.DISCUSSION...

TONIGHT:
MESOSCALE CONVECTIVELY INDUCED VORT OVER ERN KS AT MID PM, WL LIKELY
CONTINUE TO SPARK A FEW SHOWERS/T-STORMS OVER SERN KS THRU EARLY
EVE. OTHERWISE, LATEST SFC ANALYSIS INDICATED A SFC TROUGH FM
W-CNTRL KS THRU N-CNTRL KS, INTO ERN NEBRASKA. THIS BOUNDARY IS
BEING AIDED BY AN UPSTREAM SHORTWAVE TROF TRAILING FM THE NRN PLAINS
ACROSS WRN NEBRASKA INTO ERN CO THIS PM. AS THE SHORTWAVE MOVES INTO
KS THIS EVENING, SCATTERED THUNDERSTORMS SHOULD DEVELOP NR THE SFC
TROUGH IN CNTRL KS WITH THAT AREA NOW EXPERIENCING MODERATE
INSTABILITY WITH SOME DIRECTIONAL SHEAR. A FEW OF THOSE STORMS COULD
BE SVR WITH DOWNBURST WINDS AND HAIL THREAT. STORMS SHOULD MOVE AND
PROPAGATE SEWD INTO S-CNTRL KS AND THE FLINT HILLS THIS EVENING.
HIGHEST POPS TARGETED FOR S-CNTRL/SERN KS WITH THAT AREA IN BEST
ISENTROPIC LIFT AND WEAK 850 THETA-E ADVECTION. SVR THREAT SHOULD
DIMINISH TOWARD MIDNIGHT WITH LOSS OF DAYTIME HTG. SOME LOWER CLOUDS
SHOULD DEVELOP ALONG/E OF THE KS TURNPIKE LATE TONIGHT, WITH THOSE
CLOUDS LINGERING INTO SUN AM.

SUNDAY:
WL HANG ONTO SOME 20-30% POPS IN SERN KS FOR MAINLY THE MORNING HRS,
BUT CONVECTION SHOULD SHIFT SEWD OUT OF SERN KS IN THE AFTERNOON IN
THE WAKE OF THE DEPARTING UPR LVL TROF. THE SFC BOUNDARY SHOULD
GRADUALLY DISSIPATE IN THE AFTERNOON AS NEW LOW PRESSURE FORMS IN
WRN SD. HIGHS IN LOW-MID 80S APPEAR REASONABLE WITH GENERALLY LIGHT
SE WINDS.

MONDAY:
CYCLOGENESIS WL CONTINUE TO TAKE PLACE DOWN INTO NWRN NEBRASKA WITH
THE PRESSURE GRADIENT TIGHTENING OVER KS. GUSTY SOUTH WINDS
EXPECTED, AND WITH MID LVL TEMPS WARMING SIGNIFICANTLY, OUR FCST
AREA SHOULD REMAIN CAPPED. LOW LVL THICKNESSES SUGGEST HIGHS FM UPR
80S SERN KS, TO MID 90S BY RSL/GBD.

TUES-SAT:
NO CHANGES PLANNED TO THE FCST FOR THIS TIME FRAME. EARLY IN THE
PERIOD, OUR FCST AREA SHOULD BE MAINLY UNDER THE INFLUENCE OF THE
UPPER HIGH CENTERED FROM THE UPR MIDWEST/OH VLY INTO THE SERN U.S..
NEXT UPPER TROF OUT WEST IS PROGGED TO EJECT OUT ACROSS THE
NRN/CNTRL PLAINS LATE THURSDAY INTO FRIDAY, ALTHOUGH SOME LINGERING
UPPER TROFFING WL LINGER IN THE WRN/CNTRL U.S. INTO THE WEEKEND.
COLD FRONT/DRYLINE PROGGED TO COME THRU OUR FCST SOMETIME THURS
NIGHT INTO FRIDAY, WHICH WL BE WHEN OUR NEXT DECENT CHANCE FOR
THUNDERSTORMS AND PSBL SEVERE WEATHER WL BE. LATER SHIFTS MAY END UP
BOOSTING POPS SOME.
