The CPC notes that neutral water temperatures are still being found in the Pacific Ocean. Therefore, no influences are expected in June from an El Nino or La Nina. Forecasters relied heavily on current overall meteorological trends, along with weather model predictions. Soil moisture levels are high over portions of the Midwest, Mississippi Valley, and Great Plains. At this time of the year, this usually supports a trend of cooler and wetter than average weather.
