It seems to be a trend the last couple weeks: tweets from the National Weather Service saying something about it still being warm.

It's mid-October and we're still seeing temps nearing 100 degrees. Phoenix is getting hotter sooner and the heat is staying longer.

But we already know this.

Data released from the National Weather Service shows the current "heat spell" is just a "continuation of long term trends," which they mentioned just last year in October.

NWS explained last year they looked at well-over a century's worth of data.

The graphs show Phoenix's first 110-degree temperature is coming, on average, 16 days earlier than it did a century ago.

And the last day of 110-degree weather? About 31 days later, according to the charts.

More than that, areas of the Southwest had some of the hottest summers on their records.

According to NWS, the Phoenix area had its fourth hottest period on record from June to August of this year.

Overall, the rest of Arizona, for that same period, ranked in the top six on record while it was the warmest ever for southeast California.

Moral of the story: Phoenix is staying hot longer than ever before.

Will the trend ever stop?
