"Portland Metro Area Faces Unlikely Valentine's Day Snowfall Emergency"

The Portland National Weather Service has issued a Winter Weather Advisory for the metro area, despite slim chances of sticking snow in the lowest elevations west of the Cascades. The advisory is based on a 10% chance of 6-10" snow, primarily due to one model's slightly higher probability, although other models predict temperatures above freezing with rain at times. Concerns have been raised about the new probabilistic forecasting method potentially leading to the "crying wolf" issue, as emergency managers need access to worst-case scenarios, but it could become the forecast everyone gravitates toward.
