SD AND THE MIDWEST. SIGNIFICANT UNCERTAINTY CONTINUES IN THE FCST QPF AMOUNTS AS WATER VAPOR CLEARLY INDICATES TROPICAL MOISTURE IS SURGING NORTH OFF THE ITCZ LOCATED AT 10N AND HEADING FOR THE CENTRAL U.S.. THE COMBINATION OF THIS MOISTURE...NEARLY 300 PERCENT OF NORMAL...AND ARCTIC AIR SUGGESTS A RECORD EVENT IS UNDERWAY BUT MYSTERIOUSLY NONE OF THE MODELS SUGGEST MUCH MORE THAN YOUR TYPICAL HP WINTER STORM EVENT. THE OFFICIAL FCST CALL FOR AN ICE STORM WARNING FROM CHAPPELL NORTHEAST TO AINSWORTH AND BUTTE INCLUDING ALL AREAS TO THE SOUTHEAST. THIS IS VERY LIBERAL CONSIDERING THE BLENDED MODEL SOLNS OF THE NAM12 AND GFS WOULD SUGGEST A WARNING LESS THAN HALF THIS SIZE BUT MOISTURE ADVECTION...WINDS ALOFT AND INTENSE WARM AIR ADVECTION SUPPORT THIS CAUTIOUS FCST.

NONE OF THE MODELS SUGGEST HEAVY SNOW WILL DEVELOP...LIKELY BECAUSE OF THE LACK OF FRONTOGENETICAL FORCING. BUT LATER FCSTS WILL HAVE TO CLOSELY MONITOR THE POTENTIAL FOR CONVECTIVE DEVELOPMENT AS H75MB LIFTED INDICES ARE CLOSE TO ZERO FROM KIML NEWD THRU KONL AND SOUTHEAST SATURDAY AM. MEANWHILE THE GFS SUGGESTS AN AREA OF NEGITIVE EPV LIFTING QUICKLY NORTH BETWEEN 12 AND 18Z SATURDAY ACROSS THE SAME AREA.
