   ...NO SVR TSTM AREAS FORECAST...
   
   ONGOING CONVECTIVE ACTIVITY IS ALREADY DIMINISHING WITH LOSS OF
   DAYTIME HEATING...BUT SOME RISK OF ADDITIONAL THUNDERSTORM ACTIVITY
   WILL PERSIST IN SCATTERED AREAS OF THE COUNTRY THROUGH THE NIGHT.
   
   ...MISSISSIPPI VALLEY...
   MOIST CONDITIONALLY UNSTABLE AIR MASS REMAINS PRESENT IN TONGUE
   ALONG/EAST OF MID-LEVEL SHEAR AXIS ACROSS THE CENTRAL STATES.  SHEAR
   AXIS/WIND SHIFT HAS SURGED EASTWARD ACROSS THE UPPER MISSISSIPPI
   VALLEY INTO THE UPPER GREAT LAKES REGION...BUT HAS BECOME
   QUASI-STATIONARY ACROSS THE LOWER MISSOURI VALLEY AND SOUTH CENTRAL
   PLAINS...NORTH/NORTHEAST OF CLOSED LOW WHICH HAS DEVELOPED OVER
   CENTRAL TEXAS. MODELS SUGGEST CLOSED LOW WILL BEGIN TO SLOWLY
   ACCELERATE NORTHEASTWARD TOWARD THE OZARK PLATEAU OVERNIGHT...AS
   LARGE-SCALE UPPER TROUGH CONTINUES TO SLOWLY AMPLIFY OVER THE
   NORTHERN ROCKIES/PLAINS.  THIS WILL CONTRIBUTE TO ZONE OF ENHANCE
   UPPER DIVERGENCE FROM THE MISSOURI OZARKS INTO NORTHWEST ILLINOIS/
   NORTHWEST IOWA...WHERE POTENTIAL FOR NEW CONVECTIVE DEVELOPMENT
   APPEARS BEST.
   
   ...MID ATLANTIC COAST...
   SCATTERED CONVECTIVE DEVELOPMENT MAY ALSO PERSIST THROUGH THE NIGHT
   ACROSS NORTHERN MID ATLANTIC COASTAL AREAS.  THIS WILL BE ASSOCIATED
   WITH INFLUX OF TROPICAL MOISTURE ALONG/NORTH OF MID-LEVEL
   CIRCULATION NOW MIGRATING OFF THE WESTERN ATLANTIC INTO EASTERN
   NORTH CAROLINA.
