AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
356 PM CDT THU SEP 6 2012

...UPDATED FOR SHORT TERM DISCUSSION...

.SYNOPSIS...
ISSUED AT 1043 PM CDT WED SEP 5 2012

THE 06.00Z 250 HPA SYNOPTIC MAP SHOWED FAIRLY STRONG FLOW ACROSS THE
NORTHERN 2/3RDS OF THE COUNTRY WITH MANY RAOB SITES REPORTING WINDS
BETWEEN 50 KT AND 75 KT. A FEW JET STREAKS WERE NOTED ACROSS CENTRAL
CALIFORNIA, THE MIDWEST, AND FINALLY ACROSS SOUTHEAST CANADA WITH WINDS
IN THE 75 KT TO 80 KT RANGE. AT 500 HPA, SOME MID LEVEL MOISTURE ADVECTION
WAS NOTED DOWNSTREAM OF A 579 DM CYCLONE LOCATED ACROSS THE EASTERN
PACIFIC. AN LONGITUDINALLY (WEST TO EAST) ELONGATED 591 DM ANTICYCLONE
WAS NOTED FROM THE DESERT SOUTHWEST EASTWARD ACROSS THE LONE STAR STATE.
A DEEP 550 DM CYCLONE WAS NOTED ACROSS NE MANITOBA WITH SEVERAL SHORTWAVE
TROFS ASSOCIATED WITH THIS PRESSURE PERTURBATION LOCATED ACROSS THE
CANADIAN PRAIRIES AND EXTENDING SOUTHWARD ACROSS THE INTERNATIONAL BORDER.
CYCLONIC FLOW WAS ALSO NOTED EAST OF FLORIDA. THE KDDC RAOB SHOWED SOME
MID LEVEL MOISTURE FROM 550 HPA TO 450 HPA. AT 700 HPA, FAIRLY COLD
TEMPERATURES IN THE 0 DEG C TO -3 DEG C RANGE WERE NOTED IN THE WAKE
OF A COLD FRONT ACROSS THE CENTRAL CANADIAN PRAIRIES. CLOSER TO KANSAS,
VALUES OF 11 DEG C TO 12 DEG C WERE NOTED ACROSS KDDC COUNTRY. CYCLONIC
FLOW WAS NOTED ACROSS THE NORTHEASTERN GULF OF MEXICO IN ASSOCIATION
WITH INVEST 90L. AT 850 HPA, THE WARMEST LOW LEVEL TEMPERATURES WITH
VALUES IN THE LOWER 30S DEG C RANGE EXTENDED ACROSS THE ROCKIES AND
INTO THE GREAT BASIN. VALUES ACROSS KANSAS WERE FAIRLY SEASONAL WITH
MANY RAOBS SITES IN THE LOWER 20S DEG C ACROSS THE CENTRAL PLAINS. AT
THE SURFACE, A STATIONARY BOUNDARY WAS NOTED ACROSS TEXAS AND OKLAHOMA
WITH DEWPOINTS IN THE 60S DEG F AND 70 DEG F SOUTH OF SAID BOUNDARY.
INVEST 90L WAS SE OF NEW ORLEANS AND A FEW FISH STORMS WERE LOCATED
ACROSS THE ATLANTIC BASIN.

&&

.SHORT TERM...(THIS EVENING THROUGH TOMORROW)
ISSUED AT 349 PM CDT THU SEP 6 2012

A SHORTWAVE TROUGH WAS APPROACHING THE NORTHERN PLAINS EARLY THIS
AFTERNOON, WITH THE ASSOCIATED COLD FRONT MOVING INTO SOUTHEAST
WYOMING AND THE WESTERN NEBRASKA PANHANDLE AS OF 20Z. THE SURFACE
CYCLONE WAS NOTED OVER NORTHERN NEBRASKA AND A DRYLINE EXTENDED
SOUTHWESTWARD FROM THE LOW INTO NORTHWEST KANSAS. LOW LEVEL
MOISTURE ADVANCED NORTHWARD INTO KANSAS TODAY AS LEE TROUGHING
DEVELOPED IN ADVANCE OF THE UPPER-LEVEL TROUGH. THIS ALSO ALLOWED
SURFACE TEMPERATURES TO WARM INTO THE MID TO UPPER 90S. SURFACE
BASED CAPE VALUES RANGED FROM 1500 TO 2000 K/JG EARLY THIS AFTERNOON.
THE VERTICAL WIND SHEAR PROFILE WAS FAVORABLE FOR MID-LEVEL
ROTATION WITH THE STORMS WITH 0-6 KM SHEAR RANGING FROM 30 TO 40
KTS. UPPER-LEVEL WIND SHEAR (6-11 KM) WAS ALSO RESPECTABLE AT
AROUND 30 KTS. GIVEN THESE CONDITIONS, HAIL AS LARGE AS GOLFBALLS
OR EVEN TENNIS BALLS IS POSSIBLE. GIVEN THE HIGH CLOUD BASES,
STRONG DOWNBURST WINDS ARE ALSO POSSIBLE WITH GUSTS AS HIGH AS 70
MPH. GIVEN THE MODEST MID-LEVEL FORCING, THE STORMS MAY STAY
SCATTERED, BUT ANY COLD POOL GENERATION COULD ALLOW THE INDIVIDUAL
STORMS TO GROW UPSCALE INTO LINE SEGMENTS/BOWS.

LATER TONIGHT AND EARLY FRIDAY, THE MAIN UPPER-LEVEL SHORTWAVE
TROUGH WILL APPROACH KANSAS. SO AFTER A LULL OVERNIGHT, MORE SHOWERS
AND THUNDERSTORMS ARE POSSIBLE, BUT THESE WILL PROBABLY NOT BE
SEVERE AND SHOULD BE ELEVATED IN NATURE. THIS ACTIVITY WILL PROBABLY
LINGER INTO EARLY AFTERNOON IN SOUTH CENTRAL KANSAS. TEMPERATURES
WILL BE MUCH COOLER FRIDAY WITH HIGHS IN THE UPPER 70S. HIGH WINDS
ARE EXPECTED DURING THE FIRST PART OF FRIDAY GIVEN THE EXPECTED
STRONG PRESSURE GRADIENT BEHIND THE FRONT. THEREFORE, A WIND ADVISORY
WAS ISSUED FOR ALL OF CENTRAL AND SOUTHWEST KANSAS.

.LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 204 PM CDT THU SEP 6 2012

UPPER LEVEL TROUGH WILL CROSS INTO THE MISSISSIPPI VALLEY FRIDAY
NIGHT AS AN AREA OF HIGH PRESSURE AT THE SURFACE BEGINS TO BUILD
INTO THE CENTRAL PLAINS. BY 12Z SATURDAY THE CENTER OF THIS SURFACE
HIGH IS FORECAST TO BE LOCATED IN NORTHWEST KANSAS. THIS HIGH THEN
MOVES SLOWLY SOUTHEAST WITH THE SURFACE RIDGE AXIS FORECAST TO
BE LOCATED NEAR SOUTH CENTRAL KANSAS BY 12Z SUNDAY. GIVEN CLEAR
SKIES AND LIGHT WINDS NEAR THE CENTER OF THIS HIGH WILL UNDERCUT THE
COOLEST GUIDANCE IN THESE TWO AREAS FRIDAY NIGHT AND SATURDAY NIGHT.
AT THIS TIME WOULD NOT BE SURPRISED TO SEE A FEW AREAS FALLING BACK
INTO THE MID 40S ACROSS NORTH CENTRAL OR WEST CENTRAL KANSAS FRIDAY
NIGHT. SATURDAY NIGHT THE COOLER TEMPERATURES MAY BE LOCATED ACROSS
SOUTH CENTRAL KANSAS WITH LOWS BOTTOMING OUT NEAR 50. AS FOR HIGHS
ON SATURDAY WILL STAY CLOSE TO THE PREVIOUS FORECAST GIVEN THAT THE
GFS, ECMWF AND NAM 850MB TEMPERATURES AT 00Z SUNDAY VARIED FROM
AROUND 15 IN SOUTH CENTRAL KANSAS TO THE LOWER 20S NEAR THE COLORADO
BORDER.

ON SUNDAY AN UPPER LEVEL RIDGE WILL BUILD EAST ACROSS THE ROCKIES AS
A TROUGH OF LOW PRESSURE AT THE SURFACE DEVELOPS ALONG THE LEE OF
THE ROCKIES. ENHANCED WESTERLY DOWNSLOPE IS EXPECTED AND 850-700MB
TEMPERATURES WILL BEGIN TO WARM. THIS WARMING TREND WILL CONTINUE
THROUGH EARLY NEXT WEEK AND BASED ON THE FORECAST 850MB TEMPERATURES
AT 00Z TUESDAY IT STILL APPEARS THAT HIGHS REBOUNDING BACK INTO THE
90S EARLY NEXT WEEK STILL LOOKS ON TRACK. IN ADDITION TO THESE
WARMER TEMPERATURES DRIER AIR WILL ALSO BE RETURNING TO WESTERN
KANSAS WHICH WILL RESULT IN AN INCREASE IN FIRE DANGER LEVEL BY
MONDAY AFTERNOON.

ON TUESDAY A COLD FRONT WILL MOVE SOUTH TOWARDS WESTERN KANSAS AS
AN UPPER LEVEL TROUGH EXITS THE ROCKIES AND MOVES OUT INTO THE
NORTHERN PLAINS. AHEAD OF THIS FRONT IT WILL BE ANOTHER WARM DAY
WITH 850MB TEMPERATURES CONTINUING TO SUPPORT HIGHS IN THE 90S. IN
ADDITION GIVEN THE INSTABILITY THERE WILL ALSO BE A CHANCE FOR
THUNDERSTORMS AS WELL TUESDAY NIGHT AS THIS COLD FRONT CROSSES
SOUTHWEST KANSAS. BY EARLY WEDNESDAY THE COLD FRONT IS FORECAST TO
BE LOCATED ACROSS THE PANHANDLE OF TEXAS AND OKLAHOMA. TEMPERATURES
MID WEEK ARE EXPECTED TO RANGE FROM THE MID 70S TO LOWER 80S GIVEN
THE EXPECTED CLOUD COVER AND 925-850MB TEMPERATURES BEHIND THE COLD
FRONT.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON)
ISSUED AT 1235 PM CDT THU SEP 6 2012

SOUTH WINDS AT 10 TO 15KTS WILL PERSIST THROUGH 11Z-12Z FOLLOWED BY A
WIND SHIFT TO THE NORTH AND INCREASE IN SPEED TO 25-30KTS AS A
COLD FRONT PASSES. THUNDERSTORMS ARE POSSIBLE IN VICINITY OF THE
TAFS (DDC/GCK/HYS) BETWEEN 22Z AND 03Z. THESE STORMS COULD CONTAIN
STRONG WIND GUSTS AND HAIL.
