AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
408 AM CDT TUE JUL 14 2015

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 321 AM CDT TUE JUL 14 2015

EARLY TUESDAY MORNING, A LOOSELY ORGANIZED COMPLEX OF THUNDERSTORMS
WAS BUILDING INTO CENTRAL KANSAS WITH A STEADY EASTWARD PROGRESSION
ALONG AND JUST NORTH OF THE WEAK SURFACE FRONT...ANALYZED AT 3 AM
FROM HUTCHINSON THROUGH EMPORIA. THIS CONVECTION APPEARS TO BE
SOMEWHAT DRIVEN BY A SHORT WAVE TROUGH ENTERING SOUTHWEST KANSAS...
HELPING ENHANCE THE WEAK CONVERGENCE ALREADY PRESENT ALONG THE FRONT
IN SURFACE OBS AND 925 WIND PROFILES. THE ENVIRONMENT ALONG THE
FRONT IS RICH WITH INSTABILITY ALTHOUGH ELEVATED PARCELS APPEAR TO
BE AT LEAST WEAKLY CAPPED SO SOME PERSISTENT LIFT IS NEEDED AND THIS
MAY HELP EXPLAIN THE SOMEWHAT PULSE NATURE OF THE STRONGER STORMS IN
CENTRAL KS. THERE IS ALSO AROUND 30 KTS OF EFFECTIVE SHEAR WITH
POCKETS OF HIGHER VALUES WHICH COULD HELP ENHANCE A FEW UPDRAFTS
THIS MORNING. EXPECT THIS EASTWARD DEVELOPMENT TO CONTINUE THROUGH
SUNRISE ALTHOUGH IT WILL BE GETTING FARTHER FROM THE SHORT WAVE
FORCING AND EXPECT THE WEAK LLJ TO CONTINUE TO VEER WITH TIME AND
LIKELY RESULTING IN WEAKER CONVERGENCE. THE BEST STORM CHANCES
APPEAR TO BE SOUTH OF AN ABILENE TO OTTAWA LINE THROUGH MID MORNING.

THERE ARE AT LEAST SOME INDICATORS POINTING TOWARD CONTINUED
THUNDERSTORMS IN EAST CENTRAL KANSAS THROUGH MID DAY AS THIS SYSTEM
DRIFTS EAST WITH TIME. HOWEVER...IT SEEMS THAT THE FORCING SHOULD
WANE BY LATE MORNING WITH PRECIP COVERAGE DECREASING AS WELL AND
HAVE DECREASED PRECIP CHANCES IN EAST CENTRAL KANSAS BEYOND NOON
ALTHOUGH IT IS NOTEWORTHY THAT THERE IS A SLIGHT CHANCE FOR
CONVECTIVE REGENERATION INTO THE AFTERNOON. ASSUMING STORMS AND
CLOUDS DECREASE BY LATE MORNING...TEMPERATURES ARE STILL LIKELY TO
RISE INTO THE LOWER TO MIDDLE 90S ACROSS THE FORECAST AREA WITH VERY
HIGH DEWPOINTS IN THE MIDDLE 70S LIKELY NEAR AND SOUTH OF I-70 AND
ESPECIALLY ALONG THE I-35 CORRIDOR. THIS WILL LEAD TO HEAT INDEX
MAXING OUT IN THE 103 TO 109 RANGE BASICALLY ANYWHERE SOUTH OF AN
ABILENE TO MANHATTAN TO HOLTON LINE AND HAVE EXPANDED THE HEAT
ADVISORY SLIGHTLY NORTH ACCORDINGLY.

BY LATE AFTERNOON AND THROUGH TONIGHT, A STRONGER SHORT WAVE TROUGH
WILL MOVE INTO CENTRAL KANSAS WITH THUNDERSTORMS LIKELY TO DEVELOP
WEST OF THE FORECAST AREA AND BUILD EAST AND NORTHEAST WITH TIME.
THE SURFACE FRONTAL BOUNDARY WILL NOT MOVE MUCH TODAY AND MAY
PROVIDE AN ADDITIONAL FOCUS FOR THUNDERSTORM DEVELOPMENT
OVERNIGHT...OR PERHAPS A LOOSE FOCUS FOR MCS PROPAGATION.
INSTABILITY WILL AGAIN BE SUBSTANTIAL THROUGH TONIGHT WITH EFFECTIVE
SHEAR SUFFICIENT TO SUPPORT STORM ORGANIZATION. HAIL AND DAMAGING
WINDS WILL BE THE PRIMARY THREATS BUT AMPLE MOISTURE AND PWATS
GREATER THAN 2 INCHES SUGGEST FLASH FLOOD POTENTIAL AS WELL.

.LONG TERM...(WEDNESDAY THROUGH MONDAY)
ISSUED AT 321 AM CDT TUE JUL 14 2015

WEAK SHORTWAVE TROUGH IS PROGGED TO LIFT NORTHEAST OVER KANSAS AND
NEBRASKA ON WEDNESDAY AFTERNOON AND EVENING. SURFACE LOW OVER
WESTERN KANSAS WILL LIFT THE WARM FRONT NORTHWARD TOWARDS THE
NEBRASKA BORDER, WITH THE LATEST ECMWF BEING SLIGHTLY FURTHER SOUTH
WITH THE BOUNDARY DURING THE AFTERNOON. NEVERTHELESS, EXPECT MORNING
CONVECTION TO IMPACT PORTIONS OF NORTHERN KS WEDNESDAY MORNING,
LIFTING NORTHEAST THROUGH THE DAY. ANY RESIDUAL ACTIVITY COULD
INTENSIFY BY LATE AFTERNOON OR ADDITIONAL CONVECTION MAY FORM ALONG
THE BOUNDARY. FORECAST SOUNDINGS IN THIS AREA SHOW STEEPENING MID
LEVEL LAPSE RATES ALOFT WHILE EFFECTIVE SHEAR IS ENHANCED FROM THE
WAVE NEAR 40 KTS AT PEAK HEATING. ADEQUATE INSTABILITY IN THE AREA
WILL ALLOW FOR A FEW SEVERE STORMS WITH DAMAGING WIND GUSTS AND
LARGE HAIL. IF STORMS INTERACT NEAR THE FRONTAL BOUNDARY, AN
ISOLATED TORNADO IS POSSIBLE.

LIKELY PRECIP CHANCES WEDNESDAY EVENING QUICKLY DIMINISH TO SLIGHT
CHANCES FROM THURSDAY ONWARD AS HEIGHTS BUILD NORTHWARD INTO THE
AREA WITH NO PARTICULARLY STRONG SHORTWAVE TROUGH TO IMPOSE ON THE
RIDGING IN PLACE. PERIODIC SLIGHT CHANCES FOR STORMS WILL REMAIN
POSSIBLE WITH WEAK WAVES OF ENERGY RIDING ALONG THE NORTHERN
PERIPHERY OF THE RIDGE THURSDAY AND FRIDAY EVENINGS. FROM SUNDAY
ONWARD, FORECAST CONFIDENCE DECREASES AS A STRONGER SOUTHWEST TROUGH
DEEPENS OVER THE WESTERN CONUS. THE ECMWF CURRENTLY TRENDS FASTER
WITH THE WAVE PROGRESSING OVER THE NORTHERN PLAINS ON SUNDAY,
FORCING A COLD FRONT AND MORE WIDESPREAD PRECIP CHANCES SUNDAY
EVENING AND MONDAY. THE GFS AND CANADIAN SOLUTIONS ARE ABOUT 24
HOURS SLOWER WITH THIS BOUNDARY ARRIVING ON MONDAY, WHILE THE
SUBSEQUENT UPPER TROUGH IS WEAKER WITH LESSER FORCING FOR
CONVECTION. BASED ON THESE UNCERTAINTIES, LOWERED CHANCES TO SLIGHT
THROUGH TUESDAY.

IN TERMS OF TEMPERATURES, ONLY EXPECTING A SLIGHT IMPROVEMENT IN
HEAT INDICES WEDNESDAY AND THURSDAY WITH THE CLOUD COVER AND
POSSIBLE PRECIP IN THE AREA LOWERING MAX APPARENT TEMPS FROM 94 TO
103 DEGREES. THEREAFTER, HEAT INDICES QUICKLY RISE INTO THE LOWER
100S THROUGH MONDAY WHILE OVERNIGHT LOWS HOVER IN THE LOWER AND
MIDDLE 70S.

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z TUESDAY NIGHT)
ISSUED AT 1214 AM CDT TUE JUL 14 2015

EXPECT VFR CONDITONS THROUGH THE NEXT 24 HOURS. THERE IS A CHANCE
FOR ISOLATED STORMS TONIGHT AND AGAIN TUESDAY EVENING NEAR THE
TERMINALS BUT THE CHANCES AT THIS TIME LOOK TOO LOW TO INCLUDE A
MENTION IN THE TAFS.
