Display National Weather Service Observations

[Austin Althouse]

Hello,

I am making a weather application that I want to display weather observations from the National Weather Service using their API. I am already getting forecasts from this API and I am trying to use the same code layout but the problem is where it says periods is not the same and it says features. Here is my code:

Private Sub NWS_Conditions()

Using WB As New WebClient
Try
WB.Headers.Add("User-Agent", "NWIDC Digital HD/v1.0 (website; email")
Dim ObservationData As String = WB.DownloadString($"https://api.weather.gov/zones/forecast/{My.Settings.NWS_Wx_Forecast}/observations")

Dim weather As WeatherData = JsonConvert.DeserializeObject(Of WeatherData)(ObservationData)

Dim features As features = New features

Label15.Text = weather.periods(0).detailedForecast
Label41.Text = weather.periods(0).name
My.Settings.Forecast_Time = weather.periods(0).name

Label17.Text = weather.periods(1).detailedForecast
Label18.Text = weather.periods(1).name
My.Settings.Forecast_Time_2 = weather.periods(1).name

Catch ex As Exception
End Try
End Using
End Sub

Where it says forecast will be replaced, where it says features is where I am stuck at. I want to be able to display the observations in their own label and have the icon display in a picture box. Here is the NWS's JSON file.
