SHORT TERM...
18Z SURFACE ANALYSIS SHOWS PLENTY OF MOISTURE ACROSS THE CWA WITH
MAIN AXIS OF 65+ DWPTS RIDING ALONG SFC TROF IN WRN KS. VSBL SAT
PIX INDICATE SCT TSRA BEGINNING TO DEVELOP THERE. FIRST QUESTION IS
WILL THESE STORMS MAKE IT INTO CNTRL/SC KANSAS. CONSIDERING THETA-E
RIDGE SLIDES EAST AND 85H SOUTHERLY JET SHIFTS EAST TO SC KANSAS
WILL CONTINUE CHC OF TSRA IN SC/CNTRL KS. 12Z SOUNDINGS SUGGEST
CAPES NEAR 3000 J/KG AND IMPRESSIVE HODOGRAPHS WITH POTENTIAL FOR
SUPERCELLS AND SR HELICITIES 250+...THUS WILL ALSO MENTION CHC FOR
SVR.

NEXT CONCERN IS MCS POTENTIAL FOR SE KANSAS. MODELS AGREE WITH
EXCELLENT 1000-500 MB THICKNESS DIFFLUENCE ACROSS SE KANSAS AND GOOD
WAA AT BOTH 850 AND 700 MB. SO ANY CONVECTION THAT FORMS IN CENTRAL
NE WILL LIKELY MOVE SE ALONG WRM FRONT IN NE KS/WRN MISSOURI. STILL
WILL CARRY CHC TRW IN SE...BUT WITH BEST THETA-E RIDGE REMAINING
WEST OF THIS AREA AND MAIN BOUNDARY TO THE NORTH AND EAST...FEEL
FLOODING THREAT IS MINIMAL.

AS FOR TEMPS WITH DWPTS ACTUALLY RUNNING A TAD LESS THAN FWC 3 HR
FORECAST WILL SHAVE A DEGREE OR SO OFF FWC NUMBERS...BUT STILL GO
ABV COOLEST FAN NUMBERS.
