It has been unseasonably cool here in Kamloops for the last ten or so days.
I follow the forecast temperature graphs on Weather Underground. Because these show a normalised range for the graph, the graph range might be lower or higher than just previous. It is important to pay attention to the scaling.
The graphs look about the same shape each day as they did during high summer: start low, go to maximum during the day, then drop. However, the temperatures are about ten degrees Celsius lower.
Just looking at the graphs is misleading. Labelling counts. A picture may well tell a thousand words, but sometimes, pictures leave out critical words.
