Title: Snow forecast
Post by: Chet on January 23, 2013, 10:09:06 PM

 [snow]My weathercat has been running now for five days. It keeps saying snow in the next 12 hours, possibly heavy. This no where near accurate. Can anyone explain?

Thanks.

Hi Chet,
That's the forecast that comes from the hardware. Check you have your coordinates set correctly in the console - the console uses these when calculating the forecast and if they're wrong you may be getting weird forecasts.

Even if you have provided all the correct information, the Davis forecasts are   . . . .  dubious at best.  Davis doesn't explain, but it appears to be a refinement of the Zambretti Forecaster.   You can read more about that here:

It is simply a very impoverished strategy for forecasting the weather.  In Northern California (where Davis is located by the way) it is very rarely - right!

I would hope it works better in England, Northern France and places near where the original tool originated, but I'm not even sure this is true.

Hope this reassures you some.
