The latest ENSO update from NOAA shows that neutral conditions are occurring in the eastern Pacific Ocean right now and are expected to continue for the next few months. When there is no El Niño or La Niña occurring, it is harder to make a useful prediction about what is likely to happen in the Southeast than when either of those states is happening. In neutral conditions, we are more likely to see wide swings in the weather over the winter season. One of the effects that this can have is the chance of a later-than-normal spring frost, although it does not happen in each neutral winter.
