KSGF WAS UPGRADED TO RPG AND RDA BUILDS 15.0 THIS WEEK.  AS A RESULT 
OF THIS UPGRADE...A NEW OPTION EXISTS FOR THE DUAL POL BASED 
PRECIPITATION ESTIMATION (QPE) ALGORITHM.  THIS NEW OPTION IS 
EXPECTED TO PERFORM BETTER IN AREAS OF DEEP CONVECTION...AND WILL BE 
ACTIVE FOR THIS WEEKEND'S RAINFALL.  PLEASE NOTE THAT THIS CHANGE 
DOES NOT AFFECT THE LEGACY PRECIPITATION ALGORITHM.  USERS ARE 
ENCOURAGED TO COMPARE BOTH THE DUAL POL AND LEGACY OUTPUT TO GAGE 
READINGS...AND UTILIZE WHICHEVER ESTIMATION IS PERFORMING BEST FOR A 
GIVEN EVENT.
