AUSTIN (KXAN) — The latest outlook from the Climate Prediction Center shows increasingly likely odds of wetter weather for the month ahead.

The previous April outlook released mid-March suggested a wet April was possible and this latest outlook adds even more confidence for higher rainfall in Central Texas.

April is typically not a wet month for Central Texas, it’s actually our third driest month on average.

Now that La Niña has ended and we’ve entered a “neutral” phase of ENSO, the temperature of the waters in the eastern equatorial Pacific has a much lower impact on the weather we see in Central Texas and indeed North America.

While odds favor wetter weather for April, we’re still expecting warmer-than-normal temperatures across most of the south and southeastern United States.
