VERY STRONG WIND FIELDS AT ALL LEVELS ROTATING AROUND TO E SIDE OF CYCLONE ACROSS MID MO VALLEY INTO UPPER MS VALLEY BY TONIGHT. THIS WILL PROVIDE VERY FAVORABLE DEEP LAYER SHEAR FOR TORNADIC SUPERCELLS AHEAD OF COLD FRONT NOW MOVING INTO ERN NEB SSEWD INTO WRN MO. ...CENTRAL U.S... AN OUTBREAK OF SEVERE THUNDERSTORMS AND TORNADOES WILL DEVELOP AHEAD OF THE INTENSE CYCLONE DURING THE AFTERNOON ACROSS IA/MO AND SPREADING NEWD INTO IL AND SRN WI BY LATE THIS AFTERNOON AND EVENING. 500 MB JET MAX IN EXCESS OF 100KT ROTATES ACROSS MO WITH INTENSIFYING LOW LEVEL JET TO 60KT PROVIDING CONDITIONS FOR TORNADIC SUPERCELLS. AIRMASS WILL BECOME INCREASINGLY UNSTABLE NWD INTO IA AND IL AS MID 60 DEWPOINTS AND TEMPERATURES INTO 70S PRODUCE CAPES TO 2000 J/KG. SEVERE THUNDERSTORMS DEVELOPING RAPIDLY ALONG AND AHEAD OF COLD FRONT FROM ERN NEB INTO WRN MO WILL BECOME MORE WIDESPREAD WITH INCREASING THREAT FOR TORNADIC SUPERCELLS ALONG AND AHEAD OF LINE DURING THE AFTERNOON. GREATEST THREAT FOR SIGNIFICANT TORNADO ACTIVITY WOULD APPEAR TO BE IN AREA OF HIGH RISK DURING AFTERNOON/EVENING. ADDITIONALLY WIDESPREAD WIND DAMAGE IS EXPECTED ALONG SQUALL LINE AS IT MOVES RAPIDLY NEWD INTO UPPER MS VALLEY BY EARLY TONIGHT. ..HALES.. 04/11/01 NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED FOR 2000Z |
