APPEARS WERE ABLE TO TRANSMIT SO FOR NOW WERE OPERATIONAL FOR THE MOST PART. NO SFC OB PLOTS...NO PROFILER...INTERMITTENT SATELLITE...ETC. PRESUMABLY THE COLD FRONT WILL CONTINUE WORKING SWD THROUGH THE HIGH PLAINS THIS EVENING. MESOETA IS THE CHOICE...COORD WITH CYS AND A LOOK AT INTERMITTENT IR DATA INDICATES FRONT AND UPPER DIVERGENCE ARE BEGINNING TO INTERACT. LOOKS LIKE SCATTERED HIGH BASED CONVECTION THIS EVENING ACROSS NORTHERN ZONES BUT WEAKENING AOA 06Z-09Z. FRONT THEN DRIFTS SWD WITH INCREASING MOISTURE CONVERGENCE ALONG AND NORTH OF FRONT ON SUNDAY. EXTENSIVE MID LEVEL CLDINSS ASSOCIATED WITH MOISTURE POOLING SHOULD INHIBIT WARMING. FAR SRN ZONES COULD STILL GET INTO THE 90S...PERHAPS WARMER WITH FULL SUN. ALL MODELS THEN PICK UP ON THE APPARENT MCV OVER SCNTL CO THIS AFTN AND TRACK IT ACROSS NEB SUNDAY NIGHT. TRACK POSITION AND ASSOCIATED PCPN VARIES...THOUGH. WILL SIDE SOMEWHAT WITH AVN AND GO WITH HIGHER POPS NORTHWEST AND NCNTL WITH LOWER POPS SOUTH. PCPN SHOULD LINGER INTO MONDAY WITH SLOW MOVING STORMS. AVN THEN WOULD FEATURE A SECOND VORT STREAM PRODUCING MORE SCATTERED CONVECTION MONDAY AFTERNOON AND NIGHT ACROSS NORTHERN TIER COUNTIES. ALL OF THIS ACTIVITY FOCUSING ALONG AND NORTH OF THE 850 MB FRONT DRAPED ACROSS SRN NEB.
