If forecasting could be "learned" by the VP2, I think it would require feedback. For example, if the original forecast is for heavy rain within 4 hours, then conceivably, any actual rain measured, could be used to adjust the forecasting methodology. I doubt that this "learning" capability is built into the console - it would require some pretty fancy programming. And wouldn't Davis be touting the capability in their marketing?

And, some of the built-in forecasts, such as cloudy weather, aren't measured, unless optional solar measurement is added.

I wonder if any perceived forecasting improvement over time is an illusion due to human factors.

In case you're unaware, you're replying to a 4 1/2 year old thread.

How often do people actually press the forecast button on their console to see the forecast? Even though I obviously know it's not extremely accurate (most of the time), I usually look at it everyday, just for the hell of it, and because it's a cool feature.

I look at my console maybe once a day, and never at the forecast.  I use my weather computer for the Davis forecast AND other better forecasts...

In my neck of the woods, the forecast function that the Davis console supplies is at the very least, laughable. Very rarely correct, however, considering all of what it uses for deduction, no surprise. All in all, basically worthless.
