SHORT TERM OUTLOOK VALID 0600-1200Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...OVER THE LAST HOUR HAVE NOTED A RAPID INCREASE
OF CONVECTION OVER PORTIONS OF NW IA EXTENDING NW TOWARDS PORTIONS OF
SW MN.  THIS APPEARS TO BE DRIVEN BY INCREASING ISENTROPIC ASCENT FROM
STRENGTHENING LLJ COUPLED WITH MODEST LARGE SCALE FORCING FROM SHORTWAVE
TROF NOW OVER PORTIONS OF NE HELPING TO ERODE THE E PERIPHERY OF CAP/EML
OVER THE PLAINS.  WOULD EXPECT CONTINUED CONVECTIVE ORGANIZATION TO
CONTINUE ON THE SHORT TERM AS LLJ/ISENTROPIC ASCENT/MOISTURE TRANSPORT
STRENGTHENS OVER INCREASINGLY FRONTOGENIC SYNOPTIC BOUNDARY.  MOSTLY
UNIDIRECTIONAL PROFILES ABOVE FRONTAL INVERSION WOULD TEND TO SUGGEST
A FORWARD PROPAGATING COMPONENT TO THE SSE.  STILL THOUGH, THE FAVORED
INTERSECTION OF MOISTURE/THERMAL/MOISTURE AXIS NEAR THE NE PERIPHERY
OF MID LEVEL RIDGE AXIS WOULD ARGUE FOR THE POTENTIAL FOR A COMPONENT
THAT MAY TEND TO BACKWARD PROPAGATE/REGENERATE OVER PORTIONS OF SW MN
FOR THE NEXT FEW HOURS WITH DOWNSTREAM TRAINING.  SLOWLY VEERING LLJ
SHOULD THEN SHIFT FAVORED INITIATION POINT DOWNSTREAM INTO PORTIONS OF
CNTRL IA TOWARDS THE END OF THIS TIME PERIOD.  BLENDED PW ANALYSIS HAS
SHOWN A RAPID INCREASE IN MOISTURE THROUGHOUT THE EVENING AND NIGHT ALONG
FRONTAL BOUNDARY AND LOCALIZED HEAVY RAINFALL RATES ARE POSSIBLE WITHIN
FAVORED AREAS OF TRAINING.  GENERALLY USING 12C AT 70H AND E PERIPHERY
OF EML ON GOES SOUNDER AS A GUIDE TO BEST RAINFALL AXIS AND THIS WOULD
TEND TO SUGGEST BEST RAINFALL TOTALS TO EXTEND FROM PORTIONS OF W AND
CTNRL MN SSE THROUGH CNTRL AND PERHAPS SE IA.  THIS IS IN GOOD AGREEMENT
WITH FORECASTS FROM WPC METWATCH AFTER RECENT COORDINATION.
