Incorrect weather data

[phuz]

I added this temporary event until we figure this out.

Had to switch to NOAA instead of Wunderground. Getting that original forecast change multiple times a day again. Driving myself and wife crazy. Even the kids are getting confused when they see "snow" on a 70 degree day.

[phuz]

Now stuck between a rock and a hard place. The NOAA weather doesn't give precip % for the forecast, AND it's not populating the Day 0 and Day 6/7 stuff properly. With the WU forecast continually screwing up, I thought maybe generating a new API key would fix it. Nope!

[phuz]

This is driving me nuts, so I think I am going to just code my own JSON calls to get the data I need and store it in respective arrays.

Since others have shared the same issue, have you considered using JSON instead of the XML files?

What is the URL you are using based on our chosen weather stations?
I can navigate to this:
http://api.wunderground.com/api/<API...PA/Reading.xml

but when not sure the URL for a specific station (ie, KPAMOHNT9).

[phuz]

I wrote a class library to grab all the JSON data and I must say, this works great.
I'll add another function for getting the current conditions but not in a hurry since the current conditions were never an issue.

    Public Sub GetWUForecast()
        ReDim HomeLow(8)
        ReDim HomeHigh(8)
        ReDim HomeName(8)
        ReDim HomePrecip(8)
        ReDim HomeImageURL(8)
        ReDim HomeForecast(8)
        Dim myreq As HttpWebRequest = HttpWebRequest.Create("http://api.wunderground.com/api/[B]{my api key}[/B]/forecast10day/q/PA/Mohnton.json")
        Dim myResp As HttpWebResponse
        Dim mywebheadercollection As WebHeaderCollection = myreq.Headers
        Dim post As JObject
        myreq.Method = "GET"
        myreq.ContentType = "application/json"
        myResp = myreq.GetResponse
        Dim myreader As New System.IO.StreamReader(myResp.GetResponseStream)
        Dim myText As String
        myText = myreader.ReadToEnd()
        Dim i As Integer = 0

        post = JsonConvert.DeserializeObject(myText)
        For i = 0 To 8
            HomeLow(i) = post.SelectToken("forecast.simpleforecast.forecastday[" & i & "].low.fahrenheit")
            HomeHigh(i) = post.SelectToken("forecast.simpleforecast.forecastday[" & i & "].high.fahrenheit")
            HomeName(i) = post.SelectToken("forecast.simpleforecast.forecastday[" & i & "].date.weekday_short")
            HomeImageURL(i) = post.SelectToken("forecast.simpleforecast.forecastday[" & i & "].icon")
            HomeForecast(i) = post.SelectToken("forecast.simpleforecast.forecastday[" & i & "].conditions")
            HomePrecip(i) = post.SelectToken("forecast.simpleforecast.forecastday[" & i & "].pop")
        Next
    End Sub

I suspect that the json will have the same issue as the xml file. The data is coming from the same source The only difference in the URL used to get the file is the ending.
URL.json vs URL.xml

The source data is the same.

Yeah, I noticed that. But I'm keeping a close eye and I'll let you know.

I noticed this same problem on my system today. The weather forecast was for Wednesday instead of Friday (today)...two days behind.

A few hours later it said Sunday...two days ahead.

Lets give it a week and if switching to the JSON feed fixes it for phuz, then I will change weatherXML to use the JSON feed.

I have the weather underground app on my phone. It is showing that the temperature here is 103 degrees. The other weather app I have says it is 83.

Checking some websites shows that the 83 is correct.
wunderground.com says it is 81 but their app is still showing 103.

[peterpc]

Having the same problem.
Temp is too low.
Manual update sometimes fixes the problem, but it keeps comming back.

I am still getting errant weather forecasts. Any word on a fix?

As far as I know WU won't be fixing this. They are non-existant in their forums. Even the customers that are using the pay service are seeing this.
And it has been reported in both the xml and the json service.
Their own phone app is reporting wrong temperatures at times. As I posted above the app was reporting that the temperature was over 100 when it was actually in the 80s.

The only work around that has been mentioned is to check the date in the download and if it is not todays date then ignore the file and wait until the next normally scheduled run to see if the forecast data has been corrected.
I plan on implementing this workaround.

I haven't seen these problems (yet), but I am becoming concerned over the declining quality of services from WU, since their purchase by TWC. WU is the premier host of personal weather stations(PWS), but that no longer seems to be important enough to them to continue to provide service on par with that standing.


Since I'm currently trying to decide on a PWS, I'm concerned about the dependence of PWSs reporting to a third party (like WU), to make their data available to software.



Is it too early to start brainstorming a "Plan B?" Or, is Ambient positioning themselves to be the fall-back position?

I'm having the same problem. Data is being shown from January and is corrected by re-runing the scripts to download the data after some period of time.
