Apologies, I forgot to sign the CLA. It is now done.

You also need to update all other tests to include a zero snow field.

Those aren’t required because the snow property isn’t returned if the field is zero. Same with the rain forecast.

I signed the CLA again.

Anyway, the tests are now failing. They need to be fixed in order to get this merged.

Correct, and by running that command, the CLA test is re-run and now succeeds.

I will correct the tests. I didn’t see them failing previously when I ran them on my box. I probably missed the commit.

The test server on windows appears to be failing. Hopefully that won’t be held against me. 😀
