What forecasters said that day

NWS Wichita, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 22, 3:11 PM CDT, 5 hours 8 minutes earlier.

Area forecast discussion, Jul 22, 3:11 PM CDT, 5 hours 8 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
311 PM CDT SUN JUL 22 2007

.DISCUSSION...
FORECAST CONCERNS...
CONVECTIVE CHANCES/TRENDS MONDAY AND MONDAY NIGHT...

DIURNAL CONVECTION WILL CONTINUE TO PERCOLATE ACROSS THE FLINT
HILLS AND SOUTHEAST KANSAS THROUGH THE EARLY EVENING...BEFORE
WANING AFTER SUNSET. WILL ONLY CARRY ISOLATED MENTION IN GRIDS
AFTER 00Z. A MORE INTERESTING SCENARIO MAY EVOLVE ON MONDAY AS
UPPER SHORTWAVE CURRENTLY MOVING ACROSS THE UPPER MIDWEST DIVES
SOUTH-SOUTHWEST ACROSS THE LOWER MISSOURI VALLEY AND INTO KANSAS.
MOISTURE AND INSTABILITY WILL REMAIN IN PLACE ON THE SOUTHERLY
LOW LEVEL FLOW ACROSS THE AREA...WHILE UPPER LEVEL NORTH TO
NORTHEAST WINDS WILL INCREASE WITH THE APPROACHING SHORTWAVE.
DESPITE RELATIVELY WEAK MID LEVEL WINDS...WITH THE PROGGED
DIRECTIONAL DEEP LAYER SHEAR AND ML CAPE VALUES AROUND 2700
J/KG...SUGGEST A FEW ROWDY MARGINALLY SEVERE STORMS WILL BE
POSSIBLE MONDAY AFTERNOON/EVENING. DESPITE THE GFS SUFFERING
FROM CONVECTIVE FEEDBACK ISSUES...ITS GENERAL SOLUTION IS ALSO
SUPPORTED BY THE NAM...WHICH WOULD FAVOR THE BEST CHANCE FOR THIS
CONVECTION TO AFFECT CENTRAL KANSAS. EVEN SO...THE INTER-OFFICE
FORECAST CONFIDENCE WAS ONLY HIGH ENOUGH TO PAINT MODEST CHC40
POPS ACROSS THIS AREA FOR NOW. PRECIPITABLE WATER VALUES OF
1.75-2.00 INCHES SUGGESTS HEAVY RAIN POTENTIAL AS WELL...AND WILL
ALSO MENTION THIS IN THE HAZARDOUS WEATHER OUTLOOK.

OTHERWISE...THE UPPER RIDGE AXIS WILL STRENGTHEN FROM THE NORTHERN
HIGH PLAINS INTO THE UPPER MIDWEST INTO MID-WEEK...WITH THE SHORT
RANGE MODELS SUGGESTING ANOTHER SHORTWAVE TROF WILL DROP SOUTH
ACROSS THE AREA WEDNESDAY NIGHT. CHANCES FOR CONVECTION ON TUESDAY
AND WEDNESDAY LOOK TO BE MORE ISOLATED AGAIN...MAINLY DIURNALLY
DRIVEN...AND FOR NOW STAYED WITH STATUS QUO...SLIGHTS ON TUESDAY
AND DRY ON WEDNESDAY. WILL LET DAY NIGHT SHIFT REFINE THESE PERIODS
BASED ON LATER MODEL RUNS.

THE MEDIUM RANGE MODELS WERE IN GENERAL AGREEMENT WITH THE 00Z
RUNS...IN SHOWING A STRONGER MID/UPPER LEVEL TROF DROPPING
SOUTHEAST ACROSS THE MIDWEST AND INTO THE MEAN LONGWAVE TROF
ACROSS THE OHIO VALLEY/EAST BY FRIDAY. THE ECM HAS BACKED OFF
OR DELAYED THIS SOMEWHAT WITH 12Z RUN...WHILE THE NEW GFS REMAINS
MORE STEADFAST. THE HPC GUIDANCE GENERALLY FOLLOWED THE GFS AND
FORECAST CONSENSUS WAS TO LEAN IN THIS DIRECTION...THOUGH PERHAPS
A BIT SLOWER WITH SOUTHWARD MOVE OF THE FRONT. THAT SAID...HAVE
INTRODUCED SLIGHT POPS FOR FRIDAY NIGHT/SATURDAY ACROSS MUCH OF
THE AREA...PER COLLABORATION.

DARMOFAL

&&

.AVIATION...
LATEST VISIBLE IMAGERY IS ONCE AGAIN SHOWING A SCATTERED CUMULUS
FIELD ACROSS MOST OF THE FORECAST AREA WITH THE MOST CONCENTRATED
AREA IN THE FLINT HILLS. INSTABILITY AXIS IS CURRENTLY OVER SOUTH
CENTRAL KANSAS WHERE THINGS ARE HEATING UP MORE QUICKLY DUE TO
SLIGHTLY LOWER DEWPOINTS. LATEST SURFACE ANALYSIS IS STILL SHOWING
DEWPOINTS IN THE 70 TO 75 DEGREE RANGE IN SOUTHEAST KANSAS SO WE
WOULD ANTICIPATE THE INSTABILITY TO CONTINUE INCREASING ACROSS
THAT REGION. THIS WILL RESULT IN MORE WIDELY SCATTERED
THUNDERSTORM DEVELOPMENT THIS AFTERNOON...ESPECIALLY IN THE FLINT
HILLS AND SOUTHEAST KANSAS. WE WILL BE MENTIONING VCTS IN THE
SALINA...WICHITA AND CHANUTE TAF SITES. OTHERWISE...VFR CONDITIONS
WILL PREVAIL.
