wunderground

My ical Wunderground .ics file no longer shows data.

I tried deleting it and resubscribing at https://ical.wunderground.com/auto/ical/MYSTATE/MYSTATION.ics, but although it seems to download with no problem, the data stops at the end of March.

Have they stopped supporting it?

Is there a replacement weather subscription for ical?

Thanks.
