THIS SYSTEM MAY AFFECT THE WRN CWA LATER THIS EVENING...MOVG THRU THE BROOKINGS AND SW MN AREA JUST BEFORE MIDNIGHT. NOT A GREAT CHC OF RAIN...BUT CANNOT RULE IT OUT.

THE ETA HAS NUKED THE PCPN DESPITE THE ABOVE MENTIONED PROBLEMS... BUT NOT THE GFS HAS PICKED UP ON THE QPF WITH A CONVECTIVE LOOKING INDUCED VORT MAX SATURDAY AFTN. THEREFORE...CONT TO GO CHC POPS OVER THE SRN CWA FOR SATURDAY...ESP IN THE AFTN. ETA/GFS ARE IN GOOD AGREEMENT ON BRINGING ANOTHER S/W THRU THE ZONAL FLOW SATURDAY NIGHT. THIS ONE COULD BE STRONG AND WORTH STRONG CHC POPS. THIS SATURDAY NIGHT WAVE EXITS RAPIDLY...AND BEHIND IT MID LVL WAA USHERS IN FOR MUCH OF THE DAY ON SUNDAY. MUCH OF THE CWA IS CAPPED OFF AGAIN WITH +12 TO +14C AIR AT H7. HOWEVER BOTH MODELS THEN SHOW ANOTHER VERY VIGOROUS DISTURBANCE AND ASSOCIATED CDFNT MOVG INTO THE AREA SUNDAY NIGHT. THIS WAVE HAS BEEN WELL ADVERTISED...AND IS CRNTLY ON THE WV IMAGERY IN WRN CANADA. COULD BE SOME MORE SVR TS WITH THIS ONE SO WILL KEEP AN EYE ON IT.

LOW LVL BNDRY THEN CONTINUES TO LAY OVER FM W TO E ACRS THE SRN CWA ON MONDAY AND MONDAY NIGHT...WHICH WL KEEP A CHC OF TS/SHRA GOING FM I 90 SWRD IN THIS TIMEFRAME. ...LONG TERM... OVERALL...MODELS CONT TO BE IN GOOD AGREEMENT WITH THE LARGE SCALE FEATURES. THE LAST IN THE SERIES OF S/WS MOVES THRU ON TUE AND TUE NIGHT. THIS IS FOLLOWED BY SOME SUBSTANTIAL RIDGING BUILDING JUST TO THE WEST OF THIS AREA...POTENTIALLY CAPPING THINGS OFF LATE IN THE WEEK. NEW GFS RUNS POINTED TO SOME QPF IN THE SIOUX CITY AREA ON THURSDAY. HARD TO HANG MY HAT ON THIS RIGHT NOW SO WILL REEVALUATE TOMORROW. .FSD...NONE MJF
