGRESSIVE IN QPF IN THESE AREAS. SO LONG AS
TEMPERATURES CONTINUE TO HOLD ABOVE FREEZING FROM BUTLER TO
BOONVILLE...FLASH FLOODING WILL REMAIN A DISTINCT THREAT.
