Damaging Winds in Kansas, July 26, 2006

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
724 PM CDT WED JUL 26 2006

.UPDATE...

LATEST SURFACE ANALYSIS INDICATES A LOW-LEVEL BOUNDARY SURGING
SOUTHWARD WHICH WAS ALSO BEING PICKED UP BY KICT 88D. MLCAPES
RANGING FROM 1000-2000J/KG OVER THE AREA AND MINIMAL CIN SUPPORTS
A CONTINUATION OF ACTIVITY THROUGH THE LATE EVENING HRS. SHEAR IS
WEAK BUT STILL CANNOT RULE OUT A FEW STRONG TO POSSIBLY SEVERE
STORMS FROM MODEST INSTABILITY. MEANWHILE...AREAS OF CONVECTION
CURRENTLY AFFECTING SOUTH CENTRAL KANSAS COULD CAUSE AN OUTFLOW
BOUNDARY TO SURGE NORTHWARD AND ENHANCE THE CONVERGENCE ALONG THE
TWO INTERSECTING BOUNDARIES...THEREFORE WE ANTICIPATE A POSSIBLE
INCREASE OF THUNDERSTORM COVERAGE DURING THE NEXT FEW HRS. THE
ACTIVITY COULD LINGER PAST MIDNIGHT ESPECIALLY IF 850MB PROFILERS
CONTINUE TO SHOW CONVERGENCE OVER SOUTHERN KANSAS. DUE TO THE SLOW
STORM MOVEMENT LOCALLY HEAVY RAINFALL COULD BECOME A CONCERN LATER
ON.

DISCUSSION...

TONIGHT-THURSDAY NIGHT:
FORECAST FOCUS IS ON BEHAVIOR OF NEARLY STATIONARY 850-MB FRONT DRAPED
IN SW-NE MANNER FROM TX PANHANDLE ACROSS SRN KS TO NRN MO. BOUNDARY TO
ASSUME MORE W-E ORIENTATION ACROSS SRN KS AS POSITIVELY-TILTED UPPER
DECK TROF...MOVING E/SE ACROSS NRN ROCKIES...VENTURES OVER NRN PLAINS
THU MORNING AT WHICH TIME ITLL SHEAR OUT. AMPLE SFC-700MB MOISTURE
RESIDES ACROSS FORECAST AREA & SFC-850MB CONVERGENCE...THOUGH FAIRLY
ANEMIC OVER ERN KS...APPEARS SUFFICIENT VICINITY TX/OK PANHANDLES TO
ASSIGN 25-35% CHANCES FOR TSRA TONIGHT WITH THE HIGHER POPS ASSIGNED
TO SW CORRIDOR WHERE CLOSER TO STRONGER LOWER-DECK CONVERGENT AXIS.
POP GRADIENT TO ASSUME MORE N-S ORIENTATION THURSDAY/THURSDAY NIGHT.

FRIDAY & FRIDAY NIGHT:
WITH AFORE-MENTIONED FRONTS DISSIPATING CONVERGENT AXIS LIKEWISE TO
DISSIPATE. AS SUCH TSRA CHANCES TO DIMINISH IN W-E MANNER. WITH
CONVECTIVE DEBRIS IN NEIGHBORHOOD FROM THURSDAY NIGHTS ACTIVITY
LOWERED FRIDAYS MAXES 3F ALL AREAS.

EXTENDED (SATURDAY-TUESDAY):
POTENTIALLY VERY HOT AND DRY CONDITIONS HIGHLIGHT THE EXTENDED
PERIOD. COULD BE LOOKING AT SOME RECORD HIGH MAXES AND HIGH MINS.
THINKING CURRENT NUMBERS REPRESENTED IN THE GRIDS ARE CONSERVATIVE.
HIGHS COULD CONCEIVABLY BE UPWARDS OF 105F...WITH OVERNIGHT LOWS
75-80F. SO A HEAT ADVISORY MAY BE NEEDED AS THE WEEKEND APPROACHES.

SYNOPTIC PATTERN WILL SHOWCASE A BROAD MID-UPPER LEVEL RIDGE OF HIGH
PRESSURE...WHICH SHOULD AMPLIFY AND SHIFT EAST...ALLOWING FOR HOT
AND RELATIVELY DRY AIR TO SHIFT EAST OVER CENTRAL PORTIONS OF THE
NATION. INCREASED AFTERNOON HIGHS A FEW DEGREES EACH DAY DURING THE
PERIOD. ALSO LOWERED DEWPOINTS...ESPECIALLY DURING THE
AFTERNOON...DUE TO LACK OF APPRECIABLE SOIL MOISTURE AND GOOD
MIXING. INCREASED AFTERNOON WIND SPEEDS AS WELL...AS LEE TROUGHING
STRENGTHENS ACROSS THE WESTERN HIGH PLAINS.

MODELS INDICATE A WEAKNESS IN THE RIDGE PROGRESSING ACROSS THE
PLAINS LATE WEEKEND THROUGH EARLY NEXT WEEK. THIS MAY SPREAD SOME
MID TO HIGH LEVEL CLOUDS ACROSS THE AREA...SO LET BACK ON THE
TEMPERATURE THROTTLE A BIT FOR EARLY NEXT WEEK. PROGGED SURFACE
FRONT MAY BE THREATENING PORTIONS OF CENTRAL KANSAS BY
MONDAY-TUESDAY...BUT DID NOT INSERT POPS YET.
