Why was this the hottest summer ever?

By Jamey Boyum - email

TYLER, TX (KLTV) - It's the hottest summer ever, and now, we have proof.

The National Weather Service reports the average temperatures in August set new records for Tyler, Longview, and Lufkin.

But, why? Why is East Texas an oven?

To find out why it's stayed hot,  I asked KLTV's very own Grant Dade, and as you can see, he loves green, because with it, he can show us anything...like what he's really good at: Explaining weather.

Grant says the sun doesn't heat up the air, it heats up the ground, and high pressure is pushing out all our chances of drenching rain.

"Ninety-nine percent of the water you would find normally in the ground is not there", says Grant.

No moisture equals hot dirt in the morning. It's a vicious cycle.

To explain exactly what he is talking about, Grant took the dirt's temperature. The thermo-pen settled at over 118 degrees. So the hot air came from the hot ground, which came from the high pressure.

What caused the high pressure?

Grant says a dry fall and winter came from what La Nina does best: A blocking weather pattern. Things stay the same.

So, much like a three year old asking why too many times...I ask, "What causes La Nina?"

"La Nina," says Grant, " is a cooling of the surface temperatures of the Eastern Pacific Ocean."

Grant says trade winds push warm surface water west which causes upwelling of cooler deep water.

It's all so simple. Our hot air came from hot ground, which came from high pressure, which came from La Nina, which came from cool water, which came from trade winds.

Grant had to leave before he told me where trade winds came from, but I think it's a grumpy troll with a giant fan on an uncharted Pacific Island....but I have been wrong before.
