AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
1136 PM CDT THU JUN 14 2012

.AVIATION...06Z TAFS KRSL/KSLN/KHUT/KICT/KCNU

QUASI-LINEAR CONVECTIVE SYSTEM WILL CONTINUE MOVING SOUTHEAST
ACROSS SOUTH CENTRAL AND SOUTHEAST KANSAS OVERNIGHT. A TRAILING
STRATIFORM RAIN SHIELD WITH OCCASIONAL LIGHTNING STRIKES WILL
CONTINUE BEHIND THE LINE OF STORMS. MAIN THREAT WITH THE LINE WILL
BE WIND GUSTS TO 35 KT AND HEAVY RAIN REDUCING VISIBILITIES TO IFR.
WILL UTILIZE TEMPO OR PREVAILING TS AT HUT/ICT/CNU/SLN IN THE
SHORT TERM. WINDS SHOULD RESUME SOUTHEASTERLY WITH SOME GUSTS
DURING FRIDAY. ADDITIONAL CONVECTION COULD FORM OVER THE HIGH
PLAINS IN THE PM/EVE BEFORE MOVING EAST OVERNIGHT. CONFIDENCE ON
TIMING IS LOW REGARDING THIS CONVECTION REACHING OUR TAF SITES SO
WILL LEAVE TS OUT FOR NOW.

.PREV DISCUSSION... /ISSUED 942 PM CDT THU JUN 14 2012/

UPDATE...

MATURE QUASI-LINEAR CONVECTIVE SYSTEM NOW IN PROGRESS FROM
SOUTHWEST THROUGH CENTRAL AND NORTHEAST KS...WITH CLOUD TOPS OF
-70 TO -77 CELSIUS. THE MCS WILL LIKELY CONTINUE TRACKING
SOUTHEAST OVERNIGHT INTO THE 40 KNOT SOUTHERLY LOW-LEVEL JET. THE
LOW-LEVEL JET WILL RESULT IN STRONG MOISTURE TRANSPORT NORTHWARD
INTO THE STORM COMPLEX WHICH SHOULD SUSTAIN IT FOR MUCH OF THE
NIGHT. LACK OF SHEAR MAY KEEP A LOT OF THE ACTIVITY SUB-
SEVERE...HOWEVER WE SHOULD STILL BE ABLE TO GET SOME 60 MPH GUSTS
ALONG THE LEADING EDGE OF STRONGER GUST FRONT SURGES. TORRENTIAL
RAIN ALREADY BEING OBSERVED IN THE MOST INTENSE CORES IN CENTRAL
KS AND WITH PRECIPITABLE WATER OF 1.5 TO 1.75 INCHES...THIS TREND
SHOULD CONTINUE FOR SEVERAL MORE HOURS. HAVE BOOSTED RAIN CHANCES
CONSIDERABLY OVERNIGHT GIVEN RECENT RADAR AND SHORT RANGE MODEL TRENDS.

PREV DISCUSSION... /ISSUED 631 PM CDT THU JUN 14 2012/

AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU

MAIN CONCERN IS STRONG THUNDERSTORMS TONIGHT.

THUNDERSTORMS WILL CONTINUE TO CONGEAL ACROSS WESTERN THRU NORTH
CENTRAL KS THIS EVENING...AS LOW-LEVEL SOUTHERLY FLOW CONVERGES
INTO A STALLED FRONTAL BOUNDARY. A FULL-FLEDGED MCS SHOULD BE IN
PROGESS BY 01-02Z...AND THIS SHOULD PROPAGATE SOUTHEASTWARD INTO
CENTRAL AND SOUTH CENTRAL KS THIS EVENING. HAVE UTILIZED TEMPO TS
GROUPS AT RSL-SLN-HUT-ICT WITH SOME GUSTY WINDS AND HEAVY RAIN LIKELY
ASSOCIATED WITH THE STORMS. NOT SURE IF THE MCS WILL SURVIVE AS
FAR SOUTHEAST AS CNU BUT HAVE INSERTED A VCTS THERE LATE TONIGHT.
SOME MID-HIGH CLOUDS COULD LINGER FRIDAY MORNING IN WAKE OF MCS.

PREV DISCUSSION... /ISSUED 332 PM CDT THU JUN 14 2012/

DISCUSSION...

TONIGHT:
TOUGH FORECAST WITH MODEL OUTPUT HIGHLY VARIABLE DUE TO DIFFERING
MODEL CONVECTION TIMING/LOCATION. 1200 UTC NAM LOW LEVEL MOISTURE
FIELDS ARE SUSPECT OUT OF THE BOX BASED ON OBSERVED DATA AND HAVE
DOUBTS ABOUT EARLY INITIATION IT SUGGESTS. THE 1200 UTC GFS WAS NOT
MUCH BETTER AS FRONT DID NOT LIT UP BY 1800 UTC. EVEN 0000 UTC
ECMWF WAS OVERLY AGGRESSIVE. BASED ON 1200 UTC RAOBS...DECENT
PLUME OF 850MB MOISTURE IS LOCATED OVER SOUTHWEST/WEST CENTRAL OK
WITH MOISTURE STARTING TO POOL ALONG 850MB FRONT. DRIER AIR WAS
LOCATED OVER EASTERN KS/NE OK. EXTREMELY WEAK SHORTWAVE EVIDENT
IN WATER VAPOR/ACAR WINDS THIS MORNING OVER WESTERN COLORADO. AT
1800 UTC SURFACE FRONT HAD JUST PUSHED INTO THE NORTHWEST TIP OF
KS. DO ANTICIPATE STORMS TO DEVELOP ALONG FRONT LATE AFTERNOON...AND
PERSIST OVERNIGHT. GIVEN WEAK WAVE AND BETTER MOISTURE TO THE
WEST...THINKING BEST CHANCES WILL BE IN CENTRAL KS WITH MCS
PERSISTING OVERNIGHT ALONG LEADING THETA-E GRADIENT. NOT AT ALL
CLEAR HOW FAR SOUTH STORMS WILL DEVELOP OVERNIGHT GIVEN WEAK
FORCING...OUTFLOW DOMINATED STORMS AND WEAK FLOW ALOFT. COULD SEE
ISOLATED HEAVY RAIN POTENTIAL ACROSS CENTRAL KS GIVEN EFFICIENT
RAIN PRODUCING STORMS AND PRECIPITATION DURATION. GIVEN LARGE
CAPE AND DEEP DRY ADIABATIC LAPSE RATES WITH COPIOUS DRY AIR
ALOFT...MAIN THREAT WILL BE DAMAGING WINDS...ALTHOUGH LARGE HAIL
WITH INITIAL STORM DEVELOPMENT CANNOT BE RULED OUT. ALSO CANNOT
RULE OUT AN ISOLATED LANDSPOUT WITH A FAVORABLE OUTFLOW BOUNDARY
INTERSECTION...GIVEN LOW LEVEL WIND PROFILE AND STEEP LAPSE RATES
NEAR SURFACE.

FRI-SUN:
FRI COULD HAVE CONVECTIVE DEBRIS LINGERING DURING THE MORNING...MOST
LIKELY IN EASTERN SECTIONS. WHILE STORMS ARE NOT LIKELY IN
SUBSIDENCE IN WAKE OF MCS...LINGERING BOUNDARY COULD BE ENOUGH FOR
NEW DEVELOPMENT...ESPECIALLY IN WESTERN SECTIONS. HOWEVER UNCLEAR
WHERE THAT BOUNDARY WILL BE. NO CONFIDENCE IN MODEL SOLUTIONS
GIVEN UNCERTAINTY IN THE NEAR TERM. BEST BET WOULD BE CENTRAL KS
FRI NIGHT AS SURFACE BOUNDARY DRIFTS CLOSER...ESPECIALLY WHERE IT
INTESECTS MCS OUTFLOW BOUNDARY. AGAIN SOUTHERN EXTENT IS
PROBLEMATIC. ON SAT...CHANCES ARE MORE LIKELY ACROSS CENTRAL KS
ONCE AGAIN IN THE VICINITY OF FRONT...ESPECIALLY SAT NIGHT.
UNCLEAR HOW FAR SOUTH BOUNDARY WILL GO ON SUN AND OPTED TO KEEP
MOST OF THE AREA DRY FOR NOW.

MON-THU:
STILL CONSIDERABLE UNCERTAINTY THIS PERIOD AS MODELS STUGGLE
BADLY WITH LOCATION/TIMING OF SURFACE FRONT. BOTH ECMWF/GFS HAVE
BEEN QUITE ERRATIC OVER THE PAST FEW RUNS...WITH VERY LOW
CONFIDENCE IN ARRIVAL OF NEXT SIGNIFICANT COLD FRONT MIDWEEK.
TEMPERATURES SHOULD REMAIN AT OR ABOVE NORMAL THROUGH MOST OF THIS
PERIOD. AM NOT VERY CONFIDENT ON PRECIPITATION ARRIVING WED
NIGHT...AND IT COULD BE A STRETCH EVEN ON THU DURING THE DAY. BEST
GUESS AT THIS POINT WOULD BE THU NIGHT. -HOWERTON
