A 45 Day Forecast? The models have (some) skill out 15 days or so, depending on the pattern, at least for precipitation and temperature for a specific point, but 45 days into the future? Sometimes we can detect trends, based on El Nino or La Nina, but a precise temperature/rainfall prediction for late September for a given town? Not possible, at least not with any demonstrable skill. Here's a post from meteorologist Dan Satterfield at AGU Blogosphere: "AccuWeather announced today that they are now producing “revolutionary” 45 day weather forecasts. Yes, you read that right, and while the public in general has a rather low understanding of science, I don’t think most people are that gullible. My first thoughts were that it might be a way of getting some free advertising, but perhaps they’re really serious. Let me first be clear and tell you that synoptic weather forecasts are about 90% accurate out to 1 day, and are fairly accurate out to 5 days most of the time. Beyond 7 days the best forecast is to use is the 30 year averages..."
