10/2/2019 7:00 AM 0.05 T M T M cold surfaces had 0.4 inch of snow on them but just a trace on the boards. Snowfall picked up right at measuring time so more accumulation will occur this morning.
10/3/2019 7:00 AM 0.03 0.4 0.04 M M Snow fell between 7AM and 9AM and melted shortly after. Catch in the gauge was 0.03 but melted core total at 9 AM was 0.04 inch.
