SATELLITE ANALYSIS AND TRENDS...GOES WATER VAPOR FOR BIG PICTURE SHOWED
A JET ACROSS THE DAKOTAS THRU N MN AND NORTHEASTWARD THRU JAMES BAY.
MAIN SHORT WAVE NOW COMING ACROSS CENTRAL NEBRASKA AND S CENTRAL SD WILL
LIKELY BE THE TRIGGER FOR CONVECTION ALONG AND JUST SOUTH OF CURRENT
FRONTAL BOUNDARY THAT STRETCHED FROM NE NEBRASKA/EXT SE SD INTO
EXTREME NW IA THRU SE MN AND INTO NW WI AS PER LATEST VIS AND SURFACE OBS.
BEST SURFACE MOISTURE CONVERGENCE FROM NE NEBRASKA THRU
N CENTRAL IA/SE MN INTO N CENTRAL WI AND THIS CORRESPONDS VERY WELL
WITH MAX PW MOISTURE PLUME.  THOUGH MOISTURE TRANSPORT NOT WIDE...IT
IS  EXCELLENT ALONG A NARROW PORTION OF THE BEST MOISTURE AND WILL SET
UP THE POTENTIAL FOR VERY HVY RAIN BURSTS IN TROPICAL AIR MASS ALONG
AND JUST SOUTH OF THE FRONT AS SHORT WAVE COMES OUT OF THE PLAINS THIS
AFTERNOON AND EVENING.  IF THERE IS TRAINING CELLS AHEAD OF THE SHORT
WAVE AND ALONG THE MOIST FRONTAL BOUNDARY...THERE CERTAINLY COULD BE A
NARROW AREA OF EXCESSIVE RAIN WITH TRAINING BURSTS.  AND WITH THE AREA
BEING CLOSE TO MOST VULNERABLE AREAS...THIS WOULD SET UP A NARROW BUT
POTENT FF POTENTIAL AREA FOR LATER THIS AFTERNOON OR THIS EVENING INTO
TONIGHT AS FRONT SLOWLY MOVES SOUTH WITH SHORT WAVE PASSAGE THRU THE
UPPER MS VALLEY.  DRYER AIR/LOWER PWS EXPANDING FROM NE KS INTO NE IA
COULD FURTHER EXPAND INTO SW WI AND HELP DELAY HVY RAINS IN THE
NE IA/SW WI TILL TONIGHT...SO WILL KEEP AN EYE ON THAT...ESPECIALLY SINCE
OUTFLOW BOUNDARY FROM EARLIER THIS MORNING'S UPPER GREAT LAKES STORMS
HAS FAILED TO MAKE MUCH SOUTH PENETRATION THRU INTERIOR NW WI OR SE MN.
