Description
This was a clipper type system resulting in a broader band of snow but very intense snowfall rates. I (Phil) was on mids so I woke up around noon and looked outside and could only see 1/4 mi. That rate lasted for 2 or 3 hours in SiouxFalls. This event was fairly well forecast by the operational models, including HiRes WRF and NMM - all predicted a band at least 48 h out. The location was somewhat uncertain. I believe total snowfall was generally 4-7".
