"Let's take a look at a comparison of the temperatures (yellow lines) on both sides of the Cascades (Sea Tac and Yakima) with the normal highs (red lines) and low (blue lines) for the past year." I assume the author means the average over many years for the "normal." The current phrase is like saying "the normal temperate for 1980 did not match the actual temperature for 1980." Or, "1980 was not a normal 1980." Also annoying that the graph has incomplete labels, with the full explanation buried in text.
