Last Chance for Lowland Snow for the Winter

Get ready to put away the snow shovel.

And you can soon store the bags of salt.

The lowland snow season is about to end.

But we have one more shot tonight...and then it is probably over.

The latest NOAA/NWS HRRR model forecast for total snowfall between now and 9 AM tomorrow morning is predicting little snow over Seattle, but an east-west band of as much as 4-5 inches from Port Townsend to Marysville.  The origin?  A weak approaching weather system and some low-level convergence of air in the north Sound.


Currently, some light showers are moving through (see the radar), but temperatures are too warm for lowland snow.

The freezing level is now (5 PM) around 1700 ft and thus the snow level is about 700 ft.  With the sun going down, the lower atmosphere will cool and an approaching system tonight will bring more showers that will further lower the snow level (from melting and evaporation)  You can see the enhanced area offshore in the latest infrared satellite image:


Saturday and Sunday should be dry with temperatures near 50F.  And next week, temperatures should warm up a bit, something suggested by the last NOAA/NWS ensemble prediction (see below).  No heat wave....but getting close to normal.  But no lowland snow.  

And I need to buy a new snow shovel...mine is a crumpled disaster.
