AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
131 PM CDT MON MAY 24 2010

.DISCUSSION...

DAYS 1-2...

SEVERE WEATHER OPERATIONS COMMENCED AS OF 1830 UTC AS VERY INTENSE
MID LEVEL POTENTIAL VORTICITY ANOMALY...AND RESULTING UPWARD
VERTICAL MOTION CONTINUES TO OVERSPREAD A VERY MOIST AND UNSTABLE
LOWER TROPOSPHERE...WITH WIDESPREAD LOWER TO MID 60S DEWPOINTS
EAST OF THE LOW LEVEL CONVERGENCE AXIS. AS OF 1740 UTC...INITIAL
DEVELOPMENT OF SURFACE BASED CONVECTION WAS OCCURRING FROM
SOUTHWEST OF GOODLAND DOWN INTO THE CENTRAL OKLAHOMA PANHANDLE.
OTHER STORMS WILL DEVELOP ACROSS THE TEXAS PANHANDLE...WHICH WOULD
ORGANIZE AND MOVE RAPIDLY NORTHEAST INTO SOUTHWEST KANSAS. GIVEN
THE STRENGTH OF THE LOW LEVEL WINDS, LOW LEVEL MESOCYCLOGENESIS
WILL BE FAVORED WITH SUPERCELL STORMS. GIVEN THE LARGE AREA OF LOW
LEVEL MOISTURE AND CAPE THERE IS A FAIRLY LARGE THREAT AREA FOR
SEVERE STORMS AND TORNADOES. IT REMAINS UNCLEAR HOW LONG THE
CONVECTIVE MODE WILL BE SUPERCELLULAR...BUT BY LATE AFTERNOON AND
EARLY EVENING, AS MORE STORMS DEVELOP, THERE WILL LIKELY BE A
TRANSITION TO QUASI-LINEAR STRUCTURES. THAT BEING SAID, LOW LEVEL
MESOCYCLONES WILL STILL BE FAVORED WITH THE POSSIBILITY OF QLCS
(QUASI-LINEAR CONVECTIVE SYSTEM) TORNADOES AS THE THREAT AREA
SLOWLY SHIFTS EAST BY THE EARLY TO MID EVENING HOURS.

A WEAK COLD FRONT WILL MOVE INTO WESTERN KANSAS AS THE MAIN SYSTEM
LIFTS RAPIDLY NORTHEAST INTO THE NORTHERN PLAINS EARLY TOMORROW
MORNING. THIS FRONT WILL STALL OUT ACROSS SOUTHWEST KANSAS AS YET
ANOTHER WAVE ENTERS THE PICTURE TO THE SOUTHWEST...WHICH WILL
FAVOR LOW LEVEL CYCLOGENESIS ACROSS THE FAR SOUTHWEST SECTIONS OF
THE DDC FA. MORE SURFACE-BASED SEVERE STORMS ARE EXPECTED TOMORROW
AFTERNOON AND EVENING...WITH THE GREATEST THREAT BEING ACROSS THE
SOUTHWESTERN THIRD OF THE DDC FA...AND POINTS SOUTH OF THERE. WILL
INCREASE POPS TO 40-50 PERCENT OVER A LARGER PORTION OF THE DDC FA
GIVEN THIS LINE OF THINKING.

THIS WEAK WAVE WILL LIFT NORTHEAST INTO NORTHERN KANSAS AND
NEBRASKA LATE TOMORROW NIGHT INTO WEDNESDAY...BUT VERY MOIST LOW
LEVEL AIRMASS WILL REMAIN WITH DEWPOINTS IN THE LOWER TO MID 60S.
LOW LEVEL CYCLOGENESIS WILL AGAIN BE FAVORED ACROSS FRONT RANGE
AND LARAMIE RANGE WHICH WILL ALLOW WINDS TO INCREASE OUT OF THE
SOUTHEAST AGAIN...IN RESPONSE TO THE NEXT LARGER SCALE TROUGH
MOVING INTO THE INTERMOUNTAIN WEST REGION.

DAYS 3-7...

LITTLE CHANGE TO THE MEDIUM RANGE FORECAST WAS MADE THIS AFTERNOON,
AS A GENERAL EXPECTATION OF CONTINUED WARM AND DRY WEATHER WILL
BE IN PLACE FOR THURSDAY AND FRIDAY, AS WELL AS EVEN INTO SATURDAY
BEFORE A MORE SIGNIFICANT CHANCE OF THUNDERSTORMS AND POTENTIAL
SEVERE WEATHER RETURNS TO THE AREA BY LATE SATURDAY AND SATURDAY
NIGHT.

BY WEDNESDAY NIGHT THE MODELS ARE IN GREAT AGREEMENT EJECTING A
DEEPENED MID LEVEL LOW FROM THE NORTHERN PLAINS INTO SOUTH CENTRAL
KANSAS. WHILE SOUTHWEST FLOW REMAINS ESTABLISHED ALOFT ACROSS THE
HIGH PLAINS REGION. WITH TIME INTO WEDNESDAY NIGHT AND THURSDAY, THE
LARGE CYCLONE THAT REMAINS ANCHORED OFF THE NORTHWEST PACIFIC COAST
WILL HELP ALLOW HEIGHT RISES AND EVENTUALLY A DEVELOPED MID LEVEL
ANTICYCLONE FROM NEW MEXICO TO MINNESOTA.  WITH HIGH PRESSURE ALOFT,
THE MEDIUM RANGE PERIOD WILL BRING FAIRLY LIGHT WINDS BEFORE
SOUTHWEST FLOW ALOFT BECOME AGAIN ESTABLISHED BY SATURDAY.
INCREASING LOW LEVEL MOISTURE ADVECTION WILL RETURN ON SATURDAY WITH
INCREASING CHANCES FOR DRYLINE THUNDERSTORMS/MCS ACTIVITY SATURDAY
INTO SATURDAY NIGHT. A FRONTAL BOUNDARY WOULD BE BEST TIMED INTO THE
AREA AGAIN ON SUNDAY WITH CLOUDY A COOL CONDITIONS PROBABLY
FOLLOWING THE PASSAGE INTO SUNDAY NIGHT.

&&

.AVIATION...

STRONG SOUTHEAST WINDS WILL BE ONGOING THROUGH THE EVENING BEFORE
SOME DECOUPLING OCCURS, BUT A GRADIENT WILL ALSO BE IN PLAY. LATE
AFTERNOON AND EVENING WILL BRING SCATTERED STRONG TO SEVERE
THUNDERSTORMS THAT MAY AFFECT ANY AND ALL TERMINALS SITES.  TEMPOS
WILL BE USED FOR LATE AFTERNOON CONVECTIVE ACTIVITY, BEFORE A
PREVAILING TSRA MAY BE NEEDED IN THE EASTERN TERMINALS BY EARLY
EVENING.
