I'm a weather buff... around here, it is quite common during the night for the current location METAR nearest to me to stop updating at night. The Airport related to it is closed late at night. Kinda weird when at 4am it says it is 108?F when it is only 94?F.
Not really impressed with most of the weather apps as they deal more with forecast info than actual current data. I'm more interested in current weather, not what is coming. Most METARS only update every 15 minutes or longer so they are only snapshots of what is happening at best.
Hitting my own weather station provides much more accurate information and updates once a minute, though I normally only look at it on demand. Use a simple mobile web page to get that, only takes a sec or to to load with tons more data than a typical weather app displays.
As for your problem, There are a lot of reasons why your weather may not be updating. Not sure I would hit it 70 times... would be easier to just hit one of the weather websites.
