Serious Snow Threat Tonight for Puget Sound (and a lot more)

The latest model output supports the threat of serious snow tonight for our region.

The UW's highest resolution forecast model shows substantial regional variations, with the heaviest lowland snow from Seattle northward, with far less over Tacoma.   But there is uncertainty on the exact location of the snow band...so keep that in mind.  Seattle will face 2-5 inches if this forecast is correct.  Road temperatures are now near freezing...so this is going to stick in places where SDOT and WSDOT have not pretreated or where plows are not active.


The very latest NOAA/NWS HRRR forecast (made hourly!) has a similar pattern but only about 1-2 inches over Seattle (see below).  This even does not have the strength to give us mega snow event (8 inches plus, but it will be more than few days ago for many.


The official National Weather Service totals is for 2-3 inches over Seattle, which is quite reasonable.
