Overall, yes to progress. However, please bring the wind strength graph back. It was enormously useful for sailors.

@idefix37 you picked one of my favorite weather stations. :-)

Yes I've seen that feature. It's intriguing as it hints at the kind of feature I would like to see.

The comparison is made against presumably the last / most recent forecast before the observation. So that might be 1hr before the observation. That's not a very interesting forecast point – "is this model accurate 1hr out" is not a high value question. :-) – I'm interested in what the forecast said, say, 24hrs before the observation.

And yes, I'd expect this to involve some additional data retention.

Long time Windy subscriber (and user) here.

We're sailors, and it's -super useful- to track the forecast for a particular day & location as it evolves.

Use case:

• I have a regatta in Biscayne Bay, Florida, USA on a Saturday 10 days away.
• "Mark this spot to capture" daily snapshots for the next 10 days of what the wind forecast is for the available models
• Review UI - of how the forecast has evolved day to day - is it stable, is it strobing, is it all over the place?
• After the target date has passed, post-mortem review: how did this model, at this point in time, track against observed weather at a nearby weather station (say, VAKF1 for Biscayne Bay FL).

We might be able to say, based on reviewing the data, things like

• "GFS 48hrs out was spot on"
• "ECMWF was mostly stable over the 10 days, and was close to the observed conditions"
• "ICON was accurate on the timing of the afternoon wind shift, 24hrs out"

We race in locales with stable forecasts, and in locales with... less stable forecasts. We know the date we'll be sailing. Sometimes it's accurate for an East wind, and a West wind means lower accuracy.

I would expect similar things for VFR flights, oceanic crossings – you know you want to fly or sail on this date and time – not just what's the forecast at this point in time, but is it stable, is it reliable?

If any of this is useful, interesting, happy to flesh out the use cases more. Not a trivial feature req. But it seems to me that you have all the underlying bits of data and UI parts.

It'd need additional storage for the requested captures – but that it'd also be a useful paid feature to offer, and a sticky feature too, a reason for customers to stay subscribed.

My interest is weather patterns in a 20 mile radius, not in a 1000 mile radius.
