El Nino is officially underway. Here’s what that means for the weather
After months of anticipation, El Ni?o has officially developed and will have a heavy hand in shaping the weather patterns around the world into 2024.
On Thursday morning, NOAA's Climate Prediction Center announced that "El Ni?o conditions are present and are expected to gradually strengthen into the Northern Hemisphere for the winter of 2023-24."
El Ni?o is a regular climate phenomenon in the eastern Pacific Ocean when water temperatures near the equator are at least 0.9 of a degree F (0.5 of a degree C) above the historical average for a three-month period. The extended period of warmth in this region of the ocean alters the jet stream and the overall weather patterns across North America.
El Niño is coming. Here’s what that means for weather in the U.S.

How the Average High is Sort of A Lie
The average high temperature reported on the news is actually a lie. 🌡
They don’t usually report the average high but the climate normal high, which is not the average of recorded high temperatures over the past thirty years but a smoothed data set that has various adjustments to account for missing data and errors in measurements, along with suppressing other statistical anomalies like record breaking heat or cold on any one particular day.

So the average high is kind of like calling twinkies a food.
