Using this decoder I get:

4/011: the snow depth on the ground, 11 inches

11006: the maximum temperature since 6 hours, -0.6 °C

21017: the minimum temperature since 6 hours, -1.7 °C

53013: the pressure change since 3 hours, +1.3 hPa, having decreased or steady, then increased; or increased, then increased more rapidly.
