This is still happening. The regular past radar (not the future forecast) is wobbling and sliding around the map.

To be clear, I'm not talking about the future radar forecast here. (Although I did complain about that in another thread.)

I'm talking about the regular "past" radar. It never used to wobble around like it is now, and can be seen in the above video.

I understand that forecasting the weather is difficult, but the future radar forecast is completely inaccurate.

Video example:

In this example, the rain system suddenly starting moving rapidly to the east in the forecast, even though it showed no sign of doing so in the past data.

If the forecast is this inaccurate, it should not be made available.

Can we at least have an option to disable it?

Here's a screen recording of the problem.

You can see the radar image wiggling back and forth.

Ever since "the future" was added to the radar slider, the regular "past" radar has degraded in quality. While it's playing, the radar data "wobbles", sliding by tiny amounts randomly over the map underneath.

Any chance of a fix for this? It's quite annoying.

As an aside: Please add an option to remove the "future" from the slider, I live on the US west coast, right on the edge of the radar coverage zone, so it can't see new rain coming in anyway, making the future prediction fairly useless.

When you're viewing a weather forecast of a local model, for example the HRRR in North America, when the limit of the forecast is reached it shows the GFS after it.

Would it be possible to add an option to a different local model instead of the GFS in the forecast? For example, after the HRRR, it would make more sense to show the NAM model for longer range forecasts.

As a a few bands of rain rolled through the SF Bay Area last night and today, I took the opportunity to compare the forecast models as it went through.

I live up in the mountains, and also reasonably close to both the SF bay and the Pacific ocean, so this can be a "challenging" place for forecasts.

Almost all the models forecast continuous rain overnight and through this morning, with the exception of the HRRR, which was by far the most accurate, correctly forecasting long gaps in the rain which were obvious if you were to just look at the weather radar map.

I'm wondering two things:

1. If the ECMWF is really the best default model for the mainland USA?

2. Why the HRRR and NAM models revert to to the GFS once you look too far into the future? Wouldn't it make more sense for them to revert to the ECMWF, if that is supposed to be better?
