AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE ST LOUIS MO
410 PM CDT SUN MAR 10 2013

.SHORT TERM...(TONIGHT)
ISSUED AT 359 PM CDT SUN MAR 10 2013

SURFACE LOW CURRENTLY OVER CENTRAL MO WILL CONTINUE TO LIFT
NORTHEASTWARD THIS EVENING. DRY SLOT ASSOCIATED WITH THE
SYSTEM...IS MAKING PROGRESS TO THE EAST ACROSS FORECAST AREA LATE
THIS AFTERNOON...SO PCPN TO COME TO AN END MOST LOCATIONS BY 00Z
MONDAY. HOWEVER...HAVE A LINE OF SHOWERS ASSOCIATED WITH MAIN COLD
FRONT SLIDING EAST INTO COLUMBIA AREA BETWEEN 5 AND 6 PM AND
PROGRESS TO THE EAST THROUGH THE EARLY EVENING HOURS.

THEN HAVE TO DEAL WITH WRAP AROUND/DEF ZONE PCPN ON BACKSIDE OF
SYSTEM OVERNIGHT...AS COLDER AIR FILTERS IN. WILL SEE LIGHT RAIN
BEGIN TO MIX WITH/CHANGE OVER TO LIGHT SNOW LATE THIS EVENING.  BEST
DYNAMICS ARE NORTH OF FORECAST AREA OVER IOWA...SO ONLY EXPECT A FEW
TENTHS SNOWFALL ACCUMULATION OVER FAR NORTHERN PORTIONS OF FORECAST
AREA OVERNIGHT. AS FOR LOW TEMPS...UPPER 20S TO UPPER 30S CAN BE
EXPECTED.

ON THE FLOOD WATCH FRONT...HEAVIEST RAIN WITH THIS SYSTEM HAS
ENDED OVER THE WATCH AREA. DDITIONAL VERY BRIEF SHOT OF RAIN WILL
FALL WITH THE PASSAGE OF THE AFOREMENTIONED COLD FRONT OVER THE
NEXT COUPLE OF HOURS BUT ADDITIONAL RAINFALL WITH THIS WILL BE

.LONG TERM...(MONDAY THROUGH NEXT SUNDAY)
ISSUED AT 359 PM CDT SUN MAR 10 2013

(MONDAY-WEDNESDAY)

SIMILAR TO MODEL RUNS OF THE PAST 24 HOURS...GUIDANCE BASED OFF OF
THIS MORNINGS 12Z DATA IS STILL FORECASTING UPPER LOW TO DRIFT INTO
WISCONSIN ON MONDAY MORNING. TROF ROTATING AROUND THE LOW WILL SWEEP
INTO THE MID MISSISSIPPI VALLEY DURING THE MORNING..CONTINUING A
CHANCE OF LIGHT SNOW WITH VERY MINOR ACCUMULATIONS OVER N SECTIONS
OF THE CWA.

WHILE THIS THREAT OF SNOW SHOULD WIND DOWN BY MIDDAY...IT APPEARS
CLEARING OF THE CLOUDS WILL BE SLOWER DUE TO EXTENSIVE LOW LEVEL
MOISTURE THAT WILL BE WRAPPING AROUND SYSTEM.  LATEST FORECAST
SOUNDINGS TO SUGGEST SOME CLEARING WORKING INTO MID MISSOURI THIS
AFTERNOON...BUT ELSEHWERE IT APPEARS THAT CLEARING WILL BE DELAYED
UNTIL THE OVERNIGHT HOURS.

THE REMAINDER OF THE SHORT RANGE WILL BE DOMINATED BY NW FLOW AS
UPPER TROF DEEPENDS OVER EAST COAST.  SHORTWAVE ZIPPING THROUGH THE
REGION WILL PRODUCE A BIT OF WAA ON TUESDAY MORNING...FOLLOWED BY A
WEAK SECONDARY SURGE OF COOLER AIR HEADING INTO MIDWEEK.  WITH WEAK
DYNAMICS AND LIMITED MOISTURE NOT LOOKING FOR MUCH IF ANY PRECIP
THREAT WITH THIS SYSTEM.  TEMPERATURE-WISE...NET RESULT OF THE
WAA/CAA COUPLET WILL BE THAT MAX AND MINS ON TUESDAY-WEDNESDAY WILL
REMAIN A BIT BELOW NORMAL AND SHOULD BE FAIRLY SIMILAR.  HIGHS WILL
RANGE FROM THE MID 40S OVER OUR CENTRAL ILLINOIS COUNTIES TO THE
LOWER 50S IN SE MO...WITH LOWS IN THE MID 20S TO LOWER 30S.

(THURSDAY-SUNDAY)
MEDIUM RANGE SOLUTIONS ARE ALL SUGGESTING THAT THE AMPLIFIED UA FLOW
AT MIDWEEK WILL TRANSITION TO A ZONAL FLOW REGIME DURING THE
UPCOMING WEEKEND.  INITIALLY...ON THURSDAY AND FRIDAY...EWD
PROGRESSION OF EAST COAST TROF WILL ALLOW RIDGING...AND WARMER
TEMPS...TO SURGE INTO THE AREA.  HIGHS SHOULD CLIMB 5-10 DEGREES
ABOVE AVERAGE FOR MID MARCH DURING THIS TIME...AND WILL RANGE FROM
THE MID 50S OVER NE MO TO MID AND PERHAPS UPPER 60S OVER EASTERN
OZARKS.  NIGHTS SHOULD BE EQUALLY MILD...WITH LOWS RANGING FROM THE
MID 30S TO MID 40S.

WARMING TREND WILL STALL OUT ON SATURDAY AND SUNDAY AS THE
WESTERLIES BECOME ESTABLISHED OVER THE CONUS.  THIS WILL ALLOW
FRONTAL BOUNDARY TO SLIDE SOUTH AND TAKE UP RESIDENCE OVER THE MID
MISSISSIPPI VALLEY...AND EVENTUALLY SAG A BIT SOUTH ON SUNDAY. THERE
IS ALSO GENERAL AGREEMENT THAT SHORTWAVE THAT WILL HELP FLATTEN THE
RIDGE WILL APPROACH THE REGION LATE FRIDAY NIGHT OR SATURDAY...AND
HAVE CARRIED SOME LOW CHANCE POPS OVER THE NE SECTIONS OF OUR CWA
DURING THIS TIME.
