Follow up to this the site weather underground is getting info from for the data http://pbeaudet.us/ As you can see hi low is live with time. I am assuming weather underground is pulling this as well how do i get it?
The High and Low for the day are in the Forecast section "simpleforecast". There is no High and Low in the current conditions because High and Low are forecast. If you use the "yesterday" data in the Anvil plan has the high and low observed data for yesterday.
