WILL MAKE SOME MINOR UPDATES TO ZONES...BUT GENERAL THOUGHT STILL IS 
ON TRACK.  A SHORT WAVE TROUGH NEAR SIOUX FALLS WILL MOVE EAST ALONG 
THE MN-IA BORDER OVER TOP OF THE RIDGE THIS AFTERNOON.  THERE IS A 
WEAK SURFACE REFLECTION OF THIS FEATURE WITH A LOW LOCATED IN 
SOUTHWEST IA ON THE 15Z ANALYSIS.

THESE SHOULD COMBINE TO HELP PUMP RATHER UNSTABLE AIR NORTH OF THE 
SURFACE BOUNDARY WHICH IS LOCATED GENERALLY ALONG HIGHWAY 34.  THIS 
WILL SUPPORT SHOWER AND THUNDERSTORM DEVELOPMENT THIS AFTERNOON AND 
EVENING...ALTHOUGH 850 MB FLOW IN PARALLEL TO THE BOUNDARY THUS 
FORCING IS NOT VERY DEEP.

THREAT OF HEAVY PRECIP LOOKS MARGINAL BUT SOILS IN SOME AREAS ARE 
NEARLY SATURATED...SO WILL KEEP AN ON THIS AND MARGINAL HAIL THREAT 
NORTH OF THE BOUNDARY.  MORE SUNSHINE AND COOLER MID-LEVEL TEMPS 
COMPARED TO SUNDAY SUPPORT KEEPING SOME POPS SOUTH OF THE BOUNDARY.

.DVN...
IA...NONE.
IL...NONE.
MO...NONE.
