ANTICIPATED TO AFFECT MAINLY CENTRAL KS OVERNIGHT...ALONG/NORTH OF
QUASI-STATIONARY FRONTAL BOUNDARY. A FEW STORMS WILL BE POSSIBLE
ACROSS SOUTH-CENTRAL AND SOUTHEAST KS LATER TONIGHT...AS LOW-LEVEL
JET CONTINUES TO INCREASE AND VEER. ANTICIPATE CIGS TO GRADUALLY
DROP BY THURSDAY MORNING...ESPECIALLY BEHIND THE FRONT. CIGS MAY
GO LOWER THAN IFR IN DRIZZLE. ANOTHER ROUND OF

.PREV DISCUSSION... /ISSUED 1000 PM CDT WED APR 16 2008/

UPDATE...
CHALLENGE FOR TONIGHT WILL BE THUNDERSTORM POTENTIAL ACROSS THE
AREA.

LATEST SURFACE ANALYSIS INDICATES QUASI-STATIONARY FRONTAL
BOUNDARY STRETCHING FROM THE EASTERN OKLAHOMA
PANHANDLE...NORTHEAST TO NEAR HUTCHINSON AND INTO NORTHEAST
KANSAS. STRENGTHENING LOW-LEVEL JET HAS LEAD TO EXTENSIVE ACCAS
OVER THE PAST FEW HOURS ALONG/NORTH OF THE FRONT...ALSO IN
RESPONSE TO LIFT UNDERNEATH RIGHT ENTRANCE REGION OF UPPER JET. AS
LOW-LEVEL JET INCREASES FURTHER ALONG WITH ASSOCIATED ISENTROPIC
ASCENT AND MOISTURE TRANSPORT...THINKING THUNDERSTORM ACTIVITY
WILL BREAK OUT OVER THE NEXT FEW HOURS ACROSS SOUTH-
CENTRAL/CENTRAL KANSAS...ESPECIALLY FOCUSED ALONG/NORTH OF THE
FRONT...AND WEST OF I-135. ADDITIONALLY...AN APPROACHING SUBTLE
SHORTWAVE OVER THE TEXAS PANHANDLE MAY ALSO AID DEVELOPMENT. STEEP
MID-LEVEL LAPSE RATES PER 00Z SOUNDINGS ATOP INCREASING LOW-LEVEL
MOISTURE WILL AID INSTABILITY. ADDITIONALLY...THE HAVILAND
PROFILER INDICATES AMPLE CLOUD BEARING SHEAR. SO ALL IN
ALL...ANTICIPATING STORMS WILL BE STRONG/MARGINALLY SEVERE...BUT
DO NOT THINK WELL GET WIDESPREAD SEVERE DUE TO LIKELY SOMEWHAT
LIMITED INSTABILITY. THREAT WILL BE DIME-QUARTER SIZE HAIL AND
LOCALLY HEAVY RAIN. ACTIVITY WILL THEN MOVE NORTHEAST. FOR THE
MOST PART...AM NOT ANTICIPATING WIDESPREAD ACTIVITY ACROSS
SOUTHEAST KANSAS DUE TO LACK OF FOCUS FOR THUNDERSTORM INITIATION.

NEXT 24 HOURS. QUASI-STATIONARY FRONTAL BOUNDARY OVER THE AREA
WILL RETREAT BACK NORTHWEST THIS EVENING...AS LARGE TROUGH
APPROACHES FROM THE WEST. ANTICIPATING SHOWERS/THUNDERSTORMS TO
INCREASE IN AREAL COVERAGE ACROSS SOUTH-CENTRAL/CENTRAL KANSAS BY
LATE THIS EVENING...AS LOW-LEVEL JET INCREASES AND ACTS UPON
BOUNDARY IN PLACE. COVERAGE SHOULD GET FAIRLY NUMEROUS ROUGHLY
ALONG AND NORTHWEST OF THE KANSAS TURNPIKE. WILL LIKELY NEED TO
EVENTUALLY INSERT TEMPO/PREVAILING GROUPS FOR -TSRA. ANTICIPATING
SOME ACTIVITY GETTING INTO SOUTHEAST KANSAS AS WELL...BUT NOT AS
WIDESPREAD. ADDITIONALLY...CIGS WILL GRADUALLY LOWER...AS MOISTURE
INCREASES AND DIURNAL COOLING COMMENCES. THINKING A GOOD CHUNK OF
THE AREA WILL GET DRY-SLOTTED TOMORROW...WHICH SHOULD ACT TO SHUT
DOWN THE MAJORITY OF SHOWER/THUNDERSTORM ACTIVITY. BUT LOW CLOUDS
AND DRIZZLE WILL PREVAIL. ANTICIPATE LOCATIONS NORTH OF THE FRONT
WILL HAVE IFR OR LOWER CIGS. BY AFTERNOON/EVENING...ANOTHER ROUND
OF SHOWERS/THUNDERSTORMS SHOULD ROLE ACROSS MAINLY SOUTHEAST

DISCUSSION...

SYNOPSIS:
MID-UPR TROF CONTINUES TO DIG OVER SRN ROCKIES THIS AFTERNOON WITH COLD
FRONT SAGGING S/SE TOWARD SC KS. SLIGHTLY HIGHER SFC DEWPOINTS IN LWR TO
MID 50S CONTINUE TO MIGRATE N INTO SC & SE KS & WITH COLD FRONT
ENCROACHING UPON SC KS TSRA TO DEVELOP FIRST OVER WRN 1/3 OF CWFA THIS
EVENING WHERE SFC-850MB CONVERGENCE STRONGEST. WITH MID-UPR TROF DIGGING
OVER NM TONIGHT THE FRONT WILL STALL...SETTING UP CAMP IN AN ALMOST S-N
MANNER VERY CLOSE TO I-135. AS RESULT...BEST CHANCES FOR SHRA/TSRA WILL
TARGET C & SC KS TONIGHT WITH CONVECTION SPREADING E ACROSS SE KS EARLY
THU MORNING.

TONIGHT-THU NIGHT:
PER SYNOPSIS HAVE RE-ORIENTED HIGHEST POPS (CATEGORICAL) FOR TONIGHT
OVER NW 1/3 OF CWFA WHERE 925-850MB CONVERGENCE STRONGEST WITH LOWEST
POPS (40-50%) ASSIGNED TO SE KS. WITH LIMITED INSTABILITY CONFINED TO
SW CORNER OF CWFA...+RA TO BE PRIMARY THREAT FROM TSRA THAT DEVELOP...
ESPECIALLY OVER C & SC KS WHERE BETTER ALIGNED WITH 925-850MB
BAROCLINIC AXIS. WITH THE AFORE-MENTIONED UPR TROF CONTINUING TO DIG
OVER NM...THE FRONTAL BOUNDARY WILL PIVOT IN COUNTER-CLOCKWISE MANNER.
AS SUCH TSRA WILL SPREAD ACROSS SC KS LATER TONIGHT & THU MORNING & OVER
SE KS DURING THE DAY THU. NO PLANS TO ISSUE FLOOD/FLASH FLOOD WATCHES AT
THIS TIME...BUT THIS FACET OF FORECAST WILL REQUIRE FURTHER ATTENTION AS
EVENT EVOLVES.

THIS WEEKEND:
THE UPR TROF DIGGING OVER NM TONIGHT & THU WILL PUSH E OVER SRN PLAINS
THU NIGHT & FRI...THEREBY PUSHING COLD FRONT IN LIKE MANNER ACROSS SRN &
CENTRAL PLAINS. AS SUCH STILL EXPECT RAIN TO END OVER SC KS EARLY FRI
MORNING & SE KS FRI AFTERNOON.

NEXT WEEK:
PRIMARY FORECAST FOCUS WILL BE ON BEHAVIOR OF COLD FRONT THATLL VENTURE
SE ACROSS C KS MON MORNING & SE KS MON AFTERNOON. WITH FAIRLY POTENT 500
MB SHORTWAVE PROGGED TO SCOOT NE ACROSS WY & WRN DAKOTAS MON MORNING THE
FRONT WILL DECELERATE AS IT CROSSES SE KS...POSSIBLY STALLING OVER SE KS
MON NIGHT. WITH THE QUASI-STATIONARY FRONT LURKING ABOUT THE CHANCES FOR
TSRA ARE STARTING TO INCREASE FROM MON-TUE (ESPECIALLY ACROSS SC & SE KS
WHERE CLOSER TO THE FRONT THATLL GRADUALLY ASSUME MORE W-E ORIENTATION.
A 2ND & EQUALLY POTENT 500-MB SHORTWAVE IS PROGGED TO SPRINT NE FROM CO
& WY ACROSS NEBRASKA/SD TUE WHICH...POSSESSING A MORE SLY TRACK...SHOULD
KICK THE COLD FRONT SE WITH THE FRONT SUBTLY CURVING NE FROM W TX ACROSS
SRN OK TO SRN MO TUE EVENING. THE FRONTS BEHAVIOR WILL HAVE SIGNIFICANT
RAMIFICATIONS ON BOTH TEMPS & POPS MON-TUE. AS SUCH HAVE BEGUN TO PRESS
HARDER ON POP THROTTLE ACROSS THE AREA...ESPECIALLY SC & SE KS.
