During peak hours, the weather report may appear blank due to high load on our web server. We are working on resolving the overwhelming number of requests for our services.
The weather report may also appear blank if the city you requested is failing to report weather for some reason (eg, a storm blacked out their weather center).
In either case, or if you just don't like your weather, we recommend you do what we do in New England: wait 15 minutes. Then try again.
