I’ve noticed that Weather Underground tends to overlook storms in Seattle WA. On the other hand, NWS predictions are careful to highlight storms, projecting conditions as bad or worse than the weather we actually get. The Friday / Saturday October 14-15 storm got typical coverage from these services. Compare the Friday morning predictions:
My conclusion; I’d rather prepare for something bad that doesn’t happen (or anyway isn’t that bad) than be blindsided. I’ll enjoy Weather Underground’s cool chart when the weather is mild. But when it gets feisty I’m jumping over to NWS.
