Well that sucks. I rely on accurate weather predictions for work, and find them to be awfully inaccurate as of late. Figured it was a climate change thing: weather becoming less predictable. But now I see there are other reasons too.

How familiar are you with aviation weather reporting (the TAF to be specific)? They only predict out about 18-24 hours, but should be high-ish quality, right? (I find them to be less useful than they were a decade ago. Not sure if it's just my imagination.)
