AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
652 PM CDT WED JUL 15 2015

...UPDATE TO AVIATION FORECAST DISCUSSION...

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 254 PM CDT WED JUL 15 2015

COMPLICATED FORECAST CONTINUES WITH MULTIPLE FEATURES ALOFT AND AT
THE SURFACE IN A POTENTIALLY VERY VOLATILE ATMOSPHERE. PRECIPITATION
HAS SLOWLY WANED ON THE BACK EDGE OF THE MORNING MESOSCALE
CONVECTIVE SYSTEM IN MID LEVEL WARM AIR ADVECTION WITH SOME SIGNAL
OF THE OLD OUTFLOW NEAR CNU. WINDS ON BOTH SIDES OF THE OUTFLOW
VEERING WITH A LACK OF STRONG CONVERGENCE RESULTING. UPPER WAVE WITH
THE OVERNIGHT SYSTEM WAS INTO WESTERN IOWA BUT THERE ARE INDICATIONS
OF A LEAST ONE WEAK WAVE IN THE TROPICAL PLUME OVER EASTERN
COLORADO, AND CONVECTION IS BECOMING MORE ROBUST THERE. THE OUTFLOW
AND RESIDUAL PRECIP IS HELPING KEEP FEELS-LIKE TEMPS MORE BEARABLE
TODAY WITH VALUES ABOVE 100 THE EXCEPTION.

MAIN SHORT-TERM CONCERN REMAINS TO BE SEVERE WEATHER POTENTIAL.
EASTERLY LOW LEVEL WIND COMPONENT UNDER SEASONALLY STRONG MID/UPPER
WESTERLIES LEADING TO DEEP-LAYER SHEAR EASILY SUPPORTING OF
SUPERCELLS...WITH MLCAPE GENERALLY IN THE 2000-4000 J/KG RANGE. WITH
THE AREA BETWEEN BETTER FORCING MECHANISMS ALOFT, SURFACE
CONVERGENCE WOULD SEEM TO BE THE PRIMARY NEED FOR STORMS AND IS NOT
VERY STRONG AT THIS POINT. WILL CONTINUE WITH SMALL POPS MOST
LOCATIONS INTO THE EVENING IN CASE AN AREA OF CONSTANT FOCUS
MATERIALIZES. BEYOND THE SHORTER TERM, WILL BE WATCHING ORGANIZATION
OF STORMS TO THE WEST WITH VARIOUS IDEAS OF HOW THIS WILL TRANSPIRE
TONIGHT. LOW LEVEL JET OF 30-40KT SHOULD SUPPORT CONVECTION INTO
EASTERN KANSAS, WITH ELEVATED CAPE DECREASING FROM SOUTH TO NORTH
THROUGH THE NIGHT KEEPING BETTER CHANCES IN THE NORTH. PRECIPITABLE
WATER VALUES AROUND 1.8 INCHES ARE WELL ABOVE NORMAL THOUGH A
GENERALLY PROGRESSIVE MCS SEEMS MORE LIKELY KEEPING A HIGH HEAVY RAIN
CONCERN IN CHECK.

FOR THURSDAY, MCS ACTIVITY SHOULD BE ENDING QUICKER THAN TODAY WITH
A WEAKER UPPER SUPPORT ANTICIPATED. A WEAK SURFACE TROUGH IS
SUGGESTED TO BE DRAPED ACROSS THE AREA IN THE AFTERNOON THOUGH MID
LEVEL WARM AIR ADVECTION SHOULD PUT MORE OF A CAP IN PLACE. WILL
ONLY GO WITH SMALL CHANCES NEAREST THE TROUGH AT THIS POINT. HAVE
REMAINED SOMEWHAT CONSERVATIVE WITH HIGH TEMPS GIVEN STILL SOME
UNCERTAINTY ON CLOUD/PRECIP TRENDS AND MIXING DEPTHS. DEWPOINTS
AGAIN INTO THE MID 70S WILL BRING POTENTIAL FOR HEAT INDEX VALUES
AROUND 105 AND AN ADVISORY FOR MUCH OF THE AREA MAY BE NEEDED IF
CONFIDENCE INCREASES.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 254 PM CDT WED JUL 15 2015

FOR THE PERIOD THURSDAY NIGHT THROUGH SATURDAY...KANSAS REMAINS ON
THE NORTH EDGE OF THE SUBTROPICAL HIGH THROUGH THIS PERIOD WITH
SOUTHWEST FLOW ALOFT. WATER VAPOR IMAGERY TODAY SHOWED A MOISTURE
PLUME STREAMING NORTH ON THE WEST SIDE OF THE HIGH INTO THE
CENTRAL PLAINS. THE MOISTURE PLUME WILL REMAIN OVER EASTERN KANSAS
DURING THE FRIDAY AND SATURDAY TIME PERIOD. AT THE SURFACE, THERE
SHOULD BE A WEAK TROUGH IN THE VICINITY WITH GENERALLY SOUTHERLY
FLOW. MOISTURE SHOULD BE PLENTIFUL AND THE ATMOSPHERE SHOULD
REMAIN UNSTABLE. HOWEVER, THE LACK OF ANY SIGNIFICANT FORCING AND
WARM MID LEVEL TEMPERATURES MAKE TIMING PRECIPITATION CHANCES
DIFFICULT IN BOTH TIME AND SPACE. ALL THE MODELS GENERATE SPOTTY
PRECIPITION IN THE MOISTURE PLUME AND WILL CARRY SMALL POPS MOST
PERIODS.

TEMPERATURES COUPLED WITH THE HIGH DEW POINTS SHOULD RESULT IN
HIGH APPARENT TEMPERATURES THROUGH THIS PERIOD. THE THERMAL RIDGE
LOOKS MOST PRONOUNCED ON SATURDAY WITH 850 TEMPERATURES PUSHING
THE UPPER 20S C WHICH SUPPORTS HIGHS NEAR 100 IN THE WESTERN
COUNTIES. WITH ALL OF THE RECENT RAINFALL, IT WILL BE HARD TO
LOWER DEW POINTS DUE TO MIXING WHICH HAS BEEN THE CASE RECENTLY.
GIVEN THIS, EXPECT APPARENT TEMPERATURES TO REACH AROUND 105 F
EACH AFTERNOON FRIDAY AND SATURDAY WITH SATURDAY A LITTLE HIGHER.
WILL HIGHLIGHT THE PROLONGED HEAT IN OUR SOCIAL MEDIA VIA THE WEATHER
STORY AND THE HWO FOR NOW. HEADLINES MAY BE NEEDED AT SOME POINT
AS TIME PERIOD APPROACHES.

IN THE EXTENDED...SUNDAY LATE AFTERNOON INTO THE OVERNIGHT HOURS
WILL BE THE MOST ACTIVE PERIOD LOOKING AHEAD. THERE REMAINS GOOD
CONSISTENCY WITH A COOL BOUNDARY BEING FORCED INTO THE CENTRAL
PLAINS AND MAKING ITS WAY JUST THROUGH THE OUTLOOK AREA INTO
PORTIONS OF SOUTHERN KS BEFORE STALLING OUT GENERALLY AND LIKELY
LINGERING THEREAFTER. THE BEST FORCING FOR SEVERE LOOKS TO BE OVER
THE EASTERN HALF OF THE OUTLOOK AREA WITH SHEAR PARAMETERS,
MUCAPES AND LOW LEVEL HELICITY VALUES SUPPORTIVE OF STRONG TO
SEVERE STORMS SHOULD EVERYTHING PLAY OUT AS CURRENTLY PROGGED. THE
GFS IS DEVELOPING SURFACE FEATURES DEEPER THAN THE ECMWF BUT
PLACEMENT AND TIMING IS AGAIN GENERALLY SIMILAR. THE NEXT
SHORTWAVE THAT COULD DEVELOP A STORM SYSTEM SHOULD HOLD OFF UNTIL
WEDNESDAY NIGHT TIME FRAME.

RELATIVELY COOLER TEMPS ARE INTRODUCED FOR MONDAY BEHIND THE FRONTAL
SYSTEM AND RAIN COOLED AIR.  BUT THEY DON'T LAST TOO LONG AS TEMPS
AGAIN RISE INTO THE 90S BY TUESDAY AND WEDNESDAY.  LOWS WILL MOSTLY
RANGE IN THE 70S.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 644 PM CDT WED JUL 15 2015

SEVERAL BOUNDARIES REMAIN IN PLAY OVER THE NEXT 6 HOURS IN A LINE
THROUGH AND JUST NORTH OF THE TERMINALS. IT DOES APPEAR THAT
MAINLY VCTS CAN BE EXPECTED DUE TO THE NATURE OF THESE BOUNDARIES
AS IT WILL BE HARD TO PINPOINT ANY ONE PARTICULAR AREA OF STORMS.
OUTSIDE OF THIS EXPECT WINDS TO VEER BACK TO THE SOUTH ONCE AGAIN
INTO THE DAY TOMORROW. THERE MAY BE POTENTIAL FOR SOME STORMS
AFFECTING THE TERMINALS TOMORROW AFTERNOON BUT HAVE LEFT THAT FOR
A LATER FORECAST AS THE CHANCES LOOK TOO SMALL TO MENTION IN THE
TAFS.
