WB 12Z GFS storm totals

WB 12Z GFS snow totals 4 pm Sunday; everything has changed to sleet by this time

Last time I can remember this much sleet/ ice was Superstorm 93 when I was in my 20s and living in PG. Can remember "skating" in my backyard on ice crusted snow. It was great!

WB 3K NAM

Will post 3K when it finishes.

WB 3K NAM also looks to dry slot with a period of freezing drizzle/ sleet by Sunday afternoon.

Verbatim, ice by 8am everywhere except far north on WB 12Z 3K NAM; everywhere by 11.

WB 12Z NBM para

My take from HRRR is that the glacier is still coming. Complete your errands today. Roads will be hazardous at least through Monday. Widespread 6 plus inches of snow, with sleet and ice on top of frozen ground. WB 12z HRRR

Actually HRRR could be a worse case scenario, a long duration light freezing rain/ drizzle period.

HRRR is drier this run compared to 6Z. WB 12Z HRRR 4pm Sunday. I guess a new way to fail is to be dry slotted as the coastal transfer takes place.

9am still heavy snow DC with sleet knocking at door.

8am another hour of heavy snow DC

7am still a beat down DC WB 12Z HRRR
