NAM INDICATED AXIS OF 2000-3000J/KG CAPE ORIENTED NORTHWEST-SOUTHEAST THROUGH THE FORECAST AREA BETWEEN ABOUT 21Z-03Z AS WARM FRONT LIFTS NORTHWARD. LATEST RUC MODEL DID NOT INDICATE THESE HIGH SBCAPE VALUES...BUT HAD HIGHEST INSTABILITY FURTHER SOUTH OF THE FORECAST AREA. CURRENT LAPS SBCAPE VALUES SUPPORT NAM OUTCOME...THUS STORMS COULD INITIATE NEAR MISSISSIPPI RIVER AND EASTWARD ALONG WARM FRONT...THEN PROPAGATE NORTHEASTWARD. MOST WIND SHEAR FAVORED LOWEST 0-3KM LAYER...WITH VALUES AROUND 40KTS. THIS SUPPORTED POTENTIAL FOR SUPERCELL MODE INITIALLY...THEN EVOLUTION INTO BOWING LINE SEGMENT AS COLD POOL CONGEALS. DAMAGING WINDS AND LARGE HAIL PRIMARY THREAT... ALTHOUGH AN ISOLATED TORNADO POSSIBLE IN BACKED SURFACE FLOW NEAR WARM FRONT. IN ADDITION...THE FORECAST AREA COULD HAVE STORMS MOVING NORTHEASTWARD FROM IOWA/MISSOURI AREA DURING THE OVERNIGHT HOURS... WHICH COULD SPELL MORE SEVERE WEATHER POTENTIAL. PLEASE REFERENCE LATEST LOCAL HAZARDOUS WEATHER OUTLOOKS AND SPC MESOSCALE DISCUSSIONS AND CONVECTIVE OUTLOOKS. SUNDAY...SEVERE WEATHER POTENTIAL EXISTS ONCE AGAIN WITH APPROACH OF COLD FRONT.

AGAIN...STORM MODE COULD INITIALIZE WITH SUPERCELLS...THEN EVOLVE INTO BOWING LINE SEGMENTS. BY 00Z MONDAY...APPEARS FRONT SHOULD BE EXITING FORECAST AREA...TAKING ANY LINGERING STORMS WITH IT. TUESDAY...ANOTHER POTENTIAL SEVERE WEATHER DAY WITH EAST-WEST FRONT IN PROXIMITY TO THE FORECAST AREA...ALONG WITH STRONG VALUES OF WIND SHEAR AND SBCAPE. AS A RESULT...NUDGED RAIN PROBABILITIES UPWARD. .LONG TERM...WEDNESDAY THROUGH SATURDAY MEDIUM RANGE MODELS SUPPORT EAST-WEST ORIENTED FRONT ACROSS THE UPPER MIDWEST...AS UPPER LEVEL FLOW REMAINS PARALLEL TO THIS FEATURE. THUS...SURFACE AND UPPER LEVEL WAVES INTERACTING WITH THE FRONT SUGGEST RAIN CHANCES WARRANTED THROUGH THIS TIME FRAME.
