THE UPPER MIDWEST AND MID MO RIVER VALLEY DURING THE DAY 3 PERIOD.
AN ASSOCIATED COLD FRONT EXTENDING SSWWD FROM A LOW OVER S-CNTRL
CANADA INTO THE CNTRL HIGH PLAINS...WILL MOVE EWD ACROSS PORTIONS OF
THE NRN AND CNTRL PLAINS STATES DURING THE DAY AS SLY LOW-LEVEL FLOW
TRANSPORTS A NARROW PLUME OF MODEST LOW-LEVEL MOISTURE NWD INTO THE
CNTRL PLAINS.  ISOLATED THUNDERSTORMS ARE FORECAST TO PRIMARILY
DEVELOP DURING THE AFTERNOON/EVENING OVER THE CNTRL PLAINS AND
PERHAPS LATER FARTHER E AND S OVER WRN MO AND OK.  MODEST MID-LEVEL
LAPSE RATES AND LIMITED MOISTURE WILL LIKELY NEGATE APPRECIABLE
SEVERE POTENTIAL ACROSS THE PLAINS STATES.
