ANOTHER BOUNDARY IS SITTING ACROSS FAR SRN NEB AND STORMS ARE FIRING ALONG THIS BOUNDARY ACROSS SOUTH CENTRAL NEB NOW. STORMS CONTINUE TO FIRE ACROSS WARM FRONT IN NERN KS AND ALONG OUTFLOW ACROSS NWRN MO. THIS ONGOING CONVECTION HAS KEPT MID 60S SFC DEWPOINTS FROM REACHING OUR FORECAST AREA THIS AFTERNOON...THUS LIMITING OUR INSTABILITY AND KEEPING STRONG CONVECTION TO OUR SOUTH. AS WAS EXPECTED...WE HAVE SEEN A LULL IN ACTIVITY ACROSS MUCH OF THE CWA EARLY THIS AFTERNOON AS A WEAK DRY SLOT HAS WORKED INTO THE AREA AS WAS SUGGESTED BY THE 12Z NAM.

THE WATCH AREA COVERS THOSE COUNTIES THAT HAD SIGNIFICANT RAINS LAST NIGHT AND THUS ONE HOUR FLASH FLOOD GUIDANCE IS NEAR OR LESS THAN 1 INCH. STILL FEEL THAT HEAVY RAIN IS POSSIBLE ACROSS MUCH OF FORECAST AREA...HOWEVER THOSE AREAS THAT DID NOT RECEIVE RAINFALL LAST NIGHT SHOULD BE ABLE TO HANDLE AN INCH OR SO OVERNIGHT WITHOUT MUCH FLOODING CONCERN.
