AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
546 PM CST SAT NOV 10 2012

...UPDATE TO AVIATION...

.DISCUSSION...

SHORT TERM (TONIGHT THROUGH SUNDAY)...

MAIN FOCUS FOR THE SHORT TERM IS ON THE APPROACHING LOW PRESSURE
SYSTEM AND ITS IMPACTS ON TEMPERATURES...WINDS...AND THE POTENTIAL
FOR STRONG TO SEVERE THUNDERSTORMS.

THE UPPER LEVEL TROUGH CONTINUED TO DEEPEN ACROSS THE ROCKY
MOUNTAINS THIS AFTERNOON AS A BROAD RIDGE STRETCHED ACROSS THE
EASTERN U.S. AS OF 22Z...THE SURFACE LOW WAS OVER FAR EASTERN
COLORADO...AND WILL TRACK NORTHEASTWARD INTO NORTHWEST KANSAS AND
SOUTHWEST NEBRASKA LATE THIS AFTERNOON INTO THIS EVENING. WHILE LOW-
AND MID-LEVEL CLOUDS STEADILY STREAMED INTO THE CWA WITH A FEW
SCATTERED ELEVATED SHOWERS THROUGH THE AFTERNOON...SKIES WERE CLEAR
ACROSS THE WESTERN HALF OF THE STATE FOR MUCH OF THE DAY UNTIL MID
AFTERNOON WHEN A FEW SHOWERS HAVE ALREADY BEGUN TO POP UP AHEAD OF
THE BOUNDARY. THIS FRONT WILL SLOWLY TRACK EASTWARD INTO KANSAS LATE
THIS AFTERNOON BEFORE PICKING UP ITS PACE A BIT AS IT GETS PUSHED
ALONG BY THE UPPER TROUGH WITH THE UPPER LOW SPINNING TOWARD THE
NORTHERN PLAINS. BEST INSTABILITY LATE THIS AFTERNOON INTO THIS
EVENING WILL BE FOCUSED GENERALLY ALONG AND EAST OF A DODGE CITY TO
PHILLIPSBURG LINE...WHICH IS ROUGHLY WHERE THE DRYLINE HAS SET UP. A
FEW CELLS HAVE ALREADY STARTED TO DEVELOP NEAR LA CROSSE KANSAS THIS
AFTERNOON. THUNDERSTORMS THAT DEVELOP INITIALLY ALONG THIS DRYLINE
WILL LIKELY BE MORE IN THE FORM OF DISCRETE CELLS BEFORE CONGEALING
MORE INTO A LINEAR STRUCTURE AS IT MOVES INTO NORTH CENTRAL AND
CENTRAL KANSAS. THE BEST AREA OF INSTABILITY SHOULD SEE CAPE VALUES
OF 800-1200J/KG...WITH A GREAT DEAL OF UNIDIRECTIONAL SHEAR EXPECTED
AS 0-6KM BULK SHEAR BECOMES UPWARDS OF AROUND 50 KTS. ONE LIMITING
FACTOR IS THE AMOUNT OF AVAILABLE MOISTURE...BUT ANY STORMS THAT
DEVELOP INTO CENTRAL KANSAS COULD HAVE THE CAPABILITY OF PRODUCING
DAMAGING WINDS UP TO 60 MPH...AND LARGE HAIL UP TO THE SIZE OF
QUARTERS. SHORT-TERM MODELS SHOW THE COLD FRONT ENTERING INTO NORTH
CENTRAL KANSAS BETWEEN 01Z-03Z...WITH A MORE LINEAR STRUCTURE IN THE
THUNDERSTORMS AS IT MOVES INTO THE FORECAST AREA. ONCE THE ACTIVITY
TRANSITIONS TO A LINE OF THUNDERSTORMS...THE MAIN SEVERE THREAT WILL
DAMAGING WINDS. THIS ACTIVITY SHOULD WEAKEN IN SEVERITY AFTER
MIDNIGHT AS INSTABILITY STEADILY WEAKENS. MODELS SHOW OVERNIGHT INTO
SUNDAY MORNING AN AREA OF STRATIFORM SHOWERS DEVELOPING BEHIND THE
FRONT...WITH ALL PRECIPITATION EXITING FROM WEST TO EAST SUNDAY
MORNING INTO EARLY AFTERNOON. AS COLD AIR FUNNELS IN BEHIND THIS
SYSTEM OVERNIGHT...THE PRECIPITATION SHOULD END BEFORE IT CAN
TRANSITION OVER TO SNOW. HOWEVER...CANNOT RULE OUT A FEW FLAKES
MIXING IN WITH THE LINGERING SHOWERS.

AS FOR TEMPERATURES...WE WILL START TO SEE THE LARGE GRADIENT IN
TEMPERATURES OVERNIGHT AS THE COLD FRONT STARTS TO SWEEP INTO THE
AREA. LOWS TONIGHT LOOK TO ONLY DROP INTO THE MID 50S OVER EAST
CENTRAL KANSAS WHILE COOLING DOWN INTO THE LOWER 30S OVER NORTH
CENTRAL KANSAS. THE SUNDAY HIGHS WON'T BE MUCH MORE THAN A COUPLE OF
DEGREES DIFFERENT FROM TONIGHTS LOWS AS THE COLD FRONT EXITS EAST OF
THE REGION SUNDAY MORNING. AS A RESULT...THERE WILL BE A NON-DIURNAL
TREND FOR SUNDAY TEMPERATURES.

WINDS AHEAD OF THE FRONT LATE THIS AFTERNOON THROUGH THIS EVENING
WILL REMAIN VERY GUSTY OUT OF THE SOUTH...WITH A WIND ADVISORY
REMAINING IN EFFECT FOR THE ENTIRE FORECAST AREA THROUGH MIDNIGHT.
WINDS WILL SHIFT TO THE NORTHWEST BEHIND THE FRONT...BUT ARE
EXPECTED TO STILL REMAIN BREEZY THROUGH THE DAY ON SUNDAY WITH
SUSTAINED WINDS OF 15-20MPH AND GUSTS UPWARDS OF 25MPH.

ACH

LONG TERM (SUNDAY NIGHT THROUGH SATURDAY)...

SUNDAY NIGHT AND MONDAY...THE UPPER LEVEL TROUGH WILL LIFT EAST-
NORTHEAST INTO THE GREAT LAKES AND MID MS RIVER VALLEY. THE STRONG
LOW-LEVEL CAA WILL ALLOW A RIDGE OF SFC HIGH PRESSURE TO BUILD
SOUTHEAST ACROSS THE AREA. CLEARING SKIES AND DIMINISHING
NORTHWEST WINDS WILL ALLOW OVERNIGHT LOWS TO DROP INTO THE MID TO UPPER
TEENS ACROSS NORTH CENTRAL KS...WITH LOWER TO MID 20S ACROSS
NORTHEAST AND EAST CENTRAL KS. THE SURFACE RIDGE WILL SHIFT EAST
OF THE CWA MONDAY AFTERNOON AND WINDS WILL BECOME WESTERLY. HIGHS
WILL WARM INTO THE MID TO UPPER 40S.

TUESDAY THROUGH THURSDAY...THE UPPER FLOW WILL BECOME ZONAL. EXPECT
DRY CONDITIONS WITH HIGHS IN THE MID 50S.

FRIDAY AND SATURDAY...A WEAK UPPER LEVEL TROUGH EMBEDDED WITHING THE
SOUTHERN STREAM UPPER JET WILL APPROACH THE SOUTHERN AND CENTRAL
PLAINS ON FRIDAY. I'M NOT TOO SURE ABOUT THE QUALITY OF THE MOISTURE
RETURN AHEAD OF THIS H5 TROUGH BUT THERE MAY BE ENOUGH MOISTURE
RETURN FOR A CHANCE OF SHOWERS FRIDAY INTO SATURDAY. THE SHOWERS
SHOULD END LATE SATURDAY AS A WEAK COLD FRONT MOVES EASTWARD
ACROSS THE CWA. HIGHS WILL CONTINUE TO BE IN THE MID TO UPPER 50S.
