   ...ND/MN...
   LARGE UPPER RIDGE REMAINS DOMINANT OVER MOST OF THE NATION
   TODAY...WITH BAND OF MODERATELY STRONG ZONAL FLOW ALONG THE
   U.S./CANADIAN BORDER.  SEVERAL WEAK SHORTWAVE TROUGHS ARE EMBEDDED
   WITHIN THIS FLOW FIELD.  ONE FEATURE CURRENTLY OVER WESTERN MT IS
   EXPECTED TO MOVE INTO ND/EASTERN ALBERTA THIS AFTERNOON.  STEEP MID
   LEVEL LAPSE RATES AND INCREASING LOW LEVEL MOISTURE VALUES ARE
   EXPECTED TO RESULT IN AFTERNOON MLCAPE VALUES OF 2000-3000 J/KG. 
   THUNDERSTORMS WILL LIKELY DEVELOP OVER ALB/MAN...EXTENDING SOUTHWARD
   INTO PARTS OF ND BY EARLY EVENING.  SUFFICIENT VERTICAL SHEAR AND
   CAPE WILL SUPPORT A RISK OF LARGE HAIL AND DAMAGING WINDS IN
   STRONGER CELLS.
   
   ...MN/WI/MI...
   LOW LEVEL JET AXIS WILL SHIFT SLOWLY EASTWARD THIS
   AFTERNOON...EXTENDING FROM EASTERN NEB INTO CENTRAL/NORTHERN WI BY
   00Z.  ENHANCED LOW LEVEL WARM ADVECTION AND LIFT NEAR THE NOSE OF
   THE JET IS LIKELY TO AID IN THE INITIATION OF THUNDERSTORMS OVER THE
   ARROWHEAD OF MN.  THESE STORMS WILL TRACK SOUTHEASTWARD TOWARD
   NORTHERN LAKE MI DURING THE EVENING.  MODERATE INSTABILITY AND
   SUFFICIENT DEEP LAYER EFFECTIVE SHEAR INDICATE A THREAT OF
   SUPERCELLS CAPABLE OF LARGE HAIL AND DAMAGING WINDS.  A MORE
   ISOLATED THREAT OF SEVERE STORMS MAY PERSIST INTO THE NIGHT AS
   STORMS MOVE INTO LOWER MI.
   
   ...SOUTHEAST STATES...
   ANOTHER DAY OF STRONG HEATING AND SCATTERED AFTERNOON THUNDERSTORMS
   IS FORECAST TODAY FROM AL/GA INTO THE CAROLINAS.  MORNING SOUNDINGS
   SHOW AMPLE MOISTURE /PW VALUES NEAR 2 INCHES/ AND THE POTENTIAL FOR
   AFTERNOON CAPE VALUES OF 2000-3000 J/KG.  STORMS MAY REMAIN
   RELATIVELY DISORGANIZED DUE TO WEAK SHEAR.  HOWEVER...STRONGER CELLS
   WILL BE CAPABLE OF WET MICROBURSTS.
   
   ...AZ...
   WEAK EASTERLY MID LEVEL WINDS WILL PERSIST OVER SOUTHERN AZ TODAY. 
   THIS AREA IS VERY MOIST WITH MORNING DEWPOINTS WELL INTO THE 60S. 
   SCATTERED AFTERNOON THUNDERSTORMS ARE EXPECTED TO DEVELOP OVER THE
   HIGHER TERRAIN AND SPREAD INTO THE LOWER DESERTS BY EVENING. 
   DAMAGING WINDS WILL BE POSSIBLE WITH STRONGER CELLS.
