AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE TOPEKA KS
649 PM CDT THU JUN 14 2012

...UPDATE TO AVIATION...

.DISCUSSION...

19Z SFC OBS SHOWED A COLD FRONT FROM NEAR GOODLAND KS NORTHEAST TO
AROUND SIOUX CITY IA. AHEAD OF THE FRONT OVER NORTH CENTRAL
KS...THERE IS A VERY UNSTABLE AIRMASS WITH OBJECTIVE ANALYSIS
SHOWING CAPE VALUES AROUND 4000 J/KG. ALOFT WATER VAPOR IMAGERY
SUGGESTS THERE IS A DISTURBANCE OVER EASTERN CO MOVING EAST
NORTHEAST...AND CONVECTION HAS DEVELOPED ALONG THE BOUNDARY IN
SOUTHEAST CO.

FOR TONIGHT THINK PRECIP IS LIKELY ACROSS NORTH CENTRAL KS AND HAVE
INCREASED POPS TO AROUND 80 PERCENT. THINKING IS THAT STORMS OFF THE
BOUNDARY WILL FORM INTO SOME KIND OF MCS AND MOVE EAST AND SOUTHEAST
INTO THE AREA EARLY THIS AFTERNOON. DEEP LAYER SHEER IS SOMEWHAT
MARGINAL SUGGESTING THAT SUPERCELL STORM ORGANIZATION COULD BE
DIFFICULT TO COME BY. NEVERTHELESS WITH THIS MUCH INSTABILITY...THERE
WILL BE THE POTENTIAL FOR LARGE HAIL AND DAMAGING DOWNBURST WINDS.
THE MAIN UNCERTAINTY IS IN HOW FAR EAST CONVECTION WILL BE ABLE TO
MAKE IT. INSTABILITY SHOULD DIMINISH INTO WESTERN MO DUE TO LOWER
DEWPOINTS. HOWEVER THERE IS NOT A STRONG SIGNAL FOR HIGHER
INHIBITION FURTHER EAST. SO THINK THAT IF A COLD POOL IS ABLE TO
DEVELOP...THAT STORMS SHOULD MOVE INTO NORTHEAST AND EAST CENTRAL KS
OVERNIGHT. ANOTHER CONCERN THAT WILL NEED TO BE MONITORED IS THE
POTENTIAL FOR EXCESSIVE RAINFALL. WITH PRECIPITABLE WATERS INCREASING
TO NEAR 2 INCHES...SOME MODEL QPF SOLUTIONS SHOW RAINFALL AMOUNTS
OVER 2 INCHES IN SOME LOCATIONS. THINGS ARE A LITTLE MORE UNCERTAIN
FOR FRIDAY WITH MODELS SHOWING SOME KIND OF CONVECTIVE MCV OVER
NORTHEAST KS WITH THE POTENTIAL FOR NUMEROUS OUTFLOW BOUNDARIES IN
THE AREA. THEREFORE MAINTAINED THE PREV FORECAST OF 50 PERCENT POPS.
WITH MORE CLOUD COVER EXPECTED AND CHANCES FOR RAIN...HIGHS FRIDAY
SHOULD STAY IN THE 80S DUE TO WEAKER MIXING AND SLIGHTLY COOLER
TEMPS ALOFT.

WOLTERS

LONG TERM...SATURDAY THROUGH THURSDAY...LITTLE OVERALL CHANGE TO
FORECAST PHILOSOPHY DURING THE PERIOD...MINUS A SLIGHTLY MORE
AGGRESSIVE UPPER WAVE TOWARDS THE END OF THE PERIOD. MODEL CONSENSUS
CONTINUES TO DEPICT A PATTERN CHARACTERIZED BY AN ACTIVE NORTHERN
STREAM...WITH ONLY SUBTLE WAVES AND SURFACE FEATURES ACROSS OUR
REGION THROUGH EARLY NEXT WEEK. THIS CONTINUES SOME DEGREE OF
UNCERTAINTY TO THE SPECIFIC TIMING...LOCATION AND PERCENTAGE OF
PRECIPITATION CHANCES DURING THE EXTENDED.

A STRONG SHORTWAVE THROUGH QUICKLY MOVES ACROSS THE NORTHERN CONUS
ON SATURDAY...WITH AN ASSOCIATED COLD FRONT APPROACHING THE KS/NE
BORDER BY SAT AFTERNOON. THE PERIPHERY OF STRONGER FLOW ALOFT AND
LARGE SCALE ASCENT BRIEFLY OVERSPREADS THE CWA...AND CONVECTION IS
EXPECTED TO DEVELOP ALONG THE PRIMARY BOUNDARY AND/OR REMNANT
OUTFLOW BOUNDARIES...ESPECIALLY DURING PEAK HEATING. CHANCES FOR
THUNDERSTORMS WILL OVERSPREAD MUCH OF THE CWA DURING THE
EVENING/OVERNIGHT HOURS...WITH A GRADUAL WEAKENING TREND AS THE
ACTIVITY MOVES SOUTH WITH THE DEPARTING UPPER SUPPORT AND INCREASING
STABILITY. THE EFFECTIVE FRONTAL BOUNDARY...LIKELY PARTIALLY
REINFORCED FROM CONVECTION...WILL BECOME QUASISTATIONARY ON SUNDAY
AND MAY BEGIN TO DRIFT NORTH. A FEW THUNDERSTORMS WILL BE POSSIBLE
ACROSS THE EASTERN HALF ON SUNDAY...BUT SHOULD BE LIMITED IN
COVERAGE WITH THE LACK OF UPPER SUPPORT AND AN INCREASING EML.

MUCH OF THE AREA WILL REMAIN DRY MONDAY THROUGH WEDNESDAY AS WEAK
UPPER RIDGING BUILDS INTO THE PLAINS...NOTABLE WAVES REMAIN WELL
DISPLACED TO THE NORTH...AND A STRONG EML BUILDS INTO THE AREA. THE
PATTERN APPEARS TO CHANGE WEDNESDAY NIGHT INTO THURSDAY AS A MORE
AMPLIFIED PATTERN COMMENCES ACROSS THE NORTHERN/CENTRAL PLAINS AND A
COLD FRONT MOVES TOWARDS/THROUGH THE CWA. THE HIGHEST PROBABILITIES
OF PRECIPITATION WITH THIS SYSTEM LOOK TO OCCUR LATE WEDNESDAY NIGHT
INTO THURSDAY.

AS FOR TEMPERATURES...WENT NEAR/ABOVE NUMERICAL MODEL GUIDANCE AS
CLIMATOLOGY HAS BEEN TRENDING VALUES TOO LOW. AFTERNOON TEMPERATURES
IN THE UPPER 80S TO LOWER 90S SEEMS REASONABLE BASED ON THE PATTERN
FOR THE LONG TERM PERIOD. COOLER READINGS CAN BE EXPECTED ON
THURSDAY AS THE AFOREMENTIONED FRONTAL BOUNDARY AND PRECIPITATION
MOVE THROUGH THE AREA.

.AVIATION...

COMPLEX OF THUNDERSTORMS IN NEBRASKA STILL EXPECTED TO MOVE SOUTHEAST
AND IMPACT THE TAF SITES PRIMARILY IN THE 03Z-08Z TIME FRAME WITH MVFR
AND POSSIBLY BRIEF IFR VSBYS IN HEAVIER RAIN. ONCE THE COMPLEX
PASSES THROUGH...FEEL THERE MAY BE A BREAK IN PRECIP/LOWER VSBYS
AND CIGS INTO FRIDAY AFTERNOON...WITH A BETTER CHANCE JUST BEYOND
00Z/16. WINDS WILL BE SOUTH/SOUTHEASTERLY...BUT ANY OUTFLOW
BOUNDARIES WILL HAVE A SIGNIFICANT IMPACT ON SHORT TERM DIRECTION
AND SPEED.

.TOP WATCHES/WARNINGS/ADVISORIES...
NONE.
