Severe Thunderstorm Warning 139, NWS Dodge City, KS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
148 PM CDT MON JUL 14 2003

DAYS 1-2...

THE MAIN FORECAST CHALLENGE IS WHEN AND WHERE ANY PRECIPITATION
MIGHT FALL.  NO QUESTION THE HOT REGIME WILL CONTINUE, BUT WHERE
THERE WILL BE ENOUGH UPPER ENERGY TO SUPPORT ANY SURFACE BASED
CONVECTION WILL BE THE QUESTION TO DISCERN.

THE LATEST SURFACE MAP ANALYSIS FROM 18Z SHOWED A STRONG WARM (HOT)
FRONT FROM LOW PRESSURE CENTER BETWEEN KPIR AND KHON, STRETCHING
SOUTHEAST TO NEAR KMEM, BEFORE ARCHING EAST THEN NORTHEAST AS
STATIONARY FRONT TO NEAR KJFK.  A WEAK COLD FRONT WAS FORMING
SOUTHWEST FROM THE LOW PRESSURE THROUGH NORTHWEST KANSAS INTO NEW
MEXICO NEAR KABQ.  A FEW RECORD HIGH TEMPS COULD STILL BE SET THIS
AFTERNOON, AS THE LOW LEVEL WARM AIR ADVECTION AHEAD OF THE FRONT IS
VERY IMPRESSIVE.  AS THIS COLD FRONT RUNS INTO A STRONG WARM
SOUTHWEST FLOW ACROSS WESTERN KANSAS, THERE IS AT LEAST A SLIGHT
CHANCE FOR SOME SURFACE BASED THUNDERHEADS LATE TODAY AND THIS
EVENING.  THESE SHOULD BE HIGH BASED AND LOW PRECIPITATION PRODUCERS,
AND NEAR OR JUST AHEAD OF THE FRONTAL POSITION.  WILL GO WITH 20 POPS
FOR ALL BUT THE SOUTHEAST MOST ZONES UNTIL 04Z.

BEST MODEL INITIALIZATION FROM 12Z WAS THE ETA/MESOETA, FOLLOWED
CLOSE BY THE NGM.  WILL FOLLOW THE ETA FOR POPS ON TUESDAY, WITH 20
POPS IN WEST LATE IN THE DAY AND INTO THE EARLY EVENING.

LOW TEMPERATURES WILL CONTINUE TO RUN BELOW AFTERNOON DEW POINT
LEVELS AS THE BOUNDARY LAYER DRIES OUT LATE IN THE DAY.  HIGHS WILL
STILL BE HOT, BUT THINK TODAY WILL END UP BEING THE HOTTEST DAY OF
THE NEXT THREE DAYS.

DAYS 3-7...

LARGE, SPRAWLING UPPER RIDGE WILL PERSIST THROUGHOUT THE PERIOD WITH
500MB GEOPOTENTIAL HEIGHTS BREACHING 600 DAM VERY NEAR THE FCST AREA
A COUPLE OF DAYS THIS WEEK AS HIGH WOBBLES EAST A BIT.  A
PERSISTENCE FORECAST OF TEMPS NEAR 100F LOOK QUITE GOOD AND WITH
VERY STABLE MID-UPPER LEVELS IN VICINITY OF UPPER HIGH, WILL
CONTINUE WITH NO POPS OVER THE AREA.  LATEST GFS SHOWS SIGNAL OF
FLATTENING IN RIDGING BY DAY 7, HOWEVER A SIGNAL LIKE THIS IS
EXTREMELY DIFFICULT TO FILTER OUT FROM ALL THE NOISE FROM
CONVECTION, S/WV PERTURBATIONS AROUND THE UPPER HIGH, ETC. THAT
MODELS GENERATE IN THAT TIME FRAME.  UNTIL IT BECOMES MORE CLEAR
THAT UPPER RIDGING WILL BREAK DOWN SOME NEXT WEEK, WILL GO NEAR/NEAR
FOR TEMP/PCPN IN THE 8-10 DAY.
