Modest Model Failure
The numerical models from this morning and earlier underplayed the precipitation over the region. The latest runs appear to have caught up with reality with light precipitation this evening. As a result we are seeing a wintry mix of rain, rain/snow mix, and some light snow over the lowlands, particularly north of Seattle. There is a dusting at some locations right now..particularly above 200-300 ft. The latest 24-h snowfall from the latest high resolution model is attached. Amounts up to around 1 inch are possible..but I suspect that such values will be on the high side. So no big snowstorm, but light snow is possible tonight. The precipitation should be over by 10 AM tomorrow.
