This major rain event is not shaping up to be a big snow producer in the mountains so far. SWE at mountain stations from midnight on the 7th to midnight on the 8th (last night) shows little change. #waclimate #wawx Data from 🔗 nrcs.usda.gov/resources/data…

Atmospheric rivers tend to be warm, leading to mostly rain rather than snow, even in our mountains. As round two moves in today, we aren't likely to see much improvement in our mountain snowpack as unseasonably warm temperatures continue. Map from: 🔗 nrcs.usda.gov/resources/data…
