AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DODGE CITY KS
548 PM CDT TUE MAY 7 2013

...UPDATED FOR AVIATION...

.SYNOPSIS...
ISSUED AT 1159 AM CDT TUE MAY 7 2013

THE 12Z UPPER AIR ANALYSIS DEPICTS THREE UPPER LEVEL LOWS LOCATED
ACROSS THE UNITED STATES WITH A WEAK UPPER LEVEL RIDGE POSITIONED
ACROSS THE SOUTHERN PLAINS. ONE UPPER LEVEL LOW IS LOCATED ACROSS
THE DESERT SOUTHWEST, A SECOND ONE POSITIONED ACROSS THE NORTHERN
PLAINS, AND A THIRD ONE ACROSS THE SOUTHEAST UNITED STATES. A 50+
KNOT 250MB JET EXTENDS FROM SOUTHERN CALIFORNIA, THROUGH THE FOUR
CORNERS REGION, THEN INTO NORTHERN TEXAS. ALSO IN THE UPPER
LEVELS, A WEAK SHORTWAVE HAS MOVED AROUND THE PERIPHERY OF THE
UPPER LEVEL LOW ACROSS THE DESERT SOUTHWEST AND UP THE WEST SIDE
OF THE UPPER LEVEL RIDGE. IT IS CURRENTLY LOCATED ACROSS THE
CENTRAL HIGH PLAINS. THIS FEATURE HAS BROUGHT COPIOUS AMOUNTS OF
MOISTURE TO THE MID LEVELS OF THE ATMOSPHERE AND HAS CONTRIBUTED
TO THE SHOWERS AND ISOLATED THUNDERSTORMS OBSERVED DURING THE
EARLY MORNING HOURS. LEE TROUGHING BECOMES PREVALENT ACROSS
EASTERN COLORADO AS YOU MAKE YOUR WAY DOWN TO THE SURFACE WITH
SOUTHERLY WINDS FELT ACROSS SOUTHWEST KANSAS. THIS SOUTHERLY FLOW
HAS BROUGHT UP A TONGUE OF 50 DEGREE DEWPOINTS ACROSS PARTS OF
WESTERN KANSAS AND MAY BE THE FOCAL POINT WHERE STORMS MAY FORM
LATER THIS AFTERNOON INTO THIS EVENING. SKIES ARE MOSTLY CLOUDY
ACROSS CENTRAL AND SOUTH CENTRAL KANSAS THIS MORNING WITH MOSTLY
CLEAR SKIES OBSERVED ACROSS WESTERN KANSAS.

&&

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 125 PM CDT TUE MAY 7 2013

AN UPPER LEVEL LOW WILL CONTINUE TO SPIN EASTWARD DURING THE SHORT
TERM PERIOD AND BE POSITIONED ACROSS THE FOUR CORNERS REGION
TONIGHT. THIS AREA OF LOW PRESSURE EXTENDS DOWN TO THE MID LEVELS OF
THE ATMOSPHERE WITH LEE TROUGHING BECOMING EVIDENT ACROSS EASTERN
COLORADO AS YOU HEAD TO THE SURFACE. AT THE SURFACE, AN AREA OF LOW
PRESSURE WILL BE FOUND ACROSS THE KS/CO BORDER THIS AFTERNOON INTO
THIS EVENING WITH A DRYLINE LOCATED ACROSS FAR WESTERN KANSAS. THIS
WILL ALLOW SOUTHERLY WINDS TO CONTINUE ACROSS WESTERN KANSAS BACKING
TO THE SOUTHEAST AHEAD OF THE DRYLINE. STRONG TO SEVERE
THUNDERSTORMS WILL BE POSSIBLE LATE THIS AFTERNOON INTO THE EARLY
EVENING AS THE ATMOSPHERE BECOMES UNSTABLE ACROSS SOUTHWEST KANSAS.
SOME OF THE KEY INGREDIENTS TO CONVECTIVE INITIATION INCLUDE A DRY
LINE DEVELOPING AND EXTENDING FROM SCOTT CITY TO LIBERAL, 0-6 KM
SHEAR IN THE 40 TO 50 KNOT RANGE, CAPE VALUES EXCEEDING 1000 J/KG, A
TONGUE OF 50+ DEWPOINTS AT THE SURFACE, AND MOSTLY CLEAR SKIES
ALLOWING FOR AMPLE HEATING ACROSS MUCH OF SOUTHWEST KANSAS. SOME
LIMITATIONS TO STORM DEVELOPMENT WILL BE THE LACK OF UPPER LEVEL
SUPPORT, SURFACE DEWPOINTS ONLY REACHING INTO THE 50S, AND IN TURN
ONLY MODEST CAPE VALUES. ANY STORMS THAT DO DEVELOP WILL HAVE THE
CAPABILITY OF PRODUCING UP TO GOLF BALL SIZED HAIL AND WINDS UP TO
70 MPH. TORNADO THREAT SHOULD REMAIN LOW DUE TO HIGH LCL'S ACROSS
WESTERN KANSAS. THESE STORMS WILL DECREASE IN INTENSITY AFTER SUNSET
AND MOVE INTO CENTRAL AND SOUTH CENTRAL KANSAS BY SUNRISE TOMORROW.
SKIES MAY CLEAR ACROSS WESTERN KANSAS OVERNIGHT WITH CLOUDY
CONDITIONS CONTINUING ACROSS CENTRAL AND SOUTH CENTRAL KANSAS. LOWS
TONIGHT ARE FORECASTED TO RANGE FROM AROUND 50 DEGREES ACROSS THE
KS/CO BORDER TO UPPER 50S ACROSS CENTRAL AND SOUTH CENTRAL KANSAS.

ON WEDNESDAY, AN UPPER LEVEL LOW WILL CONTINUE TO MOVE EASTWARDS
FROM THE 4 CORNERS REGION INTO THE SOUTHERN AND CENTRAL ROCKIES. 250
MB FLOW WILL BECOME INCREASING DIFLUENT THROUGH THE DAY ACROSS SW
KANSAS. AT THE SURFACE...LEE CYCLOGENESIS WILL CONTINUE THROUGH THE
DAY WITH A WARM FRONT BISECTING THE FORECAST AREA. SHORT RANGE
MODELS ALSO SUGGEST A DRY LINE TO BE LOCATED ACROSS FAR SOUTHWESTERN
KANSAS. SOUTH OF THE FRONT, A WARM SECTOR ENVIRONMENT IS EXPECTED
WITH DEWPOINTS REACHING INTO THE UPPER 50S. CAPE AROUND 2000 J/KG
WILL LEAD TO AN UNSTABLE ENVIRONMENT WITH 0-6 KM SHEAR REACHING TO
AROUND 35-40 KTS. FORECAST SOUNDINGS SHOW UPPER LEVEL WINDS BACKING,
WHICH SUGGESTS MAYBE MORE OF AN HP SUPERCELL THREAT. LOCAL HAIL
RESEARCH SUGGESTS THAT HAIL UP TO THE SIZE OF TENNIS BALLS IS
POSSIBLE WITH GOLFBALL TO HEN EGG BEING MORE LIKELY. THERE WILL BE
TWO AREAS OF CONCERN FOR SEVERE WEATHER ...ONE ACROSS THE KS/OK
BORDER AHEAD OF THE DRYLINE AND THE OTHER AREA ACROSS THE NORTHERN
ZONES WHERE THE WARM FRONT LOOKS TO BE POSITIONED. IN ADDITION,
THERE IS A SLIGHT RISK DEPICTED FROM SPC IN THIS SAME AREA. THERE
WILL BE A SLIGHT CHANCE OF AN ISOLATED TORNADO BUT THE MAIN CONCERN
WILL BE LARGE HAIL AND DAMAGING WINDS. AS FOR TEMPERATURES, HIGHS
TOMORROW ARE FORECASTED TO RANGE FROM THE LOWER 70S ACROSS WEST
CENTRAL KANSAS TO LOWER 80S ACROSS FAR SOUTHWEST KANSAS.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 219 PM CDT TUE MAY 7 2013

NAM, GFS, ECMWF WERE ALL IN DECENT AGREEMENT WITH AN UPPER
TROUGH, 400MB POTENTIAL VORTICITY ANOMALY, CROSSING THE WEST
CENTRAL HIGH PLAINS WEDNESDAY NIGHT. THE CONVECTION WHICH HAD
DEVELOPED AHEAD OF THIS WAVE IS EXPECTED TO CONTINUE. WILL FOCUS
THE BETTER CHANCES FOR OVERNIGHT CONVECTION NORTH OF THE SURFACE
FRONT WHERE LOW LEVEL MOISTURE AXIS AND BETTER FORCING IS
EXPECTED.

ON THURSDAY AND THURSDAY NIGHT AN UPPER LEVEL TROUGH WILL SLOWLY
CROSS THE CENTRAL PLAINS AS A RIDGE OF HIGH PRESSURE AT THE
SURFACE STARTS TO MOVE INTO NORTHWESTERN KANSAS. ALONG AND AHEAD
OF THIS UPPER TROUGH SOME MID LEVEL MOISTURE AND INSTABILITY WILL
EXIST. AS A RESULT WILL KEEP CLOUDS AND A CHANCE FOR PRECIPITATION
GOING ACROSS WESTERN KANSAS UNTIL THIS UPPER TROUGH MOVES INTO
OKLAHOMA EARLY FRIDAY. GIVEN THE EXPECTED CLOUD COVER AND POSSIBLE
PRECIPITATION ON THURSDAY WILL TREND TOWARDS THE COOLER 850MB 00Z
FRIDAY MIXDOWN TEMPERATURES WHICH SUGGESTED HIGHS RANGING FROM THE
MID 60S TO THE LOWER 70S.

ON FRIDAY AFTERNOON HIGH PRESSURE AT THE SURFACE WILL BUILD
ACROSS WESTERN KANSAS. 24HOUR 925-850MB TEMPERATURE TRENDS BETWEEN
00Z FRIDAY AND 00Z SATURDAY INDICATED A 2-3C WARMUP ACROSS WESTERN
KANSAS UNDER CLEARING SKIES. USING THIS AS A GUIDE THE PREVIOUS
FORECAST FOR TEMPERATURES STILL LOOKS ON TRACK WITH HIGHS
GENERALLY FROM 70 TO NEAR 73.

ON SATURDAY A COLD FRONT WILL CROSS WESTERN KANSAS AS A NORTHERN
BRANCH UPPER LEVEL TROUGH EXITS CENTRAL CANADA AND CROSSES THE
UPPER MISSISSIPPI VALLEY. AHEAD OF THIS FRONT TEMPERATURES ARE
EXPECTED TO ONCE AGAIN CLIMB BACK INTO THE 70S WHILE ACROSS NORTH
CENTRAL KANSAS AFTERNOON TEMPERATURES WILL FALL BACK INTO THE 60S.

LATE THIS WEEKEND AND EARLY NEXT WEEK AN UPPER LEVEL RIDGE WILL
BEGIN TO MOVE EAST ACROSS THE WESTERN UNITED STATES. DOWNSLOPE
FLOW IS EXPECTED TO IMPROVE AS THE NORTHWESTERLY FLOW BACKS MORE
TO THE WEST. THE GFS AND ECMWF WERE BOTH IN DECENT AGREEMENT WITH
SURFACE LEE TROUGH DEVELOPMENT AND 850MB TEMPERATURES CLIMBING
THROUGH THE TEENS INTO THE LOW TO MID 20S. HIGHS REBOUNDING BACK
INTO THE 80S STILL LOOKS ON TRACK.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING)

EXPECT VFR CONDITIONS INTO WEDNESDAY. A FEW SEVERE THUNDERSTORMS
ARE POSSIBLE TONIGHT FROM 00Z-06Z WITH THE BEST CHANCES IN THE
KHYS AREA. SOUTHEAST WINDS OF 15-25KT WILL DECREASE TO AROUND
10-15KT AFTER 10Z.
