...TEST...TEST...TEST...

FIRST...AWIPS IS SICK AGAIN.  SOME PRODUCTS COME IN BUT OTHERS DO
NOT.  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.  BY TUES
MORNING ATM APPEARS TO BE TAPPED OUT BUT STG BAROCLINIC ZONE ACROSS
NRN KS COULD BE THE FOCUS FOR MORE CONVECTION WEDS AND ESPECIALLY
THURS PM AS ANOTHER 700 MB WAVE APCHS FCST AREA.

.LBF...NONE.
