WSI News Release - 07.19.10
Andover, MA: WSI (Weather Services International) expects the upcoming period (August-October) to average warmer than normal across most of the US, with the exception of parts of the Southeast and California coastal cities. The WSI seasonal outlooks reference a standard 30-year normal (1971-2000).
"The combination of a newly-emerging La Nina event, a relatively cold north Pacific, and a record warm north Atlantic are quite bullish for a very warm late summer and early fall period," said WSI Chief Meteorologist Dr. Todd Crawford. On the other hand, very high soil moisture levels across the Plains, along with a lack of any significant drought conditions in the US, will temper the overall magnitude of the heat a little. For the August-October period as a whole, we are forecasting 571 population-weighted cooling degree days, 15% more than both last year and the 1971-2000 mean."
