TEMPS MAIN FCST PROB FOR TDY.  ATTM NARROW BAND OF SNOW MOVING ACROSS
CWA FM NW TO SE IN ASSOC W/H5 TROF AND SFC COLD FRONT.  THIS SHOULD
MOVE SE OF DSM THEN FALL APART.  88-D ALREADY SHOWING DBZ LEVELS
DECREASING IN THE BANDS AS WELL AS THE BANDS BREAKING UP SO THIS LOOKS
GOOD.  WITH NOTHING BEHIND THIS WK WV SHOULD STILL SEE SUNNY SKIES
TDY.  H8 00Z ANALYSIS SHOWS GOOD COLD POOL N OF ST SLIDING DOWN TDY SO
IT DOESN'T LOOK LIKE THERE WILL BE A TREMENDOUS TEMP RECOVERY DESPITE
SUNNY SKIES.  WAA BEGINS TO MOVE INTO ST TNGT AND WNDS BECOME SE.  RH
INCREASES A BIT AND MID LVL CLOUDS BEGIN TO MOVE IN FOR PTLY CLDY
SKIES.  ON WED CLOUDS INCREASE...MAINLY OVER SRN IA AS SYTEM IN SW US
BEGINS TO MOVE AND EJECT PIECES OF VORTICITY OUT.  SRN STREAM QUITE
STRONG SO DON'T SEE CLOUDS MAKING IT INTO NRN PART OF ST.  FOR NOW WL
NOT MENTION PCPN AS IT LOOKS AS THOUGH THIS WL HOLD OFF TO WED NGT OR
POSSIBLY THU WHEN LOW FINALLY MOVES OUT.  AGAIN...W/STRONG SRN STREAM
FLOW THIS LOW WL STAY WL SOUTH OF IA.  WE MAY SEE SOME OVERRUNNING
PCPN WED NGT AND MORE PROB ON THU SPCLY OVR SE IA BUT AT THIS POINT IT
LOOKS AS THOUGH IT WL BE A RAIN EVENT (DEPENDING ON WHEN PCPN STARTS)
