I'm looking into the National Weather Service's API and trying to get the temperature per hour for the certain location in the next 24 hours.
I'm using the test client to generate the requests:

The temperatures displayed are in 3hour periods. I figured to change the period parameter to 'Weather at a glance'. Indeed I got a time period of 24 hours, but the only parameter displayed in that period was 'Hazards'.
Obviously, each parameter is tied to a time period, but is it possible to get temperature in a 1hour time period instead of 3hour somehow?
Indeed there is a NWS web service that displays data per hour. Just took some time to find it.
