THE BIG QUESTION IS HOW THIS SFC FRONT WILL MEANDER OVER THE NEXT 48HRS OR SO GIVEN THAN THE MODELS ARE ADVERTISING THE UPPER JET WILL FOR THE MOST PART REMAIN ORIENTED SW-NE OVER THE CNTRL PLAINS. ALTHOUGH NAM AND GFS NOT SHOWING THIS...LATEST 3KM-HRRR AND RUC13 ARE INDICATING THE FRONT WILL SLOW DOWN AND HANG IN THE VICINITY OF THE SRN CWA THRU LATE THIS MORNING...THEN LIFT BACK NORTH THIS AFTERNOON AS SFC LOW PRESSURE CIRCULATION PUSHES INTO CNTRL KS. THRU TONIGHT THEN...EXPECT SHORTWAVE/VORT MAX MOVING ACROSS THE DAKOTAS WILL NUDGE SFC BNDRY BACK SOUTH AND INDUCE ADDITIONAL CONVECTION ALONG CONVERGENT ZONE IN MOIST/UNSTABLE ENVIRONMENT. BULK OF COLD AIR ADVECTION THEN FILTERS INTO THE CNTRL PLAINS ON FRIDAY WITH MODELS ADVERTISING MOISTURE POOLING/DESTABILIZATION OVER THE SRN CWA IN THE AFTN. SEVERE POTENTIAL APPEARS TO BE SOUTH OF THE CWA...BUT CANNOT DISCOUNT STRONG STORMS DEVELOPING SOUTH OF I-80. DRY AND UNSEASONABLY COOL THEN ON SATURDAY AS SFC HIGH PRESSURE PREVAILS OVER THE REGION.

THUS WILL INCLUDE SMALL OVERNIGHT POPS. DEE && .AVIATION... TAF SITES KOFK/KOMA/KLNK 06Z TAFS SOMEWHAT COMPLICATED FORECAST SCENARIO FOR THE TAFS THIS PERIOD WITH UNCERTAINTIES REGARDING CONVECTION AND EXACTLY WHEN IT MIGHT AFFECT INDIVIDUAL TAF SITES. SCATTERED THUNDERSTORMS MOVING THROUGH THE I80 VICINITY EARLY THIS MORNING LOOKED LIKE IT INITIALLY COULD CLIP BOTH KLNK/KOMA ALTHOUGH NOW APPEARS IT MAY STAY TO THE NORTH...UNLESS NEW CONVECTION DEVELOPS.
