Weather Underground is making changes to their API to pull data off their site. While this will not affect any normal users who use a browser, it will affect anyone who uses 3rd party apps and programs to pull data off Weather Underground. After the change, anyone who uses the API to create programs and apps that pulls data from Weather Underground must pay a license fee. The cost is unknown. However the users who upload their own data gets FREE access to their own data - What a deal!
How will this affect tiffinweather.com? Based on what information is currently available, Personal Weather Station (PWS) owners will still be able to send data to WU, and pull their own data from WU. However they will be unable to make use of the easy-to-use systems to pull data for elsewhere unless they pay a monthly license. Program & app developers will have to pay a hefty fee to make use of the new API and that will probably price them out of existence. "Enterprise Grade" API and related buzzwords are always expensive. As a result on my next maintenance run, I will be terminating the WU feed entirely.
This doesnt bode well for anyone who doesn't work for, or have a hand in a multi-million dollar company. Little people like us as usual will get left at the side of the road. That's my take on it, and you can read the announcement at https://apicommunity.wunderground.com/weatherapi/topics/end-of-service-for-the-weather-underground-api.

Turns out to have access to the data this site previously used would require purchasing an API key for the low price of $400.00 USD a month, more advanced functions would require a more expensive key upwards of $2,000 USD a month. Not going to happen. I expected pricing like this given the words "Enterprise Grade" and the lack of additional details. tiffinweather.com makes $-31 year for domain registration, and hosting and thats ignoring power cost for the local server and hardware required to keep the system online.
