.DISCUSSION...
FORECAST CONCERNS...
CONVECTIVE TRENDS/SEVERE WEATHER THIS EVENING...THEN HEAVY RAINFALL
POTENTIAL OVERNIGHT...

SURFACE HEATING ALONG FRONTAL BOUNDARY HAS RESULTED IN MODERATE
INSTABILITY THIS AFTERNOON ACROSS PORTIONS OF SOUTHEAST KANSAS AND
THE SOUTHERN FLINT HILLS. THIS IN COMBINATION WITH MODEST DEEP LAYER
SHEAR WILL RESULT IN SEVERE POTENTIAL FOR AREAS EAST OF THE TURNPIKE
THIS EVENING. OTHERWISE...MODELS (GFS/NAM) SENDING FAIRLY DECENT
SIGNAL FOR ADDITIONAL ELEVATED CONVECTION LATER TONIGHT WITH AREA
OF ISENTROPIC LIFT DEVELOPING/TRANSLATING NORTHEAST ACROSS PORTIONS
OF SOUTH CENTRAL/SOUTHEAST KANSAS. WEAK TO MODEST ELEVATED CAPE AND
RELATIVELY HIGH PRECIPITABLE WATER (PWAT) VALUES AROUND 2 INCHES WILL
RESIDE ACROSS THIS SAME AREA, AND RESULT IN LOCALLY HEAVY RAINFALL
POTENTIAL. HPC AREAL QPF BULLSEYE LOOKS REASONABLE...THOUGH NOT AS
CONFIDENT ON MAX RAINFALL POTENTIAL. RAINFALL MAY APPROACH FFG
VALUES THOUGH COLLABORATION WITH ADJACENT OFFICES SUGGEST HOLDING
OFF ON ANY FLOOD WATCH HEADLINE FOR NOW. WILL KEEP HEAVY RAINFALL
MENTION IN GRIDS/ZONES AND HAZARDOUS WEATHER OUTLOOK TONIGHT.

AFTER TONIGHT...THE MODELS DIVERGE ON DETAILS SOMEWHAT (DUE TO
CONVECTIVE FEEDBACK ISSUES IN THE GFS)...THOUGH AGREE THAT THE
UNSETTLED WEATHER PATTERN WILL CONTINUE THROUGH MONDAY UNTIL
PASSAGE OF UPPER TROF...CURRENTLY ACROSS NORTHERN UTAH. THEREFORE
CONFIDENCE IS MODEST AT BEST IN SPECIFIC TIMING/AREAL EXTENT OF
ADDITIONAL CONVECTION AND ALSO TO MAX TEMPERATURE POTENTIAL.
FOR NOW...MOISTURE/PWAT VALUES WILL REMAIN RELATIVELY HIGH NORTH
OF THE LOW LEVEL BAROCLINIC ZONE BEFORE UPPER TROF LIFTS OUT AND
WEAKENS ACROSS THE CENTRAL PLAINS ON MONDAY NIGHT. THEREFORE WILL
CONTINUE TO SHOW RELATIVELY HIGH POPS...THOUGH GRADUALLY LESSENING
THROUGH THE EARLY WEEK PERIOD. LITTLE CHANGE TO GOING TEMPERATURE
FORECAST FOR NOW.

GENERALLY A DRY AND MODERATE TEMPERATURE REGIME FOR THE MID-WEEK
PERIOD...WITH WEAK NORTHEASTERLY COMPONENT LOW LEVEL FLOW ACROSS
THE AREA. A FAIRLY STRONG UPPER TROF PROGGED TO MOVE ACROSS THE
NORTHERN ROCKIES BY FRIDAY...WHICH MAY ALLOW COLD FRONT TO PUSH
INTO THE AREA BY THE WEEKEND. FOR NOW CONSENSUS WAS TO ADD SLIGHT
POPS FOR THE END OF THE WEEK...HOWEVER A LOT OF MODEL RUNS TO
MAKE TWEAKS TO BOTH TEMPS AND PRECIP BEFORE THEN.
