THE NON-INSTRUMENT RATED PRIVATE PILOT DEPARTED ON A VFR CROSS COUNTRY FLIGHT IN VFR WEATHER CONDITIONS. ABOUT 9 MINUTES AFTER HE TOOK OFF, THE PILOT TOLD AIR TRAFFIC CONTROL (ATC) THAT HE WAS ENCOUNTERING SNOW FLURRIES, AND REQUESTED ANY PERTINENT UPDATED WEATHER REPORTS/PILOT REPORTS. ATC REPORTED SCATTERED LIGHT SNOW SHOWERS IN THE AREA, BUT HAD NO OTHER SIGNIFICANT INFORMATION AVAILABLE. ELEVEN MINUTES LATER THE PILOT REPORTED HE WAS LOSING GROUND CONTACT IN HEAVY SNOW AND REQUESTED VECTORS BACK TO THE DEPARTURE AIRPORT. THAT WAS THE LAST TRANSMISSION FROM THE ACCIDENT AIRPLANE.
