DAY 4-8 CONVECTIVE OUTLOOK

0353 AM CDT TUE MAY 08 2007
VALID 111200Z - 161200Z
..NRN AND CNTRL STATES...
MEDIUM RANGE MODEL FORECASTS ARE SOMEWHAT IN AGREEMENT BUILDING AN
UPPER-LEVEL RIDGE IN PLACE ACROSS THE CNTRL STATES EARLY IN THE DAY
4 TO 8 PERIOD. THE DEVELOPING RIDGE WOULD SHIFT THE STRONGER
MID-LEVEL FLOW NWD INTO THE NRN STATES ON FRIDAY AND SATURDAY WITH
THE LARGE-SCALE PATTERN LIKELY PERSISTING INTO EARLY NEXT WEEK. THIS
WOULD INCREASE THE SEVERE POTENTIAL ACROSS THE NRN HIGH PLAINS...NRN
PLAINS AND UPPER MIDWEST FOR MUCH OF THE DAY 4 TO 8 DAY PERIOD. AT
THIS POINT...MANY QUESTIONS REMAIN ACROSS THE NRN STATES INCLUDING
THE TIMING OF SHORTWAVE TROUGHS MOVING OVER THE TOP OF THE RIDGE AND
THE AMOUNT OF INSTABILITY. THE CNTRL PLAINS WILL LIKELY HAVE MORE
INSTABILITY BUT THE SEVERE THREAT THERE WILL DEPEND ON HOW STRONG
THE UPPER-LEVEL RIDGE BECOMES. AS A RESULT...CONFIDENCE IS TOO LOW
TO FORECAST AN AREA WITH AN ENHANCED SEVERE WEATHER THREAT ATTM.
