...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE NRN PLAINS
/ MIDDLE MO VALLEY INTO THE WRN UPPER LAKES...

CORRECTED TO CHANGE ND TO NEB IN FIRST SENTENCE

...NRN PLAINS ACROSS THE MID MO VALLEY TO THE WRN GREAT LAKES...
LARGE SUPERCELL STORM CONTINUES MOVING SWD ACROSS CENTRAL NEB
ATTM...WHILE OTHER STORMS CONTINUE TO DEVELOP ACROSS NERN NEB AND
VICINITY.  HIGHLY UNSTABLE AIRMASS /4500 J/KG MEAN-LAYER CAPE/
EXISTS ACROSS THE NERN QUARTER OF NEB...BUT DEEP-LAYER WIND FIELD
WEAKENS WITH SWD EXTENT.  THIS COMBINED WITH A FORECAST VEERING OF
LOW-LEVEL JET WITH TIME SUGGESTS THAT THREAT SHOULD BEGIN TO
DECREASE ACROSS THIS AREA LATER THIS EVENING.  UNTIL THEN...VERY
LARGE HAIL AND LOCALLY DAMAGING WINDS CAN BE EXPECTED ALONG WITH THE
POTENTIAL FOR A TORNADO OR TWO.

STORMS ARE ALSO EXPECTED TO DEVELOP ACROSS SERN ND / ERN SD / MN IN
DIFFLUENT UPPER FLOW AHEAD OF STRONG UPPER SHORT-WAVE TROUGH NOW
OVER THE SRN CANADIAN PRAIRIE. AS THIS FEATURE CURVES ESEWD WITH
TIME...STORMS SHOULD MOVE SEWD AND EVENTUALLY AFFECT WI / IA AND
PERHAPS NWRN IL BY THE END OF THE PERIOD.  WITH 60-PLUS KT MID-LEVEL
JET ACCOMPANYING THIS FEATURE...DAMAGING WINDS WILL LIKELY BE THE
MAIN SEVERE THREAT -- PARTICULARLY IF A BOWING MCS CAN DEVELOP ALONG
LEADING EDGE OF AN ORGANIZED COLD POOL.

...AZ...
STORMS CONTINUE PROPAGATING WWD ATTM ACROSS SRN AND CENTRAL
AZ...WHERE TEMPERATURES NEAR 110 AND DEWPOINTS IN THE MID 40S TO
NEAR 50 EXIST. LARGE DEWPOINT DEPRESSIONS / HIGH CLOUD BASES
SUGGEST A CONTINUED THREAT FOR LOCALLY DAMAGING WINDS DRIVEN BY
EVAPORATIVE COOLING FOR THE NEXT FEW HOURS.
