Channeling Harold Taft: Why This Graphic Cannot Be Correct


Ok, we all should know how a "daily high" and a "daily low" works. It's all based on midnight to midnight. So sometimes you'll hear a brain dead radio weatherman say, for example, that the "high tomorrow will be 65 with a low of 28." But when you walk out of the house the next morning you are hit with 40 degrees and blue northern. However, the weatherman was technically correct: At midnight it had been 65. That was, in fact, the day's high. What he didn't tell you was that the temperatures would plummet after midnight until it reaches 28 at 11:59 p.m.

So let's look at this graphic. On Thursday at 11:59 p.m., we know from the graphic that the temperature is predicted to be somewhere between 39-40.  But on Friday, which begins at midnight + 1 second after Thursday, the range is 30-28.
