It's official! Our first measurable snowfall happened. We had 7.3" (18.5 cm) of #snow accumulation at our measurement this morning.

It looks like we're done with snow for at least the next 10 days but we'll be watching the forecast excitedly.

Not enough #snow for a measurement this morning because we only measure accumulation greater than 0.5 cm (0.2"). Something tells us we'll have enough within the next 24 hours though...
