Our Summer forecast is a blend of looking at the past weather data and changes in global circulation patterns. We have found recently that the changes in global circulation patterns, specifically La Nina and El Nino have consistent and repeated effects on our seasonal forecasts. La Nina is the cooling of the Pacific Ocean water near the Equator and South America. El Nino is the warming of the same water.

Our seasonal forecasts are based on our past weather history and changes in global circulations patterns. Last winter we were in a La Nina pattern, which just means the ocean water in the Pacific near the equator was cooler than normal. We then shifted back to normal this summer and are forecasted to shift back to La Nina conditions this upcoming winter. The fluctuation of these water temperatures is normal but it can affect what happens here each season.

TOPICS: WeatherForecastSummerTemperaturesPrecipitationEl NinoLa NinaTornadoes When we put together our seasonal forecasts, we generally look at 2 data sets. The first is our local weather history, what’s happened in our past. The second is changes in global circulation patterns. By this I mean El Nino and La Nina, which are fluctuations in the ocean water temperature in the Pacific near South America. Warmer than normal temps here is called El Nino, Cooler than normal is called La Nina.
