AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
341 AM CDT FRI APR 15 2011

.DISCUSSION...

AN IMPRESSIVE DEEPENING UPPER LEVEL LOW CONTINUES TO SPIN ACROSS
WESTERN KANSAS EARLY THIS MORNING.  EARLIER TONIGHT...INITIAL BAND
OF CONVECTION LIFTED NORTHEAST THROUGH THE CWA WITH RAINFALL TOTALS
APPROACHING AN INCH OR MORE IN SOME LOCATIONS.  WEAK CONVECTIVE
INDUCED VORT MAX CONTINUES TO LIFT NE ACROSS WEST CENTRAL MO...AND
IS EXPECTED TO CONCENTRATE A MORE FOCUSED AREA OF RA/TSRA INTO
CENTRAL MO THROUGH DAYBREAK.  OTHER CONCERN OVERNIGHT HAS BEEN
WINDS...WITH A COMBINATION OF INCREASING PRESSURE GRADIENT FORCE
FROM DEVELOPING SFC LOW TO THE WEST AND DOWNWARD MOMENTUM TRANSFER
ON WESTERN FLANK OF STRATIFORM PRECIP SHIELD PRODUCING OCCASIONAL
GUSTS HIGHER THAN 40-50 MPH.

THROUGH DAYBREAK...HRRR AND OTHER MESOSCALE MODELS INDICATE THE
CONTINUED DEEPENING OF UPPER LEVEL LOW AND SURFACE LOW PRESSURE JUST
WEST OF THE AREA.  AS UPPER LOW BEGINS TO MOVE SLOWLY EASTWARD AND
SURFACE LOW DEEPENS JUST WEST OF KC...OCCLUDED FRONT IS EXPECTED TO
PIVOT NORTHEASTWARD INTO THE CWA. INITIAL BAND OF RAIN IN WEST
CENTRAL MO WILL BEGIN TO ROTATE BACK NORTHWEST INTO NORTHERN
MO...WITH SCATTERED THUNDERSTORM ACTIVITY TO CONTINUE ON THE
NORTHERN SIDE OF THE OCCLUDED FRONT AS LLJ INTENSIFIES. MODELS SEEM
TO BE RUNNING A BIT BEHIND WITH PRECIP...WITH FRONT ARRIVING FASTER
THAN INDICATED. 06Z NAM AND RUC SEEM TO HAVE THE BEST HANDLE OF
ONGOING ACTIVITY. WINDS ARE EXPECTED TO REMAIN RATHER GUSTY IN NORTHERN MO
THROUGH DAYBREAK.

FOR THE DAYTIME HOURS...THE MOST WIDESPREAD PRECIPITATION WILL REMAIN IN
THE NORTHERN HALF OF THE CWA AS DRY SLOT WILL ROTATE THROUGH SOUTHERN
MO THIS MORNING. TEMPERATURES ARE NOT EXPECTED TO CLIMB UPWARDS MUCH
TODAY WITH AREAS NORTH OF THE OCCLUDED FRONT EXPERIENCING MORNING
HIGHS. BY 18Z SFC LOW PRESSURE SHOULD BE CENTERED BETWEEN KC AND
STJ...WITH INCREASING LOW LEVEL COLD AIR ADVECTION BEGINNING TO ROTATE
AROUND THE BACKSIDE OF THE UPPER LOW. COLDER SURFACE TEMPERATURES
WILL ACTUALLY BEGIN TO ADVECT IN FROM THE SOUTHWEST WITH STEADY TO
FALLING TEMPERATURES IN THE WESTERN ZONES IN THE AFTERNOON.
WIDESPREAD PRECIPITATION EXPECTED IN NORTHERN MO...KANSAS AND
NEBRASKA THROUGH THE AFTERNOON AS TROWAL REMAINS OVERHEAD...WITH
PRECIP AMOUNTS APPROACHING A HALF INCH IN SOME SPOTS. LATEST GUIDANCE
SUGGESTS THAT SFC LOW MAY TRACK SLIGHTLY FURTHER NORTHWEST...WITH
OCCLUDED FRONT MOVING NORTHWARD FASTER THAN EARLIER MODELS SUGGESTED.
THUS...WILL USE 3 HR WEATHER GROUPS AND ADVANCE PRECIP A BIT FURTHER
NORTH AND LOWER POPS IN THE SOUTHERN HALF OF THE CWA FOR THE MAJORITY
OF THE DAY. OTHER MESOSCALE MODELS SUGGEST MORE SCATTERED SHOWER
REDEVELOPMENT OVER THE REMAINDER OF THE CWA LATER IN THE AFTN AND THE
POTENTIAL OF LOW TOP SUPERCELL ACTIVITY EAST OF THE CWA WHERE
SCATTERING OF CLOUDS IN THE DRY SLOT REMAINS SLIGHTLY HIGHER.

TONIGHT...THE UPPER LEVEL LOW WILL QUICKLY BEGIN TO LIFT NORTHEAST
THIS EVENING AS PROGRESSIVE NORTHERN STREAM TROUGH BEGINS TO MOVE
OUT OF THE NORTHERN ROCKIES.  HOWEVER...LINGERING WAA ON THE WESTERN
FLANK OF THE UPR LOW SHOULD ALLOW FOR LIGHT SHRA ACTIVITY TO
PERSIST INTO THE EARLY EVENING.  STRONG ISENTROPIC DOWNGLIDE SHOULD
BRING PRECIP TO AN END FROM WEST TO EAST AFTER MIDNIGHT.
TEMPERATURES WILL FALL INTO THE 30S...WITH GUSTY WEST TO NORTHWEST
WINDS BETWEEN 15 AND 25 MPH LEADING TO RATHER RAW CONDITIONS THROUGH
SATURDAY MORNING.

SATURDAY AND SUNDAY...PLEASANT CONDITIONS EXPECTED THIS WEEKEND ON
THE BACKSIDE OF THE DEPARTING UPR TROUGH.  QUASI-ZONAL FLOW WILL
ALLOW FOR A QUICK WARMUP NEAR 60 ON SATURDAY UNDER A SUNNY SKY.
SUNDAY WILL FEATURE EVEN BETTER CONDITIONS DESPITE A WEAK SURFACE
TROUGH APPROACHING FROM THE NORTHWEST.  WILL NEED TO KEEP AN EYE ON
A WEAK SHORTWAVE MOVING THROUGH THE REGION ON SUNDAY.  THIS WAVE IS
POORLY SAMPLED AND THUS POORLY HANDLED BY CURRENT GUIDANCE...BUT
SEVERAL MODELS INDICATE A DEVELOPING WARM FRONT UNDERNEATH
INCREASING WAA ALOFT.  MOISTURE WILL REMAIN LIMITED...AND AN
INCREASE IN MID-LVL CLOUDS IS ALL THAT IS ANTICIPATED ATTM.

31

MEDIUM RANGE (MONDAY THROUGH FRIDAY)...

FLOW ACROSS THE CONUS THROUGH THE MEDIUM RANGE PERIOD WILL REMAIN
QUASI-ZONAL...WITH A TREND TOWARDS WEAK TROUGHING IN THE WEST AND
SEVERAL LOW AMPLITUDE PERTURBATIONS EJECTING EAST INTO THE PLAINS.
MODELS CONTINUE TO CONVERGENCE ON BETTER IDENTIFICATION AND TIMING
OF THE FIRST SET OF WAVES ACTING UPON ENHANCED BAROCLINICITY WITHIN
THE LOCAL REGION...HOWEVER STILL REMAIN AT ODDS LATER IN THE PERIOD
DUE TO FAR UPSTREAM INFLUENCES. MOST NOTABLE SHORTWAVE WILL
PROPAGATE EAST FROM THE GREAT BASIN...AND INTENSIFY OVER THE UPPER
MIDWEST DURING THE TUESDAY/WEDNESDAY TIME FRAME...PULLING A SFC
FRONT THROUGH THE CWA WITH INCREASING UPPER LEVEL DYNAMIC SUPPORT.
LARGER QUESTION TOWARDS THE END OF THE WEEK IS WHETHER THIS BOUNDARY
WILL SLIDE FAR ENOUGH SOUTH TO PRECLUDE FURTHER PRECIPITATION
CHANCES. SPREAD AMONG ALL OPERATIONAL AND ENSEMBLE MEMBERS REMAINS
HIGH ENOUGH TO KEEP SOME POP MENTION THROUGH MOST OF THE MEDIUM
RANGE...THOUGH WOULD NOT EXPECT PERSISTENT PRECIPITATION...BUT
RATHER JUST A TYPICAL UNSETTLED SPRING PATTERN.

THERE IS ENOUGH EVIDENCE PRESENTED BY RECENT MODEL OUTPUT TO SUGGEST
MOST...IF NOT ALL THE OF FORECAST AREA WILL BE SOLIDLY IN THE WARM
SECTOR OF THE DEVELOPING CYCLONE MONDAY AND TUESDAY. HAVE INCREASED
TEMPERATURE FORECASTS...WITH MORE WEIGHT TOWARDS THE WARMER ECMWF
(WHICH HAS PERFORMED BETTER IN ANOMALOUSLY WARM REGIMES LATELY).
BASED ON LOW LEVEL THICKNESS PROGS...MAY STILL BE TOO CONSERVATIVE
TUESDAY...WITH HIGH CONCEIVABLY BREACHING A 15F ANOMALY.
OTHERWISE...HAVE KEPT TEMPERATURES NOT FAR FROM CLIMATOLOGY AND
WITHIN A CONSENSUS AVERAGE POST FRONTAL DURING THE END OF THE WEEK.

21

&&

.AVIATION...

FOR THE 06Z TAFS...PRIMARY BAND OF NON-STOP SHOWERS HAS SHIFTED EAST
OF THE TERMINALS. HOWEVER...NEW SHOWERS HAVE FORMED OVER SW MO AND
RADAR SHOWS THEM SPREADING NNE. LATEST SHORT RANGE MODELS SUGGEST
THE TERMINALS WILL BE NEAR THE WEST EDGE OF THE SHOWERS AS THEY
ROTATE TO THE NORTH. UPSTREAM OBSERVATIONS SHOW MVFR CLOUDS FORMING
ACROSS EASTERN KS AND EXPECT THESE CLOUDS TO SPREAD INTO THE
TERMINALS OVERNIGHT.

VERTICALLY STACKED STORM SYSTEM WILL SLIDE ESE AND SURFACE LOW
POSITION WILL PASS VERY CLOSE TO KMCI/KMKC. WEATHER WILL DEPEND
CONSIDERABLY AS TO WHERE THE LOW WILL TRACK. KMKC STANDS A BETTER
CHANCE OF SEEING WINDS SWITCH TO THE SOUTH WITH CEILINGS REMAINING
MVFR VS KMCI WHICH COULD SEE CEILINGS DROP TO IFR FRIDAY MORNING AND
STAY THAT WAY UNTIL THE WINDS SWITCH TO THE NW IN THE AFTERNOON.
KSTJ WILL LIKELY SEE IFR CEILINGS FOR FRIDAY MORNING.

HARD TO JUSTIFY GOING WITH PREVAILING RAIN BETWEEN NOW AND 18Z
THURSDAY AS RAIN WILL MOST LIKELY BE TIED TO VORTICITY SPOKES
ROTATING AROUND THE CLOSED UPPER LOW. BETTER BET OF SEEING MORE
WIDESPREAD LIGHT RAIN ON THE BACKSIDE OF THE SYSTEM FRIDAY AFTERNOON
AND EVENING.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST...NORTH CENTRAL AND
WEST CENTRAL MISSOURI...AS WELL AS EXTREME EASTERN KANSAS.

.DAY ONE...TONIGHT

A LINE OF STRONG TO SEVERE THUNDERSTORMS OVER FAR EASTERN KANSAS WILL
SHIFT EAST INTO EXTREME WESTERN MISSOURI EARLY THIS EVENING.
INDIVIDUAL STORMS WILL PEEL AWAY FROM THE LINE AND TRACK TO THE
NORTH. THE AIRMASS AHEAD OF THIS LINE OF THUNDERSTORMS IS MUCH MORE
STABLE SO THE EXPECTATION IS THE SEVERITY OF THE THUNDERSTORMS WILL
DECREASE AS THEY CROSS THE MISSOURI AND KANSAS STATE LINE. WHILE THE
PRIMARY SEVERE THREAT WILL REMAIN SOUTHWEST OF THE OUTLOOK
AREA...THERE IS STILL A CHANCE THAT A FEW SEVERE THUNDERSTORMS COULD
AFFECT PARTS OF EXTREME EAST CENTRAL KANSAS AND FAR WESTERN
MISSOURI...GENERALLY WEST OF AN ATCHISON KANSAS TO CLINTON
LINE...WHICH INCLUDES THE GREATER KANSAS CITY AREA. ALTHOUGH THE
PRIMARY SEVERE THREATS WILL BE FROM LARGE HAIL AND DAMAGING
WINDS...AN ISOLATED TORNADO IS POSSIBLE MAINLY SOUTHWEST OF A LINE
FROM PAOLA TO BUTLER. THE THREAT FOR SEVERE WEATHER SHOULD END BY
LATE THIS EVENING. IN ADDITION...LOCALLY HEAVY RAINFALL IS LIKELY
TONIGHT ACROSS THE ENTIRE OUTLOOK AREA WHICH MAY CAUSE LOCALIZED
FLOODING.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

SCATTERED THUNDERSTORMS WILL BE POSSIBLE OVER THE ENTIRE REGION FROM
MONDAY NIGHT THROUGH TUESDAY NIGHT.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS EVENING OVER PARTS OF EAST
CENTRAL KANSAS AND WEST CENTRAL MISSOURI...GENERALLY ALONG AND WEST
OF A KANSAS CITY TO CLINTON LINE.
