AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE ST LOUIS MO
830 PM CST SAT JAN 29 2011

.UPDATE...
/830 PM CST SAT JAN 29 2011/

THE 18Z RUNS AND FIRST GLANCE AT THE INCOMING 00Z NAM CONTINUE TO
ADVERTISE A VERY POWERFUL WINTER STORM IMPACTING THE REGION EARLY
THIS COMING WEEK. FREEZING DRIZZLE AND FREEZING RAIN WILL BEGIN AS
EARLY AS LATE SUNDAY NIGHT/EARLY MONDAY MORNING AND CONTINUE IN
WAVES THROUGH MONDAY EVENING. ICE ACCUMULATION DURING THIS PERIOD
WILL LIKELY STAY BELOW WARNING CRITERIA...UNDER A QUARTER OF AN
INCH.

PRECIPITATION INTENSITY WILL BE ON THE INCREASE MONDAY NIGHT THROUGH
TUESDAY NIGHT WITH SIGNIFICANT ICE AND SNOW/SLEET ACCUMULATION
FORECAST BY NEARLY ALL THE MODEL GUIDANCE. EXACT AMOUNTS/PLACEMENT
ARE STILL UP FOR DEBATE AND WILL DEPEND HIGHLY ON WHERE THE
TRANSITION FROM FREEZING RAIN...TO SLEET AND THEN TO SNOW LAYS OUT
ACROSS THE CWA.

SLU ANALOGS COMPARE THIS UPCOMING WINTER STORM TO THE 1982 SNOW
STORM THAT MANY REMEMBER IN ST. LOUIS AS THE BLIZZARD OF 82...AND
THE JANUARY 30 2006 ICE AND SNOW EVENT THAT LEFT NEARLY 500000
PEOPLE WITHOUT POWER FOR DAYS ACROSS EASTERN MISSOURI AND ILLINOIS.

THIS WINTER STORM HAS THE POTENTIAL TO PRODUCE CRIPPLING AMOUNTS OF
SLEET AND SNOW...IN EXCESS OF 12 INCHES...AND ICE ACCUMULATIONS IN
EXCESS OF 1/2 INCH. ICE ACCUMULATION OF THIS MAGNITUDE WOULD LEAD
TO POWER OUTAGES FROM DOWNED TREES AND POWER LINES.

IN ADDITION...STRONG WINDS ARE FORECAST TO DEVELOP IN THE WAKE OF
THIS STORM TUESDAY NIGHT AND WEDNESDAY WHICH COULD LEAD TO BLOWING
AND DRIFTING SNOW AND ADDITIONAL POWER OUTAGES WHERE SIGNIFICANT ICE
ACCUMULATION OCCURS.

CONFIDENCE IS HIGH ENOUGH TO ISSUE A WINTER STORM WATCH FOR THE AREA
FROM MONDAY THROUGH WEDNESDAY MORNING. FEEL THERE IS NO NEED TO
TREAT THIS AS TWO SEPERATE EVENTS...AS THERE WILL LIKELY BE LITTLE
IF ANY BREAK BETWEEN THE LIGHT FREEZING DRIZZLE/FREEZING RAIN ON
MONDAY AND MONDAY NIGHT AND THE SIGNIFICANT SNOW/ICE ACCUMULATION
THAT OCCURS TUESDAY AND TUESDAY NIGHT.

CVKING

&&

.DISCUSSION...
/358 PM CST SAT JAN 29 2011/

RATHER QUIET WEATHER DAY FOR FORECAST AREA...WITH A MIX OF SUN AND
CLOUDS ACROSS FORECAST AREA. THIS HAS ALLOWED TEMPS TO WARM UP INTO
THE MID 30S TO LOW 50S ACROSS THE REGION. AS FOR THE FORECAST...
MAIN ISSUE CONTINUES TO BE STORM SYSTEM THAT IS EXPECTED TO BEGIN
AFFECTING THE AREA LATE SUNDAY NIGHT AND PERSIST THROUGH EARLY
WEDNESDAY.

FOR TONIGHT...WAA CLOUDS TO BE ON THE INCREASE ACROSS REGION AS
FRONTAL BOUNDARY REMAINS STALLED JUST TO OUR SOUTH. SOME MODELS
INDICATING SOME LIGHT PCPN IS POSSIBLE DUE TO THE WAA...BUT
CONFIDENCE IS NOT HIGH WITH IT...SO WILL KEEP FORECAST DRY FOR NOW.
AS FOR LOW TEMPS...THEY WILL RANGE FROM THE LOW 20S FAR NORTH TO THE
LOW 30S FAR SOUTH.

ON SUNDAY...MID LEVEL WAA TO REMAIN IN PLACE OVER AREA...SO EXPECT A
CLOUDY DAY ACROSS THE REGION WITH HIGH TEMPS IN THE LOW 30S TO MID
40S. WITH ALL OF THIS WAA...LOW LEVEL MOISTURE WILL BE ON THE
INCREASE AHEAD OF A DECENT SHORTWAVE THAT IS CURRENTLY LIFTING OUT
OF THE GULF OF CALIFORNIA. THE MID LEVELS WILL REMAIN DRY SO PCPN
THAT DOES DEVELOP SUNDAY NIGHT INTO MONDAY NIGHT WILL BE VERY LIGHT
IN NATURE...MAINLY DRIZZLE OR FREEZING DRIZZLE...THOUGH SOME LIGHT
FREEZING RAIN NOT OUT OF THE QUESTION EITHER. IT WILL START OVER
WESTERN PORTIONS OF FORECAST AREA AND SPREAD ACROSS THE ENTIRE
FORECAST AREA DURING THE DAY ON MONDAY AND PERSIST INTO MONDAY
NIGHT. DEPENDING ON HOW WARM TEMPERATURES ARE ALOFT....COULD SEE A
SNOW/SLEET MIX IN NORTHERN PORTIONS OF FORECAST AREA. AS FOR SNOW
AND ICE ACCUMULATIONS...THEY WILL BE ON THE LIGHT SIDE...LESS THAN
AN INCH OF SNOW AND ONLY A LIGHT GLAZING OF ICE. AS FOR LOW TEMPS ON
SUNDAY NIGHT...THEY WILL BE IN THE LOW 20S TO LOW 30S...AND HIGHS ON
MONDAY IN THE UPPER 20S TO AROUND 40.

LATE MONDAY NIGHT INTO EARLY TUESDAY WILL BE THE TRANSITION TIME
FROM THE FIRST SHORTWAVE TO THE MORE SIGNIFICANT SHORTWAVE THAT WILL
APPROACH AREA FROM NEW MEXICO. AHEAD OF SYSTEM...MOISTURE WILL BE ON
THE INCREASE WITH THE ENTIRE COLUMN MOISTENING UP...WITH PCPN ON THE
INCREASE IN COVERAGE AND INTENSITY. STILL SOME UNCERTAINTIES WITH
THE EXACT STRENGTH AND TRACK OF THE SYSTEM...SO THESE DIFFERENCES
WILL ULTIMATELY DETERMINE WHETHER THE PRECIPITATION WILL FALL AS
FREEZING RAIN...SLEET OR SNOW AND HOW MUCH OF EACH. BY TUESDAY
MORNING...CENTRAL AND NORTHEAST MISSOURI AS WELL AS WEST CENTRAL
ILLINOIS WILL LIKELY SEE ALL SNOW...WHILE LOCATIONS TO THE SOUTH AND
EAST WILL SEE A MIX OF SNOW...SLEET AND FREEZING RAIN...CHANGING
OVER TO ALL SNOW BY EARLY TUESDAY EVENING. THE HEAVIEST PCPN APPEARS
LIKELY TO OCCUR ON TUESDAY AND TUESDAY NIGHT...RESULTING IN A RAPID
ACCUMULATION OF HEAVY SNOW AND ICE...INITIALLY THE HEAVY SNOW WILL BE
ALONG AND NORTH OF I-44 DURING THE DAY ON TUESDAY...WITH LIGHT TO
MODERATE ICE ACCUMULATIONS POSSIBLE SOUTH OF THIS AREA...THEN SEE A
SECONDARY MAXIMUM OF HEAVY SNOW A BIT FURTHER TO THE NORTH TUESDAY
NIGHT AS SYSTEM BEGINS TO LIFT OUT OF THE AREA. ANOTHER ISSUE WILL
BE WINDS...AS DEEPENING AREA OF LOW PRESSURE TRACKS JUST TO OUR
EAST...WINDS TO BEGIN PICKING UP FROM THE NORTHEAST TO NORTH WITH
GUSTS TO AROUND 35 KTS AT TIMES...WHICH COULD MAKE FOR TREACHEROUS
CONDITIONS DUE TO THE SNOWFALL.

SNOW TO TAPER OFF TO FLURRIES BY WEDNESDAY...WITH STRONG RIDGE OF
HIGH PRESSURE BUILDING IN. EXPECT TEMPS TO DROP OFF WITH INTO THE
TEENS TO UPPER 20S ON WED AND THU...WITH LOWS IN THE SINGLE DIGITS
BOTH WED NIGHT AND THU NIGHT. BEYOND THAT...TEMPS TO MODERATE
BIT...BUT REMAIN BELOW NORMAL THROUGH THE REST OF THE FORECAST
PERIOD.

.AVIATION...
/528 PM CST SAT JAN 29 2011/

MID CLOUDS ASSOCIATED WITH A DISTURBANCE TO THE NORTH WILL SPREAD
ACROSS THE TAF SITES TONIGHT. AN AREA OF MVFR CIGS WAS ALSO SLIDING
SWD BUT THESE CLOUDS WERE LARGELY OBSCURED ON SATELLITE IMAGERY BY
THE HIGHER CLOUDS. FEW CHANGES MADE TO THE TIMING OF MVFR CIGS AS
TRENDS IN THE PREVIOUS SET OF TAFS STILL LOOK GOOD. AFTER SEVERAL
HOURS OF VFR CONDITIONS DURING THE DAY...MODEL GUIDANCE SUGGESTS
THAT MVFR CIGS WILL RETURN ON SUNDAY NIGHT. LGT/VAR WINDS WILL
TURN NELY TO ELY AS AN AREA OF HIGH PRESSURE BUILDS INTO THE
MIDWEST.

SPECIFICS FOR KSTL...MID CLOUDS WILL SPREAD ACROSS THE AREA
TONIGHT WITH LOWER CIGS EXPECTED TO ARRIVE AROUND 08Z. THESE MVFR
CLOUDS WERE BEING OBSCURED ON SATELLITE IMAGERY BY THE HIGHER MID
LEVEL DECK SO SOME ADJUSTMENTS TO THE TIMING MAY BE NEEDED TONIGHT.
LGT/VAR WINDS WILL TURN NELY TO ELY AS AN AREA OF HIGH PRESSURE
BUILDS INTO THE MIDWEST.

...SIGNIFICANT ACCUMULATIONS OF ICE AND SNOW POSSIBLE MONDAY
THROUGH WEDNESDAY...

THE LATEST RUNS OF THE COMPUTER MODELS CONTINUE TO SHOW THAT A
MAJOR WINTER STORM WILL LIKELY BRING AN EXTENDED PERIOD OF
ACCUMULATING ICE AND SNOW TO THE REGION EARLY NEXT WEEK. THERE
CONTINUES TO BE DIFFERENCES BETWEEN THE COMPUTER MODELS ON THE
EXACT STRENGTH AND TRACK OF THIS STORM SYSTEM. THESE DIFFERENCES
WILL ULTIMATELY DETERMINE WHETHER THE PRECIPITATION WILL FALL AS
FREEZING RAIN...SLEET OR SNOW AND HOW MUCH OF EACH.

AT THIS TIME...LIGHT FREEZING DRIZZLE IS EXPECTED TO DEVELOP OVER
CENTRAL AND NORTHEAST MISSOURI ON SUNDAY NIGHT WELL AHEAD OF THE
SYSTEM WITH A MIX OF WINTRY PRECIPITATION SPREADING ACROSS MUCH
OF THE AREA MONDAY AND MONDAY NIGHT. SOME LIGHT SNOW ACCUMULATION
IS EXPECTED ALONG AND NORTH OF INTERSTATE 70 ALONG WITH SOME LIGHT
ICE ACCUMULATION ALONG AND SNOW OF INTERSTATE 70.

THE PRECIPITATION WILL BECOME STEADY AND HEAVY AT TIMES DURING
THE DAY TUESDAY. NORTHEAST MISSOURI AND WEST CENTRAL ILLINOIS WILL
LIKELY SEE ALL SNOW...WHILE LOCATIONS IN SOUTHEAST MISSOURI AND
SOUTHERN ILLINOIS WILL TEND TO SEE A MIX OF SLEET AND FREEZING
RAIN. THE HEAVIEST PRECIPITATION APPEARS LIKELY TO OCCUR ON
TUESDAY AND TUESDAY NIGHT AND WILL RESULT IN A RAPID ACCUMULATION
OF HEAVY SNOW AND ICE. PRECIPITATION WILL GRADUALLY CHANGEOVER TO
ALL SNOW TUESDAY NIGHT AND TAPER TO FLURRIES ON WEDNESDAY.

NORTHERLY WINDS WILL INCREASE TUESDAY INTO WEDNESDAY WHICH MAY
CAUSE SOME BLOWING AND DRIFTING SNOW. IN ADDITION...BITTERLY COLD
AIR WILL MOVE INTO THE REGION WITH LOW TEMPERATURES DIPPING INTO
THE SINGLE DIGITS BOTH WEDNESDAY AND THURSDAY NIGHT WITH BELOW
ZERO WIND CHILLS.

THERE CONTINUES TO BE SOME UNCERTAINTY WITH HOW MUCH AND WHAT TYPE
OF PRECIPITATION WILL FALL AT ANY GIVEN LOCATION. HOWEVER IT DOES
LOOK LIKELY THAT A MAJOR WINTER STORM WILL IMPACT THE AREA EARLY
NEXT WEEK. WINTER STORM WATCHES AND WARNING WILL LIKELY BE ISSUED
FOR THIS STORM LATER TONIGHT OR ON SUNDAY. STAY TUNED TO NOAA
WEATHER RADIO OR YOUR LOCAL MEDIA FOR THE LATEST FORECAST.
