It’s January 8, and the United States is currently experiencing the harshest winter in many years, and while I personally enjoy winter weather, I know that not all of us do. So, let’s take an early–very early–look at the 2010 summer forecast (June through August).
The coupled forecast system is something that I’ve talked about before on the blog; it’s a long-range forecast model used by the government to help with long-range forecasting. It is not the official NOAA forecast; it’s merely one of the tools that they use for making their official forecasts. Since the model creates a forecast for many months in advance, though, we can take a peek at what the computer model is projecting for the summer–a kind of sneak peek into lemonade and watermelon season.
Cooler and Wetter than Normal
The model is forecasting that temperatures will be below normal across much of the United States, with temperatures forecast to be significantly below normal in the middle of the country. Temperatures will be slightly above normal in South Texas, the coastal Pacific Northwest, and much of New England. (image below)
Precipitation is forecast to be less than normal in New England and parts of the Mid-Atlantic region while much of the remainder of the country, according to the model, will have more precipitation than normal. (image below)
If you’re shivering now, remember that a cooler-than-normal summer is a lot warmer than a cold winter! Hang in there.
The images are tough to see–I know. The post is based on the June through August maps, which are on the right side of the images below.
