AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
648 PM CDT FRI JUL 31 2009

.UPDATE...

TWEAKED GRIDS A BIT EARLIER TO ACCOUNT FOR CURRENT TRENDS AND FINE
TUNE PRECIPITATION TIMING OVERNIGHT. LOOKS LIKE BULK OF
PRECIPITATION WILL NOT ARRIVE UNTIL AFTER MIDNIGHT...AND CLOSER TO
DAYBREAK IN SE KS. LOOKS LIKE SEVERE THREAT WILL BE CONTINGENT ON
GETTING ORGANIZED COLD POOL GOING...OTHERWISE CONVECTIVE AVAILABLE
POTENTIAL ENERGY AROUND 1000 J/KG AND 30 KTS OR LESS 0-6KM SHEAR
DOES NOT BODE WELL FOR SIGNIFICANT SEVERE OTHERWISE. WINDS SHOULD
REMAIN GUSTY INTO THE EVENING WITH RELATIVELY TIGHT SURFACE
PRESSURE GRADIENT AHEAD OF FRONT. -HOWERTON

&&

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

THUNDERSTORMS JUST AHEAD/ALONG COLD FRONT WILL AFFECT ALL SITE
THIS PERIOD. STORMS SHOULD MOVE INTO KRSL AROUND 06-07 UTC AND
KCNU JUST AFTER DAYBREAK. APPEARS THAT MARGINAL VISUAL FLIGHT
RULES CEILINGS WILL BE LIKELY BOTH IN AND JUST BEHIND
STORMS...WITH CONDITION THEN IMPROVING RELATIVELY QUICKLY BEHIND
FRONT AS DRIER AIR MOVE IN. -HOWERTON

.PREV DISCUSSION... /ISSUED 324 PM CDT FRI JUL 31 2009/

DISCUSSION...
FORECAST CHALLENGES ARE CHANCES OF THUNDERSTORMS FOR TONIGHT AND
INTO SATURDAY THEN WARMING TREND FOR NEXT WEEK.

TONIGHT:
LOWERED POPS IN SOUTH CENTRAL KANSAS FOR TONIGHT AS THE FRONT SEEMS
TO BE REACHING CENTRAL KS AROUND MIDNIGHT. AS THE FRONT PROGRESSES
EASTWARD EXPECT THE BULLSEYE OF PRECIP TO BE IN CENTRAL KANSAS WHERE
THE BEST ISENTROPIC LIFT AND INSTABILITY REMAINS. DUE TO LACK OF
SHEAR NOT EXPECTING A WIDESPREAD SEVERE EVENT...PULSE STORMS AND
HEAVY DOWNPOURS ARE THE MAIN CONCERN AS SOME STORMS MAY BE STRONG TO
SEVERE. MADE MINOR ADJUSTMENTS TO TEMPS AND DEWPOINTS TO ACCOUNT FOR
CURRENT TRENDS.

SATURDAY:
SURFACE FRONT SHOULD BE NEAR A MARION TO HUTCHINSON BY SATURDAY
MORNING WITH SCATTERED THUNDERSTORMS EXPECTED ALONG AND AHEAD OF THE
FRONT. THE FRONT WILL CONTINUE MOVING TO THE SOUTHEAST AND BE NEAR A
LINE FROM IOLA TO ARKANSAS CITY BY NOON THEN OUT OF THE AREA BY LATE
AFTERNOON. PROGRESSED THE CHANCES OF THUNDERSTORMS EASTWARD WITH THE
FRONT...ANTICIPATING IT TO ALL BE OUT OF THE FORECAST AREA BY 5:00
PM. TEMPERATURES SHOULD ONE AGAIN BE BELOW NORMAL WITH HIGHS IN THE
85 TO 90 DEGREE RANGE.

SUNDAY THROUGH WEDNESDAY:
DONT ANTICIPATE A WHOLE LOT OF CHANGE IN THE OVERALL WEATHER
PATTERN AS WE MOVE INTO NEXT WEEK. UPPER LEVEL CLOSED LOW REMAINS
NEARLY STATIONARY ON THE PACIFIC COAST WITH A RIDGE OF HIGH PRESSURE
CONTINUING TO PLAGUE THE WESTERN U.S. ANOTHER CLOSED LOW IN THE
VICINITY OF HUDSON BAY WITH SHOTS OF ENERGY MOVING AROUND THAT
SYSTEM. TUESDAY NIGHT AND INTO WEDNESDAY A SHORT WAVE SHOULD MOVE
AROUND THE HUDSON BAY LOW WHICH WILL BRING A FRONTAL SYSTEM THROUGH
THE AREA. BELIEVE THAT THE MAIN ENERGY WITH THIS SYSTEM WILL REMAIN
TO OUR NORTHEAST...BUT CANT RULE OUT CONVECTION FOR OUR AREA
TUESDAY NIGHT...THEN THE SOUTHERN HALF OF THE FORECAST AREA ON
WEDNESDAY. SINCE THE MAIN ENERGY REMAINS TO OUR NORTHEAST WILL ONLY
GO SLIGHT CHANCES ON THE PRECIPITATION.  SOME OF THAT ENERGY COULD
WORK INTO FAR SOUTHEAST KANSAS TUESDAY NIGHT.

THURSDAY THROUGH FRIDAY:
MODELS ARE STARTING TO COME IN LINE WITH TAKING THE CLOSED LOW OFF
THE WEST COAST AND MOVING IT ONSHORE THE LATTER PART OF NEXT WEEK.
THIS WOULD TAKE THE UPPER LEVEL RIDGE AND MOVE IT EASTWARD. ALOT OF
UNCERTAINTY CONCERNING TIMING FOR THIS TO OCCUR SO AM HESITANT TO
BE TOO AGGRESSIVE IN WARMING TEMPERATURES UP...HOWEVER HAVE TAKEN
THEM TO SEASONAL AND SLIGHTLY ABOVE. LOOKS AS THOUGH THERE WILL BE A
SHOT OF ENERGY MOVING AROUND THE BROAD UPPER LEVEL TROF THAT REMAINS
OVER THE NORTHEAST U.S. THIS SHOULD MOVE A FRONTAL SYSTEM ACROSS THE
AREA THURSDAY NIGHT AND INTO FRIDAY. INSERTED SMALL PROBABILITIES OF
THUNDERSTORMS IN FAR SOUTHEAST KANSAS ON FRIDAY. COULD SEE OTHER
CHANCES OF THUNDERSTORMS...MAINLY NIGHT-TIME THROUGH THIS
PERIOD...BUT AGAIN CONFIDENCE VERY LOW SO WILL LEAVE DRY FOR NOW.

AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
LATEST VISIBLE IMAGERY WAS SHOWING THE MID LEVEL CLOUDS CONTINUING
TO SPREAD EAST ACROSS THE AREA...DUE TO DECENT ISENTROPIC LIFT
AROUND 310K. OTHERWISE...SOUTHERLY FLOW WILL PREVAIL THIS
AFTERNOON AND EVENING. AFTER MIDNIGHT...SCATTERED TO NUMEROUS
STRONG THUNDERSTORMS WILL DEVELOP OVER PORTIONS OF CENTRAL
KANSAS AHEAD OF A FRONTAL BOUNDARY. THIS CLUSTER OF STORMS SHOULD
GRADUALLY PROPAGATE SOUTHEAST INTO SOUTH CENTRAL AND SOUTHEAST
KANSAS BY DAYBREAK. TIMING WISE WE WENT AHEAD AND INTRODUCED THE
VCTS CHANCES AT RSL AROUND
06Z/SLN(07Z)/HUT(08Z)/ICT(10Z)/CNU(14Z). THESE STORMS SHOULD
GRADUALLY EXIT THE AREA AFTER DAYBREAK WITH PARTIAL CLEARING
EXPECTED AS THE MORNING WEARS. OVERALL...VFR CONDITIONS WILL
PREVAIL.
