Forecast issues

Weather underground forecasts are currently not updating consistently for me. I know my api key works because my other apps that use it to pull forecasts are working just fine. Current weather information does not seem to have an issue, but the forecasts are not pulling properly. Anything relying on a forecast tag is blank multiple times through the day, and the app says forecast data not available when I look at the widget in edit mode. Sometimes forcing a manual update fixes and other times it doesn't. This started maybe 4-5 days ago. I have uninstalled and reinstalled the app with no change.
