I thought it might be interesting to look at the monthly outlooks from the Climate Prediction Center (CPC) on the first day of every month. Below are the graphics displaying departures from normal for both temperature and precipitation for September 2009. At the end of the month, if I remember, we’ll look back to check the accuracy of this outlook.
CPC Outlook for September 2009. Data are temperature departure from normal.
CPC Outlook for September 2009. Data are precipitation departure from normal.
As you can see, above average temperatures are expected in the desert southwest and northern New England. Above average precipitation is expected in Florida (read: tropical cyclones) and the Central Plains. Drier conditions are expected in Oregon, northern California, and northeastern Nevada. The “EC” notation indicates there are Equal Chances for above normal, neutral, and below normal conditions. In other words, anything could happen in those areas as far as the CPC is concerned.
We’ll take a look back at the end of the month and check in during the month, if warranted.
